To move or unload cartridges
The ability to move cartridges is provided, but only to an empty Location (tape drive or numbered
slot).
•
Click on the
Move
button. There is a right-hand column,
Move Cartridge
. The
Move Cartridge
drop-down menu lists available empty slots. (Empty numbered slots are created if you delete
a cartridge.)
•
Use the
Unload all Cartridges
button to return all cartridges to their slots.
The move and unload options are unlikely to be required very often, but may be useful if the user
needs to re-align their library configuration against their backup application should they become
out of sync, perhaps because the backup application has crashed, or if the backup application
does not support the Move Medium command.
Emulation types for tape devices
HP StoreOnce Backup Systems emulate a range of physical tape devices, which are listed below.
•
D2DBS Generic Library:
This is a tape library device which allows you to configure up to 192
drives per node and up to 16384 cartridges per library.
If it is supported by your backup application, this is the preferred emulation type because it
does not emulate any physical library types in existence and is, therefore, clearly identifiable
as a StoreOnce device. It is the most flexible emulation type available; however, backup
application support varies by software vendor.
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.
NOTE:
Symantec prefer their customers to use this emulation type with BackupExec and
Netbackup.
•
MSL G3 series (2x24) Library:
This is a tape library device with a maximum of two embedded
Ultrium tape drives and 24 cartridge slots. It should be used when implementing rotation
schemes which involve simultaneous backup jobs to two devices. This emulation type is widely
supported by backup applications.
•
MSL G3 series (4x48) Library:
This is a tape library device with a maximum of four embedded
Ultrium tape drives and 48 cartridge slots. It should be used when implementing rotation
schemes which involve simultaneous backup jobs to more than two devices or those that use
a large number of cartridges devices. This emulation type is widely supported by backup
applications.
