How to import CentOS MP

So far, CentOS MP cannot directly download from the catalog manager of SCOM, but it is possible to download and import to SCOM in another way. I'm going to explain that how to download, modify, seal and import these CentOS MPs. 


1. Download CentOS MPs from here. They're not sealed but xml types. There are five files after upzip. We need only two file which contain "centos" in their names. 

Cenos-library (short for "Microsoft.Linux.CentOS.Library.xml") should be the first to import because Cenos-5 (short for "Microsoft.Linux.CentOS.5.xml") has dependency of the Cenos-library. 


I tried to import these xml typed MP files to SCOM console, but they were failed. (Centos-library imported well but Centos-5 had problem.)



this error was that it couldn't find dependency about this pack. I changed my mind that I made sealed MPs. I intended that I could find the way easier to solve the dependency problem. A benefit of this is that I can get specific error messages during sealing, for example, knowing easily whether some dependent MP is wrong or not - it could have wrong version or wrong publicKeyToken

2. Make KeyFile for the MP.

c:\>sn -k c:\MpForCentos\pairkey.snk

I made a folder named "MpForCentos" and copied mp files, then made keyfile into this folder.

3. Seal MPs

I ran the command prompt program and typed commands for sealing Centos-library like below.

C:\MpForCentos>c:\SupportTools\amd64\mpseal Microsoft.Linux.CentOS.Library.xml /

keyfile pairkey.snk /company "cubecore"

However, I got errors.

At first, I copied mp files which showed in error message to my folder. And I checked the version of MPs that actually had been imported to SCOM. after that I found that Centos-library has the wrong version of two dependent MPs. (I remembered that I once updated cross platform MPs, the latest version are 6.1.7000.277. )

I edited Centos-library.



After modify values, tried to seal it again, Centos-library imported fine to SCOM.


As the next step, It remained to seal Centos-5.
Keep in mind that the a value have to be changed before make it seal. 
You would get error if you import Centos-5 seal without change value related Centos-library in its xml. 


As I mentioned above, Centos-5 has dependency of Centos-library and I made the first sealed MP by using keyfile. So publicKeyToken of Centos-library has been changed. I cloud get PublicKeyToken by execute the following command.


C:\MpForCentos>sn -T Microsoft.Linux.CentOS.Library.mp


Edit the file Microsoft.Linux.CentOS.5.xml by entering the PublicToken Key at the reference for Linux.CentOS.Library MP



Finally, it imported well.
