I'm somewhat used to modern SCSI HBAs export SCSI-2 disks= , but not supporting VPD pages at all is really a bit .. hmm .. SCSI-1-is= h. And it makes it really impossible to assign a persistent device ID to those drives. And it really made my eyes hurt. Now that I have the latest, top-of-the range SAS drives with a real HW RAID controller and the disks are exported as SCSI-2. Just as I thought we'd been finally past those days. Sigh. Anyway, I don't think that it should be too hard to add proper VPD page support (ie page 0x83), but for that one would have some documentation how to ask the controller for it. I'll leave that to you :-) You can use the page 0x80 support as a template.
