I assume you are using the ST25xx or ST6xxx storage with Lustre? Exactly which arrays? I've been happy with RDAC, but I don't think Oracle has released RHEL6 support yet (but Oracle also does not support Lustre servers on RHEL6 yet). If your multupath config is working (ie, you've tested it by unplugging/replugging cables under load and were happy with the behavior), I'm not going to tell you to change.
