Hello Martin,

Sorry for the late reply but it's only now that I noticed this patch.
Are you sure that presence of a NAA descriptor is mandatory ? This is
what I found in SPC-4 r37 paragraph 7.8.6.2.1:

<quote>
At least one designation descriptor should have the DESIGNATOR TYPE
field set to:
a) 2h (i.e., EUI-64-based);
b) 3h (i.e., NAA); or
c) 8h (i.e., SCSI name string).
</quote>

I think this means that presence of one of these three types of
descriptors is sufficient in order to be compliant with SPC-4.

Thanks,

Bart.
