Sun Microsystems CP32x0 manual Starting the SAS Bios Configuration Utility

3.3Starting the SAS BIOS Configuration Utility

If you have SAS BIOS version 6.x.x with 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 has been removed from the system or has been 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 disable the controller, press Ctrl+E (or Ctrl+A on versions earlier than 5.00) after memory initialization during reboot to reenable and reconfigure the controller.

Note – The RAID firmware needs at least 64 Mbytes of unused disk space at the end of each drive to store metadata.
