13. Follow on-screen instructions to install the cache module

and to restart the “other controller.”

Note: A controller restart can take as long as 60 seconds,

indicated by the temporary cycling of the port LEDs and a flashing

Reset button.

Note: If the “other controller” did not restart:

a. Press and hold the “other controller” Reset button.

b. Reseat the “other controller” program card.

c. Release the Reset button.

Tip: To verify that the “other controller” restarts, connect a PC or

terminal to the maintenance port, and then verify that it passed the

cache diagnostic test.

Caution: In step 14, entering the appropriate SET

command is critical. Enabling an incorrect Failover mode

can cause loss of data and incur system down time.

Verify the original failover configuration, and use the

appropriate SET command to restore this configuration.

14. Enable failover and reestablish the dual-redundant

configuration with the following command:

SET FAILOVER COPY=THIS_CONTROLLER

SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER

This command copies the subsystem configuration from

“this controller” to the “other controller.”

15. If desired, verify the failover configuration with the

following command:

SHOW THIS_CONTROLLER FULL

16. Disconnect the PC or terminal from the controller

maintenance port.
