      <br>
      Is it possible to trigger some... action - I'm thinking
      specifically at shutdown/start.<br>
      If not within the cluster then - if you do that - perhaps outside.<br>
      I would like to create/remove constraints, when cluster starts
      & stops, respectively.<br>
      <br>
      many thanks, L.<br>
    </font>
