Please note, that this isn't an issue w/ Toshiba drives.  is this a =
firmware issue by any chance?

Subject: RE: FreeBSD 10.3/11.0 SCSI errors with Symbios Logic SAS3008 =
PCI-Express Fusion-MPT SAS-3

Since I started having the SCSI errors, I ended up running sg_format to =
format the disks. I've found that once the disks are formatted using =
sg_format, there are no SCSI errors. The errors that show up during the =
format are towards the end of the dmesg output.

(da0:mpr0:0:8:0): SCSI sense: NOT READY asc:4,4 (Logical unit not ready, =
format in progress)
(da0:mpr0:0:8:0): Progress: 9% (6256/65536) complete

once the format is done, I can successfully format and partition using =
gpart.


The errors that show up when I try to run gpart for the first time are as =
follows:

(da9:mpr0:0:17:0): READ(10). CDB: 28 00 00 00 00 00 00 01 00 00
(da9:mpr0:0:17:0): CAM status: SCSI Status Error
(da9:mpr0:0:17:0): SCSI status: Check Condition
(da9:mpr0:0:17:0): SCSI sense: ILLEGAL REQUEST asc:20,0 (Invalid command =
operation code)
(da9:mpr0:0:17:0): Error 22, Unretryable error


It seems that it's the read that is failing, and is being tagged as an =
illegal request. While sg_format will address the issue at hand, this =
isn't an option for us, because there are appliances that were formatted =
using FreeBSD 10.2, and an upgrade to 10.3 or 11.x might be an issue?

Yes, the mpr(4) driver is in all recent FreeBSD releases.

In looking at the dmesg, this is telling:

(da0:mpr0:0:8:0): WRITE(6). CDB: 0a 00 00 00 01 00
(da0:mpr0:0:8:0): CAM status: SCSI Status Error
(da0:mpr0:0:8:0): SCSI status: Check Condition
(da0:mpr0:0:8:0): SCSI sense: NOT READY asc:4,4 (Logical unit not ready, =
format in progress)
(da0:mpr0:0:8:0): Progress: 9% (6256/65536) complete
(da0:mpr0:0:8:0): Error 16, Unretryable error

If the drives are in the process of formatting, I guess it may make sense
for them to reject read commands. Otherwise, it makes no sense for a hard
drive to reject reads.

Are you able to check the status of the format? You should be able to send
a test unit ready and figure out how far along the format is:

camcontrol tur da0 -v

And so on for each of the drives.
