<<You can shut down PSMON as follows:

:SYSDIAG
DUI>DIAGSYSTEM SHOWACTIVE (NOTE PSMON PIDNO)
DUI>DIAGSYSTEM ABORT PIDNO (AS NOTED ABOVE)

To restart PSMON,

DUI>DIAGSYSTEM RUN SMON>>

Do these non-Predictive machines have PSCONFIG.PRED? The "normal" way to
shut down PS is
:run psconfig.pred.sys;info="stop"

and similarly with 'info="run"' to start it up. Or run PSCONFIG
interactively.
