Hi,
I'm trying to install Oracle 11gR2 RAC on AIX, do we need to turn on Multicasting, can we install without multicasting? Also can I have the ASM disk with external redundancy for OCR and Voting Disk?
Thanks.

Yes. As long as you are properly protected by "external means" (SAN mirror/raid for example).

Quote:

If you do not have a storage option that provides external file redundancy, then you must configure at least three voting disk areas to provide voting disk redundancy.
