When you enable this feature, a node automatically reboots, provided that the following conditions are met:
All monitored disk paths on the node fail.
At least one of the disks is accessible from a different node in the cluster.
Rebooting the node restarts all resource groups and device groups that are mastered on that node on another node.
If all monitored disk paths on a node remain inaccessible after the node automatically reboots, the node does not automatically reboot again. However, if any disk paths become available after the node reboots but then fail, the node automatically reboots again.
