To recap:
I am attempting to setup a 2 node cluster where each will run a DB and
an apache service to be failed over between them. Both are fenced via
Dell DRAC connected via the system NICs (this adds to the issue, but
manual fencing is broken).
My test case so far is to unplug the network cables from one node and
then reconnect them. For some reason, both machines get halted instead
of one machine being fenced. Having only one node fenced in this
scenario has only occurred successfully one time.
I previously suspected DRBD as being the culprit, but I can now rule
this out after performing the cable pull test without RHCS running, and
having DRBD in every possible configuration the cluster could put it in,
including a split brain (which is impossible for me due to services not
failing over until fencing occurs).
Is there any component of the cluster system that would issue the
shutdown command shown in the log entry below?

Thanks to a hardware issue on NodeB, I am unable to get to the logs off
of it presently.
