Control panel function codes on the Hardware Management Console

Control panel function codes are used to indicate status and function options for a system that is managed by a Hardware Management Console (HMC).

If you are managing the system with the HMC, use the HMC to perform control panel functions. Servers without physical panels require the HMC to perform the equivalent control panel functions. The HMC affects the physical control panel in the following ways:
  • Except for some limited automatic platform override functions, such as automatic power-on restart and timed power-on functions, the system operating mode value no longer has meaning.
  • The operating system IPL-type value is disabled in functions 01 and 02.
  • Functions 11 - 19 do not display partition system reference codes (SRCs). They continue to display SRCs from the platform Licensed Internal Code.
  • Functions 21, 22, 34, and 65 - 70 are not selectable on the physical control panel.
The following table lists the control panel functions that you can perform on the HMC.
