the reference number to check the translation in the IBM Systems Safety Notices,
G229-9054 manual.
The sections that follow define each type of safety notice and give examples.
Danger notice
A danger notice calls attention to a situation that is potentially lethal or extremely
hazardous to people. A lightning bolt symbol always accompanies a danger notice
to represent a dangerous electrical condition. A sample danger notice follows:
DANGER: An electrical outlet that is not correctly wired could place
hazardous voltage on metal parts of the system or the devices that
attach to the system. It is the responsibility of the customer to ensure
that the outlet is correctly wired and grounded to prevent an electrical
shock. (D004)
Caution notice
A caution notice calls attention to a situation that is potentially hazardous to
people because of some existing condition, or to a potentially dangerous situation
that might develop because of some unsafe practice. A caution notice can be
accompanied by one of several symbols:
If the symbol is... It means...
A generally hazardous condition not represented by other
safety symbols.
This product contains a Class II laser. Do not stare into the
beam. (C029) Laser symbols are always accompanied by the
classification of the laser as defined by the U. S.
Department of Health and Human Services (for example,
Class I, Class II, and so forth).
A hazardous condition due to mechanical movement in or
around the product.

Data storage values
TS3500 Tape Library documentation displays data storage values using both
decimal (base-10) prefixes and binary (base-2) units of measurement.
Decimal units such as K, MB, GB, and TB have commonly been used to express
data storage values, though these values are more accurately expressed using
binary units such as KiB, MiB, GiB, and TiB. At the kilobyte level, the difference
between decimal and binary units of measurement is relatively small (2.4%). This
difference grows as data storage values increase, and when values reach terabyte
levels the difference between decimal and binary units approaches 10%.
To reduce the possibility of confusion, the TS3500 Tape Library documentation
represents data storage using both decimal and binary units. Data storage values
are displayed using the following format:
#### decimal unit (binary unit)
By this example, the value 512 terabytes is displayed as:
512 TB (465.6 TiB)
Table 2 compares the names, symbols, and values of the binary and decimal units.
Table 3 shows the increasing percentage of difference between binary and decimal
units.

Chapter 1. Introduction
This chapter introduces the IBM System Storage TS3500 Tape Library, machine type
3584, also referred to as the 3584 Tape Library. The information in this chapter is
specific to the TS3500 Tape Library with the Advanced Library Management
System (ALMS).
Overview
This topic describes the IBM System Storage TS3500 Tape Library, a highly scalable,
stand-alone device that provides reliable, automated tape handling and storage for
both mainframe and Open Systems environments.
Figure 2 on page 2 shows a 6-frame version of the TS3500 Tape Library. An
individual library, or library string, consists of one base frame and up to 15
expansion frames and can include up to 192 tape drives and more than 20 000 tape
cartridges. The flexibility to connect multiple library strings to create a shuttle
complex greatly increases opportunities for growth, as well as the maximum
cartridge capacity. In addition to scalability, the TS3500 Tape Library offers the
following enhancements:
v Enhanced data accessibility through dual accessors that increase speed and
provide failover protection
v Enhanced data security through support for tape drive encryption and
write-once-read-many (WORM) cartridges
v Increased storage capacity with high-density (HD) frames that greatly increase
capacity without requiring more floor space
v Increased growth flexibility with shuttle technology, even in physically
constrained environments
v Greatly increased cartridge capacity in a shuttle complex without the need for
additional tape drives
These features are explained in greater detail throughout this chapter.

Notes:
|
1. In order to support code level 9500 or higher, all node cards in the library must be xx3-equivalent node cards.
For xx2 models, this requires a xx3 model conversion OR the enhanced node card(s) feature (FC 1700 or 1701).
|
|
2. In order to increase the maximum number of cartridges to more than 6 887, or to support a shuttle complex,
|
logical libraries must use LTO Ultrium 4, 3592 E05, or later tape drives as control path drives. In order to
support more than 6 887 cartridges, Ultrium 4 control path drives require a minimum code level of 97F0. For
|
logical libraries with shuttle stations assigned, Ultrium 4 control path drives require a minimum code level of
|
A480 and Ultrium 5 control path drives require a minimum code level of B170.
|
3. The maximum native capacity figures are based on library configurations with high density (HD) frames and all
|
Ultrium 6 or 3592 E07 tape drives. In addition, the figures for libraries with Model SC1 (shuttle connection) are
|
based on the maximum shuttle complex configuration.
4. In order to support Ultrium 6 tape drives, libraries with an L32 frame require enhanced grippers (FC 2205 or
|
2304).

For detailed information regarding tape drives supported by the TS3500 Tape
Library, and the data rate and capacity for these drives, see “Supported tape
drives” on page 17. For information regarding supported tape media, refer to
“Supported tape cartridges” on page 25. For details regarding frame models and

complex and Model SC1, refer to “Structure of the shuttle complex” on page 15.
Structure of the library
This topic defines base and expansion frames and describes the models of the
TS3500 Tape Library.
The basic TS3500 Tape Library is a single storage unit known as the base frame
(Models L32, L52, or L53 for LTO Ultrium tape drives, or Models L22 or L23 for
3592 tape drives). The library's scalability allows you to increase capacity by
adding up to 15 additional storage units, called expansion frames (Models D32, D52,
D53, and S54 for LTO Ultrium tape drives or Models D22, D23, and S24 for 3592
tape drives). The frames join side by side, with the base frame on the left and the
expansion frame on the right. The additional expansion frames are supported by a
common cartridge accessor that requires no pass-through mechanism. Frame
Models D22, D23, D32, D52, and D53 can contain up to 12 Ultrium tape drives or
3592 tape drives, but cannot contain a mix of both.
High-density frames, referred to hereafter as HD frames, greatly increase library
capacity. HD frame Model S54 can contain up to 1 320 Ultrium tape cartridges and
HD frame Model S24 can contain up to 1 000 IBM 3592 tape cartridges. The HD
frames offer increased capacity without increasing frame size or required floor
space by using high density storage slots for tape cartridges, referred to hereafter
as HD slots. For more information, see “High density technology” on page 9. In
Chapter 1. Introduction 3
Page 28
addition, HD frames can support shuttle stations that enable connections between
multiple TS3500 Tape Library strings. For more information, see “Structure of the
shuttle complex” on page 15.
Note: Base frame models L22, L23, L52, L53, and L32 are referred to hereafter as
base frames, unless model-specific information is discussed. Expansion frame
models D22, D23, D52, D53, D32, S24, and S54 are referred to hereafter as expansion
frames, unless model-specific information is discussed.
The TS3500 Tape Library features an optional second cartridge accessor. If you
order dual accessors, two frames that are used as service bays are required. Service
bay A is known as Model HA1 and service bay B is a Model D23, D22, D52, D53,
S24, or S54 frame. For more information, see “Dual accessors and service bays” on
page 7.
Note: In order to support mixed media in an HD library with dual accessors,
service bay B must be a model Dxx frame. This configuration requires feature code
1697, which ensures that the service bays provide both LTO and 3592 HD test slots.
For bulk media handling, the TS3500 Tape Library supports four I/O stations in
newly purchased Models D23 and D53 frames. The D-frame with I/O installed is
comprised of four independently accessible I/O station doors with a total of 64
slots (16 in each I/O station door). Additionally, two LED indicators are provided
for each I/O station in a D-frame in order to indicate if the I/O station is empty or
full and if the I/O station door is locked or unlocked. This plant feature reduces
the frame storage slot capacity by 160 for a Model D23 and by 176 for a Model
D53. The I/O stations increase the maximum library I/O slot capacity from 32 to
224. The multiple I/O stations can double the maximum insert and eject
throughput since both accessors can be used. The D23 and D53 models remain
compatible with existing Models L22, L32, L52, D22, D32, and D52.
The models of the TS3500 Tape Library vary depending on the type of media they
contain and whether the frame is a service bay, a base frame, or an expansion
frame. Table 5 lists each frame and its characteristics.

|
2. In order to support Ultrium 6 tape drives, libraries with an L32 frame require enhanced grippers (FC 2205 or

2304).
Models L22, D22, L23, D23, L52, D52, L53, D53, S24, and S54 are compatible with
Models L32 and D32, but require additional features because they use different
side and rear covers. If you change from a Model L32 or D32 to a Model D22, D23,
D52, D53, S24, or S54 (or from a Model D22, D23, D52, D53, S24, or S54 to a Model
D32) within the same library you may also need the appropriate side covers.
When expanding an installed library, an expansion frame is installed at the end of
the library string (end of the library string refers to the very last frame or, if
requested by the customer, the last frame before service bay B). In order to have
the expansion frame installed somewhere other than the end of the library string,
the IBM service representative must obtain a service contract to uninstall additional
frames as necessary to accommodate the customer's request.
The IBM System Storage Tape Library Specialist Web interface and 10/100 Ethernet
support are included with Models L22, L23, L52, and L53. For Model L32, they are
available as feature codes 1662 and 1660, respectively.
Figure 3 shows an example of a base frame and an expansion frame. A Model L23
or L53 (base frame) is on the left. A Model D23 or D53 (expansion frame) is on the
right and attaches to the base frame.

Dual accessors and service bays
This topic describes dual accessors and service bays and how they can enhance
library performance.
When an optional second accessor is installed, the TS3500 Tape Library features
enhanced availability by utilizing an additional accessor. The additional accessor
enables the library to operate without disruption if any component of the working
accessor fails.
If the library is installed with the optional second accessor, cartridge mount
performance is also optimized. (A mount occurs when the accessor removes a
cartridge from a drive, returns it to its storage slot, collects another cartridge from
a random storage slot, moves it, and loads it into the drive.) The second accessor is
part of feature code 1440 (Service Bay B Configuration), which can be ordered with
expansion frames used as service bay B. If you order a second accessor you must
also order a 3584 high availability (HA1) frame, which is also known as service
bay A.
As you view the library from the front, service bay A (the HA1 frame) is on the far
left and service bay B is on the far right. Figure 4 shows the location of service
bays in the TS3500 Tape Library.
Figure 4. Location of service bays in the TS3500 Tape Library
When dual accessors are installed and an attached host issues a command for
cartridge movement, the library automatically determines which accessor can
r8a00005
Chapter 1. Introduction 7
Page 32
perform the mount in the most timely manner. If the library's primary accessor
fails, the second accessor assumes control and eliminates system outage or the
need for operator intervention.
Although the library uses defaults to specify the zones (areas) in which the
accessors operate, you can specify particular zones by using the Tape Library
Specialist Web interface. This process is called setting the preferred zone. For
details, see the section about setting the preferred zone in the IBM System Storage
TS3500 Tape Library with ALMS Operator Guide.
Service bay A (the HA1 frame) contains only gripper test slots (1 in Figure 5) for
diagnostic cartridges. Service bay B contains gripper test slots 2 for diagnostic
cartridges, and also contains unusable storage slots 3. The storage slots in service
bay B are not used if the frame is configured as a service bay. Figure 5 shows the
location of slots in an example of a service bay.
Figure 5. Cartridge slots in the service bays of the TS3500 Tape Library
If you already have an installed TS3500 Tape Library and you want to add a
second accessor, your IBM service representative can add the accessor and its
service bays. Converting from a single accessor to a dual accessor library requires
that the service representative take down the entire library.
If your library already contains the service bays and you decide to add one or
more expansion frames, your IBM service representative can convert service bay B
to an expansion frame, add the new frame or frames to the right, and convert the
last frame on the right to service bay B. This process requires no scheduled
downtime. (Downtime is designed to be less than one hour.) To convert the existing
service bay to an expansion frame, the service representative removes the test slots
and replaces them with storage slots. Similarly, to convert an expansion frame to a
service bay, the service representative removes specific storage slots and replaces
them with the test slots. For more information, contact your IBM service
representative.

v If you convert an existing HD frame from a service bay to an expansion frame, a
Capacity on Demand feature (1645 or 1646) is required in order to use the full
capacity of the frame. If an HD frame is ordered to be used as service bay B, it
does not require a Capacity on Demand feature.
v In order to support mixed media in an HD library with dual accessors, service
bay B must be a model Dxx frame. This configuration requires feature code 1697,
which ensures that the service bays provide both LTO and 3592 HD test slots.
v Expansion frame Model D32 cannot be used as service bay B.
For information about library availability and performance, see “Library
performance” on page 83.
High density technology
The TS3500 Tape Library offers high-density, storage-only frame models (HD
frames) designed to greatly increase storage capacity without increasing frame size
or required floor space. The new HD frames (Model S24 for 3592 tape cartridges
and Model S54 for LTO Ultrium tape cartridges) contain HD storage slots.
HD slots contain tape cartridges in a tiered architecture. The cartridge immediately
accessible in the HD slot is a Tier 1 cartridge. Behind that is Tier 2 and so on. The
maximum tier in an LTO Ultirum (Model S54) HD slot is Tier 5. The maximum tier
in a 3592 (Model S24) HD slot is Tier 4 because the 3592 tape cartridge is slightly
longer than the LTO Ultrium cartridge. The single-deep slots on the door side of
HD frames are referred to as Tier 0 slots. On the left, Figure 6 on page 10 shows
the inside of an HD frame from the side. On the right, Figure 6 on page 10 shows a
top-down view of one row of an HD frame with cartridges in Tiers 0 (door side),
1, 2, and 3.
Chapter 1. Introduction 9
Page 34
Figure 6. The HD frame (left) and top-down view of row in an HD frame (right)
Attention: The HD slots have a constant force spring for maintaining forward
pressure on the tape cartridges. Use caution when inserting or removing cartridges
from HD slots.
HD frame model S24 provides storage for up to 1 000 IBM 3592 tape cartridges.
HD frame model S54 provides storage for up to 1 320 LTO Ultrium tape cartridges.
The base capacity of Model S24 is 600 cartridges, which are stored in Tiers 0, 1,
and 2. The base capacity of Model S54 is 660 cartridges, which are stored in Tiers
0, 1, and 2. In order to increase capacity to the maximum for each frame, it is
necessary to purchase the High Density Capacity on Demand (HD CoD) feature.
This feature provides a license key that enables you to utilize the storage space
available in the remaining tiers. For more information, see “High Density Capacity
On Demand” on page 55.
Note: These numbers represent raw capacity and do not reflect actual
recommended capacity. It is recommended that actual capacity does not exceed
99% of the raw capacity due to the need to maintain unused slots in order to
perform a shuffle operation.
In HD frames, the cartridge accessor performs a shuffle operation in order to access
the cartridges stored in Tier 2 and beyond. A shuffle is the process of moving
cartridges in lower tiers into the gripper, or other available slots, in order to access
cartridges in higher tiers (Tier 2 or greater). In order to reduce the occurrence of
shuffle operations and to take advantage of repeated accesses of certain cartridges,
the role of cartridge cache is assigned to all single-deep (Tier 0) slots in an HD
library. In order to maintain efficient shuffle operations, the library performs a load
balancing of the tiers, which stores cartridges across all HD slots in the library
string. In other words, all HD slots are filled to a minimum tier level until that tier
10 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 35
is full across the library. For more information about HD frames and library
performance, see “Library performance” on page 83.
HD frame models S24 and S54 can be attached to installed Dx2, Dx3, Lx2, and Lx3
frames and these frames can be intermixed in the same library configuration. In
addition, HD frame models S24 and S54 can support shuttle stations in order to
attach multiple library strings in a shuttle complex. For more information about a
shuttle complex, see “Structure of the shuttle complex” on page 15.
Notes:
v If you convert an existing HD frame from a service bay to an expansion frame, a
Capacity on Demand feature (1645 or 1646) is required in order to use the full
capacity of the frame. If an HD frame is ordered to be used as service bay B, it
does not require a Capacity on Demand feature.
v In order to support mixed media in an HD library with dual accessors, service
bay B must be a model Dxx frame. This configuration requires feature code 1697,
which ensures that the service bays provide both LTO and 3592 HD test slots.
v When expanding an installed library, an expansion frame is installed at the end
of the library string (end of the library string refers to the very last frame or, if
requested by the customer, the last frame before service bay B). In order to have
the expansion frame installed somewhere other than the end of the library
string, the IBM service representative must obtain a service contract to uninstall
additional frames as necessary to accommodate the customer's request.

Components of the library
This topic describes the major parts of the TS3500 Tape Library.
The TS3500 Tape Library consists of the major components shown in Figure 7 on
page 14 (the figure depicts Model L53). For a more complete description of each
component, see the appropriate sections in the IBM System Storage TS3500 Tape
Library with ALMS Operator Guide.
12 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 37
1 Library frames
The base frame (Models L53, L52, or L32 for Ultrium tape drives, and Models L23 or L22 for 3592 tape
drives) and the expansion frame (Models D53, D52, D32, or S54 for Ultrium tape drives, and Models D23,
D22, or S24 for 3592 tape drives). Each frame contains a rail system, cartridge storage slots, and up to 12
tape drives. The storage-only frames, Models S24 and S54, do not contain tape drives.
2 Rail system
The assembly on which the cartridge accessor moves through the library. The system includes the top and
bottom rails.
3 Cartridge accessor with optimized dual-gripper transport mechanism
The assembly that moves tape cartridges between storage slots, tape drives, and the I/O stations. An
optional second accessor is available with two service bays. For libraries that have mixed drive types, the
optimized dual gripper can handle both Ultrium and 3592 tape cartridges.
4 Accessor controller
A circuit board that facilitates all accessor motion requests (such as calibrations, moves, and inventory
updates). If your library includes a second accessor, it will also have a second accessor controller.
5 Cartridge storage slots
Cells that are mounted in the TS3500 Tape Library and used to store tape cartridges.
6 IBM LTO Ultrium tape drives or 3592 tape drives
Mounted in the TS3500 Tape Library, one or more units that read and write data that is stored on tape
cartridges. IBM LTO Ultrium tape drives and 3592 tape drives may not be mixed in the same frame. IBM
Ultrium tape drives use LTO Ultrium tape cartridges; 3592 tape drives use IBM 3592 Tape Cartridges.
7 Front door
The front door of any frame. When you order the Capacity Expansion Feature for the Model L22, L32, or
L52, the storage slots inside the front door become enabled and can increase the tape library's capacity.
8 Door safety switch
A device in each frame that shuts down the motion power to the cartridge accessor whenever the front door
is opened.
9 I/O stations
Up to two cartridge compartments on the front door of base frames of the TS3500 Tape Library that allow
you to insert or remove tape cartridges without the library performing a reinventory of the frame.
10 Operator panel and operator panel controller
Located on the front of the base frame, the operator panel is the set of indicators and controls that lets you
perform operations and determine the status of the library. The panel consists of the library power switch, a
power-on indicator, a touch screen liquid crystal display (LCD), and the controller for the I/O stations. The
operator panel controller is a circuit board that facilitates communication between the operator panel and
the accessor controller.
11 Enhanced frame control assembly
An assembly of components that facilitate RS-422 communication between the drives in a frame and the
accessor controller and operator panel controller. Only Models L23, D23, L53, and D53 are equipped with
the enhanced frame control assembly, which includes two power supplies, both of which can provide power
to the library and all drives in a frame.
12 Patch panel
A panel that houses the cable connections for the drives that use Fibre Channel interfaces. If frame is
equipped with the TS7700 backend switches (not shown), the patch panel is removed.
13 Power cable hole
An optional, capped opening for a library whose power cable attaches to an outlet mounted above the
library.
14 Fibre Channel cable hole
An optional, capped opening for a library whose Fibre Channel cables are routed above the library.

Structure of the shuttle complex
In order to meet the needs of large data center archives that have to store
increasing amounts of data, the TS3500 Tape Library offers shuttle technology that
enables flexible library growth on a z-axis. This growth flexibility, enabled by
shuttle connections between HD libraries, allows a higher maximum capacity for a
single library image of multiple TS3500 library strings. This flexibility also
accommodates constrained data center layouts that do not have room to expand on
the x-axis, as well as data centers with large archives that exceed the maximum
cartridge count of an individual TS3500 Tape Library string.
Unlike passthrough automation technologies that pass tape cartridges through
intermediary libraries, the TS3500 Tape Library transports tape cartridges in shuttle
cars that pass over the libraries. This method of transporting cartridges is called
direct flight. With the direct flight capability, if there is no drive available in the
home logical library, the cartridge is moved across a shuttle connection to a logical
library with an available drive. This configuration of interconnected parallel library
strings is called a shuttle complex. The components of a shuttle complex (shown in
Figure 8 on page 16) are described below:
1 Shuttle station
The shuttle station mounts on top of an HD frame. It consists of a base
pad and a shuttle slot. The shuttle slot docks into the base pad. When the
shuttle slot is all the way down into the frame station it can accept or
deliver a cartridge. Each shuttle station has its own import/export element
(IEE) address.
2 Shuttle span
One or more shuttle spans are linked together in order to form a shuttle
connection between HD frames in parallel library strings. Shorter shuttle
spans support distances between library strings ranging from 762 mm (30
in) to 1 524 mm (60 in). Longer shuttle spans support distances between
library strings ranging from 1 524 mm (60 in) to 2 743.2 mm (108 in).
3 Shuttle connection
A shuttle connection is comprised of one shuttle car, two or more shuttle
stations, and one or more spans between these shuttle stations. Each
shuttle connection supports one shuttle car.
Shuttle car (not shown)
The shuttle car is the mechanism that carries one tape cartridge through
the shuttle connection to another library string. Each shuttle car carries one
tape cartridge at a time.
Chapter 1. Introduction 15
Page 40
Figure 8. TS3500 Tape Library shuttle complex
Physical configuration of the shuttle complex
A shuttle complex is comprised of between two and 15 parallel library strings that
are interconnected by shuttle connections between HD frames. Each library string
in a shuttle complex has access to one or more shuttle cars that each provide at
least one direct route to each of the remote library strings. (At least two direct
routes are recommended for redundancy.)
A shuttle complex supports library strings with varying numbers of frames to the
left or right of each connection. A shuttle complex also supports shuttle
connections with varying numbers of spans. This support enables flexible shuttle
complex configurations in order to accommodate most data center arrangements. It
is required that the front doors of each library string in the shuttle complex face
the same direction.
Shuttle connections attach to shuttle stations that are mounted on HD frames.
Logical configuration of the shuttle complex
A shuttle complex enables multiple TS3500 Tape Library strings to appear as a
single library image to the host. Each library string is still its own SCSI library,
however a library manager application such as HPSS, aggregates the multiple SCSI
libraries into a single library image. This allows sharing of tape drive resources
across multiple logical libraries in different library strings.
Each library string in a shuttle complex contains up to 192 logical libraries. Each
shuttle station can be assigned to one logical library per library string or can
remain unassigned. It is required that all shuttle stations on the same connection
are assigned to logical libraries of the same media type. Shuttle stations are
assigned to logical libraries through the TS3500 Tape Library web specialist
interface.

Supported tape drives
The LTO Ultrium tape drives and the 3592 tape drives are high-performance,
high-capacity data-storage units that can be installed in the TS3500 Tape Library.
Up to 12 drives can be installed in each base and expansion frame of the library,
but the two types of drives cannot be mixed in the same frame. You can identify a
drive by examining the logo at the front of the drive canister or by inspecting the
label at the rear of the drive canister.
Note: No drives are installed in the storage-only HD frames (Models S24 and S54).

You or your IBM service representative can update firmware for the LTO Ultrium 2
and newer Ultrium tape drives and all 3592 tape drives without scheduling
downtime. This enhancement is called a nondisruptive drive firmware update.Itis
available through the IBM System Storage Tape Library Specialist web interface
and (for IBM service representatives) through CETool, but is not supported by the
SCSI interface. For more information, go to the section about updating drive
firmware in the IBM System Storage TS3500 Tape Library with ALMS Operator Guide.

There are six generations of Linear Tape-Open (LTO) Ultrium tape drives. The
newest of these drives, the IBM System Storage TS1060 Tape Drive Model F6A, is a
dual-ported drive that facilitates 8 Gbps Fibre Channel connectivity. This drive is
also known as the Ultrium 6 tape drive and is differentiated by its machine type
and model number 3588 F6A.
Note: In order to support Ultrium 5 and later tape drives, all node cards in the
library must be model xx3-equivalent node cards. For node cards in model xx2
frames, this requires an xx3 model conversion OR the enhanced node card(s)
freature (FC 1700 or 1701).
The six generations of LTO Ultrium drives are listed below:
v IBM System Storage TS1060 Tape Drive (8 Gbps, dual ports)
v IBM System Storage TS1050 Tape Drive (8 Gbps, dual ports)
v IBM System Storage TS1040 Tape Drive (4 Gbps, single port)
v IBM System Storage TS1030 Tape Drive Model F3B (4 Gbps, single port)
v IBM System Storage TS1030 Tape Drive Model F3A (2 Gbps, single port)
v IBM TotalStorage LTO Ultrium 2 Tape Drive (2 Gbps, single port)
v IBM TotalStorage LTO Ultrium 1 Tape Drive (1 Gbps, single port)
18 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 43
You can identify all Ultrium 2 and later Ultrium tape drives by the logo at the
front of the drive or by the label at the rear of the drive's canister. You can identify
the Ultrium 1 tape drive by the label at the rear of its canister. An Ultrium 3
write-once-read-many (WORM)-capable drive can be identified by the level of code
it contains. If the code level is 54K1 or higher, the Ultrium 3 drive is capable of
WORM functionality. Ultrium 3 and newer tape drives with WORM capability can
recognize WORM-compatible media.
Ultrium 3 drives with WORM-capable firmware and newer Ultrium tape drives
read and write non-WORM media. This means that you can load WORM-capable
firmware on your Ultrium 3 and newer tape drives and use any media that are
supported by these drives. In this case, only the data that is written on the WORM
media is treated as WORM data; data written on other types of media can be
overwritten.
Ultrium tape drives do not read from or write to 3592 tape cartridges, and 3592
tape drives do not read or write to Ultrium tape cartridges. Refer to “Mixing
media in drives” on page 37 for detailed information about cartridge and drive
compatibility.
The Ultrium tape drives can read tapes that have been written by non-IBM
Ultrium drives. They also write to tapes that can be read by non-IBM Ultrium
drives.
All generations of Ultrium tape drives and cartridges can reside in the same frame.
When a cartridge is labeled according to proper IBM bar code label specifications,
the last character of its volume serial (VOLSER) number indicates the generation of
the medium. For example, a cartridge with a VOLSER of 000764L5 is an Ultrium 5
cartridge; a cartridge with a VOLSER of 000764L4 is an Ultrium 4 cartridge; and so
forth.
To enhance library performance, Ultrium 2 and newer Ultrium tape drives include
speed matching, channel calibration, and power management. Speed matching
dynamically adjusts the drive's native (uncompressed) data rate to the slower data
rate of a server. Channel calibration customizes each read/write data channel for
optimum performance. The customization enables compensation for variations in
the recording channel transfer function, media characteristics, and read/write head

Encryption
Ultrium 4 and later tape drives are encryption capable, which means they can
convert data into a cipher that ensures data security. To perform encryption, the
drive must be encryption enabled by your selection of one of three methods of
encryption management. Two of these methods, system-managed and
library-managed encryption, require the purchase of FC 1604 (Transparent LTO
Encryption). A key is required to encrypt and decrypt the data. How a key is
generated, maintained, controlled, and transmitted depends on the operating
environment where the Ultrium 4 or later tape drive is installed. Some data
management applications are capable of performing key management. For an
alternative solution, IBM provides a key manager that works in conjunction with
the keystore of your choice to perform all necessary key management tasks. There
is no recovery for lost encryption keys. For more information about encryption, see
Chapter 8, “Tape encryption overview,” on page 215. Also refer to the IBM
Chapter 1. Introduction 19
Page 44
Encryption Key Manager and Tivoli®Key Lifecycle Manager publications listed in
the Related information section. To choose a method of encryption management,
refer to “Managing encryption” on page 216.
To ensure that your tape drive conforms to IBM's specifications for reliability, use
only IBM LTO Ultrium tape cartridges. You can use other LTO-certified data
cartridges, but they might not meet IBM standards of reliability.
Refer to “Drive performance” on page 79 for Ultrium tape drive performance
specifications.
3592 tape drives
There are four generations of 3592 tape drives: TS1140 (Model E07), TS1130
(Models E06 and EU6), TS1120 (Model E05), and J1A. All generations of 3592 tape
drives and cartridges can reside in the same TS3500 Tape Library frame. Each
generation of drive offers an increased data rate and increased native capacity from
the previous model, in addition to other enhancements. Each generation of drive
also offers dual-port Fibre Channel host attachment interfaces. This feature
provides flexibility in an Open Systems environment because the drives can
directly attach to Open Systems servers with Fibre Channel attachments. All
TS1120 and later tape drives are encryption capable, however some TS1120 tape
drives require feature code 5592 or 9592 in order to be encryption capable. Refer to
Table 7 for details about these and other 3592 tape drive features. For information
about encryption, refer to Chapter 8, “Tape encryption overview,” on page 215.
Note: The 3592 EU6 tape drive is a 3592 E05 tape drive canister upgraded to
contain a Model E06 drive through the Miscellaneous Equipment Specification
(MES) process. The EU6 model name is only used when information specific to the
Model EU6 is discussed.
All 3592 tape drives include an RS-422 library interface port for communication
with the TS3500 Tape Library. The 3592 tape drives use the Statistical Analysis and
Reporting System to isolate failures between media and hardware. The TS1130 and
TS1140 tape drives (3592 Models E06 and E07) also come with an Ethernet port,
however use of this port for service or remote monitoring is not supported in a
TS3500 Tape Library environment.
A 3592 tape drive cannot read or write to a 3590 High Performance Cartridge Tape
(media type J) or to a 3590 Extended High Performance Cartridge Tape (media
type K).
Table 7 shows the basic features of each generation of the 3592 tape drive. Refer to
“Drive performance” on page 79 for additional 3592 tape drive performance
specifications.

The 3592 tape drives provide the following performance, capacity, and availability
features:
N+1 power supplies
When installed in the TS3500 Tape Library frame, this helps to increase
drive availability in the event of a power failure.
Media reuse
The 3592 tape drives can reuse different types of tape and multiple
densities (logical formats) across various drive generations. Certain models
can only support a subset of densities (such as the 3592 J1A tape drive,
which can only read and write at a single density), while the later tape
drives can read and write at multiple densities. Enterprise format 1
Chapter 1. Introduction 21
Page 46
(EFMT1) records 512 tracks on 8 channels. Enterprise format 2 (EFMT2)
records 896 tracks on 16 channels. Enterprise format 3 (EFMT3) records
1152 tracks on 16 channels. Enterprise format 4 (EFMT4) records 2560
tracks on 32 channels. These logical formats can be divided into multiple
sub-format options, such as segmentation and capacity scaling. For more
information about capacity scaling and segmentation, refer to “Capacity
scaling and segmentation” on page 176. For a complete matrix of read and
write compatability by cartridge and format type, refer to “Mixing media
in drives” on page 37.
Speed matching
When operating in a host environment where the net host data rate is less
than the maximum drive native data rate, 3592 tape drives automatically
perform dynamic speed matching to minimize backhitches. Dynamic speed
matching adjusts the native data rate of the drive as closely as possible to
the net host data rate (after data compressibility has been factored out). A
reduction in backhitches improves system performance.
HRTD The HRTD directory structure, located in 3592 tape drives, allows the drive
to have fast and consistent nominal and average access times for locate
operations.
Channel calibration and on-the-fly adaptive equalization
To gain optimum performance, channel calibration allows the drive to
automatically customize each read and write data channel. The
customization compensates for variations in the recording channel transfer
function, for media characteristics, and for read and write head
characteristics. Initial calibration settings are calculated and stored at the
time of manufacture. For optimum error rate performance, TS1120 and
later tape drives also use on-the-fly adaptive equalization hardware on an
ongoing basis to adjust the read equalization response.
Recursive accumulating backhitchless flush
The TS1120 and later tape drives use an algorithm known as recursive
accumulating backhitchless flush (or non-volatile caching) to increase
effective data rate performance from host servers that force explicit
synchronize operations during write operations.
Backhitchless backspace
Backhitchless backspacing enables some backspace operations to be
virtualized without physical backhitching. If you write and overwrite
multiple trailer labels, this firmware feature provides major performance
improvements. For more information, refer to the appendix about WORM
behavior in the IBM System Storage 3592 Tape Drive SCSI Reference.
Capacity scaling
If you want to exchange capacity for improved access times, 3592 tape
drives support multiple format options, such as scaling and segmentation
modes. These tape drives can sense and report the scaling state of current
medium by using the SCSI Mode Sense command and specifying Mode
Page X'23'. Capacity scaling is only offered on the JA, JB, and JC media
types. For the exact Mode Select commands and settings necessary to
invoke scaling, refer to the IBM System Storage TS3500 Tape Library SCSI
Reference.
WORM
The 3592 tape drives support write-once-read-many (WORM) behaviors
and format attributes. Four WORM cartridge types are supported: JW (full
length), JR (short length), JX Extended WORM cartridge (for TS1120,
22 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 47
TS1130, and TS1140 tape drives), and JY Advanced WORM cartridge (for
TS1140 tape drives). WORM cartridges are factory-formatted as WORM
cartridges and may not be converted to data cartridges. The 3592 tape
drives allow append operations to data already on WORM cartridges, but
do not allow data to be overwritten under any circumstances.
Capacity-based and position-based LEOT reporting
The TS1120 and later tape drives use enhanced logic to report logical
end-of-tape (LEOT) data. The drive reports LEOT based on a combination
of indicators of capacity-based LEOT and position-based LEOT. These
drives monitor the total accumulated physical tape files written to the
cartridge and report the LEOT based on the capacity-based LEOT value,
rather than reporting LEOT based on the physical position on the tape
(position-based LEOT). To summarize, this technique reports LEOT based
on the amount of compressed data that is recorded to the cartridge and
reduces the variation in the amount of data recorded before LEOT is
issued. For applications that use LEOT to stop the write process, a more
consistent capacity is recorded to the media. For a higher percentage of the
time, this process allows tape copies to complete without overflow.
Enhanced format for recording error-correction codes (ECCs)
The logical formats of TS1120 and later tape drives offer improved
error-correction-code capabilities over the 3592 J1A and LTO formats by
increasing the power of one of the two orthogonal Reed-Solomon ECCs
that protect the data on tape. The correction power of the inner code is
approximately double that of the 3592 J1A and thus offers superior
reliability of the data.
Drive mechanical and electrical reliability
The mechanism of the TS1120 and later tape drives is specified at a
mean-cycles-between-failure rate of 300,000 cycles, which is the highest
reliability rating in the industry. The mechanism contains special
mechanical and electrical features to prevent damage to the media on
power-down or reset. These features also prevent the dropping of the
leader pin or other thread failures during similar interruptions. It also
tolerates extremely high vibration and shock environments without data
loss or degraded operation.
Multiple subsystem and automation support
The 3592 tape drives and their cartridges support multiple automation
libraries and can be easily transported between environments.
Data compression
The 3592 tape drives use the data-compression method known as
streaming lossless data compression algorithm. The compression logic for
TS1120 and later tape drives operates at more than twice the overall
transfer rates of the 3592 J1A tape drive.
Data buffer with read ahead feature
The 3592 J1A tape drive includes a data buffer of 134.22 MB (128 MiB). The
TS1120 tape drive includes a data buffer of 536.87 MB (512 MiB). The
TS1130 tape drive and TS1140 tape drive each include a data buffer of 1.07
GB (1 GiB). Along with enabling performance characteristics in buffered
Write and Read commands, the data buffer also supports a Read Ahead
feature. When the drive processes a command to locate or read a block, the
drive automatically continues to stream down the tape and read ahead
until the data buffer is full. This allows subsequent Locate or Read
commands to be fulfilled from the data buffer at faster speeds, rather than
requiring access to the tape.
Chapter 1. Introduction 23
Page 48
Offboard data string searching
The TS1120 and later tape drives can search the data content of host server
records for string matches. The function is called offboard data string
searching because the data search workload can be performed offboard
from the host. Each drive performs a search at its own respective
maximum data rate. This greatly reduces the amount of data transfer and
host search times.
Encryption
All TS1130 and later tape drives are encryption capable, which means they
can convert data into a cipher that ensures data security. With IBM feature
code 9592 or 5592, TS1120 tape drives are encryption capable as well. To
perform encryption, the drive must be encryption-enabled by your
selection of one of three methods of encryption management. A key is
required to encrypt and decrypt the data. How a key is generated,
maintained, controlled, and transmitted depends on the operating
environment where the TS1120 and later tape drives are installed. Some
data management applications are capable of performing key management.
For an alternative solution, IBM provides a key manager that works in
conjunction with the keystore of your choice to perform all necessary key
management tasks. There is no recovery for lost encryption keys.
For more information about encryption, refer to Chapter 8, “Tape
encryption overview,” on page 215. Also refer to the IBM Encryption Key
Manager and Tivoli Key Lifecycle Manager publications listed in the
Related information section of this document. To choose a method of
encryption management, see the section about setting a drive's method of
encryption in the IBM System Storage TS3500 Tape Library with ALMS
Operator Guide.
Firmware for each model of 3592 tape drive (TS1140, TS1130, TS1120, or J1A) only
works in that specific model.
The 3592 tape drive supports four types of the IBM 3592 Tape Cartridge. For more
information about the supported cartridges, see “Mixing media in drives” on page
37.

Supported tape cartridges
Note: Management and handling of media cartridges is a customer function and
responsibility.
In the TS3500 Tape Library, frames that are installed with Ultrium tape drives use
Ultrium tape cartridges. Frames that are installed with 3592 tape drives use 3592
tape cartridges. A frame cannot house both Ultrium tape drives and 3592 tape
drives. Similarly, in an HD library, Model S24 contains HD slots that house only
3592 tape cartridges and Model S54 contains HD slots that house only Ultrium
tape cartridges. However, in a library that includes both types of frames, you may
insert 3592 tape cartridges into the lower I/O station of a Model L53, L52, or L32
frame for transport (by the cartridge accessor) to a Model D23, D22, or S24 frame.
Similarly, you may insert Ultrium tape cartridges into the lower I/O station of a
Model L23 or L22 frame for transport (by the cartridge accessor) to a Model D53,
D52, D32, or S54 frame. (Note that in both of these scenarios, your library must
contain an I/O station that will accept the type of cartridge that is being inserted.)

Using TSLM for communication
This topic describes the IBM Tape System Library Manager (TSLM).
TSLM provides a resource management layer between applications such as Tivoli
Storage Manager (TSM) and the tape library hardware. Essentially, TSLM
decouples tape resources from applications, which simplifies both the aggregation
and the sharing of tape resources.
TSLM provides the following benefits:
v Consolidated, mainframe-class media management services
v Centralized repository, access control and administration
v Management beyond physical library boundaries
– Access multiple TS3500 Tape Libraries as a single library image
– TS3500 Tape Libraries can be separate (at SAN distances) or connected in a
shuttle complex
v Dynamic sharing of resources across heterogeneous application boundaries
v Security features to permit or prevent application access to tapes
– Helps to enable common scratch pool and private pools for every application
– Ensures secure usage and visibility
v Policy-based drive and cartridge allocation
v Policy-based media-lifecycle management
v 3494 Emulation

Attachment interfaces
This section describes the types of interfaces that are available with the TS3500
Tape Library.
The TS3500 Tape Library supports the following attachment interfaces.
The SCSI Medium Changer Device, which supports:
Parallel SCSI interface
Fibre Channel interface
The Ethernet 10/100 interface, and the following protocols:
Simple Network Management Protocol (SNMP)
Hyper Text Transfer Protocol (HTTP)
Models L32 and D32 support Ultrium 1 and Ultrium 2 tape drives
with parallel SCSI low voltage differential (LVD) and high voltage
differential (HVD) interfaces.
The library supports Ultrium tape drives and 3592 tape drives with
a Fibre Channel interface.
SNMP traps are supported for drive and library events. SNMP
management query functionality is supported by using a standard
Management Information Block (MIB).
An embedded web server provides a web user interface for library
management and query capabilities. Except for certain service
capabilities, most of the operator panel functionality is provided on
the web user interface.
The TS3500 Tape Library supports the Ethernet 10/100 interface in auto negotiation
or fixed modes of 10 Mb/s and 100 Mb/s, and by using half or full duplex.
®
The library cannot be directly connected to a System z
with a Fibre Connection (FICON) or Enterprise System Connection (ESCON)
interface. Instead, the System z server must connect to the TS3500 Tape Library
through one of the following configurations:
v Through a 3953 Tape System and a Tape Control Unit (a TS1120 tape controller,
a 3592 J70, a 3494 VTS Model B10, a 3494 VTS Model B20, or a TS7700
Virtualization Engine Model TS7740), then to the TS3500 Tape Library
v Through a TS7700 Virtualization Engine Model TS7740 with integrated library
manager (code level 8.5.0.x and higher), then to the TS3500 Tape Library with
frame model L23 or D23 equipped with 4 Gb Fibre Channel switches (feature
code 4872 or 4873) or 8 Gb Fibre Channel switches (two of feature code 4875 or
4877)
Note: In order to support 8 Gb Fibre Channel switches, the TS7740 must be at
code level 8.20.0.x or higher.

and scalability of Ethernet and Token Ring). The technology offers a transport
mechanism for delivering commands, and provides high performance by allowing
processing to be done in the hardware.
You can establish Fibre Channel connections between Fibre Channel ports that
reside in the TS3500 Tape Library, one or more servers, and the network
interconnecting them. The network can consist of such elements as switches, hubs,
bridges, and repeaters used in the interconnection.
Small Computer System Interface
This section sets forth the conditions that apply to drives in the TS3500 Tape
Library that use a Small Computer System Interface (SCSI) interface.
The TS3500 Tape Library operates as a set of SCSI-3 devices. For drives that use a
SCSI interface, the following conditions apply:
v The Ultrium 2 tape drive attaches to a server through a Low Voltage Differential
(LVD) Ultra160 SCSI interface or a High Voltage Differential (HVD) Ultra SCSI
interface
v The Ultrium 1 tape drive attaches to a server through an LVD Ultra2 SCSI
interface or an HVD Ultra SCSI interface
Each SCSI drive canister uses shielded, VHDCI, 68-pin connectors and can attach
directly to a 2-byte-wide SCSI cable.
Note: The earlier version of the SCSI drive used HD68 connectors and was
packaged on a tray (sled). While drive trays are still supported, they can no longer
be ordered. For information about the replacement design, contact your IBM
representative.
Chapter 1. Introduction 31
Page 56
Any combination of up to two initiators (servers) and up to four targets (devices)
is allowed on a single SCSI bus if the following conditions are met:
v The SCSI bus is terminated properly at each end
v Cable restrictions are followed according to SCSI-3 standards
Under the SCSI-3 protocol, this type of attachment allows cable lengths of up to 25
m (81 ft) with the appropriate cable and terminator for HVD devices and up to 12
m (39 ft) for LVD devices.
For more information about the SCSI interface, see the IBM System Storage TS3500
Tape Library SCSI Reference.
FICON and ESCON interfaces
This section describes the FICON and ESCON interfaces used to attach the TS3500
Tape Library to the System z server.
The TS3500 Tape Library does not provide native attachment to Fibre Connection
(FICON) or Enterprise System Connection (ESCON) interfaces. Instead, the TS3500
Tape Library attaches to the IBM System z server (mainframe host) through one of
the following configurations:
v Through a 3953 Tape System (3953 F05 Frame and 3953 L05 Library Manager),
which allows attachment of the TS3500 Tape Library with 3592 tape drives (not
LTO Ultrium tape drives) to the IBM System z server (mainframe host). The
System z servers then attach through a FICON or ESCON interface to one of the
following FICON/ESCON-enabled components:
– IBM System Storage TS1120 Tape Controller Model C06 (3592 C06)
– IBM TotalStorage 3592 Tape Controller Model J70 (3592 J70)
– IBM TotalStorage 3494 Virtual Tape Server Model B10 (3494 B10)
– IBM TotalStorage 3494 Virtual Tape Server Model B20 (3494 B20)
– IBM Virtualization Engine TS7740 (code level 8.4.1.x and earlier)
v Through an IBM Virtualization Engine TS7740 with integrated library manager
(code level 8.5.0.x and later), which allows attachment of the TS3500 Tape
Library with 3592 tape drives (not LTO Ultrium tape drives) to the IBM System
z server (mainframe host).
Note: This configuration requires that the TS3500 Tape Library includes an L23
or D23 frame that is equipped with 4 Gb Fibre Channel switches (feature code
4872 or 4873) or 8 Gb Fibre Channel switches (two of feature code 4875 or 4877).
In order to use the 8 Gb Fibre Channel switches, the TS7740 must be at code
level 8.20.0.x or later.
|
|
|

v Through a 3592-C07 Tape Controller with integrated library manager, which
allows attachment of the TS3500 Tape Library with 3592 tape drives (not LTO
Ultrium tape drives) to the IBM System z server (mainframe host).
Note: This configuration requires that the TS3500 Tape Library includes an L23
or D23 frame that is equipped with 8 Gb Fibre Channel switches (feature code
4875 or 4877).
In each configuration, the FICON/ESCON-enabled products include attachment to
a system console. It is recommended that the TS3500 Tape Library also be
connected to a system console. This connection reduces the number of analog
phone lines needed for remote support and improves collaboration between the
systems in resolving hardware problems.

Page 57
The library needs a minimum of two Ethernet ports: one attached to your network
for use by the storage administrator and one attached to the private master console
network for remote support.
Note: In the past, a library only had a single Ethernet port. To ensure a separate
Ethernet connection from the library to the system console, at least one additional
Model D22, D32, or D52 frame was required, with a frame control assembly
(feature code 1452 or 1453) that contained a medium changer card pack (MCP)
with an Ethernet connection (feature code 1660). However, with the design and
inclusion of the enhanced frame control assembly in Models L23, D23, L53, and
D53, and the enhanced node card upgrade (feature code 1700 or 1701) for Models
L22, D22, L52, D52, L32, and D32, each frame now contains a medium changer
assembly (MCA) with two Ethernet ports. This eliminates the need for an
additional Model D22, D32, or D52 frame.
The TS3500 Tape Library feature code 2715 (TS3000 Attachment) provides an
Ethernet cable for the library connection to the system console.
When a FICON/ESCON-enabled product attaches to a TS3500 Tape Library, the
following functionality must be enabled on the tape library to ensure proper
operation:
v Advanced Library Management System (ALMS)
v Cartridge assignment policy with All Other VOLSERs assigned to a specific
logical library
Note: Insert Notification is no longer required and is not recommended.

Mixing drives in a logical library
This section contains information about drives that are compatible in a logical
library of the TS3500 Tape Library.
Note: If you plan to use encryption, also refer to “Configuration prerequisites for
encryption” on page 219.
The TS3500 Tape Library supports a mixture of Ultrium drive types in a logical
library, but it does not support a mixture of Ultrium and 3592 tape drives in a
logical library. Some independent software vendors (ISVs) support mixed drive
types within logical libraries; others do not. Some ISVs that support mixed drive
types do so with restrictions. For details, contact your ISV.
For situations where the ISV support does not exist or does not meet your
requirements, the TS3500 Tape Library provides another option to protect your
investment by partitioning the tape drives into separate logical libraries. You can
customize the partition to any number of slots by using menus.
Figure 10 on page 36 shows examples of methods for mixing Ultrium drive types
in a logical library.

Multi-Path Architecture
This topic explains Multi-Path Architecture feature of the TS3500 Tape Library,
which allows Open Systems applications to share the library's robotics.
The TS3500 Tape Library features the storage area network (SAN)-ready Multi-Path
Architecture, which allows homogeneous or heterogeneous Open Systems
applications to share the library's robotics without middleware or a dedicated
server (host) acting as a library manager. The SAN-ready Multi-Path Architecture
makes sharing possible by letting you partition the library's storage slots and tape
drives into logical libraries. Servers can then run separate applications for each
logical library. This partitioning capability extends the potential centralization of
storage that the SAN enables. Partitioning also provides investment protection for
Ultrium 1 and Ultrium 2 tape drives if your application does not support the
|
mixing of Ultrium 1, Ultrium 2, Ultrium 3, Ultrium 4, Ultrium 5, and Ultrium 6
tape drives and media in the same logical library. The Multi-Path Architecture is
compliant with the following attachment interfaces:
v Small computer system interface (SCSI)
v Fibre channel
The Multi-Path Architecture of the TS3500 Tape Library is designed to provide the
capability to share the library robotics. This is accomplished by partitioning the
library into as many as 192 logical libraries (up to the number of drives installed),
and providing each logical library its own separate and distinct drive(s), storage
slots, and control paths. Input/output (I/O) slots are shared on a first come, first
serve basis. This type of partitioning is designed to allow heterogeneous
applications to share the library robotics independent of each other. Cartridges
under library control are not shared between logical libraries, nor are they allowed
to be moved between logical libraries. An example of heterogeneous sharing is a
Microsoft Windows 2003 application using the drive and storage slots of one
logical library, while a UNIX application uses the drive and slots of another logical
library. Logical libraries can also be used for separating Ultrium 2 tape dives and
cartridges from Ultrium 4 tape drives and cartridges, or 3592 tape drives and
cartridges, for applications that do not support mixing the drives in the same
logical library.
Whether partitioned or not, the TS3500 Tape Library is certified for SAN solutions
(such as LAN-free backup).
The Multi-Path Architecture also lets you configure additional control paths for
any one logical library. A control path is a logical path into the library through
which a server sends standard SCSI Medium Changer commands to control the
logical library. Additional control paths reduce the possibility of failure in one
control path causing the entire library to be unavailable. Use of the control path
failover feature further reduces that possibility.
40 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 65
Library sharing
This section describes ways that you can configure the TS3500 Tape Library into
one or more logical libraries that can be shared by multiple applications.
The default configuration for the TS3500 Tape Library allows a single application
to operate the library through a single control path. Often, however, it is
advantageous to be able to share a single library between heterogeneous or
homogeneous applications. Some applications (and some servers) do not allow for
sharing a library between systems. With the TS3500 Tape Library, however, you can
create configurations that enable the library to process commands from multiple
heterogeneous applications (such as an IBM pSeries
®
application and a Windows
application) and multiple homogeneous applications (for example, the same
application run by several pSeries servers).
From the library's web interface or operator panel, you can perform the following
actions:
v Configure the library so that it is partitioned into separate logical libraries that
independently communicate with separate applications through separate control
paths. This configuration (see example 1 in Figure 11 on page 42) requires no
special capabilities from the server or application.
v Configure any single logical library (including the entire physical library) so that
it is shared by two or more servers that are running the same application.
Depending on the capabilities of the server and application, there are several
ways to set up this type of configuration. Three typical ways include:
– Configuring one server (mainframe host) to communicate with the library
through a single control path; all other servers send requests to that server
through a network (see example 2 in Figure 11 on page 42). This
configuration is used by Tivoli
®
Storage Manager (TSM).
– Configuring all of the servers to communicate with the library through a
single, common control path (see example 3 in Figure 11 on page 42). This
configuration is used in high-availability environments such as
High-Availability Cluster Multi-Processing (HACMP
™
) from IBM and Systems
Management Server and Clustered Server Environments from Microsoft.
Multi-initiator configurations are only supported by certain adapters and
independent software vendors (ISVs). Check with your ISV.
– Configuring a single logical library to communicate with multiple servers
through multiple control paths. This configuration (see example 4 in
Figure 11 on page 42) requires that you add control paths. It is used by
Backup, Recovery, and Media Services.
Your library configuration is not limited to the examples shown in Figure 11 on
page 42. Many configurations are possible, and you can design them according to
your business needs.

Using multiple logical libraries
To maximize your investment, you can use multiple logical libraries to share the
physical TS3500 Tape Library between applications or to support mixed drive
types for any application. The sections that follow give guidelines for both
processes.
You can create multiple logical libraries by partitioning the physical library's
storage slots and tape drives into two or more logical libraries. Each logical library
consists of:
v Tape drives
v Storage slots
v Input/Output (I/O) slots
v Cartridge accessor
Each logical library has its own control path. A control path is a logical path into
the library through which a server sends standard SCSI Medium Changer
commands to control the logical library. For frames that contain Ultrium tape
drives and frames that contain 3592 tape drives, each logical library control path is
available to servers through logical unit number (LUN) 1 of the first drive that is
defined within that logical library. A LUN is a number used by a server to identify
a drive.
In a TS3500 Tape Library with ALMS, a logical library can share the tape drives
and storage slots of another logical library. The library also shares the I/O slots
and the cartridge accessor on a first-come, first-served basis. However, a logical
library cannot include both LTO and 3592 elements. That is, you must configure
LTO and 3592 elements (drives, storage slots, I/O slots, and grippers) into separate
logical libraries.
A frame that uses Ultrium tape drives can be partitioned into up to 12 logical
libraries. A frame that uses 3592 tape drives can also be partitioned into up to 12
logical libraries.
Note: When naming logical libraries, developing an enterprise-wide library
naming convention leads to easier management of the libraries. See the appropriate
section in the IBM System Storage TS3500 Tape Library with ALMS Operator Guide for
more information.
Certain configuration prerequisites exist when using encryption in your library. For
an overview of these rules, see “Configuration prerequisites for encryption” on
page 219.
To create or change the configurations for your TS3500 Tape Library, see the IBM
System Storage TS3500 Tape Library with ALMS Operator Guide.
With automatic cleaning, any appropriate cleaning cartridge can be used to clean a
drive in any configured logical library, even if the cartridge resides in a different
logical library.
The following sections describe two uses for multiple logical libraries.
Using multiple logical libraries for library sharing
Multiple logical libraries are an effective way for the TS3500 Tape Library to
simultaneously back up and restore data from heterogeneous applications. For
example, you can partition the library so that it processes commands from
Chapter 1. Introduction 43
Page 68
Application 1 (about Department A) in Logical Library 1, commands from
Application 2 (about Department B) in Logical Library 2, and commands from
Application 3 (about Department C) in Logical Library 3. In this configuration, the
storage slots and drives in each logical library are dedicated to that library and are
not shared among other libraries. Commands issued by the applications travel to
the library through three unique control paths. Thus, the data processing for
Department A is confined to the storage slots and drives in Logical Library 1,
processing for Department B is confined to the storage slots and drives in Logical
Library 2, and so forth.
Using multiple logical libraries for mixed drive types
For applications that do not support mixed drive types and media in the same
logical library, the TS3500 Tape Library can use partitioning and multiple logical
libraries to keep them separate. For example, you can partition Ultrium 5, Ultrium
4, Ultrium 3, Ultrium 2, and Ultrium 1 tape drives and their media into multiple
and separate logical libraries.
Using multiple control paths
With the TS3500 Tape Library, in addition to creating multiple logical libraries, you
can also configure any logical library to have more than one control path. When
you configure additional control paths, additional library sharing configurations
and availability options are made possible. Access to the logical library is on a
first-come, first-served basis and each control path for a logical library can accept
commands while the library is in use by another control path.
Note: Microsoft Windows 2000 Removable Storage Manager (RSM) does not
support multiple control paths within a logical library. IBM recommends that you
disable RSM to use this feature.
To add or remove additional control paths, see the IBM System Storage TS3500 Tape
Library with ALMS Operator Guide.
The sections that follow describe two potential uses for multiple control paths.
Using multiple control paths for IBM i attachment
The use of control paths for IBM Power Systems™running IBM i and the System
i®, iSeries®, and AS/400®servers is unique. In general, every IBM i, System i, and
iSeries input/output processor (IOP)-based adapter must “see” the control path
that is associated with the drives to which it is connected. The following list
presents possible scenarios:
v For a high voltage differential (HVD) small computer system interface (SCSI)
Ultrium 1 tape drive, IBM supports single drive configurations so that every
HVD Ultrium 1 tape drive must have a control path when connected to the
System i or iSeries server.
v For HVD and low voltage differential (LVD) SCSI Ultrium 2 tape drives, the
System i or iSeries server supports multiple drives that are connected per the
IOP-based adapter. One of the drives must have a control path.
®
v For the Fibre Channel-attached drives, OS/400
per IOP-based adapter and every drive requires a control path.
v For an OS/400 V5R2 and later Fibre Channel connection, the IOP-based adapter
supports multiple drives per adapter, so that only one control path for the group
of drives is required.
V5R1 supports only one drive
44 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 69
v For V6R1 and Power 6 hardware using the IOP-less (Smart IOA), the adapter
has two Fibre Channel ports and supports multiple devices per port. At least
one control path is required per IOA and per set of drives within a library
partition.
v For V7R1 and Power 6 or Power 7 hardware using the IOP-less (Smart IOA), the
adapter has two Fibre Channel ports and supports multiple devices per port. At
least one control path is required per IOA port and per set of drives within a
library partition.
Using multiple control paths for control path failover
The TS3500 Tape Library offers an optional control path failover feature that
enables the host device driver to resend the command to an alternate control path
for the same logical library.
Advanced Library Management System
This section explains the Advanced Library Management System (ALMS), which
virtualizes the locations of cartridges in the TS3500 Tape Library.
ALMS is an extension of IBM's patented Multi-Path Architecture. With ALMS, the
TS3500 Tape Library is the industry's first standards-based tape library to virtualize
the locations of cartridges (called SCSI element addresses) while maintaining native
SAN attachment for the tape drives. ALMS enables logical libraries to consist of
unique drives and ranges of volume serial (VOLSER) numbers, instead of fixed
locations.
When you enable ALMS with its license key, you can assign tape drives to any
logical library by using the Tape Library Specialist Web interface. Logical libraries
can also be added, deleted, or easily changed without disruption. Storage capacity
can be changed without impact to host applications.
ALMS offers dynamic management of cartridges, cartridge storage slots, tape
drives, and logical libraries. It enables the TS3500 Tape Library to achieve
unprecedented levels of integration for functionality through dynamic partitioning,
storage slot pooling, and flexible drive assignment. ALMS eliminates downtime
when you add Capacity On Demand (CoD) or High Density Capacity on Demand
(HD CoD) storage, add or remove logical libraries, or change logical library storage
allocation. ALMS also reduces downtime when you add expansion frames, add or
remove tape drives, or change logical drive allocation.
The capabilities of ALMS include:
v Dynamic partitioning (storage slot pooling and flexible drive assignment)
v The transparent ability to add or remove storage capacity to any host application
v The ability to configure drives or to configure Model L22, L23, L32, L52, or L53
storage capacity without taking the library offline
v Virtual I/O slots to automatically manage the movement of cartridges between
I/O slots and storage slots
If you purchase an entry-capacity or intermediate-capacity library, you can
purchase the new Entry ALMS or Intermediate ALMS at a price lower than the
Full ALMS. For more information, contact your IBM marketing representative.
The sections that follow describe the capabilities of ALMS.
Chapter 1. Introduction 45
Page 70
Dynamic partitioning
The following topics explain dynamic partitioning. Dynamic partitioning in the
TS3500 Tape Library is comprised of storage slot pooling and flexible drive
assignment.
Storage slot pooling
When enabled in the TS3500 Tape Library, the Advanced Library Management
System (ALMS) allows logical libraries to be added or deleted without disrupting
operation. All storage slots are pooled (available on a first-come, first-served basis)
to each logical library based on cartridge insert operations. They are a shared
resource such that changes to the capacity allocation for each logical library can
occur without downtime or administrator involvement. The minimum logical
library simply has a name and can be thought of as a file folder that has no
contents. Drives can be placed in the file folder by using the Drive Assignment
screen of the Tape Library Specialist Web interface. Cartridges can also be placed in
the file folder, based on their volume serial (VOLSER) numbers and by using one
of the following methods (in priority order):
v Migration of static partitioning to dynamic partitioning (requires Web
enablement of ALMS)
v Cartridge assignment policy (automatic at the time of insertion)
v Software application move from the I/O station (based on the source application
that issued the command)
v Manual assignment by an operator using the Tape Library Specialist Web
interface
For information about migrating to dynamic partitioning and manually assigning
cartridges to a logical library, refer to the IBM System Storage TS3500 Tape Library
with ALMS Operator Guide.
The primary and backup copies of VOLSER assignment and physical location of
cartridges are stored in non-volatile random access memory (NVRAM).
Flexible drive assignment
After you enable the Advanced Library Management System (ALMS) in the TS3500
Tape Library, you can assign drives to a logical library by using the Drive
Assignment screen of the Tape Library Specialist Web interface. You can assign a
drive to be shared by multiple logical libraries (for example, a drive used for a
once-a-month job or as a temporary replacement for a failed drive). Thus, each
logical library can consist of dedicated drives and shared drives. Each logical
library maps a drive element address to the locations of both dedicated and shared
drives. This allows multiple applications to be pre-configured to quickly use a
shared drive in the future. After you pre-configure the applications for future drive
usage, you must take each shared drive offline at all but one of the applications
that have access to it. Otherwise, an application may attempt to use a drive that is
in use by another application. This may cause failed backup jobs. Also, most
applications consider the symptoms of a drive already in use to be an error that is
reported as such.
The Drive Assignment Web screen supports the following capabilities which are
not disruptive to other logical libraries:
v Assign the drive
v Remove the drive assignment
v Reassign the drive
46 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 71
When a cartridge is mounted in a shared drive, the library only accepts a demount
command that is requested by the source logical library. Any demount command
that is requested by another logical library is rejected.
Transparent addition or removal of storage capacity
With the Advanced Library Management System (ALMS) enabled in the TS3500
Tape Library, you can change the total logical library capacity (quantity of
accessible storage slots). The change is transparent to each host application because
the value in the Maximum Number of Cartridges field in the Tape Library Specialist
Web interface is not impacted by changes to the quantity of storage slots. The
additional storage slots are simply new candidates for cartridges to be moved to
upon insertion. To change the cartridge capacity of a logical library, refer to the
IBM System Storage TS3500 Tape Library with ALMS Operator Guide and see the
section about changing the maximum allowable quantity of cartridges in a logical
library.
Configuration of storage capacity without disruption
With the Advanced Library Management System (ALMS), no downtime is required
when you enable Intermediate Capacity On Demand or Full Capacity On Demand
for Models L22, L23, L52, and L53 or High Density Capacity on Demand for
Models S24 and S54 of the TS3500 Tape Library.
Virtual I/O slots
This topic describes the virtual input/output (I/O) slots feature and its benefits in
a library with the Advanced Library Management System (ALMS).
|
|
When ALMS is enabled in a TS3500 Tape Library, virtual I/O slots are enabled by
default so that the library automatically queues all cartridge moves between the
I/O station and the storage slots. This makes the process of adding and removing
cartridges easier and faster.
The TS3500 Tape Library has I/O stations with I/O slots that allow you to import
and export up to 224 cartridges at any given time. The I/O slots are also known as
import/export elements (IEEs). Virtual I/O slots increase the quantity of available
I/O slots by allowing storage slots to appear to the host as I/O slots. These storage
slots are also called virtual import/export elements (VIEEs). With virtual I/O slots,
the library automatically moves cartridges from the I/O stations to the storage
slots. In this way, the library enhances its import and export capabilities.
The goal of virtual I/O slots is to reduce the dependencies between the system
administrator and library operator so that each performs their import and export
tasks without needing the other to perform any actions:
v In a typical import scenario without virtual I/O slots, a library operator is
needed to stand at the physical library and fill the I/O station with cartridges; a
system administrator is needed to cause the applications to send commands for
moving cartridges out of the I/O station and into library storage slots. After the
operator fills the I/O station with cartridges, he must wait for the I/O station to
be cleared before he is able to insert additional cartridges, which means he is
waiting on the system administrator to clear the I/O station of each set of
inserted cartridges. If the library is enabled with virtual I/O slots, the operator
can continuously insert cartridges into the I/O station and the administrator
does not need to issue commands to move each new set of inserted cartridges.
Chapter 1. Introduction 47
Page 72
Instead, the library automatically moves the cartridges and places them into
virtual I/O slots until they are ready to be processed later as one composite set
of inserted cartridges.
v In a typical export scenario without virtual I/O slots, the system administrator
may need to export a large number of cartridges from the library. However, after
the I/O station is filled, he must wait for the operator to physically remove
cartridges from the entire I/O station before he can issue another export
command. This operation can be inconvenient. If the library is enabled with
virtual I/O slots, the administrator does not have to wait to issue all export
commands (up to 255 export commands can be issued at the same time for each
logical library) and the operator can remove cartridges from the I/O stations as
soon as the accessor automatically moves them from the storage slots.
With virtual I/O slots enabled, the library has various mechanisms for selecting
the best storage slot location for each inserted cartridge, as well as the best
accessor and I/O station for each ejected cartridge. These mechanisms vary
depending on the configuration of your library.
For ejects with virtual I/O slots enabled and I/O stations in both preferred zones
of a dual accessor library, the library selects the accessor and I/O stations that are
in the same preferred zone as the physical slot of the cartridge to be ejected, but
will maintain First In, First Out (FIFO) order for each zone. For ejects with virtual
I/O slots enabled and I/O stations in only one zone of a dual accessor library, the
library selects the accessor in that preferred zone and maintains FIFO order.
For more information, see “Cartridge assignment policy” and “Insert notification
setting” on page 49.
For detailed information about import and export performance in libraries with
virtual I/O slots enabled, refer to “Import and export performance with virtual
I/O slots” on page 86.
Cartridge assignment policy
This section describes the cartridge assignment policy for assigning cartridges to
specific logical libraries.
You identify a cartridge by affixing a label to it that bears a volume serial
(VOLSER) number. The cartridge assignment policy allows you to specify one or
more ranges of VOLSERs for logical libraries. For example, you can create a
cartridge assignment policy of 36 cartridge VOLSERs that range from 000764 to
000800 for a specific logical library. Note that VOLSERs in ranges do not include
the media-type indicator, such as L2, L3, JA, and so forth.
When you insert a cartridge into the library and its VOLSER is within a range, the
cartridge assignment policy assigns the cartridge to its logical library. The cartridge
must be of the same media type as that logical library. For example, if you create
for Logical Library 1 (a library of Ultrium drives) a cartridge assignment policy of
VOLSERs that range from ABC000 to ABC999 then you insert a cartridge with
VOLSER ABC123, the library recognizes that VOLSER as belonging to the range
and assigns it to Logical Library 1, provided that the cartridge is an Ultrium tape
cartridge (and not a different media type, such as a 3592 tape cartridge).
When an unassigned cartridge is present in the I/O station, the library reads its
VOLSER label and automatically assigns it to the logical library that is specified in
the range of VOLSERs which was previously selected by the system administrator
48 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 73
when creating a cartridge assignment policy. Similarly, when ALMS is enabled, if
you open and close the library's front door the library automatically performs an
inventory. If the library detects a newly inserted, unassigned cartridge, it assigns
the cartridge to the logical library of the VOLSER range that was previously
selected by the system administrator when creating a cartridge assignment policy.
A cartridge assignment policy can also be created for All Other VOLSERs. This
represents all VOLSERs not covered by specific ranges in the cartridge assignment
policy. If you do not want these cartridges to be assigned to an active logical
library, then you can create a new drive-less logical library and have the All Other
VOLSERs automatically assigned to that logical library. In this way, the drive-less
logical library becomes a safe media vault. Note that a drive-less logical library
consumes no additional resources in a TS3500 Tape Library with ALMS.
Subsequently, these All Other VOLSERs can be manually assigned to a different
logical library using the Tape Library Specialist Web interface or the TS3500 Tape
Library Command Line Interface (CLI).
If there is no cartridge assignment policy assigned for All Other VOLSERs,
unassigned cartridges can be assigned by one of the following methods:
v If the unassigned cartridge is in the I/O station and the Insert Notification
setting is disabled, the cartridge is automatically assigned on a first-come,
first-served basis
v If the unassigned cartridge is in the I/O station and the Insert Notification
setting is enabled, you can assign the cartridge to a logical library by using the
Settings and Insert Notification selections from the library's operator panel
v Use the cartridge assignment policy to create a new VOLSER range and then
perform an inventory
v Use the Tape Library Specialist Web interface
v Use the TS3500 Tape Library CLI
Within a physical library, the maximum quantity of ranges that can be created by
the cartridge policy assignment is 300.
For more information, see “Insert notification setting” and “TS3500 Tape Library
Command Line Interface” on page 57. For information about creating a new
VOLSER range, performing an inventory, or assigning cartridges to a logical
library, see the appropriate sections in the IBM System Storage TS3500 Tape Library
with ALMS Operator Guide.
Insert notification setting
This section describes insert notification. This is an optional setting that enables the
TS3500 Tape Library to monitor the I/O station for new media that does not have
a logical library assignment.
Note: Insert notification is no longer recommended and is not supported in any
library that includes an HD frame. In HD libraries, insert notification is
automatically disabled. When Insert Notification is disabled, TS7700 Virtualization
Engine and 3953 L05 Library Manager customers should assign All Other Volsers
to a specific logical library. Refer to “Cartridge assignment policy” on page 48 for
more information.
An insert notification event can be caused if you open the I/O station door and
perform one of the following actions:
Chapter 1. Introduction 49
Page 74
v Place a cartridge into an empty I/O slot
v Move a cartridge from one I/O slot to another
If you enable the insert notification setting, when new media is detected in the I/O
station the operator panel displays a message that asks you to select a logical
library. Any unassigned cartridges in the I/O station are then assigned to the
logical library that you select (and all other logical libraries will not be able to
access the cartridges). If you do not select a logical library within 60 seconds or if
you select the BACK button, the library makes the cartridges unassigned and the
operator panel returns to the Activity Screen. You can later assign the unassigned
cartridges by using the IBM System Storage Tape Library Specialist Web interface
or the TS3500 Tape Library Command Line Interface.
For more information, see the sections about enabling or disabling the insert
notification setting and assigning cartridges to a logical library in the IBM System
Storage TS3500 Tape Library with ALMS Operator Guide.
Power structure of the TS3500 Tape Library
This section introduces the two power structures that are offered by the TS3500
Tape Library.
Depending on the frames that you have, the library offers two power structures:
v For Models L22, D22, L32, D32, L52, and D52, the library offers the frame control
assembly power structure, with the option of ordering dual AC line cords for
redundancy.
v For Models L23, D23, L53, and D53, the library offers the enhanced frame control
assembly power structure, which combines drive power, library power, and
standard dual AC line cord capabilities.
The two power structures are compatible among frames in the same library.
Frame control assembly and dual ac power
This section describes the frame control assembly (FCA) power structure and the
optional dual ac power feature of the TS3500 Tape Library. This power structure
and feature apply to Models L22, D22, L32, D32, L52, and D52.
The frame control assembly power structure is designed so that each Ultrium tape
drive and 3592 tape drive is paired with an associated power supply. Adjacent
power supplies are cabled together such that redundant power becomes a standard
function. Each pairing is packaged side by side on a shelf in a frame. Drives are
housed in removable canisters and power supplies are housed in fixed trays. The
design enables a drive with a failed power supply to continue operating by using
power from the adjacent power supply.
The library's optional dual ac power feature further enhances library availability by
making another power source available in case of planned or unplanned power
grid outages. The feature provides a power switch that connects to two
independent ac power cords which connect to two independent branch power
feeds. The power cords support 110 V ac or 220 V ac. The switch monitors the ac
line voltage from the feed it uses and automatically connects to the alternate power
feed if the incoming voltage is lost. Dual ac power is available when you order
feature code 1901.
50 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 75
Enhanced frame control assembly
The enhanced frame control assembly is a power structure that combines drive
power, library power, and dual ac line cord capabilities. The assembly includes
only two power supplies, dual ac line cords, and a Medium Changer Assembly
(MCA) unit.
The enhanced frame control assembly comes standard with Models L23 and L53,
and can be ordered as a feature code for Models D23 and D53. For two or more
frames that are properly configured, the assembly is constructed such that failure
or repair of a single, particular part does not cause the entire system to fail or
require scheduled downtime for maintenance. For example, the replacement of any
single, failed power supply can be accomplished without affecting the operation of
the library. The two redundant power supplies are fed directly by independent,
dual ac line cords that support only 220 V ac (110 V ac is not supported). The dual
ac line cords come standard on Models L23, D23, L53, and D53, and do not need
to be ordered as an additional feature code.
If dual ac line cords are not desired, both power supplies can be fed by a single
customer outlet by using feature code 1909 (Single Power Source Bifurcated Cable),
however, feature code 1909 cannot be used if feature code 1950 (Power Distribution
Unit) is installed in the same frame.
The enhanced frame control assembly is compatible with the following model
conversions, which must be performed by an IBM Service Representative:
v Model L22 to L23
v Model D22 to D23
v Model L52 to L53
v Model D52 to D53
v Model L23 to L53
v Model D23 to D53
v Model L53 to L23
v Model D53 to D23
Models L23 and D23 equipped with feature code 4871 (TS7700 Backend Switches
mounting hardware) must also have feature code 1950 (Power Distribution Unit),
which enables dual ac power distribution to the Fibre Channel switches as well as
to the enhanced frame control assembly.
Control path failover, data path failover, and load balancing
This section discusses measures that the TS3500 Tape Library uses to control
library and data path failure, and to balance workload.
Command failures and time-outs are costly. You want your library to run smoothly
and efficiently. To ensure continued processing, libraries that are equipped with
Fibre Channel Ultrium and 3592 tape drives offer path failover and load balancing
capabilities that enable the IBM device driver to resend a command to an alternate
path. The alternate path can include another host bus adapter (HBA), Storage Area
Network (SAN), or library control path drive. The device driver initiates error
recovery and continues the operation on the alternate path without interrupting
the application. Path failover and load balancing are built-in features that are
enabled by using a purchased license key.
Chapter 1. Introduction 51
Page 76
Two types of path failover capabilities exist: control path failover (CPF) and data path
failover (DPF). Control refers to the command set that controls the library (the SCSI
Medium Changer command set on LUN 1 of the tape drives). Data refers to the
command set that carries the customer data to and from the tape drives (the
SCSI-3 Stream Commands (SSC) device on LUN 0 of the tape drives). Path failover
means the same thing in both: that is, where there is redundancy in the path from
the application to the intended target (the library accessor or the drive mechanism,
respectively), the device driver transparently fails over to another path in response
to a break in the active path.
Both types of failover include host-side failover when configured with multiple
HBA ports into a switch, but CPF includes target-side failover through the control
paths that are enabled on more than one tape drive. DPF includes target-side
failover for the dual-ported tape drives that are supported by the TS3500 Tape
Library.
DPF includes load balancing of the HBAs because the channel is a data-intensive
path (the control path carries very little data, so load balancing is not an issue).
The dynamic load balancing support optimizes resources for devices that have
physical connections to multiple HBAs in the same machine. When an application
opens a device that has multiple HBA paths configured, the device driver
determines which path has the HBA with the lowest usage and assigns that path to
the application. When another application opens a different device with multiple
HBA paths, the device driver again determines the path with the lowest HBA
usage and assigns that path to the second application. The device driver updates
the usage on the HBA assigned to the application when the device is closed.
Dynamic load balancing uses all HBAs whenever possible and balances the load
between them to optimize the resources in the machine.
Both CPF and DPF require the use of the IBM device driver, and are supported
exclusively with products that bear the IBM logo on the operating systems
indicated in Table 13.
Table 13 summarizes the differences between CPF, DPF, and load balancing.

The path failover features can be ordered from the factory, or you may order them
as field upgrades. To order features, contact your IBM Sales Representative.
Note: The control path failover feature for Ultrium tape drives is activated by a
license key that you enter at the library operator panel. The data path failover
feature for Ultrium 1, Ultrium 2, and Ultrium 3 tape drives is activated by a license
key that you enter at the host. For Ultrium 4 and newer tape drives, license keys
do not need to be entered at the host when configuring Data Path Failover.
For more information about using these features, see the IBM Ultrium Device
Drivers Installation and User's Guide.
Expanded I/O capacity
This section describes the extra input/output (I/O) stations that you can order for
the TS3500 Tape Library.
To insert cartridges into and remove them from the TS3500 Tape Library (without
requiring a reinventory), the library comes with an I/O station located on the front
door of the base frame models. You can optionally order an additional I/O station
for installation on base frame models.
A base frame cannot combine both the 3592 tape drive and Ultrium tape drive.
However, in a library that mixes frame types, you may insert 3592 tape cartridges
into the lower I/O station of a Model L53, L52, or L32 frame for transport (by the
cartridge accessor) to a Model D23 or D22 frame (your library must contain an I/O
station that will accept 3592 tape cartridges). Similarly, you may insert LTO
Ultrium tape cartridges into the lower I/O station of a Model L23 or L22 frame for
transport (by the cartridge accessor) to a Model D53, D52, or D32 frame (again,
your library must contain an I/O station that will accept Ultrium tape cartridges).
The TS3500 Tape Library also supports an option for 64 additional I/O slots in a
newly purchased Model D23 or D53 frame. A D-frame with I/O installed includes
four independently accessible I/O stations. The D-frame I/O stations increase the
maximum I/O slot capacity from 32 to 224. There is a maximum of three D23 or
D53 I/O frames in a library. The D-frame I/O stations can double the maximum
insert/eject throughput in libraries with a dual accessor. These D23 and D53
Models are compatible with existing Models L22, L32, L52, D22, and D32.
Chapter 1. Introduction 53
Page 78
Note: The 64 additional I/O slots features (feature codes 1655 and 1656) are not
supported on libraries with mixed media. In order to use this feature, the library
must use all Ultrium media or all 3952 media, not a mixture of both.
Table 14 shows how I/O stations can be mixed among frames.
Table 14. Mixing I/O stations among frames of the TS3500 Tape Library

Notes:
1. The 3592 I/O station for Model L32 is included with feature code 1608.
2. For the 64 additional I/O slots option, feature code 1451 must be installed as a
prerequisite, then either feature code 1655 for LTO Ultrium media, or feature code 1656
for 3592 media. When expanding an installed library, feature codes 1655 and 1656
assume the D-frame is installed at the end of the library string ("end of the library
string" refers to the very last frame in a single accessor library or the last frame before
SBB in HA libraries). If the customer prefers the D-frame to be installed elsewhere in
the string, the Service Representative must obtain a "Services Contract" to uninstall
additional frames as necessary to accommodate the customer's request.
3. Mixed media is not allowed in libraries with D-frame I/O slots. All cartridges must be
either LTO Ultrium or 3592.
4. A maximum of three D-frames with I/O slots can be installed per library.

Increasing capacity
This section introduces information about capacity configurations for frames of the
TS3500 Tape Library.
Depending on whether you have the Capacity Expansion feature, Capacity On
Demand feature, or High Density Capacity on Demand feature installed in your
library, different capacity configurations exist for the frames.
The sections that follow describe each feature.
Capacity expansion feature for Model L32
The Capacity Expansion feature (feature code 1603) is a license key that lets you
enable the storage slots inside the front door of Model L32 of the TS3500 Tape
Library. With the Capacity Expansion feature installed, the library offers 140
additional slots for Ultrium tape cartridges in the Model L32 if the second I/O
station is not present and 88 additional slots if the second I/O station is present.
The Capacity Expansion feature is required when you add one or more expansion
frames to the base frame.
54 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 79
When you purchase your library, you may specify that the Capacity Expansion
feature be installed at the factory, or you may order the feature later and have your
IBM Service Representative install it. To order the Capacity Expansion feature,
contact your IBM Sales Representative.
To determine the quantity of LTO Ultrium tape cartridges and 3592 tape cartridges
that the library supports, see Chapter 7, “Frame capacity,” on page 211.
Intermediate, Full, and Capacity On Demand features for Models L22, L23, L52, and L53
In the TS3500 Tape Library, the initial (entry) capacity of a Model L22 or Model
L23 frame is enabled to use 58 cartridge slots for 3592 tape cartridges. If you add
the Intermediate Capacity or Full Capacity features, you can enable additional
storage elements in the Model L22 or Model L23 to increase the available capacity
to 117 cartridge slots, or from 199 to 260 cartridge slots (depending on the features
that you order).
The initial capacity of a Model L52 or Model L53 frame is enabled to use 64
cartridge slots for LTO Ultrium tape cartridges. If you add the Intermediate
Capacity or Full Capacity features, you can enable additional storage elements in
the Model L52 or Model L53 to increase the available capacity to 129 cartridge
slots, or from 219 to 287 cartridge slots (depending on the features that you order).
The Intermediate Capacity feature is available through an IBM plant site as feature
code 1641 and through the field as feature code 1643.
The Full Capacity feature is available through an IBM plant site as feature code
1642 and through the field as feature code 1644. This feature is required to add a
16-slot I/O station. The Intermediate Capacity feature is a prerequisite to the Full
Capacity feature. The Full Capacity feature is required when you add one or more
expansion frames to a base frame.
Capacity features that are available through the field are known as Capacity On
Demand.
To determine the quantity of LTO Ultrium tape cartridges and 3592 tape cartridges
that the library supports, see Chapter 7, “Frame capacity,” on page 211.
High Density Capacity On Demand
This section describes the High Density Capacity on Demand features for the
TS3500 Tape Library.
The HD Capacity on Demand feature codes provides a license key that let you
enable additional storage slots in HD frames.
In the TS3500 Tape Library, the physical capacity, or total storage slots, is
comprised of licensed and unlicensed capacity. When the number of assigned
cartridges within a library reaches the licensed capacity, additional inserted
cartridges are not assignable to a logical library until one of the following actions
occurs:
v A cartridge is removed
v A CoD feature is purchased
v Additional slots or frames are added to the library
Chapter 1. Introduction 55
Page 80
Web interface
The capacity utilization of the library can be monitored through the Tape Library
Web specialist.
The initial (base) capacity for Model S24 is 600 slots and for Model S54 is 660 slots.
Additional capacity for Models S24 and S54 can be purchased with the High
Density Capacity on Demand (HD CoD) features that provide a license key to
non-disruptively increase the licensed capacity. Unlike other Capacity on Demand
features, the HD CoD feature allows the additional licensed capacity to be used in
any HD frame in the library string.
Feature code 1645 adds 400 slots of capacity to Model S24. Feature code 1646 adds
660 slots of capacity to Model S54.
To determine the quantity of LTO Ultrium tape cartridges and 3592 tape cartridges
that the library supports, see Chapter 7, “Frame capacity,” on page 211.
This section gives basic information about the IBM System Storage Tape Library
Specialist, the Web interface for the TS3500 Tape Library.
The Tape Library Specialist Web interface enables operators and administrators of
the TS3500 Tape Library to manage storage devices from any location in an
enterprise. The Tape Library Specialist allows you to communicate directly with
your library and perform a full range of end user, operator, and administrator
tasks without being at the operator panel. The Web interface is included with
Models L22, L23, L52, and L53, and is available as feature code 1662 for Model
L32.
The Tape Library Specialist requires a Category 5 Ethernet cable (not supplied with
the tape library). It may be installed by you or your IBM Service Representative.
You can use the Tape Library Specialist Web interface to download the following
flat files, which contain information for analyzing the library, drives, Fibre Channel
ports, and the health of the cartridges. Information is available from Ultrium 2 and
newer Ultrium tape drives and from all 3592 tape drives.
v Library Statistics.csv - contains information about the maximum cartridge
residency, mount, and eject times, average cartridge residency, mount, and eject
times, and total cartridge inserts, mounts and ejects. The information is provided
for each hour of a 24-hour period and for each logical library. Note: To obtain
this log, your library must include Model L23 or L53.
v Drive Statistics.csv - contains information about each drive's last mount; only
installed drives are shown in the drive statistics log.
v Port Statistics.csv - contains Fibre Channel port information about the last
mount; only installed drives with Fibre Channel ports are shown in the port
statistics log.
v Mount History.csv - includes statistics about the last 100 cartridges that were
demounted in the library and information about the 3592 E05 (at firmware level
16E4 or later), Ultrium 4, and newer tape drives that is derived from the
customer-centric Statistical Analysis and Reporting System (ccSARS).
The TS3500 Tape Library downloads the files in comma-separated value (.csv)
format. You can use the data to identify storage area network (SAN), drive, or
media performance trends. The .csv file format can easily be imported into most
spreadsheet and database programs.

section about operating the library from the Web in the IBM System Storage TS3500
Tape Library with ALMS Operator Guide.
TS3500 Tape Library Command Line Interface
This topic describes the TS3500 Tape Library Command Line Interface (CLI)
program, which provides the ability to access TS3500 Tape Library functions
through a CLI.
In order to use the TS3500 Tape Library CLI, the following prerequisites apply:
v The TS3500 Tape Library must be at firmware level 8xxx (or higher).
v The Advanced Library Management System (ALMS) must be installed and
enabled.
v Secure Socket Layer (SSL) for the Web must be disabled.
The TS3500 Tape Library CLI, along with additional information including
supported actions and command parameters, can be found here:
http://www-01.ibm.com/support/docview.wss?uid=ssg1S4000854.
IBM Tape System Reporter
This section describes the IBM Tape System Reporter application and how it works
in supported environments.
The IBM Tape System Reporter application is a Java-based monitoring server with
an optional Windows-based graphical user interface (GUI) that allows you to
monitor and gather data for multiple libraries. You can generate general and
specific data reports for the multiple tape cartridges, tape drives, and frames that
you are monitoring.
The IBM Tape System Reporter application enables operators and administrators of
the TS3500 Tape Library to monitor and report on storage devices from any
location in an enterprise environment. This application communicates directly with
your library to collect and store pertinent data enabling you to generate and view
performance trends. The IBM Tape System Reporter application is bundled with
your Advanced Library Management System (ALMS) purchase.
Data is available from 3592 tape drives (models J1A, E05, E06, EU6, and E07) and
from LTO Ultrium 2 and newer Ultrium tape drives.
The ccSARS data is available from 3592 E05, Ultrium 4, and newer tape drives.
Notes:
1. Data is not collected for the LTO Ultrium 1 tape drive.
2. Use of the IBM Tape System Reporter application requires that you establish
database connectivity through firewalls and to any tape libraries that it is
monitoring.
The IBM Tape System Reporter application operates by collecting information from
the TS3500 Tape Library, aggregating the data in a database, and providing you the
ability to generate a report. You can generate a General SQL Query or custom
report on the utilization and performance of tape cartridges, tape drives, and the
tape library. The application can be installed by you or by IBM Lab Services.
Figure 12 on page 58 illustrates how the Tape System Reporter application collects
Chapter 1. Introduction 57
Page 82
information from the tape libraries, aggregates the data in a database, and provides
you with the opportunity to generate a general query or custom report.

This is particularly effective when workload balancing is a consideration.
For more information about the prerequisites for using the IBM Tape System
Reporter, installing and setting up the application, working with the Apache Derby,
DB2, or Oracle databases, and generating reports, refer to the IBM System Storage
TS3500 Tape Library with ALMS Tape System Reporter User's Guide (GA32-0589). You
can also find information about the IBM Tape System Reporter on the Web at
http://www-01.ibm.com/support/docview.wss?uid=ssg1S4000680.
Remote support
This section describes the types of remote support that the TS3500 Tape Library
and its drives use to detect and solve problems.
Optional remote support is available for the TS3500 Tape Library through its Call
Home capability. The Call Home feature uses a modem connection or a system
console to report failures that are detected by the library or a tape drive. Whenever
a failure is detected, Call Home sends detailed error information to IBM (home).
The IBM Service Representative can then prepare an action plan to handle the
problem before traveling to the library. The library may also periodically send
support information (such as configuration, library and drive code versions, and
error logs) to IBM.

The Call Home feature of the TS3500 Tape Library has three different, but related,
capabilities: Problem Call Home, Heartbeat Call Home, and Test Call Home. The
TS3500 Tape Library sends data files that may be helpful to Support Center
personnel for all three types of Call Home. These data files include library error
logs and configuration information, such as the Machine Reported Product Data
(MRPD) log. The MRPD file contains information about the machine (library),
including the number of frames and drives, the model and serial number of each
58 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 83
frame, the type and serial number of each drive, the code version of the library
and each drive, and any machine-detectable features such as additional I/O
stations, capacity expansion, and so forth. In the case of a Problem Call Home, the
library also sends any trace files that are related to the problem.
Problem Call Home
The TS3500 Tape Library or one of its drives detects a problem and the
library performs a Call Home operation to create a Problem Management
Record (PMR) in the IBM Remote Technical Assistance Information
Network (RETAIN). This is a single page of text data that enables the
Support Center or the Service Representative to access an action plan and a
list of parts (called field replaceable units or FRUs).
Heartbeat Call Home
The TS3500 Tape Library sends the Heartbeat Call Home on a scheduled
basis in order to ensure proper Call Home functionality. By default, the
Heartbeat Call Home is sent once per week, one hour after a power cycle,
and one hour after a code update is complete.
Test Call Home
When servicing the library, the Service Representative can issue a Test Call
Home operation to RETAIN from the library's operator panel. The library
allows the Service Representative to include drive dumps in the Test Call
Home for analysis, rather than collect dumps by using CETool and
transmitting them through an IBM messaging system. In this way, a drive
dump can be accessed by Support Center personnel through the Call
Home database.

Remote support through a modem
This section describes remote support to the TS3500 Tape Library (or its drives)
through a modem.
Hardware requirements for remote support by modem vary, depending on
whether you already have one or more IBM tape products that have the remote
support capability. Table 15 indicates the requirements.

Remote support through a system console
This section describes remote support to the TS3500 Tape Library through a system
console.
A system console is a service tool that is present in most environments where one
or more FICON/ESCON-enabled products, such as the IBM TS7700 Virtualization
Engine, are connected to a System z server (mainframe host).
The TS3000 System Console (TSSC) provides the same functionality to attach a
TS3500 Tape Library that is connected to an Open Systems server. The TSSC is a
personal computer (PC), complete with an Ethernet port. A customer
rack-mountable version of the TS3000 System Console is available by ordering
feature code 2732.

The rack-mount system console (FC 2724) comes with an Ethernet cable for
connection of one machine to an IBM-supplied modem. Feature code 2734 provides
one USB modem for use with FC 2724.
60 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 85
The customer rack-mountable TSSC (FC 2732) comes with serial cables and a
Keyboard Video Mouse (KVM). Feature code 2733 installs one internal modem in
the TSSC. The TSSC is preloaded with software and is tested prior to shipment.
When the TS3500 Tape Library is in an environment that includes a system
console, IBM recommends that the library perform the Electronic Customer Care
(ECC) Call Home function through the system console instead of through a direct
modem connection.
To perform an ECC Call Home operation through a system console, the TS3500
Tape Library sends Call Home information across a private Ethernet connection to
the system console. The system console then performs the ECC Call Home
operation and sends the information to the IBM Remote Technical Assistance
Information Network (RETAIN) through the system console's modem or Ethernet
(broadband) connection.
For remote support through a system console, the TS3500 Tape Library needs a
minimum of two Ethernet ports: one attached to your network for use by your
administrator and one attached to the private system console network for remote
support. New frame models L23 and L53 provide two Ethernet ports per frame so
no additional features are necessary. Frame models L22, L32, and L52 require an
Lx3 model conversion or the enhanced node card feature (FC 1700) in order to
support the dual Ethernet port requirement.
The library feature code 9217 provides an Ethernet cable for the remote support
connection from the TS3500 Tape Library to a system console.
Figure 13 on page 62 shows the attachment of a system console to the TS3500 Tape
Library for remote support. (Refer to Table 17 on page 62.)

Remote support security
This section describes the security design for remote support for the TS3500 Tape
Library through a system console.
The TS3000 System Console (TSSC) provides Ethernet connectivity to all attached
systems through a private internal network. Up to two modems can be attached to
the TSSC. The TSSC provides Point-to-Point Protocol (PPP) connectivity through
the modems to the private Ethernet network.
The TSSC also provides optional Ethernet outbound connectivity through the
customer's network to the IBM service support system, RETAIN
communication over this connection is restricted. The TSSC uses the following
ports: HTTPS: Port 443 HTTP: Port 80, and DNS: Port 53.
Figure 14 on page 64 shows an overview of network connectivity.

Dial Out security features
Dial out is used by the Call Home feature to send service-related
information from the attached systems to the IBM service support system,
RETAIN
®
; and to optionally send a pager message to a
customer-designated number. Dial out is available through the TSSC and
the modem. Dial out security properties for the Attached Systems are as
follows:
64 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
a69i0350
Page 89
1. Dial-out is from the customer location to the IBM connection point. The
IBM service support system (RETAIN®) does not initiate connections to
the attached systems.
2. Dial out through the TSSC can either be over a modem connection or
over an outbound Ethernet connection to the customer network. All
outbound traffic is limited to HTTP, HTTPS, and DNS information. All
service-related data is communicated using HTTPS and is therefore
encrypted.
3. The data exchanged between the attached systems and RETAIN
service-related data. The protocol used is specific to this application
and not publicly available.
4. On the first data exchange of each transmission, RETAIN
that the calling system is entitled to service. If the calling system is not
validated, it is disconnected.
5. The default setting for the call home feature is enabled. The Call Home
feature may be disabled by an IBM Service Representative.
None of the customer data stored on the tape or in memory for the TS3500
Tape Library is transmitted or accessed in a Call Home session. Call Home
is enabled or disabled by a CETool menu selection. When properly
configured, Call Home uses an IBM Global Services secure network or an
internet connection. A unique account code is used which establishes
connections only to RETAIN
Dial In security features
Dial in is used by IBM Service Representatives to logon to and provide
service support. Dialing in through the modem and TSSC, or WTI switch
for legacy systems, provides connectivity to the 3953 and 3494 Tape
Library managers. All dial-in connectivity to the TSSC must be through the
modem connection. The optional Ethernet connection restricts all incoming
traffic. Separate log ons are required for access to each of the Attached
Systems.

.
Note: TS3500 Tape Library does not support dial in.
The TSSC supports the following data security requirements when
properly configured:
v Customer data, stored on tape or in memory, can not be transmitted or
accessed in remote support sessions.
v Remote dial in is enabled or disabled through an operator panel or Web
specialist menu selection by the customer. The default is to disable
remote call in. When remote call in is enabled, the default is to enable it
for 24 hours.
v Remote dial in requires a password for access. The password is managed
by the customer.
The following dial in security properties are available:
Modem
The default modem setting for dial in is no password required. A
password can be specified by the customer and set by the IBM
Service Representative.
WTI Switch (used with some legacy systems)
The WTI Switch has a default password. A different password can
be set locally by the IBM Service Representative.
Chapter 1. Introduction 65
Page 90
Security for Encryption Support
Encryption support in the TS3500 Tape Library and 3592 tape controllers (models
C07, C06 and J70) allow system-managed tape encryption on IBM System z
platforms. An IBM service representative installs routers between the internal LAN
network, which is connected to the controllers, and the customer's LAN network.
The router provides access to the customer's key manager. Network traffic through
this router is outbound only. The Network Address Translation (NAT) function in
the router prevents externally-initiated connections to any internal components.
Port information for firewall environments
Table 19 shows the only ports that are required to be opened on the firewall for
environments where the tape configuration is separated from the LAN-attached
hosts and/or Web clients by a firewall. All other ports may be closed.

library) Protocol
Note: The TS3000 System Console uses the following ports: HTTPS: Port 443;
HTTP: Port 80; and DNS: Port 53.
Port information communications can be initiated either by the tape library or by
the host. Typically, the library only initiates a connection when responding to the
host; however, in the case of unsolicited messages such as statistics notifications
and operator interventions, the library initiates a connection through port 3494. If
the library manager needs to make a connection to the host, it chooses a temporary
port and uses that port to make an outbound connection to a 3494 listening port
on the host. When the host has a message to deliver to the library manager, it
chooses its own ephemeral port by which to make an outbound connection to
listening port 3494 on the library manager. The connection is only maintained for
the duration required to pass a single message, and then it is disabled.
Table 19 describes the minimum level of connectivity required to perform library
operations. Other ports that could be opened up on the firewall, but are not
necessary in order to have full functionality include:
v The standard HTTP port, 80, allows inbound communication to the library from
the IBM System Storage Tape Library Specialist (IBM's Enterprise Storage
Resource Management solution).
v Ports 161 and 162, which are the standard ports for sending SNMP traps. The
tape library can be configured to send traps to SNMP target machines in the
case of operator interventions, if you want to do that. In this case the firewall
needs to allow outbound connections from the library from its port 161 to port
162 on the listening SNMP target machine.

Remote support security for the TS3500 Tape Library through a system console
This section describes remote support security for the TS3500 Tape Library through
a system console.
Figure 15 illustrates all of the external communication connections to the TS3500
Tape Library control system.
Figure 15. External communication connections to the TS3500 Tape Library control system
Access to read and write data to and from tape cartridges is only available on the
host interface (Fibre Channel or SCSI). The host interface is provided by the drives.
The library communicates with the drives though the Library/Drive Interface. The
Ethernet port, modem port, and CETool port do not have any direct access to the
Library/Drive Interface. All communication between the various interfaces is
through the library control system.
All library communication requires explicit support by the library firmware
running in the library control system. The library firmware does not provide
capability for any of the following functions:
v Answering an incoming call to the modem.
v Communications between the Ethernet port and the modem port.
v Communications between the Ethernet port and the CETool port.
v Communications between the CETool port and the modem port.
v Accessing data from tape cartridges through the Library/Drive Interface.
v Sending or receiving data from tape cartridges through any port.

The TS3500 Tape Library Tape Library Specialist Web interface does not allow any
access to customer data, and it does not allow FTP or TELNET type operations. It
only provides those functions that are specifically coded in the library firmware.
The only files it can offload are library logs, drive logs, a backup of the nonvolatile
random access memory (NVRAM) configuration information for the library, and
certain usage and error statistics files. It cannot be used to read or write a customer
cartridge or otherwise access customer data.
The Tape Library Specialist Web interface allows the customer to set up an
administrator password, and no one without the password can use the Tape
Library Specialist Web interface to do anything to the library. The Tape Library
Specialist Web interface also provides several levels of access through roles, and
these roles have lower levels of access than the administrator. In addition, when
password protection is enabled, the Tape Library Specialist Web interface also
provides an option to authenticate through the Storage Authentication Service
(SAS). See the section about Web security in the IBM System Storage TS3500 Tape
Library with ALMS Operator Guide.
Security concerns when using the Tape Library Specialist Web interface are similar
to those of using the operator panel. For example:
v A specialist user could move a cartridge from one location to another within the
library, potentially confusing a host application or making a cartridge
unavailable by moving it to a different partition.
v A user could re-configure the library, possibly causing problems at the hosts
because of changes in partitioning or device IDs.
v A remote user could update library or drive code. However, since the library
and drives ignore any code they do not recognize, the only exposure is to
loading down level code.
These security concerns can be addressed by utilizing the password, user role, and
authentication features provided by the Tape Library Specialist Web interface and
also by enabling SNMP audit logging. When SNMP audit logging is enabled, the
library sends notifications when certain events occur in the library. For more
information, refer to “SNMP audit logging” on page 71.
Security considerations for the IBM TS3500 Tape Library RS/232 Port
This section describes security information for the IBM TS3500 Tape Library
RS/232 Port through the debug/CETool interface.
When servicing a TS3500 Tape Library, IBM Service Representatives may connect a
service terminal (laptop computer) to an RS-232 serial port on the TS3500 Tape
Library. Serial port J1 (also known as the CETool Port) provides an interface which
allows IBM Service Representatives to send messages to the library and receive
information from the library. This is a proprietary interface which provides specific
commands and only passes the data associated with those commands.
A program called CETool.exe is used to interface with the library through this port.
The CETool program provides the following capabilities:
v Update library or drive firmware by transferring a library code image or a drive
code image from the service terminal to the library
v Get error and statistics logs and configuration information from the library and
drive
v Configure the library settings related to the Call Home facility
68 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 93
v Backup and restore the library non-volatile random access memory (NVRAM)
(configuration data)
v Correct a tape drive serial number that has been corrupted
v Specify whether to report 5 characters or 7 characters of the library serial
number in inquiry data
The CETool Port interface does not provide any capability to access data that has
been written on the tape cartridges within the library. In addition, the CETool Port
interface does not provide any capability to access any Ethernet network connected
to the library.
For more information about installing and using the CETool, see the IBM System
Storage TS3500 Tape Library 3584 Maintenance Information manual.
Methods of cleaning drives
This section describes the methods of cleaning that the TS3500 Tape Library uses
for its drives.
Notes:
v It is the operator's responsibility to monitor cleaning cartridge usage.
v Automatic cleaning is always enabled with the Advanced Library Management
System (ALMS).
The head of every tape drive in the TS3500 Tape Library must be kept clean to
prevent errors caused by contamination. To help you keep the drives clean, IBM
provides a cleaning cartridge with the library. Whenever a drive determines that it
needs to be cleaned, it alerts you with a message on the library's display or host
console. The library uses the cleaning cartridge to clean the drive with whatever
cleaning method that you choose. In all methods, cleaning is performed after the
data cartridge has been unloaded from the drive and before the next load.
Two methods of cleaning are available:
Automatic cleaning (preferred)
Automatic cleaning enables the library to automatically respond to any
tape drive's request for cleaning and to begin the cleaning process. The
cleaning process is transparent to any host application that uses the library.
Automatic cleaning is required, and cannot be disabled, in libraries with
the Advanced Library Management System (ALMS). For more information,
see the section about automatic cleaning in the IBM System Storage TS3500
Tape Library with ALMS Operator Guide.
Manual cleaning
Manual cleaning requires that you select a menu option from the library's
operator panel or Tape Library Specialist Web interface to perform cleaning
on one or more of the tape drives. Manual cleaning is always supported,
regardless of whether automatic cleaning is enabled or disabled. For more
information, see the section about performing a manual cleaning operation
in the IBM System Storage TS3500 Tape Library with ALMS Operator Guide.
TapeAlert support
This topic gives an overview of the TapeAlert technology, which is supported by
the IBM System Storage TS3500 Tape Library.
Chapter 1. Introduction 69
Page 94
The TS3500 Tape Library is compatible with TapeAlert technology, which provides
error and diagnostic information about the drives and the library to the host
application. The library provides this information as TapeAlert flags that are
reported to the application by the SCSI LOG SENSE command.
For a list of the TapeAlert flags for the drives and the library, see the appropriate
section in the IBM System Storage TS3500 Tape Library with ALMS Operator Guide.
SNMP messaging
This section describes the Simple Network Management Protocol (SNMP), which
allows the TS3500 Tape Library to send alerts over a LAN network to a monitoring
server.
Occasionally, the TS3500 Tape Library may encounter a situation that you want to
know about. These can be conditions that affect library performance, such as an
open door that causes the library to stop, or user actions that you want to have
logged, such as a cartridge move or export that is specifically initiated from the
Tape Library Specialist web interface or the library's operator panel. SNMP
messages can alert you of these conditions.
The library provides a standard TCP/IP protocol called SNMP to send alerts about
conditions (such as an opened door) over a TCP/IP LAN network to an SNMP
monitoring server. These alerts are called SNMP traps. Using the information
supplied in each SNMP trap, the monitoring server (together with
customer-supplied software) can alert operations staff of possible problems or
operator interventions that occur. Many monitoring servers (like NetView
used to send e-mail or pager notifications when they receive an SNMP alert (for
more information, see your NetView documentation or the manuals for your
network management application).
(R)
) can be
The monitoring server must be loaded with systems management software that can
receive and process the trap. SNMP supports a get and get-response mechanism
for an operator to gather more information about a problem or query the library
about its current status. Through a monitoring server, the operator issues a "get"
via SNMP to request information about the library. A get-response is the
information that is provided in response to the get. This type of support generally
requires an up-to-date library Management Information Base (MIB). The library's
MIB contains units of information that specifically describe an aspect of a system,
such as the system name, hardware number, or communications configuration.
IBM provides the MIBs that are supported by the library. They include:
v IBM 3584 MIB for Version 1 or Version 2c traps
v Storage Networking Industry Association (SNIA) Storage Media Library (SML)
MIB Version 1.12
v SNIA SML MIB Version 1.20b
Refer to “Obtaining MIBs” on page 71 for step-by-step instructions for
downloading the correct MIB for your operating system.
An operator cannot change library settings by using SNMP. Settings can only be
changed by using the Tape Library Specialist web interface or operator panel.
Figure 16 on page 71 shows the flow of SNMP communication from the library
over the Ethernet local area network (LAN) to an SNMP monitoring server.

SNMP audit logging
This topic describes the Simple Network Management Protocol (SNMP) audit
logging, which provides logging information about specific TS3500 Tape Library
user actions.
The TS3500 Tape Library provides various interfaces, other than the host
application, that allow a user to configure different library or drive settings, move
cartridges within or out of the library, and perform other actions. In order to
provide additional capabilities for monitoring these actions and the physical
security of the library, the TS3500 Tape Library provides notifications, in the form
of SNMP traps, that provide a log of when certain activities are performed.
SNMP audit logging sends the log information over a TCP/IP LAN network to an
SNMP monitoring server, just as SNMP traps are sent for library alerts. By default,
Chapter 1. Introduction 71
Page 96
SNMP audit logging is disabled, however, you can enable SNMP audit logging
using the TS3500 Tape Library Specialist Web interface.
The following events are logged when SNMP audit logging is enabled:
v Log in attempt granted or denied
v Logout (timeout, logout, or force logout)
v Any configuration change
v Any data or cleaning cartridge move initiated from a library user interface
v Any code load operation (library or drive) initiated from a library user interface
and not associated with a FRU replacement
v Any prepare or finish service procedure initiated from a library user interface
including set storage slot offline or online
v Any drive serial number change not associated with a FRU replacement
v Any drive power cycle initiated from a library user interface
v Any node card reset initiated from a library user interface
Notes:
v Each login and logout is only logged if security is enabled.
v Door open is logged whether or not SNMP Audit Logging is enabled.
The following information is provided in the logs for each of the events listed
above:
v Machine type, model, and serial number of the reporting machine
v The UserID initiating the event
v Level of severity
v Trap ID
v Description of the event
SMI-S support
Note: The UserID is only applicable for the Web when security is enabled and for
operations performed from the operator panel.
This section describes the Storage Management Initiative - Specification (SMI-S)
service provided by the TS3500 Tape Library.
SMI-S defines a standard interface for interoperable, extensible, and secure
management of heterogeneous and distributed storage systems. This interface uses
an object-oriented, XML-based, messaging-based protocol designed to support the
specific requirements of managing devices such as the TS3500 Tape Library in a
storage environment. The SMI-S specification describes the information available to
a WBEM client, such as the IBM Tivoli Storage Productivity Center (TPC), from an
SMI-S-compliant CIM WBEM Server such as the TS3500 Tape Library. This SMI-S
standard storage management interface is developed by the Storage Network
Industry Association (SNIA).
The TS3500 Tape Library provides native support for SMI-S. It is no longer
necessary to run a proxy SMI-S agent on a separate Linux machine. All of the
functions present in the proxy SMI-S agent are replicated in this embedded
version. In addition, this embedded version includes support for asset reporting on
each installed frame in the TS3500 Tape Library.
72 IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
Page 97
New base frame models L23 and L53 come with support for the embedded SMI-S
Agent. Other frame models, however, require upgrades in order to support the
embedded SMI-S Agent. The following table displays the frame models and
required upgrades.
Table 20. Required upgrade for those frames providing Ethernet attachment to the SMI-S

L52, D52 Installation of feature code 1700 or 1701
or model conversion to L53 or D53
L53, D53 No upgrade required
The TS3500 Tape Library SMI-S HTTP service operates on the library Ethernet
interface IP address on port 5988 by default. The SMI-S service agent can be
enabled and disabled using the library Web interface (see the appropriate section
in the IBM System Storage TS3500 Tape Library with ALMS Operator Guide). The
TS3500 Tape Library embedded SMI-S service uses "root/ibm" as the Namespace.
Namespace is a configuration parameter needed to access the SMI-S service for an
SMI-S client such as TPC.
The user authentication and security (SSL) for the SMI-S service works in
conjunction with the Web service. When the Web user accounts are enabled, the
same user accounts and passwords are used for SMI-S service authentication.
When Web SSL is enabled, the SMI-S HTTPS service is enabled on port 5989 and
the SMI-S HTTP service is disabled on port 5988.
An SMI-S profile is a subset of the SMI-S standard that supports interoperability in
managing specific products such as tape libraries. A profile is a vertical slice
through the SMI-S standard defining physical, logical, and behavioral elements
required for interoperability.
The TS3500 Tape Library embedded SMI-S service supports the following profiles:
Table 21. Embedded SIM-S Agent Profiles

http://www.ibm.com/systems/storage/software/. To learn more about SMI-S and
SNIA, go to http://www.snia.org/.
Secure Socket Layer (SSL) functionality
The TS3500 Tape Library supports secure socket layer (SSL). SSL is a protocol for
transmitting private documents through the Internet. SSL uses a cryptographic
system that uses these two keys to encrypt data:
v a public key known to everyone
v a private key known only to the recipient of the message
Many Web sites use this protocol to obtain confidential user information, such as
credit card numbers. By convention, URLs that require an SSL connection start
with https: instead of http:.
The TS3500 Tape Library provides the ability to enable or disable SSL for Web
browser communication. The action is performed using the Tape Library Specialist
Web specialist.
Storage Authentication Service
This topic describes the Storage Authentication Service (SAS), which is an option
for web login requests on the TS3500 Tape Library.
Remote authentication is supported on a TS7700 Virtualization Engine or TS3500
Tape Library using the Tivoli Secure Authentication Service client and server, and
the WebSphere
TS3500 Tape Library must connect to a System Storage Productivity Center (SSPC)
appliance or a server using Tivoli Productivity Center (TPC). The SAS client is
integrated into the TS7700 Virtualization Engine microcode or the TS3500 Tape
Library firmware, while the SAS server and the WebSphere Federated Repositories
are integrated into TPC 4.1 and higher. TPC is available as a software-only package
or as an integrated solution on the SSPC appliance.
When SAS is enabled, the TS3500 Tape Library passes user authentication requests
to the SAS server on the SSPC or TPC, where they are forwarded to the customer's
Lightweight Directory Access Protocol (LDAP) or Microsoft Active Directory (AD)
server. The LDAP or AD server then authenticates the user's ID and password; if
they are valid then one or more user groups are assigned. The TS3500 Tape Library
then assigns the user a role based on the LDAP or AD group.
This central repository allows you to accomplish the following security tasks from
a single interface, without logging in to a TS3500 Tape Library:
v Add or remove a user
v Reset or change a password
v Assign, change, or delete the LDAP or AD group of a user

Figure 17. Storage Authentication Service overview
A central repository can also simplify the process of responding to new security
requirements for one or more tape libraries. For instance, rules for passwords can
be changed in one location without reconfiguring multiple, affected machines. By
comparison, when local authentication is employed, each individual machine
maintains an internal database of user IDs, with corresponding passwords and
roles.
LDAP dependency
The WebSphere Federated Repositories component of the SSPC or TPC receives
authentication requests from the TS3500 Tape Library through the SAS. The SAS
passes user ID and password information to the LDAP or AD server. The LDAP or
AD server returns authentication status to the SSPC or TPC, which forwards the
authentication status through the SAS to the TS3500 Tape Library. The LDAP or
AD server attached to the SSPC or TPC manages the following information:

User ID
A string to identify a specific user
User password
A password for each user ID
Groups
Strings to identify one or more groups of users. The TS3500 Tape Library
maps each LDAP group to a TS3500 Tape Library role.
Each user is defined as a member of one or more groups, meaning the user
assumes the roles defined by those groups.
Notes:
v The User ID and User password cannot exceed 15 characters. LDAP users that
exceed this maximum may not be able to authenticate to the TS3500 Tape
Library Specialist Web interface when SAS is enabled.
v The maximum length of a Group is 15 characters. Groups exceeding 15
characters in length will not map to a defined role in the TS3500 Tape Library.
Chapter 1. Introduction 75
Page 100
Mapping groups to roles
When a user is successfully authenticated using the Storage Authentication Service,
the resulting user information includes a list of groups the user belongs to. For
successful authorization, at least one LDAP group in the list must have the same
name as a role that is defined in the TS3500 Tape Library. The first LDAP group to
match a role determines the role of the user. Avoid ambiguity of multiple matches
by making sure that only one group matches a role in the TS3500 Tape Library.
Note: Prior to firmware level A040, a user in an Admin LDAP group is required to
enable and disable SAS.

TPC security features, including how to use Microsoft Active Directory for
authentication, visit the web at http://publib.boulder.ibm.com/infocenter/
wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/
cwim_fedrepos.html.
IPv6 functionality
The TS3500 Tape Library supports internet protocol (IP) addresses in both IPv4 and
IPv6 format. IPv6 is designed to allow the Internet to grow steadily, both in terms
of the number of hosts connected and the total amount of data traffic transmitted.
Both the operator panel and the Tape Library Specialist Web interface allow the
definition of IPv4 and IPv6 addresses. The Key Proxy determines the IP version
used and presents the correct IP address and parameters to the IP Stack.
IPv4 and IPv6 address formats
An IPv4 address has the following format: x.x.x.xwhere x is called an octet
and must be a decimal value between 0 and 255. Octets are separated by periods.
An IPv4 address must contain three periods and four octets. Examples of valid
IPv4 addresses include:
v 1.2.3.4
v 01 . 102 . 103 . 104
Here is an example of a screen that uses IPv4 addresses:
Ethernet IPv4 Panel 0175
