The enclosure:slots name comes from SCSI Enclosure Service (SES) definitions, and it is just enclosure-slot (no rank, row, column). Here, we use the SAS address of the SCSI Enclosure Processor (SEP) to identify the enclosure, while the slot is just numbers. For example: enclosure-0x570e2840203080ff-slot0 -> /dev/sdl enclosure-0x570e2840203080ff-slot1 -> /dev/sdj enclosure-0x570e2840203080ff-slot10 -> /dev/sdk At this time, this concept only applies to drives in SCSI enclosure. Other drives do not have this symlink.
