0029 units
0030 Summary of all units present in an IEEE 1394 node.
0031 Contains space-separated tuples of specifier_id and
0032 version of each unit present in the node. Specifier_id
0033 and version are hexadecimal string representations of
0034 u24 of the respective unit directory entries.
0035 Specifier_id and version within each tuple are separated
0036 by a colon.

0120 Description:
0121 SCSI target port identifier and logical unit identifier of a
0122 logical unit of an SBP-2 target. The identifiers are specified
0123 in SAM-2...SAM-4 annex A. They are persistent and world-wide
0124 unique properties the SBP-2 attached target.
0125
0126 Read-only attribute, immutable during the target's lifetime.
0127 Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
0128 Colon-separated hexadecimal string representations of
0129
0130 u64 EUI-64 : u24 directory_ID : u16 LUN
0131
0132 without 0x prefixes, without whitespace. The former sbp2 driver
0133 (removed in 2.6.37 after being superseded by firewire-sbp2) used
0134 a somewhat shorter format which was not as close to SAM.
