Confirm that the scenario works by previewing the updates and prompting a Self-Updating Run Then you simply sit back and enjoy watching cluster self-updating in action! As Failover Clustering Tools are by default auto-selected for installation when the Failover Clustering feature is installed on a cluster node, your cluster nodes most likely already have CAU tools pre-installed.
The net is that you can safely skip this step if you are running it from one of the cluster nodes.
At a high level, there are three things you need to do to get the end-to-end scenario working and operating seamlessly with your existing patching infrastructure such as Windows Server Update Services (WSUS), on a Windows Server 2012 failover cluster: 1.
Install CAU tools on the Windows Server 2012 (or Windows 8 Client) computer that you want to run it from. Configure self-updating on the desired failover cluster 3. Install CAU tools Installation of CAU is very easy: CAU tools are a part of Failover Clustering Tools.
The nice aspect of this design is that CAU self-updating is a clustered service in its own right, that is highly available.
You always start off by connecting to a cluster as in the following screen shot: Look at the two highlighted areas in red in the above screen shot – you can type in the desired cluster name, and hit the “Connect” button right next to it.
You of course can also click the down-arrow right next to the cluster name text box, which will show all the available cluster names, as known to local AD.
If you had of course explicitly chosen not to install Failover Clustering Tools on the cluster nodes, you will need to install them now with this step.
If you plan to run CAU from a computer different from the cluster nodes, that is still easy!
