Please note, that this isn't an issue w/ Toshiba drives. is this a = firmware issue by any chance? ________________________________ From: owner-freebsd-scsi=40freebsd.org = =5Bowner-freebsd-scsi=40freebsd.org=5D on behalf of Shiva Bhanujan = =5Bshiva.bhanujan=40quorum.net=5D Sent: Tuesday, October 17, 2017 6:08 AM To: Kenneth D. Merry Cc: freebsd-scsi=40freebsd.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.

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.
