Windows server 03 does not recognize array after drive replacement

I have a Dell 2800 server, Windows 03 Server. I had one drive in a 4 disk raid 5 array showing a "predictive failure", so I swapped out the drive. Initially, there was an error message at startup of the raid controller, so Dell had me stop the server, un-seat the driver, start it up, clear the array configuration, then stop it, re-set them, and start it again. This reset the array configuration from the disk information, successfully corecting the error problem.

However, Once I loged into Windows, the system cannot see the array drive.

It shows the OS mirror, another mirror I setup for other data, but the array that had the replaced drive shows up as both a new un-allocated drive, and a missing drive.

I have done everything short of formatting the unallocated space and I am now at a loss of what to do to save this. I keep thinking that there has to be something in the registry to adjust to fix this, but don't have any more ideas

Thanks in advance for your assistance.

Clearing the array configuration is data destructive process? I think that Dell tech says that delete the array and recreate them, deleting all data. Can verify this point contacting with Dell again? Have you got any backup?

Good luck.

You swapped the drive cold by the sound of it. Was it a new clean drive or a second hand one with metadata on it? If the latter then taking the configurations from the disk may have taken old stale info from that one.

Deleting the config from the controller and then picking it up from the disk shouldn't lose data if the disk config is correct, but you may need RAID Reconstructor from runtime.org and a Non-RAID controller to de-stripe the data if you can't set the config back correctly and don't have a backup.

It really sound like the tech had you pull all the drives, clear the configuration of the array's from the controller, the put the drives back in and let the controller re-read the configuration from the drives.

However it sounds like only the OS array is online. There is not enough information to tell what the status of the second array may be.

Get Dell back on the phone, Install Open Manage Server Administrator so that you can see what the status of all array's and drives are.
