Note: If you chose to use manual transfer replication, the status of the create replica task is in-progress until
you complete the manual transfer replication. When the manual transfer replication is complete, the
Failback to Primary operation continues automatically.
When the Failback to Primary operation completes, on the seco
ndary group, the recovery volume disappears from
the list of volumes, and the inbound replica set reappears in the list of inbound replica sets. On the primary group,
the failback replica set disappears from the list of inbound replica sets, and the volume reappears in the list of
volumes.
Making a temporary volume available on the secondary group
You can make a temporary copy of a volume available on the secondary group, while providing continuous access
to the original volume on the primary group. This is helpful when you want to perform an operation, such as a
backup, on the copy, with no disruption to users. When the operation completes, you can resume replicating the
volume.
Note: This proce
d
ure assumes that the volume does not change while available on the secondary group, or—if the
volume changes—those changes are not replicated to the primary group. If you want to replicate changes,
follow the procedure described in Failing over and failing back a volume.
1. Promote the replica set to a recovery volume. See Pr
omoting an inbound replica set to a recovery volume.
Make sure you select the option that enables you to demote
the recovery volume.
2. Perform the desired operation on the recovery volume. See Recovery volume restrictions on
page 13-9.
3. Demote the recovery volume to an
inbound replica set:
Click
Volumes, then expand Volumes, then select the recovery volume, and then click Demote to replica
set
.
At this point, you can resume replicating the volume.
Permanently switching partner roles
You can switch the partner roles in a volume replication configuration. The original secondary group becomes the
new primary group, and the original primary group becomes the new secondary group.
Note: Because you cannot permanently demote a template volume
, when you switch roles for a replication
configuration that includes a template volume with thin clone volumes, only the thin clone replication
configuration switches. Therefore, the original template volume must still exist on the original primary
group after the switch, because the new thin clone replica sets depend on the template volume.
1. On the primary group:
a. Make sure the volume replication
configura
tion includes keeping the failback snapshot. See Modifying
volume replication configuration settings on
page 12-26.
b. Set the volume offline. See Setting a volume offline or online on page 9
-13.
c. Perform a final replication. This synchr
onizes volume data across the primary group and the secondary
group. See Creating a replica on p
age 12-28.
