You mean you killed the switch for *both* nodes?

RHCS checks the signal on any interface bound to a virtual IP, so if that interface looses signal,
it'll try to relocate all services that include that ip resource. After all, if the virtual ip is on
an interface without signal, clients cannot reach the server and so it's as good as dead for any
practical purpose.

So if my assumption is correct your problem may is related to fence at all, but instead to the with
the way you tested failover. Try unpluging the cable on just one node at a time.
