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 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 configu-
ration information before entering this command. The device configura-
tion 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.”
