Recently, in draft spc5r08, T10 added a locally assigned RFC 4122 UUID *** designation descriptor. That descriptor can now be returned for VPD page 0x83 (device identification) amongst others. It can be used anywhere SCSI needs a unique identifier expanding the previous set of preferred identifiers: EUI, NAA and SCSI_name (iSCSI). In the soon to be released sg3_utils version 1.42 the new UUID designation descriptor is decoded including Hannes' --export option found in sg_inq, for example: # sg_inq --export /dev/sg0 ... SCSI_IDENT_LUN_UUID=11223344-5566-7788-aabb-ccddeeffffee Perhaps some udev work is needed to incorporate this new identifier.
