present) and shuts down the controller. The controller does not
automatically restart. All units accessed through the failed controller
failover to the surviving controller.
Syntax
SHUTDOWN controller
Parameter
controller
Indicates which controller is to shut down. Specify
OTHER_CONTROLLER or THIS_CONTROLLER.
Switches
IGNORE_ERRORS
NOIGNORE_ERRORS (Default)
Controls the reaction of the controller based on the status of write-back
cache.
Caution The IGNORE_ERRORS switch causes the controller to keep
unflushed data in the write-back cache until it restarts and is able to
write the data to devices. Do not perform any hardware changes until
the controller flushes the cache.
Specify IGNORE_ERRORS to instruct the controller to shutdown even
if the data within write-back cache cannot be written to the devices.
Specify NOIGNORE_ERRORS to instruct the controller to stop
operation if the data within write-back cache cannot be written to the
devices.
IMMEDIATE_SHUTDOWN
NOIMMEDIATE_SHUTDOWN (Default)
Instructs the controller when to shutdown.
