Moving a failback replica set to a different storage pool
You can move a failback replica set to a different pool in the primary group. If you later promote the failback
replica set to a volume, the volume belongs to the new pool.
1. On the primary group, click
Replication, expand the replication partner, expand Inbound Replicas,
select the failback replica set, and click
Change storage pool.
2. Select the new pool and click
OK.
Failing back to the primary group
When you want to return to the original volume replication configuration, you can use the Failback to Primary
operation.
Recommendation: De
ll recommends that you use the Replicate to Partner operation before failing back to the
primary group. Although the Failback to Primary operation performs a final replication, the
recovery volume is offline during the final replication. See Replicating a recovery volume to
the primary group.
Restriction: Y
o
u cannot fail back a template volume.
Restriction: The Failback to Primary operation is
available only if the primary group and the secondary group are
running PS Series Firmware Version 4.0 or greater. If you do not meet this requirement, you must
perform the steps individually, as described in Manually performing the failback to primary operation
on
page 13-16.
1. Obtain the name and password for a group administrator account on the primary group.
2. Click
Volumes, then expand Volumes, then select the recovery volume, and then click Failback to
primary.
3. Confirm that you want to set the recovery volume offline.
4. In the Failback Recovery Volume dialog box:
• Specify the group administrator account name and password.
• Select whether to perform the replication by
using manual transfer replication.
See About manual transfer
replication on page 1
2-3.
• Select whether to save the primary gr
oup administrator account name and password for future use in the
current GUI session.
Then, click
OK.
As part of the failback operation, a replica is created immediately on the secondary group
to reestablish the failback
snapshot (and set the failback baseline). Because the volume data is already synchronized between the groups, no
data is actually transferred.
To monitor the Failback to Primary operation and
make sure all tasks complete, open the Alarms panel at the
bottom of the GUI window and click the
Failback Operations tab. If an individual task fails, you must correct
the problem and then retry the task. See Handling a failed operation on page 1
3-15.
