The installer will tell you whether or not the patch is applicable.Įdit: Since the original, I have added KB lists for 2008 R R2 based clusters.

The best way to test if patch/hotfix X needs to be installed is to try to install it.
This usually happens when updates are bundled together as a cummulative package or superseded by a new version. Be aware that some hotfixes have multiple KB numbers and may not show up even if they are installed. This script could easily be adapted to run against several servers at once, but I have to battle way to many internal firewalls to attempt such dark magic. It takes a list of hotfixes, and returns a list of the ones who are missing from the system. To simplify this process, I made the following powershell script. Luckily some are included in Microsoft Update, but some you have to install manually. Preferably one that is equal to the production system in every way possible.Īnyways, this results in having to check all my servers to see if they have the hotfixes installed. But then again, that is why cluster admins always fight for funding of a proper QA/T environment. That being said, sooner or later you will run across patches or hotfixes that will make a mess and give you a bad or very bad day. In my experience, hotfixes are at least as stable as regular patches, if not better. As a general rule, I recommend installing ALL hotfixes regardless of the attached warning telling you to only install them if you experience a particular problem. Some of them relate to a specific issue, while others are more of the go-install-them-at-once type. This list, as all such bad/good news comes in the form of a KB, namely KB2784261. From time to time, the good people at Microsoft publish a list of problems with failover clustering that has been resolved.
