In addition to Matthew's comments, I might add that all Veritas documentation is available at support.veritas.com.

RE: RAC - Configuring Disk Coordinator
Title: Message Whoops - I missed a question in there. Smallest lun possible? On the older HDS thunder systems, you can make teeny-tiny luns - I'm guessing the 9570V is the same way. Make a raid group and carve a few small luns out of it.
