How to remove System Center Operations Manager Management Packs with references to unsealed MPs?

For the most part removing Management Packs (MP) is a quick administrative process done in the OpsMgr console, which is as follows:


1.       In the OpsMgr Console


2.       Administration -> Management Packs


3.       For each XXXX MP -> Right Click -> Delete


However occasionally there have been issues where people have setup references to other unsealed MPs and it can be time consuming to remove all the override references and you don't want to delete the entire Management Pack. Secure Vantage Technologies has released a tool that you can use to remove override references from the MP you are trying to remove.

Steps to delete an MP when you can't due to override references in unsealed MPs.


1.       Download the InstallTool.exe provided by Secure Vantage Technologies from http://www.securevantage.com/Products/Utilities/InstallTool.zip

2.       Run the InstallTool.exe -ea (Backs up all unsealed MP to C:\Program Files\System Center Management packs\MP Backsup\\* )

3.       Run the InstallTool.exe -rr SecureVantage.Security (this example removes all references to Secure Vantage MPs from unsealed MPs, must use prefix of MP ID)

4.       Review the log file created for details on next steps

Once the overrides are removed you are still be required to manually remove the MP manifest reference by editing the XML directly.

5.       Export the Management Pack in question and open the file in a text editor

6.       You will need to remove any reference in the manifest, here is an example of what you will be removing in the case of Secure Vantage MPs.
