| 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| (removed in 2.6.37 after being superseded by firewire-sbp2) used |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. |
