ok, a clean start this morning, and I found the fence configuration 
under each cluster node.     for the qlogic sanbox2 fencing driver, I'm 
not sure if I'm suppose to put in the integer port number ('13'), the 
port name ('port13'), or the porrt address ('010d00') or what?   Tried 
the first and last of those, and it still doesn't seem to be fencing :-/q

ok, fence_sanbox2 -a svfis-sanbox -l XXXXX -p XXXXX -n 14 -o disable
seems to work.   so I guess its the port number, like 13 or 14....   
maybe I just need to reboot everything to get the fencing settings 
working, hmmm.
