Failback and restore Page 504 of 677
11. After the Mirror Status is Idle, schedule a time for failback. User downtime will
begin once failback is started, so select a time that will have minimal disruption on
your users.
12. When you are ready, begin the failback process. User downtime starts now.
a. Deny user access to the target, so that no additional updates can be made to
the data on the target.
b. Stop all applications on the target, allowing the data to become quiescent.
c. In the Replication Console, watch the restoration connection until activity has
ended and replication is in a Ready state. This will happen as the final data
in queue, if any, is applied on the source. The replication Ready state
indicates replication is waiting for new incoming data changes.
d. Open the Failover Control Center.
e. Select the target that is currently standing in for the failed source.
f. Select the failed source and click Failback.
Note: If the target is a cluster, you will need to determine the active node and
failback from that node. Then you will need to failback from each of
the other nodes to synchronize all of the nodes of the cluster.
g. You will be prompted that the restoration connection is still in place. Continue
with the failback. If you have a pre-failback script configured, it will be started.
h. When failback is complete, the post-failback script, if configured, will be
started. When the script is complete, you will be prompted to determine if you
want to continue monitoring the source, do not select either option. Leave the
prompt dialog box open as is.
i. Since failback has occurred, your restoration connection is no longer valid
and will be marked with a red X. Disconnect the restoration connection.
Note: If your target is a cluster, take the Double-Take Source Connection
resource offline to disconnect the connection.
j. On the source, change the IP address that you modified earlier to the unique
address back to its original address. You can also enable any other NICs on
the source.
