Use this option to create an integrated mirror enhanced array of three to eight disks, including up to two optional hot spares. All data on the array disks will be deleted. - Integrated Striping (IS) (also known as RAID 0) Use this option to create an integrated striping array of two to eight disks. All data on the array disks will be deleted. v Hard disk drive capacities affect how you create arrays. The drives in an array can have different capacities, but the RAID controller treats them as if they all have the capacity of the smallest hard disk drive. v If you use an integrated SAS/SATA controller with RAID capabilities to configure a RAID 1 (mirrored) array after you have installed the operating system, you will lose access to any data or applications that were previously stored on the secondary drive of the mirrored pair. v If you install a different type of RAID controller, see the documentation that comes with the controller for information about viewing and changing settings for attached devices. Starting the LSI Configuration Utility program To start the LSI Configuration Utility program, complete the following steps: 1. Turn on the server. 2. When the prompt > is displayed, press Ctrl+C. If you have set an administrator password, you are prompted to type the password. 3. To select a controller (channel) from the list of adapters, use the arrow keys and press Enter. 4. To change the settings of the selected items, follow the instructions on the screen. If you select Raid Properties, SAS Topology, or Advanced Adapter Properties additional screens are displayed.

Formatting a hard disk drive Low-level formatting removes all data from the hard disk. If there is data on the disk that you want to save, back up the hard disk before you perform this procedure. Note: Before you format a hard disk, make sure that the disk is not part of a mirrored pair. To format a drive, complete the following steps: 1. From the list of adapters, select the controller (channel) for the drive that you want to format and press Enter. 2. Select SAS Topology and press Enter. 3. Select Direct Attach Devices and press Enter. 4. To highlight the drive that you want to format, use the Up Arrow and Down Arrow keys.
