In my case, the nodes are connected to a hub, which is in turn connected to 
the brocade. Do I just use the brocade's port still?

I have not been able to find clear information on building a proper 
cluster.conf file either so have bits of this and that.

This is what I've got... you're sample and the bits and pieces I've been 

<?xml version="1.0"?>
<cluster config_version="40" name="vgcomp">
    <fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>
    <clusternode name="cweb92.xxx.com" nodeid="92" votes="1"/>
    <clusternode name="cweb93.xxx.com" nodeid="93" votes="1"/>
    <clusternode name="cweb94.xxx.com" nodeid="94" votes="1"/>
    <clusternode name="dev.xxx.com" nodeid="99" votes="1"/>
    <clusternode name="qm247.xxx.com" nodeid="247" votes="1"/>
    <clusternode name="qm248.xxx.com" nodeid="248" votes="1"/>
    <clusternode name="qm249.xxx.com" nodeid="249" votes="1"/>
    <clusternode name="qm250.xxx.com" nodeid="250" votes="1"/>
    <fencedevice agent="fence_brocade" ipaddr="x.x.x.x" login="user" 
name="brocade" passwd="xxx"/>
