I had similar messages in the logs of a PE2650
 with Perc3/DC 7 Disk Raid 5 array running Suse Pro 8.1.
Luckily the hardware was due for upgrading anyway
 so I immediately copied everything across and put
 the replacement machine and array into production.
I was glad I did because in the course of debugging it
 under instruction from the Dell tech we lost the lot.
By way on an appology, Dell replaced the card, SCSI cable
 and 2 disks, so I don't know just where the problem was.

That machine is back in production as spinning backup
 and all arrays now have hot spares in them,
 but I would love to know how to monitor
 both the logical volume (degraded, disk swapped out, etc)
 and the individual disk SMART info
 without dropping down to BIOS.
