Maintenance and Service Guide

H c. Clear invalid or failed cache conditions, if any exist. See Table 14

through Table 16 in the “Controller and Cache Replacement

Troubleshooting” appendix that starts on page 253 for more

information on clearing invalid or failed cache conditions.

Caution: Failure to clear an invalid cache message (especially a Cache is

FAILED message)

before

setting the Failover mode can result in a recursive

bugcheck error message that renders the controller unusable.

H d. Disconnect the PC or terminal from the maintenance port of the

controller associated with the replacement cache module.

 9. For the operational controller, complete the following substeps:

 a. Connect a PC or terminal to the maintenance port.

Caution: In substep 9b below, entering the appropriate SET command is

critical. Enabling an incorrect Failover mode can cause loss of data and incur

system downtime.

Verify the original failover configuration, and use the appropriate SET

command to restore this configuration.

 b. Re-establish the previous Failover mode by entering one of the

following commands:

SET FAILOVER COPY=THIS_CONTROLLER

SET MULTIBUS_FAILOVER

COPY=THIS_CONTROLLER

Note: After you enter the appropriate SET command, the controller restarts. A

controller restart can take as long as 60 seconds, indicated by the temporary cycling

of the port LEDs and a flashing Reset button.

The SET command copies the subsystem configuration from “this

controller” to the “other controller.”
