All data on the primary disk can be migrated.– Integrated Mirroring Enhanced (IME) with hot-spare support (also known asRAID 1E)Use this option to create an integrated mirror enhanced array of three to eightdisks, including up to two optional hot spares. All data on the array disks willbe deleted.– Integrated Striping (IS) (also known as RAID 0)Use this option to create an integrated striping array of two to eight disks. Alldata on the array disks will be deleted.v Hard disk drive capacities affect how you create arrays. The drives in an arraycan have different capacities, but the RAID controller treats them as if they allhave the capacity of the smallest hard disk drive.v If you use an integrated SAS/SATA controller with RAID capabilities to configurea RAID 1 (mirrored) array after you have installed the operating system, you willlose access to any data or applications that were previously stored on thesecondary drive of the mirrored pair.v If you install a different type of RAID controller, see the documentation thatcomes with the controller for information about viewing and changing settings forattached devices.Starting the LSI Configuration Utility programTo start the LSI Configuration Utility program, complete the following steps:1.
