SET FAILOVER 2–59
HSZ40 Array Controller CLI Reference Manual
SET FAILOVER
__________________________ Note _____________________________
Both controllers must be in
NOFAILOVER
mode before you use the
SET FAILOVER
command.
____________________________________________________________
Places T
HIS
_
CONTROLLER
and the O
THER
_
CONTROLLER
into a dual-redundant (failover)
configuration. This allows both controllers to access the storage devices, providing higher
throughput. If one of the two controllers fails, the devices and cache (if any) attached to
the failed controller become available to and accessible through the operating controller.
Format
SET FAILOVER COPY=
configuration-source
Parameters
COPY=THIS_CONTROLLER
COPY=OTHER_CONTROLLER
_________________________Caution____________________________
The device configuration information from the specified controller will
overwrite the information on the target controller. Make sure you know which
controller has the good configuration information before entering this command.
____________________________________________________________

controller will restart when the command is completed.
Specify T
HIS
_
CONTROLLER

controller running the CLI session to the other controller.
Specify O
THER
_
CONTROLLER
to copy all the device configuration information from the
controller that is not running the current CLI session to T
HIS
_
CONTROLLER
(the controller
that is running the current CLI session).
Due to the amount of information that must be passed between the two controllers, this
command may take up to 1 minute to complete.
