HP StorageWorks Storage Mirroring Full-Server Failover Evaluation Guide (T2558-96331, April 2009)

4 - 8
Click OK to initiate failover. Monitor the failover percentage as shown in the Protection Status. At
the end of failover, the target will be rebooted automatically. After the reboot, the target will no
longer exist, since it will become the source.
After your target has failed over and becomes your source, you can stay with that configuration long
term. However, in some instances, it may be necessary or desired to go back to using the original
hardware after you have failed over. See the Full-Server Failover Guide for details on the process to
failback to your original (or other) hardware.
NOTE: Because the Windows product activation is dependent on hardware, you may need to
reactivate your Windows registration after failover. Follow the on-screen prompts to
complete the reactivation.
If you are failing over a cluster node, it is possible that volumes may lose their drive letter
assignments. If a clustered application fails to start after failover and the disk signature
has changed, check the drive letter assignments under the Disk Management utility and
re-create drive letter assignments as needed.
