Many thanks for your help Sunil. One more question my final intention is to do it in a silent mode. Can the ocfs2console step be replaced with a sequence of commands?
I mean, my final goal is add a node to an existing Oracle RAC automatically. Do you think that it is possible from the ocfs perspective?

Run ocfs2console on all existing nodes to add the new node. Note adding on one and propagating to others will not work. One needs to add on each active node via ocfs2console. Once added, the new node should show up in /config/cluster/<clustername>/nodes. Ensure you see the new node on all active nodes. Then copy the updated cluster.conf to the new node and start the cluster and mount.
