We are investigating a similar type of problem seen on several of our systems. Seemingly at random (though some systems seem more susceptible than others) we see the ata link reset and subsequently there is a FAILED TO IDENTIFY error logged. smartctl is unable to get information from the drive and a power cycle of the drive is required to bring it back on line. I would be interested to know if the ata level errors are similar to those we are seeing. -----Original Message----- From: linux-ide-owner@xxxxxxxxxxxxxxx [mailto:linux-ide-owner@xxxxxxxxxxxxxxx] On Behalf Of Caspar Smit Sent: 01 December 2009 12:16 To: linux-ide@xxxxxxxxxxxxxxx Subject: Random shutdown of disks using sata_mv Hi, I'm having a problem where in random one of my disks shuts down and is disconnected from the linux kernel. In other words I have to reboot the system or physically unplug/replug the disk to get it to work again. I will provide my configuration: SuperMicro SC-216 chassis (24 bay 2,5" disks) 24x Seagate ST9500420AS 500Gb 7200 RPM Hard Drives 3x SuperMicro AOC-SAT2-MV8 (SATA Controller using the sata_mv kernel driver) I use Debian Lenny 5.0 and kernel: linux-image-2.6.30-bpo.2-amd64 (2.6.30-8~bpo50+1) from the backports repository. The symptom is that after a while of operation a disk is shut down and kicked out of a RAID set. It doesn't matter if there is load or not on the system. The logging says: sd 11:0:0:0: [sdk] Unhandled error code sd 11:0:0:0: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK sd 11:0:0:0: end_request: I/O error, dev sdk, sector 0 In this case sdk, but it happens to all disks. Then the disk is not readable by the system anymore. When I check the disk for errors (badblocks/smart) in another system it doesn't give any errors. I only have this with 2,5" systems. Is this a sata_mv problem? A disk problem? or anything else? I can provide more info if needed.
