performs a restart on the specified
controller.

These commands will prepare the system to be restarted. The system will halt all I/O requests and
save the data to the disks before restarting. The restart process may take several minutes to complete.

shuts down the specified controller.
SHUTDOWN SUBSYSTEM

If you need to power down the InfiniteStorage 6120, use
SHUTDOWN
prior to shutting off the power.
This will cause the InfiniteStorage 6120 to immediately flush its cache, abort all initialization and
rebuild operations, and proceed with an orderly shutdown.
All hosts actively using the InfiniteStorage 6120 should be safely shutdown and all users logged out
before using this command. The InfiniteStorage 6120 will halt all I/O requests and save the data to
the disks. The unit can be safely turned off after using this command.
Once shut down is complete, all power supplies must be switched off or unplugged. Power must be
removed from the system for at least 10 seconds before it will start up again.
NOTE : Use SHUTDOWN whenever you need to power down the InfiniteStorage 6120
for maintenance. SHUTDOWN flushes any data left in the cache and prepares the
InfiniteStorage 6120 for an orderly shutdown.
