vSphere Fault Tolerance is used in the context of a vSphere HA cluster. After you configure networking on each host, create the vSphere HA cluster and add the hosts to it. You can check to see whether the cluster is configured correctly and complies with the requirements for the enablement of Fault Tolerance.
- In the vSphere Client, browse to the cluster.
- Click the Monitor tab and click Profile Compliance.
- Click Check Compliance Now to run the compliance tests.
The results of the compliance test appear, and the compliance or noncompliance of each host is shown.
