Failback and restore Page 521 of 677
Restoring then failing back applications configured for DNS
failover
For application workloads that were configured for DNS failover, you can use the
Application Manager to initiate failback and, if desired restore data from the target back
to the source. In order to minimize downtime, the restoration process is completed before
the failback.
1. If you are using a cluster environment and protecting Exchange, make sure the
Physical Disk resource(s) and the IP Address resource are online on the source
cluster.
Exchange Note: When you bring the source cluster online, an identical network
name will be active on the target. Therefore, when the source
cluster tries to bring the Exchange virtual server on the source
online, the network name resource will fail and the group will
not come online. Allow the source cluster to finish trying to bring
the resources online before beginning failback.
2. In the Application Manager, make sure your source target pair is selected and then
on the Monitor tab, click Failback.
Note: The Failback button may not become active right away after completing a
failover. In this case, restart the Application Manager.
3. Specify the options for your failback and restoration.
