Ah, I'm at the command line :). 

So, there is nothing I need to do on the brocade itself then? The cluster 
ports aren't connected directly, they are connected into a compaq hub, then 
the hub is connected into the brocade. The brocade seems to know about the 
external ports however since they are listed when I look on the switch.

As for the conf file, I've not found enough information on how to build a good 
conf file so know this one is probably not even complete. Been working on 
other parts of the problems then wanting to get to this.
