Re: [Linux-cluster] Fencing using brocade

I want to use my brocade switch as the fencing device for my cluster. I

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.

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.

Why build it yourself? The app will do it for you, and not make a typo that could cost you valuable time. If you don't have X running on your nodes, no problem - just install the s-c-cluster app anywhere...it will let you configure a cluster and then save out the conf file which you can propogate to the cluster yourself, if you want.
