Like James notes, LUNs should generally be treated as opaque values.
Maybe another issue to consider is how they are being displayed in userland.
A device with two luns using one of the alternative lun addressing methods is
going to get some pretty strange looking lun numbers showing up in userspace
if they aren't decoded properly.
One example of this is the ibmvscsi protocol. Since the ibmvscsi target
driver uses the LUN addressing method its LUNs show up with LUN numbers
256 512 768 ... at a Linux SCSI initiator.
