Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
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.
