DANGER
v Always lower the leveling pads on the rack cabinet.
v Always install stabilizer brackets on the rack cabinet.
v To avoid hazardous conditions because of uneven mechanical loading,
always install the heaviest devices in the bottom of the rack cabinet.
Always install servers and optional devices, starting from the bottom
of the rack cabinet.
v Rack mounted devices are not to be used as a shelf or workspace. Do
not place any object on top of rack mounted devices.
v Each rack cabinet might have more than one power cord. Be sure to
disconnect all power cords in the rack cabinet before you service any
device in the rack cabinet.
v Connect all devices that are installed in a rack cabinet to power
devices installed in the same rack cabinet. Do not plug a power cord
from a device that is installed in one rack cabinet into a power device
that is installed in a different rack cabinet.
v An electrical outlet that is not correctly wired might place hazardous
voltage on the 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.
CAUTION:
(R001)
v Do not install a unit in a rack where the internal rack ambient
temperatures might exceed the manufacturer's recommended ambient

v Do not install a unit in a rack where the air flow is compromised.
Ensure that air flow is not blocked or reduced on any side, front, or
back of a unit that is used for air flow through the unit.
v Consideration must be given to the connection of the equipment to
the supply circuit so that overloading of the circuits does not
compromise the supply wiring or overcurrent protection. To provide
the correct power connection to a rack, refer to the rating labels on the
equipment in the rack to determine the total power requirement of the
supply circuit.
v (For sliding drawers) Do not pull out or install any drawer or feature
if the rack stabilizer brackets are not attached to the rack. Do not pull
out more than one drawer at a time. The rack might become unstable
if you pull out more than one drawer at a time.
v (For fixed drawers) This drawer is a fixed drawer and must not be
moved for servicing unless specified by the manufacturer. Attempting
to move the drawer partially or out of the rack might cause the rack
to become unstable or cause the drawer to fall out of the rack.
Safety and environmental noticesxiii
CAUTION:
Removing components from the upper positions in the rack cabinet
improves rack stability during relocation. Follow these general
guidelines whenever you relocate a populated rack cabinet within a
room or building:
v Reduce the weight of the rack cabinet by removing equipment,
starting at the top of the rack cabinet. When possible, restore the rack
cabinet to the configuration of the rack cabinet as you received it. If
this configuration is not known, you must do the following:
– Remove all devices in the 32U position and above.
– Ensure that the heaviest devices are installed in the bottom of the
rack cabinet.
– Ensure that there are no empty U-levels between devices that are
installed in the rack cabinet below the 32U level.
v If the rack cabinet you are relocating is part of a suite of rack cabinets,
detach the rack cabinet from the suite.
v Inspect the route that you plan to take to eliminate potential hazards.
v Verify that the route that you choose can support the weight of the
loaded rack cabinet. Refer to the documentation that comes with your
rack cabinet for the weight of a loaded rack cabinet.
v Verify that all door openings are at least 760 x 2032 mm (30 x 80 in.).
v Ensure that all devices, shelves, drawers, doors, and cables are secure.
v Ensure that the four leveling pads are raised to their highest position.
v Ensure that there is no stabilizer bracket that is installed on the rack
cabinet during movement.
v Do not use a ramp that is inclined at more than 10 degrees.
v When the rack cabinet is in the new location:
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet.
– If you removed any devices from the rack cabinet, repopulate the
rack cabinet from the lowest position to the highest position.
v If a long-distance relocation is required, restore the rack cabinet to the

Encryption
The bar code reader is a part of the library accessor. The bar code reader reads
each cartridge bar code label that identifies the types of cartridge magazines and
tape drive that is installed in the library. It also provides inventory feedback to the
host application, Operator Panel, and Web User Interface. The library stores the
customized inventory data in memory. Library firmware supportsa6or
8-character volume serial number (VOLSER) on the bar code label on the tape
cartridge.
The Ultrium 4, Ultrium 5, and Ultrium 6 Half-High Tape Drives support the Serial
Attached SCSI (SAS) interface. The SFF-8088 SAS connector on the Ultrium 4,
Ultrium 5, and Ultrium 6 is compatible with SAS-1 or SAS-2 cables.
A drive with a SAS (Serial Attached SCSI) interface is linked directly to controllers.
SAS is a performance improvement over traditional SCSI. SAS enables multiple
devices (up to 128) of different sizes and types to connect simultaneously with
thinner and longer cables. Its full-duplex signal transmission supports 6.0 Gb/s
(S4H, S5H, and S6H). In addition, the TL1000 Tape Autoloader is hot-plugged, if
necessary. SAS drives can auto-negotiate speed.
The LTO Ultrium 6, Ultrium 5, and Ultrium 4 Tape Drives support host
Application Managed Encryption (AME) with T10 encryption methods, for SAS
drives. Data encryption is supported by LTO Ultrium 6, Ultrium 5, and Ultrium 4
Data Cartridges only.
Note: Application Managed Encryption (AME) does not require a key.
The encryption enabled drive contains the necessary hardware and firmware to
encrypt and decrypt host tape application data. Encryption policy and encryption
keys are provided by the host application or host server. A drive digital certificate
is installed at manufacturing time. Each drive receives a unique serial number and
certificate. The T10 application validates each drive instance by checking the
drive’s digital certificate.
The LTO Ultrium encryption environment is complex and requires knowledge
beyond that of product trained Service Support Representatives (SSRs). The
Encryption function on tape drives (desktop, stand-alone, and within libraries) is
configured and managed by the customer. In some instances, SSRs are required to
enable encryption at a hardware level when service access or service password
controlled access is required. Customer setup support is by Field Technical Sales
Support (FTSS), customer documentation, and software support for encryption
software problems. Customer 'how to' support is also provided by way of support
line contract.
The encryption-capable library firmware allows the user to select None or
Application Managed encryption from the Web User Interface. The factory default
is None.
Occasionally, the library might encounter a situation that you want to know about,
such as an open magazine or a fault that causes the library to stop. The library
provides a standard TCP/IP protocol called Simple Network Management Protocol
(SNMP) to send alerts about conditions (such as need for operator intervention)
over a TCP/IP LAN network to an SNMP monitoring station. These alerts are
called SNMP traps. With the information supplied in each SNMP trap, the
monitoring station (together with customer-supplied software) can alert operations
personnel of possible problems or operator interventions that occur.
SNMP traps
SNMP Traps are alerts or status messages that can be collected, monitored, and
used to proactively manage attached libraries with SNMP protocol with the SNMP
monitoring stations. In summary, each trap provides the following information:
v Product Identification such as product name, description, manufacturer, model
number, firmware level, and the URL that the trap is designated for.
v Product Status such as the severity of the trap, status (current and previous) and
the time the trap occurred.
v Library State (physical device status) such as identification and status of devices
that is monitored. It would include enclosure, power supply, controller,
magazine status, drive count, cartridge slot count, and I/O station count. Also
included would be certain library statistics, and where appropriate, the fault FSC
(fault symptom code) including the severity and description of that fault.
v Drive Status such as the identification of each drive in the library, firmware
level, serial number, and other address and status information.
v Trap Definitions such as library status change, open magazine, I/O accessed,
hard fault information, requests to clean the drive, excessive retries, and
returning to normal operations.
v SNMP MIBs: The library's Management Information Base (MIB) contains units
of information that specifically describe an aspect of the system, such as the
system name, hardware number, or communications configuration. When with
|
SNMP to monitor your TL1000 Tape Autoloader, make sure that the TL1000 MIB
file is loaded on your SNMP monitoring station. SNMP traps are sent to the
SNMP monitoring stations that are defined for your library (see “Configuring
SNMP trap notifications” on page 4-31).
Network Time Protocol
NTP is an Internet standard protocol that assures accurate synchronization of
computer clock times in a network of computers. Running as a continuous
background client program on a computer, NTP sends periodic time requests to a
server, obtaining server time stamps, and with them to adjust the client’s clock.

Figure 1-6. Ultrium half-high tape drive
The TL1000 Tape Autoloader supports the Ultrium 4 (S4H), Ultrium 5 (S5H), and
Ultrium 6 (S6H) half-high tape drives.
The Ultrium 4, Ultrium 5, and Ultrium 6 half-high tape drives support the Serial
Attached SCSI (SAS) interface. They have one Mini-SAS (SFF-8088) connector.
Speed matching
a80hh015
Media
|
|
To improve system performance, the Ultrium 4, Ultrium 5, and Ultrium 6 Tape
Drives use a technique that is called speed matching to dynamically adjust its
native (uncompressed) data rate to the slower data rate of the attached server.
Channel calibration
The channel calibration feature of the Ultrium 4, Ultrium 5, and Ultrium 6 Tape
Drives 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 characteristics.
Power management
The Ultrium 4, Ultrium 5, and Ultrium 6 Tape Drives feature a power management
function. This function controls the drive’s electronics so that part of the electronics
completely turns OFF when circuit functions are not needed for the drive’s
operation.
The TL1000 Tape Autoloader uses Ultrium tape cartridges that provide up to
2500-GB native capacity (up to 6250 GB with 2.5:1 hardware data compression) for
Ultrium 6 tape drives, 1500-GB native capacity (up to 3000 GB with 2:1 hardware
data compression) for Ultrium 5 tape drives, and 800-GB native capacity (up to
1600 GB with 2:1 hardware data compression) for Ultrium 4 tape drives.

For more information about media compatibility, see Chapter 5, “Media,” on page
5-1.
Logical Unit Number (LUN) scanning
|
The TL1000 Tape Autoloader uses a single SCSI ID and dual LUNs to control the
tape drive (LUN 0) and library accessor (LUN 1). The library requires a Host Bus
adapter (HBA) that supports LUN scanning. If it is not enabled, your host system
cannot scan beyond LUN 0 and fails to detect the library. It sees only the tape
drive.
Important: Some HBAs, such as RAID controllers, do not support LUN scanning.
Location coordinates and element addresses
|
The TL1000 Tape Autoloader incorporates patented high-density (HD) slot
technology, which allows multiple cartridges to be stored in a tiered architecture.
The depth of a cartridge location in a high-density slot is known as a tier.
High-density slots are designed to contain multiple cartridges in Tiers 1 and 2.
Note: Each column has a spring-loaded mechanism that pushes a tape cartridge
into Tier 1 when it is the only cartridge in that column. A single cartridge in
a column takes on the Tier 2 element address even though it is physically in
Tier 1.

Note: The operating environment of the library must not conflict with the media storage
requirements. The library can operate at elevated temperatures for an extended period.
However, the temperature might shorten the useful life of media that is stored in the
library. If media is stored in the library for more than 10 hours, the storage temperature
requirements for media are met. It is assumed that media stored in the library is
approximately 2 degrees above ambient temperature when the library is powered ON.
