The AutoRestart attribute determines the VCS behavior in the following scenarios:
A service group cannot be automatically started because of a faulted persistent resource
A service group is unable to failover
Later, when a persistent resource transitions from FAULTED to ONLINE, the VCS engine attempts to bring the service group online if the AutoRestart attribute is set to 1 or 2.
If AutoRestart is set to 1, the VCS engine restarts the service group. If AutoRestart is set to 2, the VCS engine clears the faults on all faulted non-persistent resources in the service group before it restarts the service group on the same system.
