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].
