Albert, thanks a lot for your answer. The only log i can trace back now is Device: /dev/sda, ATA error count increased from 11605 to 11610 because it's stored on our RequesTracker I have also some notes about ATA: abnormal status 0xD0 on port 0xE407 Jan 26 06:12:29 ns kernel: ata2: command 0x25 timeout, stat 0xd0 host_stat 0x21 Jan 26 06:12:29 ns kernel: ata2: translated ATA stat/err 0xd0/00 to SCSI SK/ASC/ASCQ 0xb/47/00 Jan 26 06:12:29 ns kernel: ata2: status=0xd0 { Busy } Jan 26 06:12:29 ns kernel: SCSI disk error : host 3 channel 0 id 0 lun 0 return code = 8000002 Jan 26 06:12:29 ns kernel: Current sd08:10: sns = 70 b Jan 26 06:12:29 ns kernel: ASC=47 ASCQ= 0 Jan 26 06:12:29 ns kernel: Raw sense data:0x70 0x00 0x0b 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x47 0x00 0x00 0x00 0x00 0x00 Jan 26 06:12:29 ns kernel: I/O error: dev 08:10, sector 0 Jan 26 06:12:29 ns kernel: ATA: abnormal status 0xD0 on port 0xE407 This is taken from of those broken disks that's still attached on the second port of one of the servers, i left it only to try figuring this out. I tried replacing the cables, etc. But the disks are really broken. replacing them it works, maybe with no further errors. Yes, i can remember about different error messages. And i can only wait for it to happen again, if you need more logs How did you work the 3Ware firmware thing?
