10. Refer to the controller CLI reference guide to configure the controller.
NOTE: If the controller being installed was previously used in another subsystem, purge
the controller of the old configuration (refer to the CONFIGURATION RESET command
description in the controller CLI reference guide).
CAUTION: In step 11, 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.
11. Enable failover and re-establish the dual-redundant controller configuration with
one of the following commands:
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."
12. If desired, verify the failover configuration with the following command:
SHOW THIS_CONTROLLER FULL
13. Wait for FRUTIL to terminate, then reconnect all host bus cables to the "other
