My customer has a VMware ESX 5.5 environment which consists of 5 hosts. One of the hosts lost network access to LAN and Management networks. None of the VMs failed over / migrated to the other hosts and became unavailable without network access until network access was restored. Checking the Cluster settings HA is enabled and Host Isolation is configured to Shut-Down. Now is this correct? How would I need to change the configuration so HA migrates VMs to another host in case this happens again?
