    You can just stop the  3rd jvm  and remove it form the plugin( if you have one). Or change the weight on the 3rd jvm to zero.

    Hope that helps!

    Hi Sivaram,

      In addition to previous suggestions, if the objective is f.e a limited outage of the server for maintenance purpose. You can put the third JVM in backup server role, the plugin automatically will redirect all the requests to other two cluster members. You only need to change the role and propagate the plugin
     
      To take in mind with this approach: you need to be sure that the other cluster members health is good and that they can take all the workload.

      I have used this approach in many clients.
     
      Hope this helps. Tell us if you need more support.
     
     Regards
