3.2.5.2System Shutdown
SHUTDOWN shuts down the controller unit.
If you need to power down the controller, use SHUTDOWN prior to shutting off power. This will cause the controller to flush its cache, abort all format and rebuild operations, and proceed with an orderly shutdown.
All hosts actively using the controller should be safely shutdown and all users logged out before using this command. The controller will halt all I/O requests and save the data to the disks.
NOTE : Use SHUTDOWN whenever you power down the controller for maintenance. SHUTDOWN flushes any data left in the cache and prepares the controller for an orderly shutdown. For couplet controller configuration, issue SHUTDOWN to both controllers.
To perform a hard restart of the unit by cycling the power, use: a value between 1 and 1023 seconds before the unit powers up default is 15 seconds.
SHUTDOWN RESTART=X, where X is again. If the number is not specified, the
NOTE : If SHUTDOWN RESTART is used in conjunction with the DUAL parameter, the restart will only affect unit where it was issued on and not both.
SHUTDOWN DELAY=X delays a shutdown of a unit between 0 and 255 minutes (where x is minutes delayed).
SHUTDOWN DUAL shutdowns both units.
SHUTDOWN KILL stops a timed shutdown that is in progress.
