Create empty custom Management Pack from SCOM via PowerShell

Found this one in my toolkit recently and thought I’d share. It’s a little old so the code could do with some optimizing..

What it does:

Prompts the script runner for a client number and then asks them to confirm the name for new management pack. If the operator types ‘yes’ (highly sophisticated coding) then a new management pack will be created with the desired naming convention

Our naming convention in this particular environment is to have all 3 client numbers at the beginning of the management pack name. As this is a multi-tenant environment it makes for easier identification.

Anyway, enjoy..
