Thanks for the reply.

I plan to use ASM over raw devices. (Again, this is purely for test/ learning, not a production application.)

Please correct me if I'm wrong, but I'm assuming that I'll need HBAs for both nodes to connect to the same LUNs on the SAN? (There's no way to do it without the HBA is there?)
