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.
