Closing due to lack of feedback. The issue may be specific to the disk model or firmware.

@Alex Diamantopulo, guessing the problem is in requesting list of log pages, could you run `sg_logs /dev/da6`? It should be the same SCSI command just run with different tool. Will it also fail and increment error counter? If so, than this drive is just insane, since while it is OK to not support log pages, it is definitely not an error for the host to try request it.

@Alex Diamantopulo, apologies... No wish/intention to muddy up the original issue. My problem too began with the 11.3 upgrade and I now see/notice numerous recorded "Non-medium error count" across the affected drives (not exactly sure when they were recorded). My errors are definitely not constant with time and are not caused by smartctrl. My issue appears repeatably with each attempted pool scrub. Pool operates otherwise normally but fails with R/W CAM errors during scrub. I will look elsewhere.

@Roy A Sutton, You're having a completely different problem.
My problem is triggered by checking the SMART status of the disks by running:
**
smartctl -a /dev/da6Every time after executing smartctl my disks getting registered one more "non-media errors" error.

After a recent upgrade from 11.2-U8 to 11.3-U2 we have noticed a rapid and constant growth of "non-media errors" in all 12 connected disks simultaneously. I tried to replicate the issue on the test server and with the same hardware but fresh installation (no pools) new disks showed the same behavior.
UPDATE: This happens every time I run smartctl, like: smartctl -a /dev/da6
It affects 11.3 only, no issues on 11.2 or older.
No such problems with 11.2-U8.
After rolling back from 11.3-U2 to 11.2-U8 errors stopped growing.
Of course, now we can't change the counter on our new disks back to normal values...

Please check the attached screenshots for non-media disk errors and other details.
Before the upgrade, all disks had <500 errors.
