SET unit-number PREFERRED_PATH=THIS_CONTROLLER
b. Disable the CI bus paths with the following commands:
SET OTHER_CONTROLLER NOPORT_1_PATH_A
SET OTHER_CONTROLLER NOPORT_1_PATH_B
SET OTHER_CONTROLLER NOPORT_2_PATH_A
SET OTHER_CONTROLLER NOPORT_2_PATH_B
NOTE: The display of an error message, indicating that the subsystem was
unable to run down certain units on the “other controller,”is a timing issue. If
this occurs, repeat these SET commands.
3. Disable failover and take the controllers out of dual-redundant
configuration with one of the following commands:
SET NOFAILOVER
or
SET NOMULTIBUS_FAILOVER
4. Remove the program card ESD cover and program card from the
“other controller.”Save them in an antistatic bag or on a grounded
