Oracle RAC on Linux...

I have been trying to get Oracle RAC running under linux (using Firewire) and have been having some problems with OCFS. At this point, it seems everything is working correctly on the firewire side (the sbp2 module loads and I can fdisk the firewire drive without any issues), but the loading of OCFS gets the following errors:

Oracle Cluster FileSystem 1.0.10-PROD2 Thu Oct 30 16:52:56 PST 2003 (build 58096323e868c6646e63f9c288d1e334)
(1132) ERROR: 'node_name' not set or too long, Linux/ocfsmain.c, 491
(1132) ERROR: 'ip_address' not set or too long, Linux/ocfsmain.c, 499
(1132) ERROR: 'guid' not set correctly, Linux/ocfsmain.c, 507

I am using the precompiled packages (RPMs) available at otn.oracle.com, but assume that I need to create some form of configuration file to satisfy the errors above. Is that correct, and if so, where and what does the configuration file contain?

Thanks

Environment:
