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

119Description:
120 SCSI target port identifier and logical unit identifier of a
121 logical unit of an SBP-2 target. The identifiers are specified
122 in SAM-2...SAM-4 annex A. They are persistent and world-wide
123 unique properties the SBP-2 attached target.
124
125 Read-only attribute, immutable during the target's lifetime.
126 Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
127 Colon-separated hexadecimal string representations of
128 u64 EUI-64 : u24 directory_ID : u16 LUN
129 without 0x prefixes, without whitespace. The former sbp2 driver
130 (removed in 2.6.37 after being superseded by firewire-sbp2) used
131 a somewhat shorter format which was not as close to SAM.
