Description
Field
The name used to identify a particular library. Enter a name that identifies the host or backup
job with which it is associated.
Library Name
The emulation type of the library. The HP StoreOnce Backup system supports a number of
emulation types. The default varies according to product model.. See also
Emulation Type
. The emulation type determines the available embedded drives
and cartridge slots. For example, if you select HP MSL G3 Series (2x24), the device emulates
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 information about
device types they support.
The drive emulation type, HP LTO–2, 3, 4, 5 or 6, determines the default capacity of the
cartridges within the library device and the iSCSI inquiry string information provided to the
Drive emulation
backup application. Tape cartridge capacities can be increased at any time (but not
decreased), as long as the cartridge is blank, regardless of the drive emulation generation
number.
If you selected D2DBS Generic for the Library Emulation Type, Ultrium VT is an option for
drive emulation. This is a generic Ultrium device which is clearly identifiable as virtual.
Where supported by the backup application, HP recommends that D2DBS Generic and
Ultrium VT are used in preference to the other emulation types.
All drives on a library configured with the IBM-TS3500 emulation type will use the IBM-LTO3
drive emulation type. If the library is then changed to a different emulation type, the drives
will change to the new emulation type.
If you edit this field, the new setting applies only to the next drives that are created within
the library, it is not retrospectively applied to existing drives.
Define the number of cartridge slots in the library. The number of slots available depends
upon the Emulation Type selected. Each slot is automatically populated with a new cartridge
upon creation. The cartridge capacity corresponds to the Drive Emulation type.
Total Number of
Cartridge Slots
You can change the maximum size of the cartridge as long as it is blank. This means that
the value can only be changed after the device is created and before it is accessed by the
backup application.
The default number of drives is determined by the Emulation Type selected. If increasing the
number of drives, DO NOT exceed the maximum number of libraries and drives that a host
Number of Drives
can physically access: see
StoreOnce key parameters (page 183)
. The number of drives can
only be edited during library creation from this field. After library creation, there is a separate
button to Add/Remove drives.
Enables deduplication if the check box is selected (default); unselect to create a
non-deduplication library. Deduplication cannot be enabled or disabled once the library is
created.
