Note: After you recover a partition, if you want to continue backing
up data to the partition, you must remap your backup
application to point to the target system instead of the source
system.
Performing a Failback For a Partition
Perform a failback of a VTL partition if a source system that was
previously unavailable becomes available again. When you failback a
partition, you select a received snapshot. The DXi4701 copies the
snapshot from the target system back to the source system. You can
then perform a recover operation to recreate the partition on the source
system just as it was at the point in time when the snapshot was saved.
Note: Before you can failback a partition, on the original source
system, you must add the original target system to the list of
allowed replication sources (see Adding a Replication Source
on page 258). This is because, during failback, the original
target is acting as a source when it sends a snapshot to the
original source.
To perform a partition failback:
1 On the target system, select a snapshot in the Snapshots List and
click Failback .
The Failback Target page displays (see Figure 82 ).
