As I understand it, vSphere "Host Failure" happens when a host cannot communicate over management AND datastore networks, while "Host Isolation" occurs when either management heartbeat goes down or datastore heartbeat goes down for a host, but not both. Is this correct?
If host isolation is due to management network issues, I see no need to shutdown and restart VMs on a new host. However, in case of communication failure of a host to the datastore, restart of VMs is desirable. What HA response is recommended during Host Isolation? I seem to think Disabled is better if management troubles are more likely. Please advise. Thanks.
