Problem with RAID1 Disk on Freebsd

[shakeb ainul]

Hi,

I am a developer with one of the top IT companies in Asia. I have the
following problem with my RAID 1 server.

Last week, the only disk of my server failed due to unknown reason and it
required a reboot of the server. Following error messages were logged in:

/var/log/messages

Nov 21 02:18:17 server1 kernel: ciss0: *** SCSI bus speed downshifted, SCSI
port 2
Nov 21 02:20:58 server1 kernel: ciss0: *** SCSI bus speed downshifted, SCSI
port 2
Nov 21 02:22:37 server1 kernel: ciss0: *** SCSI bus speed downshifted, SCSI
port 2
Nov 21 02:31:01 server1 kernel: ciss0: *** Physical drive failure: SCSI port
2 ID 1
Nov 21 02:31:01 server1 kernel: ciss0: *** State change, logical drive 0
Nov 21 02:31:01 server1 kernel: ciss0: logical drive 0 (da0) changed status
OK->interim recovery, spare status 0x0

Attached is the dmesg.boot file of my server.

Please advise on what could be the possible causes for this fault and what
can we do to ensure it does not happen again in future.

Thanks in anticipation.

Regards,
SHAKEB AINUL
