Appendix E Serial Attached SCSI BIOS Configuration Utility E-3
E.2 Starting the SAS BIOS Configuration
Utility
If you have SAS BIOS version 6.xx, and it includes the Fusion-MPT SAS BIOS
Configuration Utility, you can change the default configuration of the SAS host
adapters. You may decide to change these default values if there is a conflict
between device settings or if you need to optimize system performance.
The version number of the SAS BIOS appears in a banner displayed on the computer
monitor during bootup. If the utility is available, this message also appears during
bootup:
Press Ctrl+C to start LSI Logic Configuration Utility...
This message remains on the screen for about five seconds, giving you time to start
the utility. If you press Ctrl+C, the message changes to:
Please wait, invoking LSI Logic Configuration Utility...
After a brief pause, the computer monitor displays the Main menu of the Fusion-
MPT SAS BIOS Configuration Utility. These messages may appear during the boot
process:
■ Adapter removed from boot order!
This message appears when an adapter was removed from the system or was
relocated behind a PCI bridge.
■ Adapter configuration may have changed, reconfiguration is
suggested!
This message appears if none of the information in the NVRAM is valid.
■ Updating Adapter List!
This message appears when fewer than four adapters are in the boot order and
more adapters exist than are shown.
Caution – The SAS BIOS Configuration Utility is a powerful tool. If, while using it,
you somehow disable all of the controllers, press Ctrl+E (or Ctrl+A on versions
earlier than 5.00) after memory initialization during reboot to re-enable and
reconfigure the controllers.
Note – Some devices detected by the Configuration Utility cannot be controlled by
the SAS BIOS. Devices such as tape drives and scanners require that a device driver
specific to that device be loaded. However, the SAS BIOS Configuration Utility does
allow you to modify parameters for these devices.
