Remove Inactive Data Sources in DPM with PowerShell.

By Steven Jordan on 4/15/2014.

There are times when the DPM console GUI cannot remove its inactive data sources.  This PowerShell script removes all inactive data from DPM.  Choose between inactive disk or tape based data sources.

Removeinactivedatasource.ps1:

 

param([string] $DPMServerName, [string] $RemoveOption)

function Usage()
{
 write-host
     write-host "Usage::"

 write-host
 write-host "Run 'Remove-InactiveDatasource.ps1 -detailed' for detailed help"
 write-host

}

if(("-?","-help") -contains $args[0])
