• You cannot change the library type to a type that has a smaller set of maximum values (e.g. number of cartridges) than is currently set. 1. Select the device in the list to display its details and then click on Edit. 2. Amend details as appropriate and click Update to apply them. The information for the Interface Information tab is generated automatically and cannot be changed. To delete a device Select the required device and then click on Delete in the Details section to delete it. You will be prompted to confirm that this is what you wish to do. WARNING! All data on the device will be deleted. The library's deduplication store is also deleted. It may take up to 15 minutes to delete all the files and free space on the HP StoreOnce Backup System. Making Replication Target libraries visible to the host NOTE: See "Replication" on page 75 for more details on replication configuration. Replication Target libraries are not normally visible to the host, but you can configure devices to make them visible to backup applications. This allows the backup application to: • Move cartridges from storage slots to drives in the library • Perform SCSI commands on the library device • Perform read and verify operations on the cartridge (but not write) • Perform load/unload operations on the tape device WARNING! This facility should be used with care. If the backup application can see both source and target libraries, it will not be able to distinguish between the source library and the target library because the barcodes are duplicated in the two locations. 22 Virtual Tape Devices

Making Replication Target libraries visible to the host
NOTE:
See
“
Replication
”
on page 75 for more details on replication configuration.
Replication Target libraries are not normally visible to the host, but you can configure devices to make
them visible to backup applications. This allows the backup application to:
•
Move cartridges from storage slots to drives in the library
•
Perform SCSI commands on the library device
•
Perform read and verify operations on the cartridge (but not write)
•
Perform load/unload operations on the tape device
WARNING!
This facility should be used with care. If the backup application can see both source and target libraries,
it will not be able to distinguish between the source library and the target library because the barcodes
are duplicated in the two locations.
