Simulating a failure
To fully evaluate the process, you need to simulate a failure. To do this, power off the source server.
Starting failover
When a failover condition is met, you will want to start failover. Additionally, you can start it without a failover condition, as
long as protection is enabled. For example, you may want to force failover when upgrading to a better source server.
To start failover, click
Failover. You can also select Actions, Failover.
If Full-Server Failover determines there is a possibility that the data on the target is incomplete, you will be warned before
failover begins. If you proceed with failover, the state of the source will be unknown until failover is complete. The best case
scenario would be a missing data file, while the worst case scenario would be missing system state data that causes the server
to be unusable or unbootable.
 Shutdown source server if running—If the source is still running, Full-Server Failover Manager can stop it. Although, if
Full-Server Failover Manager cannot communicate with the source, the shutdown command will fail. This option prevents
network conflicts in those cases where the source and target are still both running and communicating, such as a forced
failover.
 Use live data—Select this option to use the current data on the target.
 Revert to specified snapshot—This option is not necessary for this evaluation.
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.

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.
