Changing your system IPL from the control panel

You can specify the type of initial program load (IPL) you need to perform from the system control panel.

The Increment/Decrement buttons are used to change the IPL type and mode on systems without a mode button. Use Function 02 to select the IPL type (A, B, or D) and mode (normal or manual). To select the IPL type and mode from the control panel, follow these steps:
  1. Use the Increment/Decrement buttons to select Function 02, and press Enter.
  2. Use the Increment/Decrement buttons to select the IPL type and mode you want, and then press the Enter button to save.
  3. Optional: To specify a fast or slow IPL that can only be set one time at the console panel when the system is turned off, follow these steps:
    1. Select Function 02 and press Enter twice.
    2. Use the Increment/Decrement buttons to select F (Fast), S (Slow), or V (Value from IPL attributes).

The Hardware diagnostics IPL attribute determines the type of subsequent IPLs. *MIN is the preferred setting. However, if you anticipate any hardware problems, specify *ALL on the Hardware diagnostics parameter. Use the Change IPL Attributes (CHGIPLA) command to change the IPL attribute.
