Stop Transmissions to the First Platform Node

Be sure that the first Platform node will no longer have transmission requests routed to it.

1. On all Analytics nodes , edit /opt/msys/3rdParty/nginx/conf.d/momo_upstream.conf and either delete or comment out the line identifying the Platform node to be upgraded. For a combined cluster upgrade, perform this action on all nodes in the cluster .

   # Edit /opt/msys/3rdParty/nginx/conf.d/momo_upstream.conf
   
   #  In momo_upstream.conf, comment out the Platform node WHICH YOU ARE UPGRADING 
   #  from the upstream momo-rest stanza
        upstream momo-rest {
            server node1.int.messagesystems.com:2081;
            server node2.int.messagesystems.com:2081;
            server node3.int.messagesystems.com:2081;
          least_conn;
      }
   

   Reload the NGINX configuration.

   pssh -h /var/tmp/vertica-hosts-file "/etc/init.d/msys-nginx reload"

2. Allow the node time to finish generation.
