IMMEDIATE_SHUTDOWN
NOIMMEDIATE_SHUTDOWN (default)
Instructs the controller when to shutdown.
CAUTION: The IMMEDIATE_SHUTDOWN 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 IMMEDIATE_SHUTDOWN to cause the controller to shutdown
immediately without checking for online devices or before flushing data from
the write-back cache to devices.
•
Specify NOIMMEDIATE_SHUTDOWN to cause the controller not to
shutdown without checking for online devices or before all data has been
flushed from the write-back cache to devices.
Examples
To shut down “this controller,” enter:
SHUTDOWN THIS_CONTROLLER
To shut down the “other controller,” even if the controller cannot write all of the
write-back cached data to the units, enter:
SHUTDOWN OTHER_CONTROLLER IGNORE_ERRORS
