We have a brand new Compaq/HP ML 330 G3 server. What we would like to do is setup a RAID 5 array on the built-in CSB-6 RAID controller. Since the controller only supports 0, 1, and 0+1, we were planning on using Windows Server 20003's software RAID 5. We are not trying to software RAID the boot partition or system drive.
The problem we are having is that we are getting large spurts of random drive / controller failures in the event viewer and server monitors. On the Microsoft site, they say you can't use software RAIDs and hardware RAIDs on the same disks, but we trying to figure out if that is what's happening here. The controller BIOS calls the single non-RAIDed drives RAID 0, and doesn't give an option for anything else.
Do you think they are both doing some form of RAID and thus creating a conflict? Or could one bad disk in a Windows RAID 5 array cause random errors on all drives and the controller?
Any help would be much appreciated.
