RAID - Forcing 'failed' to 'degraded'

One of the drives on my ICH10r 3x1TB RAID5 array went down a while ago. I just got the replacement and it seems to be fine, however I can't get the raid controller to do anything useful with it.

The volume is marked as 'failed' instead of 'degraded'. The manual for Intel Matrix Storage Manager says it should only be marked as 'failed' when more than one member drive has failed, however the software clearly indicates that there is only one missing drive and that the other two are 'normal'.

Does anybody know how to force a the ICH10r to make the array 'degraded' so it will attempt a rebuild? I've found some stuff about doing this with 'mkraid' but I have no idea how that applies to me.
 
So, when a disk failed, the Intel Matrix Storage Manger said the array was "failed", rather than "degraded"? The RAID array stopped working when the disk failed, rather than continuing to work in a "degraded" fashion with two working disks?

Does the Storage Manager show the remaining disks as Online or Offline?

You didn't update the motherboard BIOS, did you?

What version of the Intel Storage Matrix Manager are you using? Apparently versions 8.9 and 9.5 are known to incorrectly report disks as failed.

It became 'degraded' initially and continued to operate, then about a week later decided it was 'failed', with the 2 remaining drives continuing to show as 'normal'.
 
what probably happened is another drive threw an error so the controller marked the raid failed. can't you mark it back? or did you do something with the manager app or bios?

That's exactly what I'm trying to do, but I can't find any option to do that in the RAID BIOS or in Intel Matrix Storage Manager. Is there some other windows program I can access the array in and do that with?
 
I'm using ISM version 9.5.0.1037.

Can you open the Storage Manager, go to Manage > Advanced > and the hit the "Verify" tab?
 
if the system still believes there is a raid there - it will let you mark the raid from failed back to degraded. then you rebuild your raid with the new drive.

it's most certainly in the RAID bios on my ole dell inspiron 530. not the normal bios.

ISM should do it to but it has to believe there is a raid there. make sure you didn't do something dumb like set to AHCI mode and forget to set it back to RAID

It is not an option in the RAID BIOS, nor it is an option in IMSM. The controller is set to RAID in BIOS.
