In some special cases, too - e.g. when testing new software, parameters or corrections - it may be necessary for system initialization to take place as far as possible without dialog. To this end, the parameter file may contain the deviations from the standard case and also the option of switching to a different mode once these presettings have been processed. The operator selects DIALOG mode from the SVP menu and, while in DIALOG mode, specifies the appropriate parameter file. By entering NEW-IPL-MODE=FAST under the keyword SYSOPT-IPL in the parameter file, systems support specifies that, once the parameter file has been evaluated, system initialization is to continue in FAST mode, i.e. unattended.
For information on the parameter record SYSOPT-IPL, see also section “Modifying the IPL options (SYSOPT-IPL)”.
