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 (page 58) 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.
Why make target libraries visible?
There are two occasions when it may be useful to make a target library visible to the backup
application on the host.
• To confirm that replication is working correctly and check the integrity of the replicated backup
by doing a test restore
• To perform manual tape copy jobs to any tape device on the network using the backup
application
IMPORTANT: You cannot change data on a Target library cartridge; you may only load it
temporarily into a physical tape device to read it.
