Actually, I think what I want is: Fencing should always result in
poweroff, not reboot. I wonder if there is a clean way to do that?

Rationale: A node should never die. If it does, by definition, an
undefined state has occurred, and I would rather not have such a server
start without having a chance to look into log files, etc.

Hmm, good point. The ILO communication happens through cross-over cables
with endpoints in the ILO, and in a dedicated NIC. I guess that I may
ifdown the interface corresponding to the NIC on Node 1 (the one
performing the fencing).
