When a ServeRAID boot CD is used on a machine is an LSI chipset a warning message is initially displayed implying that the card may be bad. This can be ignored; it is simply warning you that it cannot update the LSI firmware. The lowest version of ServeRAID controller firmware that can reliably be used in the x455 (also x455 and x382) is V6.10. At the time of writing there was an issue with flashing lower versions in these machine. The recommended way to upgrade the version of firmware is to put the controller in an IA-32 machine, flash it, then replace in the x455. For more information, see RETAIN® tip H18505: http://www.ibm.com/pc/support/site.wss/MIGR-53247.html The LSI Logic RAID-1 is not compatible with ServeRAID RAID-1. Therefore, if the operating system is installed on drives connected to the integrated LSI chipset, the operating system will need to be reinstalled should the customer decide to move to a ServeRAID adapter. For more information, see RETAIN tip H177072: http://www.ibm.com/pc/support/site.wss/MIGR-46174.html Booting from Fibre Channel At the time of writing, booting from a Fibre Channel-attached disk was not supported. 4.1.4 Flash update As part of your installation procedure, we recommend that you check the firmware levels and update to the most current revision. Typical components that may need upgrading are: System EFI/SAL (equivalent to BIOS on IA-32 systems) Onboard diagnostics Remote Supervisor Adapter Additional devices if installed, such as ServeRAID adapters and FAStT host bus adapters We recommend that you update both the EFI/SAL and Diagnostics at the same time if new versions are available for both. Always check the readme.txt file (the actual name is usually the same as the update executable) to check if there are any prerequisites.
