RDM compatibility modes

An RDM has 2 compatibility modes:

Virtual - Fully virtualized mapped device. Able to take advantage of VMFS benefits such as advanced file locking & use of snapshots. Looks like a standard virtual disk to the VM.

Physical - Minimal SCSI virtualization of the mapped device. VMkernel passes most SCSI commands to the device. Physical attributes of the underlying device hardware are exposed to the VM.

Both support vMotion.
