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).
