WWN and 73 GB Fujitsu Drives?

Folks,

We were installing some Fujitsu 73 GB drives in our V880 and noticed that
only the fujitsu 73's had a quirk for the last digit of the WWN. For the
same FC/AL disk, the last digit would change based on what path was used to
reach it. On a 280R (with no redundant internal pathing), the last digit
would be a zero, and the WWN on the drives label would match the output from
luxadm commands. The same drive in V880, with two paths (c1 and c2) would
result in the last number being 1 or 2 based on primary and secondary routes
(loopa or loopb) used to reach the disk.

Is this a bug or just a transparent nuisance? Seems its the only drive that
does this. Disks with the same part number (540-5408) have different
behaviours.

Sounds like its a nuisance at least.

Thanks!
