PE 2450 with flashing health light and PERC Raid utility says Raid status is critical

PE 2450 with flashing health light and PERC Raid utility says Raid status is critical

[Dan Finn]

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
