| units | |
| Summary of all units present in an IEEE 1394 node. | |
| Contains space-separated tuples of specifier_id and | |
| version of each unit present in the node. Specifier_id | |
| and version are hexadecimal string representations of | |
| u24 of the respective unit directory entries. | |
| Specifier_id and version within each tuple are separated | |
| by a colon. | |

| Description: | |
| SCSI target port identifier and logical unit identifier of a | |
| logical unit of an SBP-2 target. The identifiers are specified | |
| in SAM-2...SAM-4 annex A. They are persistent and world-wide | |
| unique properties the SBP-2 attached target. | |
| Read-only attribute, immutable during the target's lifetime. | |
| Format, as exposed by firewire-sbp2 since 2.6.22, May 2007: | |
| Colon-separated hexadecimal string representations of | |
| u64 EUI-64 : u24 directory_ID : u16 LUN | |
| without 0x prefixes, without whitespace. The former sbp2 driver | |
| (removed in 2.6.37 after being superseded by firewire-sbp2) used | |
| a somewhat shorter format which was not as close to SAM. | |
