Disabling Hardware

By using the configuration-policy command, you can disable

• A component--disables only the failing component

• A board---disables the board if any component on it fails

• A system--stops the system at the POST menu if there is a failure

Examples:

ok setenv configuration-policy board

or

# eeprom "configuration-policy=board"

To Disable a Defective Board

If you suspect a board is defective and want to request that the system disable the board, perform the following procedure.

1. Isolate the board from the system:

   • For a type three I/O board, use the setenv command at the ok prompt or the eeprom command at the # prompt and then reboot the system.

   • For all other boards, use DR commands.

   In the examples that follow, 3 means slot 3.

   ---

   ok setenv disabled-board-list 3
   

   ---

   or

   ---

   # eeprom "disabled-board-list"=3
   

   ---

2. Remove the defective board and insert a new board.

3. To activate the board:

   • For type 3 (PCI) I/O boards, clear the disabled-board-list, and then reboot the system.

   • For all other boards, use DR commands.

See Table 1-1 for more information.
