For a detailed discussion of this procedure, see Uninitializing the System. POWER OFF SYSTEM UNINITIALIZE Shutting the controller down using the LCD menu Use the following procedure to select the Shutdown System display and execute a shutdown procedure. NOTE: Command View EVA is the preferred method for shutting down the controller. Shut down the controller from the OCP only if Command View EVA cannot communicate with the controller. Shutting down the controller from the OCP removes power from the controller on which the procedure is performed only. To restore power, toggle the controller's power switch. Enterprise Virtual Array 3000/5000 user guide (VCS 3. 1 10) 99 CAUTION: If you decide NOT to Power Off while working in the Power Off menu, the Power Off System NO option must be displayed before you press the ESC ( ) push-button to avoid power-down. to go to POWER OFF SYSTEM. Once you have selected the Shutdown System function, you can select and execute a shutdown method as described in the following sections. Restarting the system To restore the controller to an operational state, use the following procedure to restart the system. The system will automatically initiate the startup procedure and proceed to load the Storage System Name and Node WorldWide Name information from the operational controller. Powering off the system Use the following procedure to remove power from the controller pair, save the data, and remove the storage system from Command View EVA. NOTE: Implementing this procedure removes power from the controller pair and all associated drive shelves. To restore power to the controller system, you must cycle both PDU breakers in the enclosure. to scroll to Power Off. 100 Storage system hardware components 5. to select NO. Uninitializing the system Uninitializing the system is another way to shut down the system. Since Command View EVA cannot communicate with the disk drive enclosures, the stored data cannot be accessed. The WWN will remain in the controller unless both controllers are powered off. If the controllers remain powered on until you create another storage system (initialize via GUI), you will not have to re-enter the WWN. to accept NO Enterprise Virtual Array 3000/5000 user guide (VCS 3. 1 10) 101 Password options The password entry options are: · Entering a password during storage system initialization (see Setting Up an HSV1 10-Series Controller Pair Using the OCP). The actual password is not displayed, instead an indicator informs you of whether a password has been set. · Removing password protection (see Clearing a Password). Changing a password For security reasons, you may need to change a storage system password. First you must select a new, unique, eight-character password, using the uppercase letters A through Z and the lowercase letters a through z. After selecting the new password, use the following procedure to change the password. NOTE: Changing a system password on the controller requires changing the password on any Command View EVA with access to this system. To enter the first character, press either to scroll to CHANGE PASSWORD YES. [. . . ] The host computer sees the virtual disk as "real, " with the characteristics of an identical physical disk. See also active virtual disk, virtual disk copy, virtual disk family, and virtual disk snapshot. A clone or exact replica of another virtual disk at a particular point in time. A copy immediately becomes the active disk of its own virtual disk family. [. . . ]
