Adding References to MPs in SCOM 2012 with PowerShell

This is a continuation of a Data Center Automation series of posts that I have been working on with Anders Bengtsson. Here are the first six posts in this series:

Creating Management Packs in SCOM 2012 with PowerShell
Creating Performance Collection Rules in SCOM 2012 with PowerShell
Creating Event Based Alerting Rules in SCOM 2012 with PowerShell
Enabling or Disabling Workflows in SCOM 2012 with PowerShell
Deleting Workflows in SCOM 2012 with PowerShell

As of this post this script is not included as an activity in the Operations Manager Admin Integration Pack but will be in the next version.

Syntax:

.\AddReference.ps1 –ManagementServer ‘om01.contoso.com’ –ManagementPackID ‘custom.example.test’ –MPPath ‘c:\temp\MyMP.mp’ –Alias ‘MyMP’

Parameters:

  1 Param(
