“Unsealing” sealed management packs

April 14, 2010 Leave a comment

Sadly you cannot edit existing rules in sealed management packs. If you do want to change the scripts or any monitoring within a sealed management pack, the best practice here is to set an override against the items you need to customise (enable = false). And then recreate the two items in a custom management pack.

Although in theory you can break open a sealed management pack to make changes to the management pack, not surprisingly it isn’t a good idea. A seal is there for a reason. To show something hasn’t been tampered with. That it is genuine. Breaking open the sealed management packs to see how they function is a great way of learning. But don’t try and re-import (even if you do reseal it with your own seal) as:

1) Once you break the seal the packs are no longer supported.

2) You will not be able to upgrade the management pack. Jonathan Almquist gave a great explaination – “this is because you do not possess the key pair the vendor uses to seal their MP’s. Without the key pair, you can still seal the MP by generating your own key, but it will not match any key the vendor will use to seal future MP’s…which ultimately means you cannot download an updated MP from the vendor and just import. You’ll need to delete your overrides MP, delete the MP you now made your own, import the updated vendor MP, then recreate any overrides you had that targeted those classes in your ‘custom’ MP.”

Don’t do it!

Administrators that are new to OpsMgr can easily be lulled into a false sense of security and download Management Packs directly from the web from the administrator window in OpsMgr. I really don’t recommend it and Kevin Holman gave a great explanation of why it is not good practice on the Technet Forums.

Using this tool to directly import MP’s is a bad idea and a worst practice.

1. You need to manually download and read the guide FIRST.
2. You need to ensure you have handled any “before you import” activities from the guide.
3. The MP might include unsealed MP’s which are required, and unless this has changed – those do not come through the UI download.
4. The new MP might not be upgrade compatible with an existing MP in your environment and the UI will not tell you this.

I’d agree with Kevin in that what we need is a Management Pack notifier like we had in MOM 2005…. where it can generate alerts when an MP upgrade for an existing MP is avalable.
