Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
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_FAILOVERCOPY=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.”
