v If you install a different type of RAID controller, see the documentation that comes with the controller for information about viewing and changing SCSI settings for attached devices. Important: If you use the integrated SCSI controller with RAID capabilities to configure a RAID level-1 (mirrored) array after you install the operating system, you will lose access to any data or applications that were previously stored on the secondary physical drive of the mirrored pair. Using the LSI Logic Configuration Utility program The LSI Logic Configuration Utility program is a built-in, menu-driven configuration utility program that you can use to: v Perform a low-level format of a SCSI hard disk drive v Set a SCSI device scan order v Set a SCSI ID for a controller Notes: 1. The integrated SCSI controller with RAID capabilities in your server supports only RAID level-1. Installing an optional RAID adapter provides additional RAID levels. See "Using ServeRAID Manager" on page 22 for information on configuring your server for RAID operation. 2. If you install a different type of RAID adapter in your server, use the configuration method supplied with the RAID adapter to view or change SCSI settings for attached devices. The following sections provide instructions for starting the LSI Logic Configuration Utility program and formatting a SCSI hard disk drive. Starting the LSI Logic Configuration Utility program Complete the following steps to start the LSI Logic Configuration Utility program: 1. Turn on the server. 2. When the prompt > appears, press Ctrl+C. If you have set a supervisor password, you are prompted to type the password. 3. Use the arrow keys to select a controller (channel) 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. If you select Device Properties or Mirroring 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. Formatting a SCSI hard disk drive Low-level formatting removes all data from the hard disk. If there is data on the disk that you want to save, back up the hard disk before performing this procedure. Note: Before you format a SCSI hard disk, make sure that the disk is not part of a mirrored pair. From the list of adapters, select the controller (channel) for the drive that you want to format. Select Mirroring Properties and make sure that the mirroring value for the drive is None. Chapter 2. Configuring the server 21
