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 Storage Controller restarts. Restarting a Storage Controller restarts the corresponding Management Controller. 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: If you restart both Storage Controllers, both Management Controllers will also be restarted so all hosts and users will lose access to the system and its data until the restart is complete. 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. Syntax restart sc|mc [a|b|both] [noprompt] Parameters sc|mc The controller to restart: • sc: Storage Controller • mc: Management Controller a|b|both Optional. The controller module containing the controller to restart. If this parameter is omitted, the command affects the controller being accessed. noprompt Optional in console format; required for XML API format. Suppresses the confirmation prompt, which requires a yes or no response. Specifying this parameter allows the command to proceed without user interaction. Example Restart the Management Controller in controller A, which you are logged in to: # restart mc a During the restart process you will briefly lose communication with the specified Management Controller(s). Do you want to continue? (y/n) yes Info: Restarting the local MC (A)... Success: Command completed successfully. (2012-01-21 11:38:47) From controller A, restart the Storage Controller in controller B: # restart sc b While the specified Storage Controllers restart, communication will temporarily be lost with the corresponding Management Controllers. Success: Command completed successfully. (2013-07-24 12:42:03) restart 127
