Sorry. perhaps I have failed to mention, the SCSI errors are only w/ the seagate drives. These are of the model ST4000NM0023. ________________________________ From: Shiva Bhanujan Sent: Tuesday, October 17, 2017 6:53 PM To: Kenneth D.

Merry Cc: freebsd-scsi@freebsd.org 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? ________________________________ From: Kenneth D.

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.

The HBA330 SAS-3 controller is in pcipassthrough mode to the FreeBSD VM. When I try to access the disks (/dev/da0...) using gpart, I get SCSI errors, like the following: > > > > > > > > (da0:mpr0:0:0:0): CAM status: SCSI Status Error > > > > (da0:mpr0:0:0:0): SCSI status: Check Condition > > > > (da0:mpr0:0:0:0): SCSI sense: ILLEGAL REQUEST asc:20,0 (Invalid command operation code) > > > > The error message above is missing the SCSI CDB.

I haven't checked the differences between the mpr driver in 10.2 vs 10.3 and 11.0. I do see that there are others who have experienced these issues.

Having said that, I still need to figure out what would happen, if the disks were written to using FreeBSD 10.2, which doesn't seem to have SCSI errors, and when I try to upgrade to 10.3.
