PE 2450 with flashing health light and PERC Raid utility says Raid status is critical
I have a PE 2450 here that has had a flashing orange health light for a couple of months now. I scheduled some downtime for it last night to investigate. The raid utility says that RAID0 (a raid 5 array with 3 18G drives, the only raid array on the system and the only drives in the system) is critical, but it does not tell me why or what is wrong. It lists all 3 disks and it doesn't show any errors for them at all.
This server is running redhat 6.2 and kernel 2.2.14-6.1.1smp, loading the percraid kernel module. It has been running fine now for quite some time but I would like to figure out if there is really a problem or not.
After rebooting it the health light on the front of the server is now solid green, which I think is how it should be if there are no problems. But, during bootup I still see the error from the scsi card saying that the raid is critical.
I came accross this site:
http://www.redflag-linux.com/ppd/product_files/2003-AP001-01-01/base_doc/Dell_AACRAID.htm
And installed the Dell command line interface software from:
http://www.domsch.com/linux/aacraid/afaapps-2.6-0.tar.gz
I then can use the software and get the following for output:

Pretty cool software but it's still not telling where the problem is. Could it be flaky software on the PERC controller, and there really isn't a problem?
Any help would be really appreciated.
Thanks
