System panics to prevent potential data corruption

When a node experiences a split-brain condition and is ejected from the cluster, it panics and displays the following console message:

VXFEN:vxfen_plat_panic: Local cluster node ejected from cluster to 
prevent potential data corruption.

A node experiences the split-brain condition when it loses the heartbeat with its peer nodes due to failure of all private interconnects or node hang. Review the behavior of I/O fencing under different scenarios and the corrective measures to be taken.

See How I/O fencing works in different event scenarios.
