| 30 | Summary of all units present in an IEEE 1394 node. |
| 31 | Contains space-separated tuples of specifier_id and |

| 109 | SCSI target port identifier and logical unit identifier of a |

| 114 | Read-only attribute, immutable during the target's lifetime. |
| 115 | Format, as exposed by firewire-sbp2 since 2.6.22, May 2007: |
| 116 | Colon-separated hexadecimal string representations of |
| 117 | u64 EUI-64 : u24 directory_ID : u16 LUN |
| 118 | without 0x prefixes, without whitespace. The former sbp2 driver |
| 119 | (removed in 2.6.37 after being superseded by firewire-sbp2) used |
| 120 | a somewhat shorter format which was not as close to SAM. |
