Temporarily isolate application server from farm for OS patching RRS feed

  • Question

  • I have a SharePoint 2010 farm:

    2 x WFE

    4 x Application

    1 x DB

    We have the two web front-end servers load balanced and have successfully patched the operating systems with Windows Updates. We successfully achieved this by temporarily disabling each WFE (one at a time) so that no production traffic could access the server being updated. this would allow us to work on the machine in isolation.

    We have reached our application servers, but because SharePoint manages the load balancing of the application servers in a farm we are unsure how to temporarily isolate an individual application server so that SharePoint doesn't use this to provide production responses.

    Question: What do we need to do to temporarily isolate/prevent SharePoint using an application server whilst it is having OS patches installed? Do we have to stop services on that server? Do we do this on the server, or through SharePoint Central Administration?

    Note: We are not installing SharePoint patches. We are only installing operating system patches.

  • Hi Chris.

    The only way for a SharePoint server to be fully isolated from the farm is to remove the server from the farm itself: this will prevent the SharePoint load balancer to include that server in the pool of targets for service applications' requests.
    You can temporarily stop the running services from the Central Administration (Search requires the corresponding service to be stopped from the Windows Services console too), patch the server and then restart the services.
