This will break existing IBM Power users who have more than 64 virtual disks assigned
to a single virtual scsi adapter. The IBM VSCSI target uses Logical Unit Addressing (10b)
and does bus/id/lun -> vscsi LUN mapping as defined in SAM. The 65'th virtual scsi
disk would show up on bus 1 as target 0.
