Possibly the drive does not support SMART queries ?
The illegal request is not due to a SMART query although it is due to
a query for drive status. This is the illegal request response that
scsi.d reports:
00011.633036046 ahci0:ILL 0x1a MODE_SENSE(6) address 01:00, lba
0x000300, len 0x000024, control 0x00 timeout 60 CDBP ffffff256b4f5c10
1 sched(0) cdb(6) 1a0003002400
The query seems to be made with each zfs transaction group.
The problem is occuring with two different vendors enterprise SATA
drives, but far more with a Western Digital drive. That one is now up
to an illegal request count of 26201.
