Verify a DIMM

  1. Access Oracle ILOM.

    See Log Into Oracle ILOM (Service).

  2. Set the virtual keyswitch to diag so that POST will run in Service mode.
    -> set /SYS keyswitch_state=Diag
    Set 'keyswitch_state' to 'Diag'
  3. Reset the host so that POST runs.
    -> reset /System
    Are you sure you want to reset /System (y/n)? y
  4. Return the virtual keyswitch to Normal mode.
    -> set /SYS keyswitch_state=Normal
    Set 'keyswitch_state' to 'Normal'
  5. Start the Oracle ILOM fault management shell.
    -> start /SP/faultmgmt/shell
    Are you sure you want to start /SP/faultmgmt/shell
    (y/n)? y
  6. Check the event log.

    This example shows a faulty DIMM.
