CLI Commands B–127
SET MULTIBUS_FAILOVER
Places “this controller” and the “other controller” into a dual-redundant
(failover) configuration within a multiple-bus environment. This allows
both controllers to access the storage devices and provide greater
throughput. If one controller fails, the devices and cache attached to the
failed controller become available to and accessible through the
remaining controller. Both controllers must be configured for nofailover
before you enter the SET MULTIBUS_FAILOVER command.
Note Partitioned storagesets and partitioned single-disk units cannot
function in multiple bus failover dual-redundant configurations.
Because they are not supported, you must delete your partitions before
configuring the controllers for multiple bus failover.
Syntax
SET MULTIBUS_FAILOVER COPY=controller
Parameters
controller
Specifies which controller (“this controller” or “other controller”)
contains the source configuration for the copy. The companion
controller receiving the configuration information restarts after the
command is carried out.
Caution Make sure you know which controller has the good
configuration information before entering this command. The device
configuration information from the controller specified by the
controller parameter overwrites the information on the companion
controller.
Specify THIS_CONTROLLER to copy the device configuration
information from the “this controller” to “other controller.”
Specify OTHER_CONTROLLER to copy the device configuration
information from the “other controller” to “this controller.”
