OK, so what is the enclosure device at host 8? And what happens when
you use sg_ses to ask for page 7?

We run xfstests on the test machine. You can check the dmesg (kmsg.xz)
attached in the original reporting email for information about scsi host
8.

We run xfstests on the test machine. You can check the dmesg
(kmsg.xz)

host

It's not a test failure, it's a problem with your hardware, which looks
to be a Promise SAS expander with enclosure services.
can you run sg_ses <dev> on it followed by sg_ses --page=7 --hex <dev>?
To get the sg device run sg_map -i and it should tell you what the
mappings are.
Thanks,
James
