Hi!

We have a RAID5 over three discs on a PowerEdge 2550:

The afacli output hasn't changed since this array went into production.
But the kernel log now reports SCSI errors from time to time:

Jan  3 21:28:34 raman kernel: scsi1: ERROR on channel 0, id 0, lun 0, CDB: Read (10) 00 28 56 cd bb 00 00 08 00

This is /dev/sda12 which is a low priority swap partition and therefore
not used often. Linux kernel is 2.4.20.

Any hints are appreciated.
