Emulation Type
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 number of embedded drives is always 1, but the emulation type determines
how many cartridge slots are available. The default of 1x8 G2 Autoloader is
correct for most applications. This is a single Ultrium tape drive autoloader, with a
maximum of 24 cartridge slots. It should be used for simple rotation schemes where
a single backup job is to run at a time. This emulation type is widely supported by
backup applications. Consult your backup application technical support information
for further details.
Drive Emulation
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 96.
Total No of Cartridge
Slots:
This is where you de fi ne 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 96.
Number of drives: The number of drives is always 1.
Deduplication:
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.
Port:
This identi fi es the network port on the HP D2D to which the device is connected.
The choices in the drop-down menu depend upon your network con fi guration. There
are up to two iSCSI ports (this depends upon your network mode, see “ Network
Parameters ” on page 99).
See also “ Supported network con fi gurations ” on page 32.
iSCSI Initiator Name:
This is the Initiator Node Name of the host that will back up to this device. It
is provided automatically for the default library that is created when you run the
Installation wizard on a host for a fi rst time. But you must enter it manually if you are
creating a new device on this page. If you are using the Microsoft iSCSI Initiator, you
can fi nd the name by running the iSCSI Initiator on the host and copying the Initiator
Node Name from the General tab. See “ Manual driver installation ” on page 45.
World Wide Names tab
Device Name
This is the device name, such as Medium Changer or Drive 1.
Device Serial Number This is a unique serial number for the device. It is generated automatically by the
HP D2D and cannot be edited.
World Wide Node
Name
This is provided during manufacturing for all possible devices.
iSCSI Authentication tab
Require initiator to
logon
Check this box if you require the initiator to logon. You must also provide the
Initiator CHAP user name and secret.
Initiator CHAP User
Name
This should be the same CHAP user name that you con fi gure for the target on
the iSCSI Initiator. (On the Microsoft iSCSI Initiator, this is the User Name as it is
con fi gured on the Targets tab in the Log On to Target Advanced Settings.)
Initiator CHAP Secret
This should be the same CHAP secret that you con fi gure for the target on the iSCSI
Initiator. (On the Microsoft iSCSI Initiator, this is the Target Secret as it is con fi gured
on the Targets tab in the Log On to Target Advanced Settings.)
