Stopping dedicated service tools

To stop dedicated service tools (DST), follow these steps.

1. If you do not want to see the displays for a manual initial program load (IPL), return the system to automatic mode. If you want to see the displays, leave the system in manual mode.
2. Press F3 until you return to the Use Dedicated Service Tools (DST) menu.
3. From the Use Dedicated Service Tools (DST) menu, select option 1 (Perform an IPL).
   Note: Do not perform an IPL if you are performing a complete system recovery. The system might take significantly longer than normal to complete the IPL. Some functions that you perform by using DST, such as starting mirrored protection, require the system to do additional work during the IPL before the system is available for your use.
