Back up data on hard drives and access the Configuration Utility main screen. For details, see Logging In to the Configuration Utility.

Open the array configuration screen.

  1. On the displayed screen, select Array Configuration and press Enter.

    The Array Configuration screen is displayed, as shown in Figure 11-28.
