HP Array Controller HSG V8.7 Software - Manual (Page 400)

B–128 HSG80 User’s Guide
Due to the amount of information being passed from one controller to
the other, this command may take up to one minute to complete.
Example
This example shows how to configure two controllers to operate in
dual-redundant mode within a multiple bus environment:
SET THIS_CONTROLLER ID=(0,1,2,3)
RESTART THIS_CONTROLLER
SET MULTIBUS_FAILOVER COPY=THIS_CONTROLLER
The configuration on “this controller” is automatically copied to the
“other controller” when you issue the SET MULTIBUS_FAILOVER
COPY command. If you want to prefer specific units to specific
controllers, use the following command after setting multiple bus
failover:
SET D100 PREFERRED=THIS_CONTROLLER
SET D101 PREFERRED=OTHER_CONTROLLER
