Can you try to turn off a single port of that hub via the brocade
switch? I doubt that there is any method in the brocade switch to do
that, but I could be wrong here.
Also if the hub is manageable there might be a way to disable certain
ports directly at the hub.
If neither works, you'll need to think of a different setup for SAN
fencing, like putting the nodes onto their own FC-switch, or consider
power fencing via a network manageable pdu or ups.
