Acclimation
Server and storage equipment (racks and frames) must be gradually acclimated to the surrounding
environment to prevent condensation.
When server and storage equipment (racks and frames) is shipped in a climate where the outside
temperature is below the dew point of the destination (indoor location), there’s a possibility that water
condensation can form on the cooler inside and outside surfaces of the equipment when the equipment is
brought indoors.
Sufcient time must be allowed for the shipped equipment to gradually reach thermal equilibrium with
the indoor environment before you remove the shipping bag and energize the equipment. Follow these
guidelines to properly acclimate your equipment:
• Leave the system in the shipping bag. If the installation or staging environment allows it, leave the
product in the full package to minimize condensation on or within the equipment.
• Allow the packaged product to acclimate for 24 hours.1 if there are visible signs of condensation (either
external or internal to the product) after 24 hours, acclimate the system without the shipping bag for an
extra 12 - 24 hours or until no visible condensation remains.
• Acclimate the product away from perforated tiles or other direct sources of forced air convection to
minimize excessive condensation on or within the equipment.
1
Unless otherwise stated by product-specic installation instructions.
Note: Condensation is a normal occurrence, especially when you ship equipment in cold-weather
climates. All Dell products are tested and veried to withstand condensation that is produced under these
circumstances. When sufcient time is provided to allow the hardware to gradually acclimate to the
indoor environment, there should be no issues with long-term reliability of the product.

– For AC powered racks, be sure to disconnect all power cords in the rack cabinet when directed to
disconnect power during servicing.
– For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls the
power to the system unit(s), or disconnect the customer’s DC power source, when directed to
disconnect power during servicing.
• Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do
not plug a power cord from a device installed in one rack cabinet into a power device installed in a
different rack cabinet.
• An electrical outlet that is not correctly wired could 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. (R001 part 1 of 2)
Caution
• Do not install a unit in a rack where the internal rack ambient temperatures might exceed the
manufacturer's recommended ambient temperature for all your rack-mounted devices.
• 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.
• 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.
• (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.
Safety and environmental notices
xxvii
• (For xed drawers) This drawer is a xed drawer and must not be moved for servicing unless specied
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. (R001 part 2 of 2)
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:
• 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 conguration of the rack cabinet as you received it. If this
conguration is not known, you must do the following:
– 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.
– 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
conguration specically allowed it.
• If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the
suite.
• If the rack cabinet you are relocating was supplied with removable outriggers, they must be reinstalled
before the cabinet is relocated.
• Inspect the route that you plan to take to eliminate potential hazards.
• 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.
• Verify that all door openings are at least 760 x 2032 mm (30 x 80 in.).
• Ensure that all devices, shelves, drawers, doors, and cables are secure.
• Ensure that the four leveling pads are raised to their highest position.
• Ensure that no stabilizer bracket is installed on the rack cabinet during movement.
• Do not use a ramp that is inclined at more than 10 degrees.
• When the rack cabinet is in the new location, complete these steps.
– Lower the four leveling pads.
– Install stabilizer brackets on the rack cabinet or in an earthquake environment bolt the rack to the
floor.
– If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest
position to the highest position.

• The robotic assembly has ngers that enable it to grab tape cartridges and move them to and from the
I/O station, storage slots, and drives.
• The spooling mechanism has a cable that extracts and retracts based on movement of the robotic
assembly. This cable provides communication between the robotic assembly and the library main
board.
• 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 rmware 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 160.
Note: For libraries with S/N 7800K0K and higher, review the “Minimum rmware levels for common
library features” on page iii.
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.

User interfaces
This library has two user interfaces: the Management GUI and the Operator Panel.
• “The Management GUI” on page 59 - With the Management GUI, you can monitor, congure, 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
“Network connectivity” on page 21.
• “The Operator Panel” on page 62 - With the Operator Panel, you can monitor, congure, and control
the library from the front panel. Functions are limited to those applicable to being in front of the library.
Supported tape drives
The library supports LTO6 and later tape drives. Each drive requires a SAS or Fibre Channel cable.
For minimum and maximum storage congurations, see Table 3 on page 2. For minimum rmware levels,
see “Minimum rmware levels for common library features” on page iii.

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 that are sent by a server to control a
specic 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.
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 on page 13
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 and logical location.
The library assigns each tape drive a unique address to indicate its physical location, which is shown in
Figure 22 on page 15. The physical numbering is bottom up on all drives. This information is shown on
the Drives page of the Management GUI.
Figure 22. Physical numbering of drives
The library assigns each tape drive a SCSI element address that consists of a value that denes 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.
Chapter 1. Overview

Within the library, the supported LTO tape drives use the following cartridge types:
• LTO8 Data Cartridge
• LTO8 WORM Data Cartridge
• LTO M8 Data Cartridge
• LTO7 Data Cartridge
• LTO7 WORM Data Cartridge
• LTO6 Data Cartridge
• LTO6 WORM Data Cartridge
• LTO5 Data Cartridge
• LTO5 WORM Data Cartridge
• LTO4 Data Cartridge
• LTO4 WORM Data Cartridge

For information, see Appendix C, “LTO media,” on page 157.
Library functions
The library provides many specic functions, such as random or sequential operating mode, encryption,
library sharing, path failover, and alerts and logging.
Random and Sequential Logical Library modes
A Logical Library can be congured in one of two modes: Random and Sequential.
Random Mode
Random Mode is intended to be used by host applications that support SCSI media changer devices.
Random Mode is the default.
In Random mode,
• The host application chooses the cartridges that are moved to the drive.
• I/O slots provide the flexibility for the user to add and remove cartridges and the host application is
automatically notied of these changes.
• Multiple drives can be assigned to provide parallel processing data operations and redundancy in case
of failure.
Sequential Mode
Sequential Mode is intended to be used by host applications that aren’t supporting SCSI media changer
devices but need to get another cartridge loaded if the current cartridge is full.
In Sequential Mode,
• The library predenes the sequential order that the cartridges are moved to the drive.
• I/O slots are hidden as they aren’t assignable to a logical library with sequential mode enabled.
• Only one drive can be assigned to a logical library with sequential mode enabled.
• There’s no control path drive and no media changer device is congured to the host server.
Options to consider when Sequential Mode is chosen:
16
Dell EMC ML3 Tape Library: User's Guide
• Basic Function - To initiate use of cartridges, the user issues a Move Cartridge command to the drive
through the Management GUI. After the load, the host application can begin data I/O activity. When the
host application unloads the drive, the library moves the next cartridge into the drive. This behavior is
implicit, unless otherwise dened by selection of another option.
• Loop Option - If a move sequence ends because no more cartridges are available in the current logical
library, the sequence starts again by loading the rst cartridge of the logical library. This option can be
chosen with or without the Autoload function.
• Autoload Option - If enabled, the library loads the rst cartridge of the logical library to the Sequential
Mode tape drive during library startup after inventory scan is nished. This option changes the implicit
behavior of the Basic function. This option can be chosen with or without the Loop option.
If storage slots are congured to I/O slots after assignment to a Sequential Mode logical library, they are
still considered valid available slots and are used for movements. This option stays until you run the
expert wizard again, and then these I/O slots no longer appear in the list of available slots. Finishing the
expert wizard then sets the new slot assignment and these I/O slots can no longer be used for
movements.
To enable sequential mode, click the Enable Sequential Mode check box in the Basic Logical Library
Wizard or Expert Logical Library Wizard.
Encryption
All supported tape drives in this library support encryption.
The encryption enabled drive contains the necessary hardware and rmware 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 certicate is installed at manufacturing time. Each drive receives a unique serial
number and certicate. The T10 application might validate each drive instance by checking the drive's
digital certicate.
The library provides these options.
1. Encryption disabled
2. Application Managed Encryption (AME)
3. Library Managed Encryption (LME). LME is a built-in feature. For conguration details, see
“Conguring Library Managed Encryption” on page 72
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 rmware to the current versions. The rmware 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. Congure 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. Congure 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 congured or reveried 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.
.
Chapter 1. Overview
17
Library sharing
The library can be congured 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 conguration.
1. A quick conguration for a simple one logical library conguration
2. An advanced conguration action for a multiple logical library conguration
Note: When any number of drives are loaded, a warning message appears when the Manage Logical
Library (Expert Mode) wizard is accessed.
The second method gives the ability to create congurations 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
conguration” on page 56.
Control path failover, Data 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 efciently. 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 eld 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 congured 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 congured, 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 14 on page 19
Table 14 on page 19 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.
• 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 105.
• Email (SMTP - Simple Mail Transfer Protocol) Notications: The library can congure email
notication of library events. The library must have network access to an SMTP server. See “Locating
Management functions” on page 63.
• Remote Logging (rsyslog): The library can send syslog (system log) notications to a congured remote
(rsyslog) server. When system events occur, the ML3 tape library creates a log of these events. With this
notication feature congured, the library sends a notication 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.
• 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 notications when they receive an SNMP alert.
See the manual for your network management application.
Chapter 1. Overview
19
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-todate library Management Information Base (MIB). The SNMP server's MIB contains units of information
that specically describe an aspect of a system, such as the system name, hardware number, or
communications conguration.
SNMP Notication Levels
SNMP provides various levels of notication about specic library events and user actions.
– Inactive – No events are sent.
– Critical – Only critical events are sent.
– + Warnings – Only critical and warning events are sent.
– + Conguration – Only critical, warning, and conguration events are sent.
– + Information – All events are sent.
Simple Network Management Protocol (SNMP) audit logging provides logging information about specic
tape library user actions. To congure SNMP, see “Locating Management functions” on page 63.
Host connectivity
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.
Compatible servers and software
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.
• 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, rmware revisions, and adapter cards.
Note: Dependent on the use of Random or Sequential Mode, the library might require 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. See
“Random and Sequential Logical Library modes” on page 16.
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.

Dell EMC ML3 Tape Library: User's Guide
Network connectivity
This library supports various browsers and interfaces.
Supported browsers
Dell supports higher versions of the browsers if the vendors don’t remove or disable functions that the
product relies upon. For browser levels higher than the versions that are certied with the product,
customer support accepts usage-related and defect-related service requests. As with operating system
and virtualization environments, if Dell support can’t re-create the issue in the lab, the client might be
asked to re-create the problem on a certied browser version to determine whether a product defect
exists. Defects aren’t accepted for cosmetic differences between browsers or browser versions that don’t
affect the functional behavior of the product. If a problem is identied in the product, defects are
accepted. If a problem is identied with the browser, Dell might investigate potential solutions or
workarounds that the client can implement until a permanent solution becomes available.
Supported interfaces
This tape library supports the Gigabit Ethernet interface in either auto negotiation or xed modes of 10
Mbps, 100 Mbps, and 1 Gbps by using half or full duplex. The library supports the following TCP/IP
protocols:
IPv4 and IPv6 support
This tape library supports Internet Protocol (IP) addresses in both IPv4 and IPv6 format. Both the
integrated management console (IMC) and the management GUI allow the denition of IPv4 and IPv6
addresses. The key proxy determines the IP version that is used and presents the correct IP address
and parameters to the IP Stack.
Simple Network Management Protocol (SNMP)
SNMP traps are supported for drive and library events. SNMP management query functions are
supported by using a standard Management Information Block (MIB).
Hyper Text Transfer Protocol (HTTP)
An embedded web server provides a management GUI for library management and query capabilities.
Secure Socket Layer (SSL)
The tape library supports SSL, a protocol for transmitting private documents through the internet.
Key Management Interoperability Protocol (KMIP)
Used for communicating with the IBM® Security Lifecycle Key Manager and other security key
management software.
Simple Mail Transfer Protocol (SMTP)
The tape library supports SMTP for sending email alerts.
Network Time Protocol (NTP)
The tape library supports NTP for external time-and-date synchronization.
Lightweight Directory Access Protocol (LDAP)
The tape library supports LDAP for centralized authentication.
Domain Name System (DNS)
The tape library supports DNS for flexible IP addressing.
Dynamic Host Conguration Protocol (DHCP)
The library supports DHCP for automatically providing an Internet Protocol (IP) host with its IP
address and other related conguration information, such as the subnet mask and default gateway.
Chapter 1. Overview

Chapter 2. Planning
The library requires an environment able to accommodate the appropriate space, power, location, and
other technical specications. 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 Conguration Forms,” on page 146.
Library Layout and Location requirements
Information for planning the installation and layout of your library, including various specications for
optimal performance.
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 congurations” 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’re determining where to locate your
tape library.
Library location
You’re 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’re 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 functions”
on page 63.

microscope reveals no zinc whiskers, the data center is considered free of zinc whiskers.
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 ltration:
• The room air might be continuously ltered with MERV 8 lters.
• Air entering a data center might be ltered with MERV 11 or preferably MERV 13
lters.
For data centers with airside economizers, the choice of lters to achieve ISO class 8
cleanliness depends on the specic 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.

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 Conguration Forms,” on page 146.
The secondary Ethernet port might be used for service. Three models are available for connection:
• No Ethernet port - Service personnel can connect a laptop to the customer network to use the
Management GUI.
• Dedicated secondary Ethernet port - The secondary network port that is dedicated only for service
personnel to connect a laptop directly to the library.
• 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.
The library requires attachment to supported SAS or FC HBAs. See “Host connectivity” on page 20.
Follow these general guidelines.
• Check with a system administrator before the host computer is powered off.
• For a SAS library, conrm availability or install a SAS HBA that supports multiple LUNs.
• For a direct-attach Fibre Channel library, conrm availability of installation of an FC HBA.
• For connection of a Fibre Channel library through a compatible switch, verify that sufcient 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
Static Sensitive
Risk of damage to devices
• A discharge of static electricity damages static-sensitive
devices or micro circuitry.
• Proper packaging and grounding techniques are necessary
precautions to prevent damage.
32
Dell EMC ML3 Tape Library: User's Guide
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 specic SCSI target ID. After a
conguration is set, it survives restarts and any hardware conguration 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.

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
160.
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.

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 71.
Verifying the installation
Verify that the library has the current rmware revision, and save the conguration settings. This action
can be helpful if the library requires service.
Verify that the library has the current rmware revision. The library rmware revision is displayed at
Library > Actions > Properties.
1. Verify library rmware and update if needed: Library > Actions > Update Library Firmware
2. Run Library Verify.
3. Save the conguration settings to a le on your computer from the Management GUI: Settings >
Library > Advanced > Save Conguration File.
Having a backup of the library conguration is helpful when the library is recovering from a
conguration error or needs service.
Advanced library conguration
To create and manage multiple logical libraries, utilize the advanced logical library function.
Overview
Overview of advanced features such as multipath architecture, multiple logical libraries, and multiple
control paths.
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 18
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 rst 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 rst-come-rst-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
56
Dell EMC ML3 Tape Library: User's Guide
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
• Commands from Application 1 (about Department A) in Logical Library 1
• Commands from Application 2 (about Department B) in Logical Library 2
• Commands from Application 3 (about Department C) using Sequential Mode in Logical Library 3
In this conguration, the tape drives and cartridges of each logical library are dedicated to that library and
are not shared among other libraries and applications. Commands that are issued by the applications
travel to the library through unique control paths or sequential mode processing by the library. So, the
data processing for Department A is conned to the tape drives and cartridges of Logical Library 1.
Processing for Department B is conned 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:
• LTO 8
• LTO 7
• LTO 6
Multiple control paths
With this tape library's multipath architecture, in addition to creating multiple logical libraries, you can
congure 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.
Note: No SCSI Medium Changer is congured when the logical library is enabled as Sequential Mode
Multiple control paths reduce the possibility of a failure in one control path to cause the entire library to
become unavailable. Also, when you congure more control paths, more library-sharing congurations
and options are possible. Access to the library is on a rst-come, rst-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 18
“Control path failover, Data 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 congure two logical libraries. It is possible to congure 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.
and
Chapter 3. Installing
57
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 15, 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.
Conguration 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.
Conguration of multiple logical libraries
A library with multiple logical libraries must have a drive for each logical library and at least ve slots.
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 conguration.
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.
Note: When the number of drives in your library are reduced, update the logical library conguration. This
action removes all event notications that indicate a drive is missing.
Updating the logical library conguration might change the SCSI element addressing.
Verifying the host connection
Procedure to verify the connection between the host computer and the library.
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 rmware update, dump retrieval and drive test tool ” on page 80.
See “Host connectivity” on page 20 for compatible servers and software.

Chapter 4. Managing
Four user roles are described, and each user role has its specic functions.
• Administrator - This role provides access to the administrator functions on the Management GUI.
There is a default administrator password adm001 for the rst login. The administrator password can be
changed on the Local Users page.
• Monitor - This role allows access to library status information and does not allow access to
conguration, maintenance, or operation features. Setting a monitor password restricts access to status
information to only those users who know the monitor password. Passwords for the Monitor role can be
set or changed by the administrator.
• Superuser - This role has same access rights as the Administrator role, except the ability to access the
Local Users and Remote Authentication (LDAP Authentication and Kerberos Authentication) pages.
In addition, it is possible to do cartridge moves and open magazines and I/O Stations. Passwords for the
Superuser role can be set or changed by the administrator.
• Service - This role provides access to the service functions on the Management GUI. Passwords for the
Service role can be set or changed by the administrator.
Notes:
• Monitor, Superuser, and Service user IDs must be enabled by the library administrator. These accounts
are disabled by default.
• For a complete description of the menu items available to each user role, see Appendix B,
“Management GUI functions and roles ,” on page 151.
The Management GUI
With the Management graphical user interface (GUI), you can monitor, congure, and operate most library
functions from a web browser.
When possible, use the Management GUI as the primary library interface. The web interface provides
access to more features, includes online help, and is intuitive to use.
Before the Management GUI can be used, you need to log in and congure the library network settings
with the Operator Panel. This action can be done during Initial Setup. See “The Initial Setup process” on
page 53.
Logging in with the Management GUI
1. Open a supported web browser and enter the IP address of the library in the browser’s address bar.
2. Type in the username (administrator or other administrator-created user) and the password. Click
Login.
Note: For initial login, type administrator and the password adm001. You must change the
password after the initial login. Your new password must have these characteristics:
• 8 characters long
• At least one lowercase alphabet character
• At least one uppercase alphabet character
• At least one numeric character
• No more than two consecutive characters
Note: Only one person (on Operator Panel or Management GUI) can be logged in to the library at a time. If
another person is already logged in when you try to log in, a dialog box appears asking if you want to log
off the other user.
