Using the LSI Configuration Utility programUse the LSI Configuration Utility program to configure and manage redundant arrayof independent disks (RAID) arrays. Be sure to use this program as described inthis document. Use the LSI Configuration Utility program to perform the followingtasks:v Perform a low-level format on a hard disk drivev Create an array of hard disk drives with or without a hot-spare drivev Set protocol parameters on hard disk drivesThe integrated SAS/SATA adapter with RAID capabilities supports RAID arrays. Youcan use the LSI Configuration Utility program to configure RAID 1 (IM), RAID 1E(IME), and RAID 0 (IS) for a single pair of attached devices. If you install a differenttype of RAID adapter, follow the instructions in the documentation that comes withthe adapter to view or change settings for attached devices.In addition, you can download an LSI command-line configuration program fromhttp://www.ibm.com/systems/support/.When you are using the LSI Configuration Utility program to configure and managearrays, consider the following information:v The integrated SAS/SATA adapter with RAID capabilities supports the followingfeatures:– Integrated Mirroring (IM) with hot-spare support (also known as RAID 1)Use this option to create an integrated array of two disks. All data on theprimary 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. 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. 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 adapter treats them as if they allhave the capacity of the smallest hard disk drive.v If you use an integrated SAS/SATA adapter with RAID capabilities to configure aRAID 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 adapter, see the documentation that comeswith the adapter for information about viewing and changing settings for attacheddevices.Starting the LSI Configuration Utility programTo start the LSI Configuration Utility program, complete the following steps:1. Turn on the server.Note: Approximately 20 seconds after the server is connected to AC power, thepower-control button becomes active.116 IBM System x3400 M3 Types 7378 and 7379: Installation and User's Guide
