* It contains the target's EUI-64, a number given to the logical unit by

* the ieee1394 driver's nodemgr (starting at 0), and the LUN.
|

*
|

* The long format is: %016Lx:%06x:%04x
|

* It contains the target's EUI-64, the unit directory's directory_ID as per
|

* IEEE 1212 clause 7.7.19, and the LUN. This format comes closest to the
