Degraded RAID-1 will not rebuild

Last Modified: 2008-02-01
I have a major problem that I need someone's help on.  I have been in contact with Dell support who has been fantastic at trying to get this resolved...but I heard something I don't like and need other opinions.

I have a server running 2003, exchange, AD domain controller, DHCP, DNS, the whole ball of wax...

Here is the story:
Drive 0:1 degraded and the array won't rebuild.  So we determined that it had to be bad even though it wasn't saying so completely.  I installed the new drive and took out the old and the array won't rebuild.  So I put the old back in and still it won't rebuild (new and old are now installed).  The OS is booting fine and I am typing this from the machine in question.

Now, I have added the new drive as a hot-spare and the controller is still not picking it up to rebuild and it sat all night long.  Next step in the open manage server administrator was remove dead segments from the failed drive, I figured at this point why not.  Once completed it said drive ready, I made this a hotspare too and here I sit, array is still degraded and will not re-build.

I really need some advice as to what I need to be doing to fix this with out formatting and rebuilding the server (that is what I was told by dell - they think something is wrong with the raid-1 configuration).  We'd do a complete system and system state backup and start completly over with a new array etc...  I have the backup in progress now but do NOT want to do that.  There has to be another way.

I am seeing options like unmirror the array.  That would make drive 0:0 a standalone, after I do that can I re-create an array and have that remirror with out corruption?

Any guidance is much appriciated.
