Configuring a RAID array Configuring a SAS RAID array applies to a blade server in which two SAS hard disk drives are installed. Two SAS hard disk drives in the blade server can be used to implement and manage RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that are listed on the ServerProven list at http://www.ibm.com/servers/eserver/ serverproven/compat/us/. For the blade server, you must configure the SAS RAID using the LSI Configuration Utility program. If an optional BladeCenter Storage Expansion Unit 3 is installed, you can use it to control all of the SAS hard disk drives that are installed in the blade server. Enable this feature by using the Device and I/O Ports choice in Configuration/Setup Utility program (see Configuration/Setup Utility menu choices on page 40 for information and instructions). Using the LSI Logic Configuration Utility program You can use the LSI Logic Configuration Utility program to: v Set the SAS device scan order v Set the SAS ID for the controller v Manage the SAS RAID configuration To start the LSI Logic Configuration Utility program, complete the following steps: 1. Turn on the blade server, and make sure that the blade server is the owner of the keyboard, video, and mouse. 2. When the prompt is displayed, press Ctrl-C. 3. Use the arrow keys to select the controller from the list of adapters; then, press Enter. 4. Follow the instructions on the screen to change the settings of the selected items; then, press Enter.
