SCVMM 2012 R2 - Patching Machines and Clusters - Cluster Aware Updating

This following guide is based on the fact that your environment already has a WSUS installation somewhere (presumably on either an SCCM server or management server). Since SCVMM references WSUS, you can’t do much unless you’ve got WSUS installed somewhere.

Add in WSUS/SCCM update server:

Create a new baseline:

Search for whichever updates you need (server type/classification):

Highlight all the updates you want and click Add…

In the next window select an assignment scope (this can be done later though so you can always leave this blank if you're not sure what to pick):

The summary page will then give you a quick rundown of what you’ve selected:

Check the new baseline has been created:

Switch to the Fabric view. Drop down the cluster you applied the baseline to. Click on the Compliance button and you should be able to see your baseline:

At this point the compliance state will be unknown since the machine hasn't yet been scanned against the new baseline. To do this, highlight the machine and click Scan:

The Scan will then begin and should come back with a result:

In the above example the machine is fully compliant so there is no need to remediate. Were the machine to be missing updates, however, you would need to highlight the machine and click on the Remediate button. From here you can select which missing updates you want installed and whether you want to allow reboots. If you happen to be remediating an entire cluster in one shot you can also choose whether to live migrate the clients which reside on each host as SCVMM runs through the patching/rebooting.
