Mark is right.

ASM is not your only choice. You could use raw devices (I would prefer ASM in that case, but that's just me) or you could use a Clustered filesystem, which in your case would be Veritas clustered filesystems. I doubt that's certified with 11g yet, so if it has to be 11g you probably have to use ASM or raw.

To answer your other question, the devices has to have the same name on all nodes in the cluster. This is because you really only create the diskgroup on one node and the disks then has to have the same name for the other ASM instances to recognize it.
