– 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 diskswill be 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 toconfigure a RAID 1 (mirrored) array after you have installed the operatingsystem, you will lose access to any data or applications that were previouslystored on the secondary 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 settingsfor attached devices.Starting the LSI Configuration Utility programUse this information to start the LSI Configuration Utility program.About this taskTo start the LSI Configuration Utility program, complete the following steps:Procedure1. Turn on the server.Note: Approximately 3 minutes after the server is connected to ac power, thepower-control button becomes active.2. When the prompt Setup is displayed, press F1. If you have set anadministrator password, you must type the administrator password to accessthe full Setup utility menu. If you do not type the administrator password, alimited Setup utility menu is available.3. Select System Settings → Adapters and UEFI drivers.4. Select Please refresh this page first and press Enter.5. Select the device driver that is applicable for the SAS controller in the server.For example, LSI Logic Fusion MPT SAS Driver.6. To perform storage-management tasks, see the SAS controller documentation,which you can download from the Disk controller and RAID software matrix:a. Go to http://www.ibm.com/systems/support/.b. Under Product support, click System x.c. Under Popular links, click Storage Support Matrix.ResultsWhen you have finished changing settings, press Esc to exit from the program;select Save to save the settings that you have changed.Chapter 3.
