9. Type the following and press Enter:
set multibus copy=this_controller
The controllers will restart in multibus mode. Wait two minutes for the
controllers to restart.
10. Verify that both controllers are configured for multibus failover mode by issuing
the following commands and viewing the results:
show this_controller
show other_controller
The controllers are now configured for multibus operation.
Preferring Storage Unit Paths
To complete the multibus configuration setup, you must assign storage units to one of
the controllers to specify which controller is used to access units at system boot time.
The preferred_path unit attribute assigns units to either “this” or the “other”
controller. In effect, this procedure specifies on which path (controller and/or host
bus adapter) the I/O will travel.
It is recommend that you initially balance the available storagesets between the
buses. As storage demands are defined and individual drive throughput requirements
are understood, adjustments to the disk I/O path configuration may be made using the
SANworks Secure Path Manager.
1. From the CLI window, enter the following command to obtain a list of all units
defined in the storage subsystem:
show units
2. Enter the following command to specify preferred_path for units:
set unit# preferred=this_controller
or
set unit# preferred=other_controller
