Change dead disk in DPM 2010
Solution 1:
The previous answer is nice when you have previous disk which is working and want to migrate on another and copy previous replica.
In the case you want to replace a failed hard disk I found a command to do that.
First, add the new disk to storage pool in administration tab and then remove the failed drive.
then start powershell dpm command and type :
DPMSYNC -Reallocatereplica
This will recreate replica on the new drive of the storage pool.
hope it help some.
Solution 2:
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].
