Change dead disk in DPM 2010

I was backuping data on an 1Gb hard drive with DPM 2010. This disk died but I replace it with another 1Gb hard drive.

But I don't find how to recreate data structure on this new drive from previous protection group.

Protection group were red. I delete the disk in "administration > disks", now protection group are green but they don't save data and I can't see any menu to change the disk destination.

how to do ?

thanks

• I believe this will work:

  1. Under Management -> Disks tab, add the new disk.
  2. Under Protection -> Right click the protection group, Modify Disk Allocation

  DPM Disk(s) should be redundant; DPM's D2D backup wasn't designed for very small environments where you have a single non-redundant disk.

  Dragouf : I tried that but I can't do nothing in this window. Even if the new disk is present under "Management -> Disks tab". here is the screen shot of the "Modify Disk Allocation" window (the ui is in french) : http://img189.imageshack.us/img189/8494/capturehnc.png

• You will need to use the MigrateDatasourceDataFromDPM.ps1 PowerShell command in the DPM shell. More details on the command are available on Techent - http://technet.microsoft.com/en-us/library/ff399384.aspx

  The command would be similar to this:

  $disk = Get-DPMDisk –DPMServerName DPMTestServer 
  ./MigrateDatasourceDataFromDPM.ps1 –DPMServerName DPMTestServer –Source $disk[0] –Destination $disk[1]
  

  However, I would first run get-dpmdisk -dpmservername myserver to determine which disks you are going to use. For example, first disk listed would be $disk[0] in the above command, and the third disk would be $disk[2].
