Description nfxjfg 2021-12-12 16:06:19 UTC 
This would be a nice feature for using smartctl over iSCSI (where the target is a SATA disk). So far, this seems to be needed in the iSCSI target implementation or another part of the target's SCSI layer or SATA glue code. I can actually send ATA passthrough commands (0x85) from a Linux initiator, just the target rejects them as invalid or unknown.

Hints which subsystem or even source file would handle this would be nice too, maybe I could attempt a patch (though somewhat unlikely I would succeed).

Does iSCSI+SATA really work by translating SCSI commands to ATA commands? Crazy world if that's correct.
