Hi there.
I've seen a lot talking about VMDKs and Virtual RDMs being shared between RAC nodes with "multi-writer" flag.
I also found out that this is working out with Physical RDMs, but i didn't see any statements on that. Only, as by best practices using Physical RDMs with the "Shared" option on the SCSI Controller.
Can anybody say if it's also supported to use "multi-writer" on Physical RDMs?
