3. Select the target machine that is currently standing in for the failed source.
4. Highlight the failed source and click Failback. The failback script created earlier will automatically run.
During failback, Windows Event Viewer and the Storage Mirroring log record the failback events.
When failback is complete, the Exchange services will be stopped on the target and the Failback
Complete dialog box will appear.
5. Do not select Continue or Stop at this time. First, reconnect the source to the network.
6. After the source is available on the network, select Continue (to restart monitoring) or Stop.
7. To begin the restoration process, open the Storage Mirroring Management Console on the target
(Start, Programs, Storage Mirroring, Management Console).
8. Login to the source machine by double-clicking on it.
9. Right-click on the original connection and select Disconnect.
10.Select Tools, Restoration Manager.
11.Complete the appropriate fields on the Restoration Manager.
• Original Source—The source where the data originally resided.
• Restore From—The target that contains the replicated data that users have been updating.
• Replication Set—The name of the replication set
• Restore To—The source where the data will be restored to.
12.Disable Only if backup copy is more recent. This option must be disabled because if the Exchange
services were stopped on the source after the time they were stopped on the target, the source files will
have a more recent date and time and the target files will not be restored.
13.Identify the correct drive mappings for the data and any other restoration options necessary. For
detailed information on the restoration options, see the HP OpenView Storage Mirroring user's guide.
14.On the Orphans tab, select to move or delete orphan files on the source. Orphan files, such as
out-dated transaction logs, may keep the database from starting on the source. For more information
about orphan files, see the HP OpenView Storage Mirroring user's guide.
15.Verify that the selections you have made are correct and click Restore. The restoration procedure time
will vary depending on the amount of data that you have to restore.
NOTE: When the restoration process is complete, the restoration status information will no longer appear
in the right pane.
16.Continue to the next section, ”Running the Exchange Failover utility”, to complete the restoration
process.
