The snapshot is sent to the source system.
5 On the source system, in the Snapshots List , select the snapshot
that was sent during the failback operation and click Recover .
The Recovered Partition Name page displays (see Figure 81 ).
6 (Optional) In the Recovered Partition Name box, type a new name
for the recovered partition. (The default name is the original
partition name.)
7 Click Apply .
The partition and its cartridges are recovered on the source system. All
data stored on the partition at the time the snapshot was saved is
available.
After recovering the partition, you must add tape drives and a robot to
the partition, and you must map the devices before the VTL partition is
accessible. If the partition contains media, you will only be able to select
the highest capacity tape drive for that media type. For example, if the
partition contains SDLT600 tape cartridges, you will only be able to
select DLT-S4 tape drives when mapping devices to the recovered
partition.
Note: When a VTL partition is recovered on a target system, a new
serial number is created for the partition.
Note: If you previously remapped your backup application to a
recovered partition on the target system, after you failback the
partition, you must remap your backup application again to
point to the source system.
Deleting a Snapshot
Delete a snapshot if it is no longer needed. After you delete a snapshot,
it can no longer be used to recover or failback a VTL partition.
Note: You cannot delete a snapshot if a failback operation is in
progress for the snapshot. Wait for the failback operation to
complete, or abort the operation (see Failback Jobs on
page 155).
