Install SharePoint Security Update on server in multiple servers farm RRS feed

  • Question

  • Hi

    I have production SharePoint 2013 farm with multiple SharePoint servers
    3 APPs servers
    3 WFE servers and they are load balancing.

    I plan to install SharePoint Security Updates on the servers and do it one at a time or at most, one WFE and one Application server at a time. 
    By doing this way,  I hope to be able to install SharePoint SU without causing a SharePoint services outage as much as possible.

    On my test farm, with only one App and one WFE,  when I install SharePoint SU update on WFE server,  SharePoint service does actually go down with "Service not available"  message.

    I don't have a multi servers test farm to check if my assumption is correct, so if anyone have done this on multiple servers or have information on installing SharePoint SU,  please advice.

    Thanks

  • Your app servers shouldn't be part of a load balancer, so those you can likely update without issue as long as your service apps/search is properly distributed across them.

    As for your FEs, yes do as you said -- bring a server out of the load balancer, patch, re-add.

    Don't forget you must run the Config Wizard on all of your servers. This will cause a farm-wide outage on the first server you run it but you can then use the load balancer technique with your FEs.
