# Performing an Failover for Array Replication Failover Groups

You can perform an unplanned failover using an array replication failover group.

In an unplanned failover, the following events occur:

- The source VMs are powered off.

- The mirror relationship breaks.

- The volumes come online.

- The datastores are created.

- The VMs are registered, customization is performed, and the VMs are powered on.

## Before You Begin

If the same VM is included in both an array replication failover group and an array replication test failover group, and a test failover that includes the VM is either already mounted or in progress, then do not start a planned or unplanned failover. You must undo the test failover that includes the VM before you can perform a planned or unplanned failover that includes the same VM. For instructions, see Undoing a Test Failover

## Procedure

1. Log on to the Command Center.

2. From the Command Center navigation pane, go to Secure > Auto recovery > Failover groups.

3. In the Name column, right-click a failover group, and then select Unplanned failover.

   The Unplanned failover page appears.
