Hello SCSI people, I'm seeing an issue with SMART queries on SATA devices connected to MegaRAID SAS9261-8i controllers. OS: FreeBSD 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #12: Wed Dec 15 01:16:54 EST 2010 amd64 Driver: dev.mfi.0.%pnpinfo: vendor=0x1000 device=0x0079 subvendor=0x15d9 subdevice=0x0700 class=0x010400 dev.mfi.0.firmware: 12.11.0-0016 Disks: Intel X25-E, ATA SSDSA2SH064G1GC 8860 Seagate Barracuda.2 ES, ATA ST3250310NS SN06 Smartctl is correctly detecting that the device is a SAT-connected ATA device, and can complete all of the other commands it tries (IDENTIFY DEVICE, SMART READ ATTRIBUTE VALUES, etc). The SMART STATUS CHECK fails every time, though, in exactly the same way. I've reproduced it on multiple disks connected to multiple controllers. It happens with smartctl 5.39.1 and 5.40. This is the command that fails: > REPORT-IOCTL: Device=/dev/pass14 Command=SMART STATUS CHECK > Input: FR=0xda, SC=...., LL=...., LM=0x4f, LH=0xc2, DEV=...., CMD=0xb0 > [ata pass-through(16): 85 06 2c 00 da 00 00 00 00 00 4f 00 c2 00 b0 00 ] status=0 > Incoming data, len=0: > Error SMART Status command failed > Please get assistance from http://smartmontools.sourceforge.net/ > REPORT-IOCTL: Device=/dev/pass14 Command=SMART STATUS CHECK returned -1 This appears in the log: > Dec 15 17:55:11 system13 kernel: mfi0: 3255 (345750911s/0x0002/info) - > Unexpected sense: PD 07(e0xfc/s2) Path 4433221102000000, > CDB: 00 00 00 00 00 00, Sense: 0/00/00 The CDB is empty - very odd. Any pointers on how I can begin to debug this? Is it a driver or firmware issue? I don't think it's a smartctl issue because the same command works fine on mpt-connected SATA devices. Thanks, Andrew P.S. Pulling in SVN 216235 didn't seem to make a difference. -------------------------------------------------- Andrew Boyer aboyer@averesystems.com
