Compaq HSZ80 manual Shutdown controller, 143

5–143

SHUTDOWN controller

Flushes all user data from the specified controller’s write-back cache (if 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.
