Switching the Lancelot 4200-SS LSI controller to IT Mode

Description:

A small number of Lancelot 4200-SS systems shipped with the standard LSI HostRAID firmware. This firmware causes the controller to not be supported by the standard LSI driver in the Linux kernel.

We now have a new LSI firmware for this system that will allow it to work with the standard driver that ships with CentOS/RHEL. If this firmware is installed, it is no longer necessary to use any driver disks.

!!! WARNING !!!

Upgrading this firmware will destroy any existing data on the disks. The firmware update CD can be downloaded here:

ftp://ftp.aslab.com/pub/bios/lsi/lsi_x7qc3.iso

After burning the CD, follow these steps to upgrade the firmware:

  1. Turn off the system
  2. Remove the top cover
  3. Move jumper JPS2 to the OFF position. This jumper should be located in the front left corner of the motherboard by the round battery.
  4. Boot the system from LSI firmware CD
  5. Type the following command to retrieve the address of the SAS adapter: 
    A:\> mptutil -q

    Write down the 16 digit address. It will be used later.

  6. Clear the existing firmware: 
    A:\> clear.bat
  7. Power cycle the system and boot from LSI firmware CD
  8. Install the new firmware 
    A:\> x7qc3.bat
  9. When prompted, enter the 16 digit SAS address recorded earlier
  10. Reboot.

You should now be able to install CentOS without a driver disk.
