Use this option to create an integrated array of two disks plus an optional hot spare. All data on the primary disk can be migrated. - Integrated Mirroring Enhanced (IME) with hot-spare support (also known as RAID 1E) Use this option to create an integrated mirror enhanced array of three to eight disks, including an optional hot spare. - 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 disk 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 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 SAS settings for attached devices. Using the LSI Logic Configuration Utility program Use the LSI Logic Configuration Utility program to perform the following tasks: v Perform a low-level format of a SAS hard disk drive v Create an array of SAS hard disk drives with or without a hot-spare drive v Set SAS protocol parameters on SAS hard disk drives The integrated SAS controller with RAID capabilities supports RAID arrays. You can use the LSI Logic 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 different type of RAID adapter, follow the instructions in the documentation that comes with the adapter to view or change SAS settings for attached devices. The following sections provide instructions for starting the LSI Logic Configuration Utility program and performing selected functions. Starting the LSI Logic Configuration Utility program To start the LSI Logic Configuration Utility program, complete the following steps: 1. Turn on the computer. 2. When the prompt > appears, 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. When you have finished changing settings, press Esc to exit from the program; select Save to save the settings that you have changed. 26 IBM IntelliStation Z Pro Type 9228: User's Guide
