John,
Two things.
1)You might want to post this on the RAC SIG. 2) You are better off sticking with raw devices with AIX . My experience with GPFS is that it is too new and buggy. If you have any specific questions hit me offline.

Subject: RAC Experiences

All,
Given some of the recent postings on RAC, we are probably crazy to continue looking at it. Still, we have an app that we can see scaling to 40+ CPUs in the next year and want some way to avoid buying ever bigger servers (with the attendant ever bigger $$) to handle it. Currently we are looking at IBM and are left with a few questions:

Is anyone running production RAC on AIX and what has the experience been from a reliability standpoint? Administrative difficulties? Etc?
Is anyone running production RAC on Linux on IBM hardware and what has the experience been from a reliability standpoint? Administrative difficulties? Etc?
IBM claims that their cluster software handles heterogeneous boxes quite well. We are considering the possibility of getting 3 4-way 530s to "prove out" and get RAC running. Later we would add in 650s for scaling up. Eventually the 530s go away and become something else, like a test RAC. Has anyone been running RAC in a heterogeneous environment and what have your experiences been?

Any practical experience feedback would be greatly appreciated.
