I am sure everybody has faced the challenge with patching clusters. In Windows Server 2012 we have the feature Cluster-Aware Updating to help us with applying software updates. Unfortunately if you use SCCM for patching you will probably continue using it even for 2012 clusters because you’ve already have some process in place and this new feature is no use, at least at first look. When you want to consolidate the work of two or more tools SC 2012 Orchestrator comes to the rescue. That is what Neil Peterson from MSFT have done and provided Cluster patching runbooks that leverage Windows Server 2012 Cluster and System Center 2012 Components. I haven’t tested them but feel free to test them and drop some comment here or in this page where you can download them..
