HSG80 Controller Failover Transitions

Changing from Transparent Failover to no failover mode

1. Enter the following command at the CLI prompt:

CLI> set nofailover

This action causes the OTHER_CONTROLLER to shut down.

2. Enter the following command to verify the change to no failover.

CLI> show this_controller

3. Restart the OTHER_CONTROLLER by pressing the RESET button on the

OTHER_CONTROLLER.

The OTHER_CONTROLLER sounds an alarm as it discovers the second

controller but detects that it is not bound in a failover mode. You can silence

the alarm and disregard the message about the controllers being

misconfigured.

Enter the following command to verify the change in controller state:

CLI> show this_controller

Note: This state change is important only if a controller is to be replaced, or if the state

is changing from Transparent Failover to Multiple-bus Failover or vice-versa. This is not

an ending state in itself.
