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.
