Restarting and Shutting Down a Controller You can restart or shut down controllers when a controller is not working properly or when the system will be serviced or moved. Restarting a Controller You can restart one or both controllers when: ■ SMU informs you that you have changed a configuration setting that requires restarting ■ A controller does not seem to be working properly When you restart a controller, its Management Controller and Storage Controller processors are shut down and then restarted and any data in write-back cache is written to disk. Caution - If you restart the controller you are connected to, you lose access to the controller and you must reconnect to it and log back in to access SMU. If you restart both controllers, you lose access to SMU, CLI, and FTP and users lose access to data until the controllers have restarted. You must then log back in to access SMU. To restart a controller: 1. Select Manage > Restart System > Shut Down/Restart. 2. In the Restart Controller panel, select a controller option. 3. Click Restart. A confirmation prompt is displayed. 4. Click OK to confirm the operation or Cancel to stop it. If you clicked OK, a message indicates whether the operation succeeded. Note - If an iSCSI storage system is connected to a Microsoft Windows host, the following event is recorded in the Windows event log: A connection to the target was lost, but Initiator successfully reconnected to the target.
