Specifying a Clean Start

When the system is reloaded, CP prompts you for the type of start you want to perform. CP issues the following prompt:

Start ((Warm|Force|COLD|CLEAN) (DRain) (DIsable) (NODIRect) (NOAUTOlog))
      or (SHUTDOWN)

Specify a clean start by entering:

clean

This response causes CP to perform a clean start. When clean start is selected, you receive the following prompt:

CLEAN start has been selected.  This will cause all
spool files and System Data Files (NSS, DCSS, TRF, IMG,
UCR, NLS) to be deleted.

No files have been deleted yet.
To continue CLEAN start and delete files, enter GO.
To stop CLEAN start without deleting files, enter STOP.

You must now decide whether to continue system initialization (deleting the indicated files) or to stop system initialization (without deleting any files).

To continue system initialization, enter:

go

To stop system initialization, enter:

stop

Attention: The clean start procedure purges:

All spool files
All system data files
All accounting, EREP, and symptom records in storage
The system log message.

A clean start is desirable in the following scenarios:

IPLing after replacing existing spool volumes with new volumes.
First time IPLing with a new warmstart area defined (spool file recovery information is stored in the warm-start area).
You do not want to restore previously existing system data files.
