Clear! In order to do fence and crash a node, is there a specific HW 
requirement to do this?

No, just the pacemaker instance on the machine that lost corosync.

Whichever node that lost it's corosync version. If corosync dies,
pacemaker can't and won't do anything. It's dead. It will not restart.
The other node(s) in the cluster will declare that node lost and will
fence it.
