You can induce the failure of a Secondary VM to test the Fault Tolerance protection provided for a selected Primary VM.

This option is unavailable (grayed out) if the virtual machine is powered off.

Launch the vSphere Client and log in to a vCenter Server system.


In the vSphere Client, select the Hosts & Clusters view.


Right-click the fault tolerant virtual machine and select Fault Tolerance > Test Restart Secondary.

This task results in the termination of the Secondary VM that provided Fault Tolerance protection for the selected Primary VM. A new Secondary VM is then started, placing the Primary VM back in a Protected state.
