vSphere Fault Tolerance is used in the context of a vSphere HA cluster. After you have configured networking on each host, create the vSphere HA cluster and add the hosts to it. You can check to see if the cluster is configured correctly and complies with the requirements for the successful enablement of Fault Tolerance.


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


  1. In the vCenter Server inventory, select the cluster and click the Profile Compliance tab.
  2. Click Check Compliance Now to run the compliance tests.
    To view the tests that are run, click Description.


The results of the compliance test appear at the bottom of the screen. A host is labeled as either Compliant or Noncompliant.
