The controller is aic7880U on-board on a dual p2 266 system . Today I found the system unable to access data on the raid array and the following in the logs : Jun 24 15:23:23 foo kernel: (scsi0:A:2:0): Unexpected busfree in Data-in phase Jun 24 15:23:23 foo kernel: SEQADDR == 0x7d Jun 24 15:23:23 foo kernel: SCSI disk error : host 0 channel 0 id 2 lun 0 return code = 10000 Jun 24 15:23:23 foo kernel: I/O error: dev 08:11, sector 1269344 Jun 24 15:23:23 foo kernel: Device 08:11 not ready.

Jun 24 15:23:27 foo kernel: I/O error: dev 08:11, sector 1292416 and those messages go on for hours . Apart from that , the system works ok . A reboot followed by an fsck results in a system working ok , with no data loss . Extensive read/write operations ( copying of big files /many small ones ) seem to work ok . The message has not reappeared as yet . The errors occured after roughly 7 days of uptime , during which there has been continuous read operation from the array , from 200 kbytes/sec to 1 Mbyte/sec ( the system is a busy ftp server ) this the output of /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: QUANTUM Model: VIKING II 9.1WLS Rev: 5520 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: IBM Model: DNES-309170W Rev: SA30 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 04 Lun: 00 Vendor: QUANTUM Model: VIKING II 9.1WLS Rev: 5520 Type: Direct-Access ANSI SCSI revision: 02 Any advice is welcomed .
