Group Failures

A group failure is when all the network interface cards appear to fail at the same time. in.mpathd does not do any failovers for a group failure. Also, no failover occurs when all the targets fail at the same time. In this instance, in.mpathd flushes all of its current targets and discovers new targets (see Detecting Physical Interface Failures).

Note –

Group failures were previously known as link failures.
