Changing from Transparent Failover to Multiple-bus Failover

mode

Regardless of whether you have defined UNITs for the RAID system, the

following steps implement Transparent Failover to Multiple-bus Failover.

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 at the CLI prompt 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 will sound an alarm as it discovers the second

controller but detects that it is not bound in Failover mode. You can silence the

alarm and disregard the message about the controllers being misconfigured.

4. When the OTHER_CONTROLLER is online, enter the following command

to place the controllers into Multiple-bus Failover mode:

CLI> set multibus_failover copy=this_controller

This action copies all unit and connection information to the

OTHER_CONTROLLER and restarts both controllers.
