    Good day Team, I am struggling on VSphere with the following, we want to add a forth server to our current cluster, we want to enable EVC on the cluster, When we asks to select a processor we choose” Intel Sandy Bridge Family” as the other three Servers are all Sandy Bridge. We then get a compatibility error stating (The host cannot be admitted to the cluster’s current Enhanced vMotion Compatibility mode. Powered-on or suspended virtual machines on the host may be using CPU features hidden by that mode) Any Suggestions please.

    Thank you.
