Fault Tolerance is turned o for the selected virtual machine. The history and the secondary virtual machine
for the selected virtual machine are deleted.
Suspend Fault Tolerance
Suspending vSphere Fault Tolerance for a virtual machine suspends its Fault Tolerance protection, but
preserves the Secondary VM, its conguration, and all history. Use this option to resume Fault Tolerance
protection in the future.
Procedure
1 In the vSphere Web Client, browse to the virtual machine for which you want to suspend Fault
Tolerance.
2 Right-click the virtual machine and select Fault Tolerance > Suspend Fault Tolerance.
3 Click Yes.
Fault Tolerance is suspended for the selected virtual machine. Any history and the Secondary VM for the
selected virtual machine are preserved and will be used if the feature is resumed.
What to do next
After you suspend Fault Tolerance, to resume the feature select Resume Fault Tolerance.
Migrate Secondary
After vSphere Fault Tolerance is turned on for a Primary VM, you can migrate its associated Secondary VM.
Procedure
1 In the vSphere Web Client, browse to the Primary VM for which you want to migrate its Secondary VM.
2 Right-click the virtual machine and select Fault Tolerance > Migrate Secondary.
3 Complete the options in the Migrate dialog box and conrm the changes that you made.
4 Click Finish to apply the changes.
The Secondary VM associated with the selected fault tolerant virtual machine is migrated to the specied
host.
Test Failover
You can induce a failover situation for a selected Primary VM to test your Fault Tolerance protection.
This option is unavailable (dimmed) if the virtual machine is powered o.
Procedure
1 In the vSphere Web Client, browse to the Primary VM for which you want to test failover.
2 Right-click the virtual machine and select Fault Tolerance > Test Failover.
3 View details about the failover in the Task Console.
This task induces failure of the Primary VM to ensure that the Secondary VM replaces it. A new Secondary
VM is also started placing the Primary VM back in a Protected state.
