Re: [Linux-cluster] Fencing using brocade

The system-config-cluster application supports brocade fencing. It is a
two part process - first you define the switch as a fence device; type
brocade, then you select a node an click "Manage fencing for this node"
and declare a fence instance.

For what ever reason, I cannot run system-config-cluster on any of my machines. Could you look at this and let me know if it looks right? Seems to be working.

<?xml version="1.0"?>
<cluster config_version="57" name="vgcomp">
<fence_daemon clean_start="1" post_fail_delay="0" post_join_delay="3"/>
   <clusternodes>
       <clusternode name="compdev" votes="1">
               <fence>
                   <method name="1">
                       <device name="fence_brocade" port="0"/>

Here you are not referring to the name of the fence device, but the agent name. you need to refer to the name you gave the fence device - in this case, "brocade". Same for all nodes.
