We’re all familiar with the Maintenance mode tool created by Ryan Andorfer, well Stefan Roth has created a utility for SCOM 2012 using the same look and feel. Well done Stephan.
I do need to note that this utility comes with a disclaimer to use at your own risk.
I’ve included the tool below, if you run into any issues or unexpected results the utility page is here leave Stephan a comment so he is aware of it.
