  94. Description:
  95. SCSI target port identifier and logical unit identifier of a
  96. logical unit of an SBP-2 target. The identifiers are specified
  97. in SAM-2...SAM-4 annex A. They are persistent and world-wide

  99. Read-only attribute, immutable during the target's lifetime.
  100. Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
  101. Colon-separated hexadecimal string representations of
  102. u64 EUI-64 : u24 directory_ID : u16 LUN
  103. without 0x prefixes, without whitespace. The former sbp2 driver
  104. (removed in 2.6.37 after being superseded by firewire-sbp2) used
  105. a somewhat shorter format which was not as close to SAM.
  106. Users: udev rules to create /dev/disk/by-id/ symlinks
