2 Select Auto Configuration and click Next. The Auto Configuration window appears. 3 On the next screen, select a redundancy option from the drop-down menu at the bottom of the Auto Configuration window: • No Redundancy: The new configuration will have no data redundancy (RAID 0). If a physical disk in the configuration fails, all data will be lost. • With Redundancy: The new configuration will have data redundancy, either by parity data (RAID 5 or RAID 6) or mirrored data (RAID 1). If a physical disk fails, its data is still protected. NOTE: The PERC 5/i controller supports RAID 0, 1, 5, 10, and 50, but it does not support RAID 6 or 60. The PERC 6/i controller supports RAID 0, 1, 5, 6, 10, 50, and 60. 4 Select an Initialization option from the drop-down menu at the bottom of the window: • No Initialization: The new configuration is not initialized and the existing data on the disks is not overwritten. • Fast Initialization: Dell SAS RAID Storage Manager quickly writes zeroes to the first and last 10 Mbyte regions of the new virtual disk and then completes the initialization in the background. This allows you to start writing data to the virtual disk immediately. • Full Initialization: A complete initialization is done on the new configuration. You cannot write data to the new virtual disk until the initialization is complete. This can take a long time if the disks are large. 5 Click Modify if you want to make changes to the Auto Configuration. For example, you could change the size of a virtual disk. To modify the configuration, perform the following steps: a Select a virtual disk in the New Virtual Disks panel. The Reclaim button becomes available. b Click Reclaim. A warning states that this will delete the newly created virtual disk. c Click Yes to accept. The array displays in the top left panel under the heading Arrays. Configuration 27
