asked whether or not to delete the associated replica virtual machine, DO
NOT delete the replica, then confirm the selection.
Failing over a physical or virtual machine with Hyper-V to a
replica virtual machine
If you have not done so already, launch the Storage Mirroring Console, then click the
Monitor Connections button to manage failover.
Storage Mirroring Console provides the ability to failover to a replica virtual machine in
the event of a failure of the source machine. Source servers may be failed over in two
different ways:
● Automatic Failover—The application detects that a failover condition is met and
automatically initiates the failover process.
● Manual Failover—The user manually initiates the failover process by clicking the
Failover button in the user interface.
The type of failover for the job is selected during job creation. For more information, see
Setting protection options.
After the protection job completes the initial synchronization, failover will be enabled. To
initiate failover, select the connection and click the Failover button on toolbar at the
bottom of the Monitor Connections page.
During the failover process, the following steps are initiated:
1. The Storge Mirroring connection between the source machine and target Hyper-V
host is disconnected.
2. If you are performing manual failover and the source can be contacted, the source
machine is shut down.
3. The target virtual disk volumes are connected to the replica virtual machine.
4. The replica virtual machine is powered on.
Note:
During manual failover from a normally-functioning source machine, in some
cases the replica virtual machine may come online before the source has fully
shut down, resulting in an IP address conflict. In most cases, this situation will
be resolved once the source machine shutdown is complete.
Undoing failover
Once a test failover has been performed, it is possible to undo the failover by clicking on
the Undo Failover button. Undoing failover will do the following:
