Set the initial program load (IPL) options from function
02 on the control panel. To permanently change the IPL speed use the
CHGIPLA command.
Note: Systems managed by the management console should use the management console to perform control
panel functions.
- Use function 01 to display the current IPL option, including IPL
speed. This is the option and speed that the system will use at the
next IPL.
- Use the HDWDIAG (hardware diagnostics) parameter
of the CHGIPLA command to permanently change the
IPL speed. The values are: The default shipped value *MIN (minimal)
for fast diagnostics and *ALL for all (full) diagnostics.
IPL speed recommendations
- Use CHGIPLA *MIN, or function 02 F or V=F for
most IPLs (to perform a fast IPL that uses minimum diagnostics).
- Use CHGIPLA *ALL, or function 02 S or V=S,
if you change hardware or suspect an intermittent hardware failure
(to perform a slow IPL that uses all diagnostics).
- Use CHGIPLA *ALL, or function 02 S or V=S during
the first IPL. You can set this at the panel with Function 02; it
affects only the one IPL because the next IPL will again pick up the
value set with CHGIPLA.
