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 (dimmed) if the virtual machine is powered off.


  1. In the vSphere Client, browse to the Primary VM for which you want to conduct the test.
  2. Right-click the virtual machine and select Fault Tolerance > Test Restart Secondary.
  3. View details about the test in the Task Console.


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 started, placing the Primary VM back in a Protected state.
