Failover is automatically enabled for hosts using Network Attached Storage (NAS). This configuration enables operators to rescue virtual machines from a failed (and unreachable) host by moving the virtual machines to an operational host. In essence, an operational host may temporarily take over a failed host’s remote storage to retrieve the VMs, and those VMs can then be launched on the operational host.
