HP Array Controller HSG V8.7 Software - Manual (Page 391)

CLI Commands B–119
SET FAILOVER
Configures both controllers to operate in a dual-redundant, transparent
failover, configuration. This allows both controllers to access the
storage devices, providing controller fault-tolerant data processing. If
one of the two controllers fails, the devices and any cache attached to
the failed controller become available to and accessible through the
other controller.
Note The controllers must be present and placed in non-failover mode
by entering the SET NOFAILOVER command before they can be set
to failover mode.
Syntax
SET FAILOVER COPY=controller
Parameters
THIS_CONTROLLER
OTHER_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
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 “this controller” to “other controller.”
Specify OTHER_CONTROLLER to copy the device configuration
information from “other controller” to “this controller.”
Due to the amount of information being passed from one controller to
the other, this command may take up to one minute to complete.
