We have had this issue before as well, it seems that Tao provides an override pack with it but some users choose to create their own override pack.

When doing this SCOM automatically adds a reference to Tao’s management pack which contains an invalid alias. After some investigation it seems that Tao has posted the following workaround. Information on this can be found here, http://blog.tyang.org/2013/03/03/opsmgr-self-maintenance-management-pack/ :

  1. Export the management pack containing the overrides to the self-maintenance MP
  2. Open the .xml file in Notepad
  3. Add a reference to the self-maintenance MP inside the <References> section as follows. You’ll need to enter the version number of Tao’s pack that you’re using under the <Version> field below:

<Reference Alias=”OM12SelfMaint”>
<ID>OpsMgr.2012.Self.Maintenance</ID>
<Version>2.5.0.1</Version>
<PublicKeyToken>136b1dfd385ca82a</PublicKeyToken>
</Reference>

  1. Save the file & re-import the management pack into SCOM.

I hope this helps!
