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130		(removed in 2.6.37 after being superseded by firewire-sbp2) used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