Parameters
[a|b|both]

controller has restarted.
Examples Restart the Management Controller in controller A, to which you are logged in.
# restart mc a

shutdown
restart sc
Description Restarts the Storage Controller in a controller module.
When 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
Storage Controller restarts. Restarting a Storage Controller restarts the corresponding Management
Controller.
CAUTION:
● Depending on the mapping configuration, restarting one Storage Controller may
cause loss of access to data.
● If you restart both Storage Controllers, all hosts will lose access to the system and
its data until the restart is complete. Additionally, both Management Controllers will
be restarted and all users’ sessions will need to be restarted.
NOTE: When a Storage Controller is restarted, live performance statistics that it recorded will
be 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.
