How to replace one disk on HP Microserver G7 RAID 1

Hi

The HP Microserver G7, P/N: 658552-421
2 pcs 500 GB Disks, System, RAID1
2 pcs 3TB GB Disks, hided Win BU disks, RAID 1 (these can actually be 3TB disks)
The server beeps time to times (haven't been at site for awile). Will be there tomorrow.
At Win Disk Manger I can see both 500GB disks (SYSTEM) and the Disk 0 is Online but Disk 1 is Offline. The Disk 1 states:

" Offline (The disk is offlinen because it has a signature collision with another disk that is online)

I tought that WIndows will se only one disk since there is a HW Raid involved. At least WIndows can't see both hided BU disks.

At event viewer I can see this:

It's always a good idea to back up your system before mucking with the disks.  Take a the necessary time to do that before proceeding.

The MicroServer doesn't have hot-pluggable disks so you'll have to power the system off.    See the product manual at http://images10.newegg.com/User-Manual/User_Manual_59-108-164.pdf

Power the server back up, and hit F10 at POST to go into the RAID configuration.  You may need to tell the system to bring the new drive into the RAID set -- maybe not if you're lucky, but it's a possibility.    If there are any warnings, heed them, and make sure you have a current backup before making potentially data-destructive changes.

My MicroServer has been running without fault for several years -- I really like the system.

Thanks SelfGovern

Do you have any idea why I can see both RAID 1 disks from Windows? The HW RAID went broken for some reason and now I can see bothj disks from Windows?

Are you sure it was hardware RAID and not RAID built with Windows?

What happens if you use F10 at boot (before changing anything) and go into the AMD RAID utility?  What does it say you have?

Hi

By installing AMD Raidxpert i was able to investigate which disk were broken. Then after replacing the fault one I was able to add the new diks as spare drive. Once Raidxpert  noticed there is a spare drive it started automaticly recover the RAID.
