The problem is:

no power = no ping + no DRAC access
no network = no ping, no DRAC access

If there's no power, then it is safe to fail over.

If there is no network (and power is OK), then it is not safe to fail
over.  Failover in this case is very likely to produce data corruption!

Because we can not tell which case happened, we do not fail over.
