Using 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.v Use the LSI Configuration Utility program to perform the following tasks:– Perform a low-level format on a hard disk drive– Create an array of hard disk drives with or without a hot-spare drive– Set protocol parameters on hard disk drivesThe integrated SAS/SATA controller with RAID capabilities supports RAID arrays.You can use the LSI Configuration Utility program to configure RAID 0, RAID 1, andRAID 5 for a single pair of attached devices. If you install a different type of RAIDadapter, follow the instructions in the documentation that comes with the adapter toview or change settings for attached devices.In addition, you can download an LSI command-line configuration program fromhttp://www.ibm.com/supportportal/.When you are using the LSI Configuration Utility program to configure and managearrays, consider the following information:v The integrated SAS/SATA controller 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 plus up to twooptional hot spares. All data on the primary disk can be migrated.– 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.
