Verifying takeover by a standby controller

To verify that a standby controller can take over the functions of the controller, perform these actions:
  1. Stop the controller.
  2. Issue the following command: 
    MODIFY ssname,TAKEOVER
  3. Check that this message appears in the message log:
    Standby controller message 
    EQQZ129I TAKEOVER IN PROGRESS

When the standby controller has taken over the functions of the controller, more messages will appear in the message log. These are the same messages that appear when a controller is started. Verify that the takeover was successful by following the procedures used in the verification of the controller.
