    Hi guys,

    I am trying to stop and delete a Protection Group (DPM 2012) but the Stop Protection window that opens up lists the results as 'Performing' - it has been like this for a few days now and none of them are changed status.

    Is there something I can check to see why this is happening and remove protection from this group?
    Please let me know if there is any other information I can provide.

    FYI The server is not using all of its resources.

    Any help would be greatly appreciated.


    Regards,
    Locust12

    Hi Locust12,

    Could you try with powershell script:

    First, verify that your PG is present :

    Get-ProtectionGroup -DPMServerName $env:computername

    Then try to delete it with this script:

    (Replace YourStringSearch with your PG Name).

    Connect-DpmServer $env:COMPUTERNAME
    $StringSearch="YourStringSearch"
    $PgList = @()
    $pgList = Get-ProtectionGroup -DPMServerName $env:computername
    where {($_.friendlyname) -match $StringSearch}
    foreach($Pg in $PgList){
    write-host ""
    Write-host "# ProtectionGroup Name " -ForegroundColor red -Nonewline
    Write-host $Pg.FriendlyName -ForegroundColor green
    $mpg = Get-ModifiableProtectionGroup $Pg
    $dsList = @()
    $dsList = Get-DataSource -ProtectionGroup $Pg
    foreach($ds in $dsList){
    write-host ("Remove data source ",$ds.Name)
    Remove-ChildDataSource -ProtectionGroup $mpg -ChildDataSource $ds -keepDiskData
    }
    Set-ProtectionGroup $mpg
    }
    Disconnect-DpmServer $env:COMPUTERNAME

    Does it work ?

    Hi Stephane,

    Thanks for the reply.

    When I run the Get-ProtectionGroup -DPMServerName $env:computername I can see the PG in question - "Production Applications"

    However when I run the script (substituting YourStringSearch for Production Applications) it starts removing data source of a different PG. It has not completed removing the data sources and seems stuck.

    Looking forward to your reply.

    Regards,

    Hi Locust12,

    This is strange...

    Could you please run this script to see if your PGs and your Datasources are healthy :

    Disconnect-DpmServer $env:COMPUTERNAME
    Connect-DpmServer $env:COMPUTERNAME
    $StringSearch="YourStringSearch"
    $PgList = @()
    $pgList = Get-ProtectionGroup -DPMServerName $env:computername ## where {($_.friendlyname) -match $StringSearch}
    foreach($Pg in $PgList){
    write-host ""
    Write-host "### ProtectionGroup Name " -ForegroundColor red -Nonewline
    Write-host $Pg.FriendlyName -ForegroundColor green
    write-host ("ProtectionGroup Name ",$PG.Name)
    write-host ("ProtectionGroup FriendlyName ",$PG.FriendlyName)
    write-host ("ProtectionGroup ProtectionGroupId ",$PG.ProtectionGroupId)
    write-host ("ProtectionGroup IsPGDisconnected ",$PG.IsPGDisconnected)
    write-host ("ProtectionGroup PGProtectionType ",$PG.PGProtectionType)
    write-host ("ProtectionGroup ProtectionMethod ",$PG.ProtectionMethod)
    $dsList = @()
    $dsList = Get-DataSource -ProtectionGroup $Pg
    foreach($ds in $dsList){
    write-host "# DataSource Name " -ForegroundColor blue -Nonewline
    write-host $ds.Name -ForegroundColor yellow
    write-host ("DataSource Protected ",$ds.protected)
    write-host ("DataSource State ",$ds.State)
    }
    }
    Disconnect-DpmServer $env:COMPUTERNAME

    Hi Stephane,

    When running that script I can see the PG'S in question but some of the datasource states are marked as invalid.

    Hi,

    You should take a look in MSDPMCurr.errlog in the "C:\Program Files\Microsoft System Center 2012\DPM\DPM\Temp" folder to find possibly more details.

    Search for this string:

    <FriendlyName>YourPGName</FriendlyName>
    <PGSetId>00000000-0000-0000-0000-000000000000</PGSetId>
    <MarkedForDeletion>true</MarkedForDeletion>

    Your datasources will be listed below.

    Stephane

    Hi Stephane,

    I am unsure why but my colleague was able to do the exact same task via the GUI but with a successful result.
    We are currently recreating this PG.

    Thanks for your assistance and hopefully smooth sailing again from here.
