2. Enter the appropriate details in the Libraries tab and click Create. There is also a tab to enable
and configure iSCSI Authentication, if this is required. Any information you enter on this tab must
match the information that you have configured in the iSCSI Initiator itself. (See also
“Device parameters” on page 114 below.)

This is the name that is used to identify that device. You may like to enter a
name that identifies the host or backup job with which it is associated.
Library Name
This is the emulation type used by the backup software. The HP D2D supports
the following emulation types: HP 1x8 G2 Autoloader (1x8), HP MSL Library
(2x24), HP MSL Library (4x24). and HP D2DBS Library (4x48).
The emulation type determines how many embedded drives and cartridge
slots are available. For example, if you select HP MSL G3 Series (2x24), the
device will emulate an MSL 2024 Library with two embedded tape drives
and a possible total of 24 cartridge slots. Consult your backup application
technical support information for further details.
Emulation Type
By selecting a drive emulation type, HP LTO–2, 3 or 4, you set only the
default capacity of the cartridges within the library device. (LTO-2 = 200
GB, LTO-3 = 400 GB, LTO-4 = 800 GB.) It does not affect the ability of the
backup application to write to the device and tape cartridge capacities can
be increased at any time (but not decreased), as long as the cartridge is
blank, regardless of the drive generation number, see “To edit maximum
cartridge size” on page 119.
Drive Emulation
This is where you define the number of slots that you require for your tape
rotation strategy. The number of slots available depends upon the Emulation
Type that you have selected. Each slot will be assigned a cartridge whose
capacity is appropriate to the Drive Emulation type.
You can change the maximum size of the cartridge as long as it is blank.
This means that you can only change the value immediately after the device
is created and before it has been accessed by the backup application. See
“To edit maximum cartridge size” on page 119.
Total No of Cartridge Slots:
The number of drives is determined by the Emulation Type that you have
selected.

Data deduplication is enabled by default for the library device. If you disable
this checkbox, you switch off deduplication for all data that is written to the
device. Compression will also be disabled and replication, if licensed.
