OK, so this one is a RAID emulation device and likely won't work, but
the rest (apart from the ATA one) should.

Could you tell me what the enclosure page 0 (supported diagnostic pages)
and page 10 (additional information page that allows us to do the
matching) say? I suspect the enclosure either doesn't support the page
needed for the matching or there's some problem with the way the
information is encoded.

To get this information, you'll need to run sg_ses on the sg device for
the enclosure (the two promise ones).

Thanks,
