2–30 Replacement Procedures
8. Connect the trilink connectors with host bus cables (or terminators) to the new
controller.
NOTE: One or two trilink connectors with host bus cables (or terminators) may be
attached, depending on the configuration.
9. Press return to continue. FRUTIL will exit. If the other controller did not restart,
follow these steps:
a. Press and hold the other controller’s reset button.
b. Insert the other controller’s program card.
c. Release the reset button.
10. See HSZ80 ACS Version 8.3 Configuration and CLI Reference Guide to configure
the controller.
NOTE: If the controller you’ve installed was previously used in another subsystem,
it will need to be purged of the controller’s old configuration (see
HSZ80 ACS
Version 8.3 Configuration and CLI Reference Guide
).
11. Enable failover, and re-establish the dual-redundant controller configuration with
the following command:
SET FAILOVER COPY=THIS_CONTROLLER
This command copies the subsystem’s configuration from “this controller” to the
new controller.
12. Disconnect the PC or terminal from the controller’s maintenance port.
