RAID-1 drive failure / degraded.

Last Modified: 2020-02-04
I have an older Dell server that I am now responsible for.

The box is a Dell PowerEdge 2950 with a SAS 6/iR

It has two drive configured for RAID-1. One of the virtual drives is degraded. My only options on the tasks for that drive are blink and unblink. I was looking for a way to rebuild this drive. If I check on the Enclosure/physical disks in the openmanage server administrator, the problem drive's state is listed as Foreign with Failure predicted. The client has replaced this drive twice and we get the same notification.

On the alert log for that drive, there is the following description:
SAS port report: SAS wide port 0 lost link on PHY 0.: Controller 0 (SAS 6/iR Intergrated)
that's followed by
SAS port report: SAS wide port 0 restored link on PHY 0.: Controller 0 (SAS 6/iR Intergrated)
After my login to the openmanage server we get
(with a green checkmark)
A foreign configuration has been detected.: Control 0
Virtual disk degraded: Virtual Disk 0
Predictive failure reported: Physical Disk 0:0:0 Controller 0, Connector 0

predictive failure sounds like a failing / failed drive but two new drive in a row? Seems a little strange.

I'm not very versed in Raid controllers. Most times when I have an issue, I've replaced the failing drive, it rebuilt itself and life went on.

Any assistance on how to resolve this for the client would be greatly appreciated.

At this point I only have remote access to the server via RDP. I can get to it onsite if needed but that probably wouldn't happen until Monday.
