How to update a snconnector when one node has a higher revision in the MDC pair.  In this example we're SCPing the install file from node2 back to node1 and running the install script from /tmp/quantum on node1.

ssh to node1:
  mkdir /tmp/quantum
  cd /tmp/quantum
  scp stornext@<node2>:/var/www/html/connect-1.1.0/discover/content/snconnect_client-RedHat7_x86_64-16-27332626.tar.gz .
  tar -zxvf snconnect_client-RedHat7*
  ./snconnect_client/install_connector.sh <node2_metadata_ip_addr>
  ## This script is used to verify "snconnect_client" is version 16 from output of:
  /opt/quantum/connector/plugins/system/snconnect_client_version.py
