How to Remove an Operations Manager Management Pack

 

Updated: May 13, 2016

Applies To: System Center 2012 R2 Operations Manager, System Center 2012 - Operations Manager, System Center 2012 SP1 - Operations Manager

When you no longer need a management pack, you can delete it using the Operations console. When you delete a management pack, all the settings and thresholds associated with it are removed from System Center 2012 – Operations Manager. Also, the .mp or .xml file for that management pack is deleted from the hard disk of the management server. You can delete a management pack only if you have first deleted dependent management packs.

  1. Log on to the computer with an account that is a member of the Operations Manager Administrators role.

  2. In the Operations console, click Administration.

  3. In Administration, click Management Packs.

  4. In the Management Packs pane, right-click the management pack you would like to remove and then click Delete.

  5. On the message stating that deleting the management pack might affect the scoping of some user roles, click Yes.

When a management pack is deleted from the administration pane UI, it can become very time consuming to recursively track down and delete all dependent management packs before deleting the originally intended management pack. You can use the following script to cascade delete a management pack and all its dependencies.

To run the script, follow these steps:

  1. Open the Operations Manager Command Shell prompt in Administrator mode.

  2. Run the attached script from the directory where you have saved it in the disk. For example:

    • .\RecursiveRemove.ps1 <ID or System Name of the MP>

    • .\RecursiveRemove.ps1 Microsoft.SQLServer.2014.Discovery

    Note You can see the ID or System Name of the MP that you want to uninstall by selecting it in Installed Management Packs view. Then click Properties in the Actions Pane. Then copy the content in ID: text box in General tab.
