SCSI-2 defines only up to 256 LUNs with a flat namespace.

My SCSI-2 draft (revision 10b from August 1989) only has
3 bit LUNs placed in byte 1 of the command block, in the top
3 bits. There are also things called LUNTARs and LUNTRNs
at the message level.

8 bit LUNs do ring a distant bell, perhaps after SCSI-2?

Yeah, you're right. SCSI-2 defines a 3-byte LUN; starting with SCSI-3 it went to 64bit.

I'll be renaming them to 'sdev_lun8'.

Cheers,

Hannes
