Modifying the Type of Start (DRAIN, DISABLE)
When you bring up z/VM®, CP reactivates the unit record devices
and displays that were active when you last shut down the system.
If you do not want to reactivate these devices, you can indicate that
you want CP to do one or both of the following:
- Suspend spooling activity to all of the unit record devices that are attached to the system
- Keep the displays that are attached to the system from being enabled.
Because CP does not restore spool files during a cold or clean start, you may want to keep the displays from being enabled. This gives you a chance to restore the files from tape before users log on and try to use the files.
