 5. For the operational controller, complete the following substeps:
 a. Connect a PC or terminal to the maintenance port of the operational
controller.
Caution: In substep 5b below, entering the appropriate SET command is
critical. Enabling an incorrect Failover mode can cause loss of data and incur
system downtime.
 b. Restore the Failover mode and re-establish the dual-redundant
controller configuration with one of the following commands. For
example, if you noted that the Failover mode in substep 1c on
page 122 was Multibus, enter the second command below.
SET FAILOVER
COPY=THIS_CONTROLLER
or
SET MULTIBUS_FAILOVER
COPY=THIS_CONTROLLER
The above commands copy the subsystem configuration from the
operational controller to the controller that failed or is being replaced.
 c. Verify that the replacement controller restarts and that the cache for
both the operational and replacement controller is good by entering
the following commands:
SHOW THIS_CONTROLLER
SHOW OTHER_CONTROLLER
Note: See Table 14 through Table 16 in the “Controller and Cache Replacement
Troubleshooting” appendix that starts on page 253 if the cache is not good.
Note: The replacement controller can fail with a recursive bugcheck (OCP code 25),
and the Reset button LED remains steady on. Contact HP technical support or replace
the controller if this condition occurs.
