This is the name that is used to identify that library. You may like to enter a name that
identifies the host or backup job with which it is associated.
This is the emulation type used by the backup software. The HP B6000 Backup System
supports a number of emulation types, the default is D2DBS Generic, see also
types for tape device (page
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.
By selecting a drive emulation type, HP LTO–2, 3, 4 or 5, 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, LTO-5 = 1.6 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.
If you have selected D2DBS Generic for the Library Emulation Type, you will be able to
select Ultrium VT for the drive emulation. This is a generic Ultrium device which is clearly
identifiable as virtual. Backup application support for Ultrium VT is reasonable, but not quite
as complete as the D2DBS library type, so its not possible to use it with all backup software.
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 automatically populated with a new cartridge upon creation 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.
The default number of drives is determined by the Emulation Type that you have selected. If
you increase the number of drives be careful not to exceed the maximum number of libraries
and drives that a host can physically access. (128 for FC interfaces.) As long as the Port
configuration is the default FC Port 1&2, drives are automatically distributed evenly across
both ports. If you increase the number of drives, the additional drives will also be distributed
evenly across the ports.
Data deduplication is enabled by default for the library device. It is not possible to disable
deduplication on any HP B6000 Backup System.
This is the date that the library was created and is generated automatically.
This identifies the network port on the HP StoreOnce Backup System to which the device is
connected. This will be the port used for the Library device as well as the default port for
embedded tape drives. There are two FC ports in the drop-down menu, as well as the option
to select both. The default configuration bonds FC Port 1 & 2, which automatically distributes
drives evenly across both ports to ensure best performance and failover. It is possible to
change the tape device ports after creation, but you may also need to edit the port-drive
configuration manually.
The HP StoreOnce Backup System generates barcodes automatically for cartridges. This
option allows you to select whether the barcodes should have six or eight characters. When
the user selects 6–character barcodes this is not reflected on the Web Management Interface,
27). The emulation type determines how many embedded drives
