[Linux-cluster] Fencing using brocade

[isplist at logicore.net]

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 
using.

<?xml version="1.0"?>
<cluster config_version="40" name="vgcomp">
    <fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>

    <clusternode name="cweb93.xxx.com" nodeid="93" votes="1"/>

</clusternodes>
        <cman/>
<fencedevices>
    <fencedevice agent="fence_brocade" ipaddr="x.x.x.x" login="user" 
name="brocade" passwd="xxx"/>
</fencedevices>
        <rm>
                <failoverdomains/>
                <resources/>
        </rm>
</cluster>
