All work after this point requires "root" privileges.When using RHEL5 supported Fibre Channel cards, this procedure is used for all OS architec-tures, and Fibre Channel card BIOS and driver versions.

2.1 Setting the Fibre Channel Cards BIOS Parameters

Procedure

1 Turn the server on, and watch for the QLogic BIOS boot message to be displayed, in order to confirm that the BIOS version specified in "Server Support Matrix" is installed.

If the BIOS version matches that specified in "Server Support Matrix", press the [Ctrl]+[Q]keys while the above message is displayed.

If the BIOS version differs from that specified in "Server Support Matrix", download andinstall the BIOS version specified in "Server Support Matrix" from the QLogic Corp web-site.
