Using the LSI Logic Configuration Utility program
Use the information in this section to configure an optional LSI RAID controller. If
you need to configure an optional ServeRAID controller, see "Configuring a
ServeRAID controller" on page 66.
Use the LSI Logic Configuration Utility program to configure and manage redundant
array of independent disks (RAID) arrays. Be sure to use the program as described
in this document. Use the LSI Logic Configuration Utility program to perform the
following tasks:
v Perform a low-level format of a SCSI hard disk drive
v View or change SCSI IDs for attached devices
v Set a SCSI device scan order
v Set SCSI protocol parameters on SCSI hard disk drives
v Configure arrays
v View your RAID configuration and associated devices
v Monitor operation of your RAID controllers
v Create a mirrored pair of SCSI hard disk drives with or without a hot-spare drive
The integrated SCSI controller with RAID capabilities supports redundant array of
independent disks (RAID) arrays. You can use the LSI Logic Configuration Utility
program to configure RAID level-1 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 SCSI settings for attached devices.
You can download an LSI command-line configuration program (CFG1030) from
http://www.ibm.com/systems/support/. For more information about the RAID
controller, go to http://www-304.ibm.com/jct01004c/systems/support/supportsite.wss/
docdisplay?lndocid=MIGR-65723&brandind=5000008 or complete the following
steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click Hardware upgrades.
3. Under Product family, click RAID.
4. Under Type, click on the type of RAID controller that is installed in your server.
When you use the LSI Logic Configuration Utility program to configure and manage
arrays, review the following information:
v The integrated SCSI controller with RAID capabilities in the server supports only
v When you create a RAID level-1 (mirrored) pair, all drives must be on the same

You must make sure that the primary drive has the lower SCSI ID (for example,
0).
