Sadly, that won't work.  The fence script for brocade instructs it to
turn off a specified port.  All your machines hook up to the switch
through a single port.  So when a node acts up, you disconnect ALL of
your nodes nodes from the storage at the same time, since they all are
connected to port 0 (through the hub).

For SAN fabric fencing to work, each server needs to be connected to the
brocade switch on it's own switch port.

Thanks,
