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.

Total No of Cartridge

Slots:

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

Number of drives:

and drives that a host can physically access. (64 for iSCSI interfaces and 128 for FC

interfaces.)

Data deduplication is enabled by default for the library device. It is not possible to disable

deduplication on any HP StoreOnce G2 Backup System.

Deduplication:

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

Port:

embedded tape drives. The choices in the drop-down menu depend upon your network

configuration. There are up to two iSCSI ports (this depends upon your network mode), and

two FC ports if you have the FC model. FC users may choose to connect the device to an

iSCSI or a FC port. It is possible to change the tape device ports after creation.

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

No of Barcode

Characters:

the user selects 6–character barcodes this is not reflected on the Web Management Interface,

which will still show 8–character barcodes. However, when a backup application runs an

inventory command it will only see 6–character barcodes.

This option allows you to specify which six characters are reported to the backup application

when using 6–character barcodes. The six characters that are reported to the backup

Barcode Justification:

application are determined by whether the justify option is set to left or right. Setting it to

left justify will mean that the first 6 characters of the barcode will be reported to the backup

application, right justify will report the last 6 characters. Note that using left justify may result

in the backup application seeing barcodes that appear to be duplicates.

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

iSCSI Initiator Name:

(iSCSI devices only)

a host for a first 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 find the name by running

the iSCSI Initiator on the host and copying the Initiator Node Name from the General tab.
