Restart - HP P2000 G3 Cli Reference Manual

restart

Description Restarts the Storage Controller or Management Controller in a controller module.
If you restart a Storage Controller, it attempts to shut down with a proper failover sequence, which
includes stopping all I/O operations and flushing the write cache to disk, and then the controller
restarts. The Management Controller is not restarted so it can provide status information to external
interfaces.
If you restart a Management Controller, communication with it is lost until it successfully restarts. If the
restart fails, the partner Management Controller remains active with full ownership of operations and
configuration information.
CAUTION:
data until the restart is complete.
NOTE:
reset; historical performance statistics are not affected. In a dual-controller system, disk statistics may
be reduced but will not be reset to zero, because disk statistics are summed between the two
controllers. For more information, see help for commands that show statistics.
