● 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 data on the target at the time of
failover.
● Revert to specified snapshot—Select this option, and then select a
snapshot. The data on thetarget will be reverted to the selected snapshot.
This option will not be available if there are no snapshots on the target or if
the target does not support snapshots. To help you understand what
snapshots are available, use the Type and Status columns. The Status
indicates the state of the connection between the source and target at the
time the snapshot was taken. The Type information is displayed in the
following table.
Type Description
Scheduled● This snapshot was taken as part of a periodic snapshot.
Deferred
This snapshot was taken as part of a periodic snapshot, although it
did not occur at the specified interval because the connection
between the source and target was not in a good state.
User
Request
This snapshot was taken manually by a user.
3. 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.
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.
