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

Description: |
|
Attributes common to IEEE 1394 node devices and unit devices. |
|
Read-only. Mutable during the node device's lifetime. |

These attributes are only created if the root directory of an |
|
IEEE 1394 node or the unit directory of an IEEE 1394 unit |
|
actually contains according entries. |

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(removed in 2.6.37 after being superseded by firewire-sbp2) used |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