– Remove all devices in the 32U position (compliance ID RACK-001) or 22U (compliance ID RR001)

and above.

– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.

xviii Dell EMC ML3 Tape Library: User's Guide

– Ensure that there are little-to-no empty U-levels between devices installed in the rack-cabinet below

the 32U (compliance ID RACK-001) or 22U (compliance ID RR001) level, unless the received
configuration specifically allowed it.

v If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the

suite.

v If the rack cabinet you are relocating was supplied with removable outriggers, they must be reinstalled

before the cabinet is relocated.

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 no stabilizer bracket 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, complete these steps.

– 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 configuration of the rack cabinet

as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower
the leveling pads to raise the casters off the pallet and bolt the rack cabinet to the pallet. (R002)

Physical numbering of storage slots starts with the left magazine of the lowest module of your library. In
this module, the numbers of the lowest row (1, 6, 11, 16, 21, 26, 31, 36) are inaccessible to the accessor so

10 Dell EMC ML3 Tape Library: User's Guide

that only 32 cartridges can be loaded. As modules are added above this module, the numbering
continues, starting with the lower left slot of the left magazine, and adding 40 storage slots for each
additional module.

Each module can be configured to contain an I/O Station, or one I/O Station can be accessed by several
modules. I/O Stations consist of five slots in the front column of the right magazine of each module,
except for the lowest module. The lowest module in a library can contain a 4-slot I/O Station only. To
enable or disable I/O Stations, go to Library > Modules and Magazines > Actions > Enable or Disable
I/O Station in the Management GUI.

Power supply

The library provides a single power supply with each library. However, a secondary redundant power
supply for the base module can be added. In addition, each expansion module with drives installed
requires a power supply.

Bar code reader

The high-speed bar code reader is a part of the Base Module. The bar code reader provides inventory
feedback to the host application, Operator Panel display, and Management GUI by reading cartridge bar
code labels. The library stores the customized inventory data in memory.

Library firmware supports a 6 or 8 character volume serial number (VOLSER) on the bar code label on
the tape cartridge. It is highly recommended to use bar code labeled cartridges. See “Labeling tape
cartridges” on page 145.

User interfaces

This library has two user interfaces.
v “The Management GUI” on page 59 - With the Management GUI, you can monitor, configure, and

control the library from a web browser. The Management GUI hosts a dedicated, protected Internet site
that displays a graphical representation of the library. For information on network connectivity, see

Speeds of
connectivity Native data rate

The LTO tape drives communicate with the library through an internal Ethernet interface. For enhanced
performance, the LTO tape drives include speed matching, channel calibration, and power management.
Speed matching dynamically adjusts the drive’s normal 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 characteristics. Power management reduces the
drive’s power consumption during idle power periods.

Control path drives

A control path is a logical path to the library. A control path is the path for SCSI Medium Changer
commands sent by a server to control a specific logical library. The library has no direct SCSI connection
to a host server. When a software host server communicates with the library, it sends the communication
by way of a tape drive. The tape drive is designated as a control path drive.

Mixed drives

All supported generations of LTO tape drives and cartridges can be in the same physical library and
within a single module.

12 Dell EMC ML3 Tape Library: User's Guide

This library supports a mixture of LTO drive types in a logical library. Some independent software
vendors (ISVs) support mixed drive types within a logical library and other do not. Some ISVs that
support mixed drive types might have restrictions. For details, contact your ISV.

Figure 17 shows examples of methods for mixing LTO drive types in a logical library.

Physical and logical addresses of drives

The library assigns each tape drive a unique address to indicate its physical location, shown in Figure 22
on page 16. The physical numbering is bottom up on all drives. This information is shown on the Drives
page of the Management GUI.

Overview 15

Figure 22. Physical numbering of drives

The library assigns each tape drive a SCSI element address that consists of a value that defines a logical
location in the library to the SCSI interface. It is assigned and used by the application when the host
server processes SCSI commands. The SCSI element address for a drive is unique to the location of the
drive. It does not vary based on other drives in the library. See “Library partitioning” on page 57.

Supported tape cartridges

Within the library, the supported LTO tape drives use the following cartridge types:

v LTO8 Data Cartridge
v LTO8 WORM Data Cartridge

Library functions

Encryption

All supported tape drives in this library support encryption.

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 might validate each drive instance by checking the drive's
digital certificate.

The library provides these options.

1. Encryption disabled

2. Application Managed Encryption (AME)

3. Library Managed Encryption (KMIP) (LME). LME is a built-in feature. For configuration details, see

“Configuring Library Managed Encryption (KMIP)” on page 70.

The default is Application Managed Encryption.

Enabling library-managed encryption on a Dell EMC ML3 is a six-step process.

1. Upgrade the library and drive firmware to the current versions. The firmware can be found at

www.Dell.com/support.

2. Library-managed encryption on the library is already activated and cannot be deactivated.

If issues occur with the library-managed encryption on the library, go to http://www.dell.com/
tapeautomation for information on resolving the issue. If your issue is not resolved, contact Dell
technical support.

3. Configure library-managed encryption on your library.

4. Install the IBM SKLM application on the server that is designated as the key manager. See IBM SKLM

Knowledge Center for information.

5. Configure the IBM SKLM application. See IBM SKLM Knowledge Center for information.

6. Start the IBM SKLM application. See IBM SKLM Knowledge Center for information.

Note: All encryption settings must be configured or reverified in the drive after any library or drive
reset. A new drive might be added or an existing drive might be swapped with another drive.

Library sharing

The library can be configured into one or more logical libraries that can be shared by multiple
applications.

It is advantageous to be able to share a single physical library between heterogeneous or homogeneous
applications. However, some applications (and some servers) do not allow for sharing a library between
systems.

The library Management GUI provides two methods for logical library configuration.

1. A quick configuration for a simple one logical library configuration

2. An advanced configuration action for a multiple logical library configuration

Overview 17

The second method gives the ability to create configurations that enable the library to process commands
from multiple heterogeneous applications (such as a Windows application) and multiple homogeneous
applications (for example, the same application run by several System p servers). See “Advanced library
configuration” on page 55.

Path failover and load balancing

The path failover feature ensures the use of a redundant communication path when the primary path
fails.

Command failures and time outs are costly. You want your library to run smoothly and efficiently. Path
failover capabilities allow the 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. The
path failover feature can be ordered from the factory, or you can order it as a field upgrade. The path
failover feature is activated on the Management GUI. To order features, contact your Sales Representative
or Business Partner.

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. Path failover is where redundancy is in the path from the application to the intended
target (the library accessor or the drive mechanism), 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 library.

DPF includes load balancing of the HBAs because the channel is a data-intensive path (the control path
carries 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 where multiple HBA paths are 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 current device driver. They are supported exclusively with
products that bear the Dell logo on the operating systems that is indicated in Table 15.

Table 15 summarizes the differences between CPF, DPF, and load balancing.

Alerts and logging

The library sends alerts about the library and attached tape drives, and offers audit-logging to track user
actions.

v TapeAlert Support: The 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 error and diagnostic information as TapeAlert flags that are reported to the application by
the SCSI LOG SENSE command. See “TapeAlert flags” on page 95.

v Email (SMTP - Simple Mail Transfer Protocol) Notifications: The library can configure email

notification of library events. The library must have network access to an SMTP server. See “Locating
Management functions” on page 63.

v Remote Logging (rsyslog): The library can send syslog (system log) notifications to a configured

remote (rsyslog) server. When system events occur, the ML3 tape library creates a log of these events.
With this notification feature configured, the library sends a notification of the event to the syslog
server. The syslog server keeps its own log of system events. (The syslog server is a customer-provided
server.) See “Locating Management functions” on page 63.

v SNMP Support: The Simple Network Management Protocol (SNMP) allows the library to send alerts

over a LAN network to a monitoring server.
Occasionally, the library might encounter situations that you want to know about. These situations can

be conditions that affect the library performance, such as an open door that causes the library to stop.
You might also want to log user actions, such as a cartridge move or export that is initiated from the
Management GUI. SNMP messages can alert you of these conditions.

The library provides a standard TCP/IP protocol that is called SNMP to send alerts about conditions
over a TCP/IP LAN network to an SNMP monitoring server. These alerts are called SNMP traps.
Using the information that is 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 can be used to send email or pager notifications when they
receive an SNMP alert. See the manual for your network management application.

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 status. Through a monitoring server, the operator enters
a "get" using 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 SNMP server's MIB contains units of information that
specifically describe an aspect of a system, such as the system name, hardware number, or
communications configuration.

SNMP Notification Levels

Overview 19

SNMP provides various levels of notification about specific library events and user actions.
– Inactive – No events are sent.
– Critical – Only critical events are sent.
– + Warnings – Only critical and warning events are sent.
– + Configuration – Only critical, warning, and configuration events are sent.
– + Information – All events are sent.
Simple Network Management Protocol (SNMP) audit logging provides logging information about

specific tape library user actions. To configure SNMP, see “Locating Management functions” on page

63.

Host connectivity

Compatible servers and software

The library is supported by a wide variety of servers, operating systems, and adapters. There are many
ways to determine the servers and software that support this library.

These attachments can change throughout the lifecycle of the product. To determine the newest
attachments, or to get a comprehensive list of compatible software, do one of the following actions.

v For a list of compatible software, operating systems, and servers for LTO tape drives, see

www.Dell.com/support.

Notes:

1. Dell does not provide application software with this library. To order software, contact your sales

representative, Business Partner, or an independent software provider.

2. If you attach your library to a server with non-Dell software, contact your software vendor for a

matrix of compatible hardware, software, firmware revisions, and adapter cards.

Note: The library requires an HBA with multiple LUN supports. Also, multiple LUN supports must be
enabled on the host computer. When multiple LUN supports are not enabled, the host computer can see
the tape drive, but not the library.

Supported device drivers

Dell provides device driver support for the LTO tape drives, and the robotics in this library.

Dell maintains the current levels of device drivers and driver documentation on the web. Go to
www.Dell.com/support and follow the steps to access this material.

Network connectivity

Supported browsers

|

IBM supports higher versions of the browsers if the vendors do not remove or disable functions that the

|

product relies upon. For browser levels higher than the versions that are certified with the product,

|

customer support accepts usage-related and defect-related service requests. As with operating system and

|

virtualization environments, if IBM support cannot re-create the issue in the lab, the client might be asked

|

to re-create the problem on a certified browser version to determine whether a product defect exists.

|

Defects are not accepted for cosmetic differences between browsers or browser versions that do not affect

|

the functional behavior of the product. If a problem is identified in the product, defects are accepted. If a

|

problem is identified with the browser, IBM might investigate potential solutions or workarounds that the

|

client can implement until a permanent solution becomes available.

Planning

The library requires an environment able to accommodate the appropriate space, power, location, and
other technical specifications. Use this section as a reference for onsite requirements to allow for optimum
operation of the library. Save your settings in the Appendix A, “Library Configuration Forms,” on page

137.

Library Layout and Location requirements

For tabletop installation - Tabletop installations (one Base Module) require no additional hardware.

For rackmount installation - If possible, install the Base Module in the middle of the rack to provide
space for the allowed three Expansion Modules above it and three Expansion Modules below it. See
“Structure and supported library configurations” on page 2 for details.

Security

The equipment must be located so that access to the equipment can be controlled and monitored.
Consider all of these recommended security measures when you are determining where to locate your
tape library.

Library location

You are responsible for the security of this library, the cartridges that are contained within the
library, and shelf-resident cartridges. To prevent unauthorized access to data, Dell recommends
locating the library and all shelf-resident cartridges in an area where access is controlled.

Onsite security measures

You are also responsible for evaluating, selecting, and implementing security features,
administrative procedures, and appropriate controls in application systems and communication
facilities.

Data security

Data security is accomplished through the Management GUI. See “Locating Management

Gas and particulate exposure

Table 20. Gas and particulate exposure

Contamination Requirement

Gaseous contamination Severity level G1 as per ANSI/ISA 71.04-19851, which states that the reactivity rate of

copper coupons shall be less than 300 Angstroms per month (Å/month, ≈ 0.0039
µg/cm² - hour weight gain)2. In addition, the reactivity rate of silver coupons shall be
less than 300 Å/month (≈ 0.0035 µg/cm² - hour weight gain)3. The reactive monitoring
of gaseous corrosivity should be conducted approximately 5 cm (2 in.) in front of the
rack on the air inlet side at one-quarter and three-quarter frame height off the floor or
where the air velocity is much higher.

Particulate contamination Data centers must meet the cleanliness level of ISO 14644-1 class 8. For data centers

without airside economizer, the ISO 14644-1 class 8 cleanliness might be met by the
choice of the following filtration:

v The room air might be continuously filtered with MERV 8 filters.
v Air entering a data center might be filtered with MERV 11 or preferably MERV 13

filters.

For data centers with airside economizers, the choice of filters to achieve ISO class 8
cleanliness depends on the specific conditions present at that data center. The
deliquescent relative humidity of the particulate contamination should be more than
60% RH.34.Data centers must be free of zinc whiskers5.

Notes:

1. ANSI/ISA-S71.04. 1985. Environmental conditions for process measurement and control systems: Airborne contaminants,

Instrument Society of America, Research Triangle Park, NC, 1985.

2. The derivation of the equivalence between the rate of copper corrosion product thickness growth in Å/month

and the rate of weight gain assumes that Cu2S and Cu2O grow in equal proportions.

3. The derivation of the equivalence between the rate of silver corrosion product thickness growth in Å/month and

the rate of weight gain assumes that Ag2S is the only corrosion product.

4. The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust

absorbs enough water to become wet and promote ionic conduction.

5. Surface debris is randomly collected from 10 areas of the data center on a 1.5 cm diameter disk of sticky

electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope
reveals no zinc whiskers, the data center is considered free of zinc whiskers.

Figure 23. Types of receptacles

Network requirements

The library supports an independent customer network. It is the customer’s responsibility to provide the
proper length Ethernet cable for this connectivity.

The base module controller card has two Ethernet ports, which offer primary and redundant customer
network connectivity. See “Rear panel” on page 8.

These connections allow remote viewing and management of the library with the Management GUI.

Note: Have your network settings handy to use for entering on the Operator Panel. Your network
settings can also be stored as hardcopy on Appendix A, “Library Configuration Forms,” on page 137.

The secondary Ethernet port might be used for service. Three models are available for connection:
v No Ethernet port - Service personnel can connect a laptop to the customer network to use the

Management GUI with service login.

v Dedicated secondary Ethernet port - The secondary network port that is dedicated only for service

personnel to connect a laptop directly to the library.

30 Dell EMC ML3 Tape Library: User's Guide

v Secondary Ethernet port - The secondary network port can be disconnected and service personnel can

use it to connect a laptop directly to the library.

IP range selection

For internal communication between modules, the tape library uses an Ethernet connection with an
internal IP address range. To prevent any conflict between the internal IP address range and the external
IP addresses, you must select the internal IP range. Choosing the Internal IP address range, and also
entering the external IP address information is part of the initial setup of the library.

Host requirements

The library requires attachment to supported SAS or FC HBAs. See “Host connectivity” on page 20.

Static Sensitive

Risk of damage to devices
v A discharge of static electricity damages static-sensitive devices or

micro circuitry.

v Proper packaging and grounding techniques are necessary

precautions to prevent damage.

Follow these general guidelines.

v Check with a system administrator before the host computer is powered off.
v For a SAS library, confirm availability or install a SAS HBA that supports multiple LUNs.
v For a direct-attach Fibre Channel library, confirm availability of installation of an FC HBA.
v For connection of a Fibre Channel library through a compatible switch, verify that sufficient ports are

available.

Persistent binding to ensure SCSI ID assignment

When a server is booted, devices are discovered and assigned SCSI target and LUN IDs. It is possible for
these SCSI assignments to change between boots. Some operating systems do not guarantee that devices
are always allocated the same SCSI target ID after rebooting. Also, some software depends on this
association, so you do not want it to change. The issue of SCSI ID assignment is addressed by persistent
binding.

Persistent binding is an HBA function that allows a subset of discovered targets to be bound between a
server and device. Implemented by a worldwide node name (WWNN) or worldwide port name
(WWPN), persistent binding causes a tape drive's WWNN to be bound to a specific SCSI target ID. After
a configuration is set, it survives restarts and any hardware configuration changes because the
information is preserved. If a drive must be replaced, the new drive assumes the WWNN of the old drive
because the WWNN for the drive is location-dependent within the library. Because the WWNN does not
change, persistent binding does not need changing, thus preventing a potential outage.

Installing modules in a rack

Modules are easy to install in racks that are compliant to the EIA 310A Standard, when at least 1 meter
deep. You need a #2 Phillips screwdriver for this process.

Note: Install modules from the bottom to the top. Refer to “Structure and supported library
configurations” on page 2 for the correct configuration of Base and Expansion Modules.

To locate the rail locations when multiple modules are installed.

1. Locate the bottom of the lowest full U where the lowest module is installed.

2. Continue identifying the locations for any additional module 3U higher.

To install the rails into the rack, starting from the lowest rack location.
a. Locate the four universal rack connectors, four Philips screws, and two rackmount rails (LH and

RH).

Note: The universal rack connectors have two sides, for round hole and square hole racks. The
square-hole side might be painted.

Aligning and connecting modules

Skip this step if the library does not have Expansion Modules.

Aligning the modules ensures that the accessor can move freely between the modules. The library cannot
operate unless the alignment mechanisms of the upper modules are in the locked position, and the
alignment mechanism of the lowest module is unlocked.

46 Dell EMC ML3 Tape Library: User's Guide

1. From the front of the library, loosen the screws on each of the modules where they are attached to the
rails two full turns.

2. From the back of the library, starting with the bottom pair of modules, align each module with the
module below it. Repeat for each pair of modules. Refer to Figure 45.

a. Move the alignment lever of the upper of the pair of modules to the locked or engaged position. If

you encounter resistance, adjust the position of the upper module so the pin in the alignment
mechanism moves into the mating hole in the lower module.

service personnel for diagnostic and service procedures. Attach one end of the USB cable to your
notebook or other device and the other end to the front or rear USB port of the library.

Important: USB cable lengths of more than 3 meters are NOT supported for the front or rear USB ports.

Connecting Ethernet cables

To use the Management GUI, connect an Ethernet cable from the bottom Ethernet port on the Base
Module controller to your network. See “Rear panel” on page 8 for the location of the Ethernet ports.

Note: Ethernet port A (bottom Ethernet port) is the primary port. The second Ethernet port, Port B, is for
redundancy.

Powering on the library

1. Plug the power cables into the power connectors on each module and into power outlets.

Notes:

v The library has dual redundant power supplies. To increase redundancy, plug each power cord into

a different AC power circuit.

Installing 51

v A power supply is required in expansion modules if drives are installed.

2. Power on the library by pressing Power on the Base Module just below the Operator Panel and hold

for 5 seconds. See “Front panel” on page 7 for the location of the Power button. When the library is
powered on, it

a. Inventories the tape cartridges in the magazines,
b. Checks the firmware version on all modules,
c. Configures the tape drives.
d. Confirms the presence of the existing modules,
e. Searches for any new modules.
f. When the library is powered on for the first time, the Initial Setup starts. See “The Initial Setup

process.”

The Initial Setup process

When you turn on the library for the first time, the Initial Setup process starts automatically. Click Next
to start the process. The wizard guides you through setting the Internal IP range, setting library network
configuration, configuring date and time, and setting the administrator PIN. You can skip items and stop
the wizard at any time. After you configure the network settings, you can start the wizard from the
Management GUI to complete more configuration items.

Notes on navigation and entering data into the Operator Panel

v The arrow keys on the front panel are used to select numeric and alphanumeric characters and

symbols. Capital and lowercase letters, numbers, and punctuation are available to use.

v The right button under the arrows is Enter, which is pressed before you enter text.
v The left button under the arrows is Back/Return, which is used to delete entries.

See Figure 56 on page 62.

When the library starts up for the first time, the initial setup automatically begins.

1. Enter the IP address for your library. See “IP range selection” on page 31.

v Enabling or disabling Library Auto Clean. See “Methods of cleaning drives” on page 69.

Labeling and loading tape cartridges

The library can power on without cartridges, but needs cartridges before it can complete data read and
write operations, or any tests or operations that transfer cartridges.

Bar code labels are highly recommended in production environments to improve inventory time in the
library and ease cartridge-handling processes outside the library. See “Labeling tape cartridges” on page

145.

The I/O station

If the I/O station is enabled, you can use it to load cartridges into the library. Press the magazine button
for less than 3 seconds and after the button LED is flashing fast, pull out the I/O station.

Installing 53

Figure 53. Open I/O station seen from the left

Important: The lowest I/O slot of the lowest module in a library is inaccessible to the accessor, so the
I/O Station of the lowest module has four slots instead of 5.

Bulk loading magazines

1. Unlock the magazine by pressing the magazine button for more than 3 seconds, wait for the button to

flash fast and then pull out the magazine.
a. From the Operator Panel or Management GUI, select the module and then select Open Magazine.

You can also press the release button on the front panel of the module to release the magazine.

b. Wait until the magazine is unlocked, and then pull out the magazine.

Note: Wait for the Operator Panel/Management GUI message to say that the magazine is
unlocked before the magazine is pulled out.

54 Dell EMC ML3 Tape Library: User's Guide

Figure 54. Magazine pulled out

2. Load the tape cartridges into the magazine.

Important: The lowest slots of the lowest module in a library are inaccessible to the accessor, so do
not load cartridges into these cartridge slots.

3. Insert the magazine into the unit.

4. Push the magazine handle slowly until the magazine release latch snaps into place. The magazine

locks into place.

Important: Push the magazine fully into place until the latch snaps into place.

5. Repeat steps 1 - 3 for each of the other magazines.

See “Accessing cartridges” on page 70.

Verifying the installation

Verify that the library has the current firmware revision. The library firmware revision is displayed at
Library > Actions > Properties.

1. Verify library firmware and update if needed: Library > Actions > Update Library Firmware

2. Run Library Verify.

3. Save the configuration settings to a file on your computer from the Management GUI: Settings >

Library > Advanced > Save Configuration File.
Having a backup of the library configuration is helpful when the library is recovering from a

configuration error or needs service.

Advanced library configuration

To create and manage multiple logical libraries, utilize the advanced logical library function.

Installing 55

Overview

Multipath architecture

The multipath architecture feature of this tape library allows Open Systems applications to share the
robotics of the library. See “Library sharing” on page 17 for information.

The library features storage area network (SAN) ready multipath architecture. This architecture 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 multipath
architecture makes sharing possible by partitioning 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 if your application does not support the mixing of drive generations and media in the same
logical library.

The multipath architecture of this library is designed to provide the capability to share the library
robotics. The sharing is accomplished first by partitioning the library into multiple logical libraries (up to
the number of drives installed). Then, each logical library is assigned its own separate and distinct drives,
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 application that is using the drive and storage slots of one logical library, while a
UNIX application uses the drive and slots of another logical library. See “Mixed drives” on page 12.

Multiple logical libraries

A library can be partitioned into multiple logical libraries to enable simultaneous data backup and restore
tasks from different applications. For example, you can create multiple logical libraries so that is
processes

v Commands from Application 1 (about Department A) in Logical Library 1
v Commands from Application 2 (about Department B) in Logical Library 2
v Commands from Application 3 (about Department C) in Logical Library 3

In this configuration, the tape drives and cartridges of each logical library are dedicated to that library
and are not shared among other libraries and subsequently other applications. Commands that are issued
by the applications travel to the library through three unique control paths. So, the data processing for
Department A is confined to the tape drives and cartridges of Logical Library 1. Processing for
Department B is confined to the tape drives and cartridges of Logical Library 2, and so forth.

For applications that do not support mixed drive types and media within the same logical library,
partitioning the library into multiple logical libraries provides the capability to keep them separate. For
example, you can partition the following tape drives and their media into multiple and separate logical
libraries:

v LTO 8
v LTO 7
v LTO 6

Multiple control paths

With this tape library's multipath architecture, in addition to creating multiple logical libraries, you can
configure any logical library to have more than one control path. A control path is a logical path into the
library through which the library receives standard SCSI Medium Changer commands to control the library
operations.

56 Dell EMC ML3 Tape Library: User's Guide

Multiple control paths reduce the possibility of a failure in one control path to cause the entire library to
become unavailable. Also, when you configure more control paths, more library-sharing configurations
and options are possible. Access to the library is on a first-come, first-served basis. Each control path for a
logical library can accept commands while the library is in use by another control path.

Multiple control paths for control path failover

This tape library offers an optional control path failover feature. See “Library sharing” on page 17 and
“Path failover and load balancing” on page 18.

Use of the control path failover feature further reduces the possibility of a failure in one control path to
cause the entire library to become unavailable.

The control path failover feature (feature code 1682) enables the host device driver to resend a command
to a different control path for the same logical library.

Library partitioning

Libraries that contain at least two drives can configure two logical libraries. It is possible to configure up
to 21 logical libraries in the library (up to the number of drives installed). In a partitioned library, the
Operator Panel reports only the status of logical library 1 in the main menu because of space limitations.
The user must go to the logical libraries status in the Operator Panel to get the information about the
additional library partitions. The Management GUI provides a Logical Library Graphical View.

Partitioning of libraries

With full-height or half-height physical drives, physical numbering is bottom up for all drives. For
example, if you replace a half-height drive in Figure 22 on page 16, the drives are still numbered 1-4. If
you add a drive in any of the slots in between drives numbered 1 and 4, the physical numbering changes
and is still numbered bottom up.

Important: A full-height drive can be installed in a module in the lower two slots only.

Configuration of a 1-logical library system

A one logical library system contains all drives present in any drive positions, and it contains all the slots.

Configuration of multiple logical libraries

A library with multiple logical libraries must have a drive for each logical library and at least one slot.
Drives can be in any location in the library. It is best to have drives that are located near the slots that are
assigned to the same logical library to minimize accessor movement and maximize performance.

SCSI element-addressing

A logical library assigns SCSI element addresses to drives, storage slots, I/O slots, and the accessor. For
each element type (drive, storage, I/O), the SCSI element address can be viewed on the Management
GUI.

While SCSI addressing follows the same method as physical location-numbering, this action depends on
the Advanced Logical Library configuration.

Drive numbering is from bottom to top. Storage slot-numbering is from left magazine (front to back,
bottom to top) to right magazine (back to front, bottom to top). IO slot-numbering is from bottom to top.
Accessor is single number.

Installing 57

Note: When the number of drives in your library are reduced, update the logical library configuration.
This action removes all event notifications that indicate a drive is missing.

Updating the logical library configuration might change the SCSI element addressing.

Verifying the host connection

To verify the connections between the host computer and the library

1. Install the application software and drivers that are compatible with the library. Backup software

packages might require extra software or licensing to communicate with the robotics.

2. Verify the connection between the library and the host by using the host server’s operating system

utilities. Or, use the Tape Diagnostic Tool (ITDT) to verify the communication between library and
host. See “The ITDT firmware update, dump retrieval and drive test tool ” on page 77.

See “Host connectivity” on page 20 for compatible servers and software.

Methods of cleaning drives

Automatic cleaning of tape drives is disabled by default in the library. However, automatic cleaning of
tape drives is recommended for this library. It is also possible to initiate manual or host cleaning
methods.

The head of every tape drive in the tape library must be kept clean to prevent errors that are caused by
contamination. To help you keep the drives clean, Dell provides a cleaning cartridge with the library. The
library uses the cleaning cartridge to clean the drive with whatever cleaning method that you choose. In
all methods, cleaning is done after the data cartridge is unloaded from the drive and before the next load.

It is the operator’s responsibility to monitor cleaning cartridge usage and replace cleaning cartridges as
necessary. This tape library provides multiple ways to monitor and manage cleaning cartridges. If SNMP
traps are enabled, a trap is generated when a cleaning cartridge expires. It is also possible to use the
Management GUI to monitor the cleaning cycles that remain on a cleaning cartridge and to the enable a
setting that automatically ejects expired cleaning cartridges.

Three methods of cleaning are available.

Automatic cleaning

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.

Select Auto Clean to enable the auto cleaning feature. When enabled, the library automatically
initiates a cleaning operation when media is unloaded from a drive that requires cleaning instead
of creating a warning event when a drive requires cleaning. For reliable operation, enable Auto
Clean for each logical library and ensure that the library has a valid cleaning cartridge.

When a cleaning operation is initiated, the library first attempts to use an unexpired cleaning
cartridge from the same logical library as the tape drive. If the logical library does not contain an
unexpired cleaning cartridge, the library attempts to use an unexpired cleaning cartridge from a
storage slot that is not assigned to a logical library. The library does not use a cleaning cartridge
from a different logical library. When auto cleaning is enabled, ensure that each logical library has
an unexpired cleaning cartridge. Or, place at least one unexpired cleaning cartridge in a storage
slot that is not assigned to a logical library.

After the initial configuration, Auto Clean can be turned on or off by accessing the Logical
Library Wizard Expert Mode.

1. Go to Library > Logical Libraries > Actions > Manage Logical Library (Expert Mode).

2. Select the logical library, then click Edit.

3. Click Next to go to the General Settings screen.

4. Check or clear Auto Clean, then click Next on the subsequent screens.

5. If a change was made, click Finish and the Logical Libraries are reconfigured. If no changes

were made, click Cancel.

Managing 69

Note: Dell recommends enabling the Auto Clean function on the library. With the Auto Clean
function enabled, drive cleaning occurs automatically. The only time Auto Cleaning must be
disabled is when your backup application requires that it has control.

Manual cleaning

Manual cleaning requires that you select a menu option from the Management GUI to clean one
or more of the tape drives. Manual cleaning is always supported.

Host cleaning

Host cleaning enables the backup application to define and control the cleaning process.
Automatic and manual cleaning use the CLNxxx VOLSER.

Note: For tape cartridge information, see “Supported tape cartridges” on page 16.

Accessing cartridges

Each magazine has a button that provides an easy way to open a magazine. See “Front panel” on page 7.

Each module can be configured to have a portion of the right magazine that is designated as an I/O
station or this option can be disabled. To open the I/O station, press the magazine button for less than 3
seconds. To open the entire magazine, press the magazine button for more than 3 seconds.

Notes:

1. If a magazine is opened, no other magazines or I/O stations can be opened.

2. If during the magazine open process the magazine is not opened within 30 seconds, the magazine

locks.

3. The user must pull out the magazine, as the magazine does not eject.

The LED also provides an indicator of the current state of that magazine.
