DPM error Volume missing

Standard

Have you’ve ever had a Monday where you thought everything would be unicorns and rainbows? I thought I had one this week but unfortunately I got the following error message in DPM “Volume missing”.

My good mood buzz was gone and I was not amused. I’ve dealt with this kind of errors before and I know this can be a hell of a job to fix.

The steps to fix this issue is twofold. First you need to rescan the disks on the DPM server and second you need to rescan every disk in DPM.

1. Rescan the disks on server

Go to Start, click on run and type in “diskmgmt.msc”

Click in the top menu on “Action” and click “Rescan Disks”

Just wait and relax while you see the screen below. When the screen disappears the action is complete.

2. Rescan the disks in DPM

In the DPM Administrator Console click on the management tab.

Click on the tab “Disks” which will show you a screen similar to the one below.

Right-click on the first disk in the list and click on “Rescan”.

Just sit back and relax while the screen below appears.

When the screen disappears repeat the action for the next disk. Unfortunately Microsoft hasn’t thought of a bulk action to finish this task so if you have a lot of disks as it was the case in my situation, get a cup of coffee and start scanning disks for about an hour.

TIP
De details screens below shows the protected data sources  which are present on the disk. You don’t have to rescan all the disks if you know which disk which holds the datasource which failed.
