Group Administration Data recovery
13–7
Figure 13-5 shows the final step in recovering data—fail back to the primary group. To fail back to the primary
group:
• Set the recovery volume offline.
• Replicate the recovery volume to synch
ron
ize volume data across both groups.
• Demote the recovery volume to an in
bound replica set.
• Promote the failback replica set to a volume.
Y
ou can perform these tasks separately, or use the Replicate to Primary operation, w
hich encompasses all the tasks.
At this point, the volume replication configuration returns to it
s original state and users can connect to the volume
on the primary group.

Promoting an inbound replica set to a recovery volume
To temporarily fail over a volume (or template or thin clone) to the secondary group, you promote the inbound
replica set to a recovery volume (or recovery template or recovery thin clone) and snapshots. Users can connect to
the recovery volume and resume access the volume data.
A recovery volume name is generated automatically, based on th
e volume name, with a dot-number extension (for
example,
vol01.1). You can chose to keep the same iSCSI target name as the original volume to facilitate iSCSI
initiator connections to the recovery volume.
