Maintenance and Service Guide
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
or
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.
