I see K Gopalakrishnan has already responded and added a version warning. He even spelled his own name correctly. Sorry about the extra "la" in my earlier post.

I believe the commands you want are ocrconfig and crsctl.
I think I've seen the details in K Gopalalakrishnan's book on RAC, and in the Julian Dyke/Steve Shaw book as well if you need something more succinct and clear than the manuals.
