View Full Version : Raid 0+1 Won't Boot (with 1 drive failed)

08-14-05, 03:45 PM
Hello All:

I am running a Raid 0+1 (4 drives) and had a drive failure last night. The failure sounds like a problem with the drive arm solenoid, so it works on and off but it definitely needs to be replaced.

Here is the problem. With the drive unplugged, I get a red error message from the NV Raid Bios and the MOBO Bios no longer sees the Raid array. When I replug in the failing drive, the system will boot.

Shouldn't I be able to boot with one drive missing on a Raid 0+1 (or possibly even 2 drives if they are part of the same mirror)?

I don't have a replacement drive yet - it is still under warranty from Maxtor - but I would like to continue using my system until the new drive arrives.

Do I need to make any changes in the NV Raid Bios to allow me to reboot with a Degraded array? Any other suggestions?

My experience with RAID suggests that being able to boot a defective array is extra functionality that I havnt seen that much on IDE raid controllers, its likely you will need to replace the defective disk and rebuild the array before it will boot.

Is the drive that failed on port 1 or 2? Maybe you need to re-arrange the wiring so the mirrored drives are now considered the masters.
