The Quantum GoVault SATAPI removable disk device returns ATA_ERR in

that is attached to a SAS controller (this is the case with sas_ata),
the device does not load because SCSI won't touch a "SCSI device"
that won't report its LUNs.  Since most ATAPI devices don't support
multiple LUNs anyway, we might as well fake a response like we do for
ATA devices.

I'm leaning towards applying this, perhaps with a module option that allows experimenters to revert back to the older behavior.

Any chance you could be talked into tackling some of the SAT translation-related items Doug G mentioned? I'm almost certain there are some info pages we should be returning, but are not, at the very least.

I thought we were closing in on agreeing that the SPC/MMC
inconsistencies made this the correct candidate fix.

that works for me...
