How to Remove an Operations Manager Management Pack
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.
To remove a management pack
Log on to the computer with an account that is a member of the Operations Manager Administrators role.
In the Operations console, click Administration.
In Administration, click Management Packs.
In the Management Packs pane, right-click the management pack you would like to remove and then click Delete.
On the message stating that deleting the management pack might affect the scoping of some user roles, click Yes.
If any other imported management packs depend on the management pack you are trying to remove, the Dependent Management Packs error message displays. You must remove the dependent management packs before you can continue.
Operations Manager removes the selected management pack.
