    HA with Anti-Affinity Rules Scenario

    StephenMoll Hot Shot

      If I have 4 hosts in a cluster with HA protecting. For this scenario assume vSphere 6.5U2.

      I also have 4 VMs, which are all listed in an anti-affinity rule.

       

      So whilst all is running OK, each VM is running on a separate host.

       

      Now supposing one of the hosts goes bang!

      Does the VM that was running on that host get restarted on one of the three remaining hosts, contravening the anti-affinity rule, or is the VM left in a powered-off state?

      If HA does actually restart the lost VM, how is the host chosen?
