Hi!
I can only recommend the system-config-cluster GUI, but if you feel
brave enough you can do it by hand
This example is for a sanbox2, but it should get you going:
...
<fence_daemon post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="clusty1" votes="1">
<fence>
<method name="1">
<device name="sanbox" port="0"/>
</method>
</fence>
</clusternode>
<clusternode name="clusty2" votes="1">
<fence>
<method name="1">
<device name="sanbox" port="1"/>
</method>
</fence>
</clusternode>
....
</clusternodes>
<fencedevices>
<fencedevice agent="fence_sanbox2"
ipaddr="xxx.xxx.xxx.xxx" login="username" name="sanbox" passwd="password"/>
</fencedevices>
...
And don't forget to check the fence_brocade manpage for your brocade
switch for further options...
Cheers,
Frank...
