Turn off the system immediately

Stop the system by using the Power Down System (PWRDWNSYS) command on any command line when the system is in any mode.

Type PWRDWNSYS and press F4 to view the power down options. You must have QSYSOPR authority to use the Power Down System (PWRDWNSYS) command. If this command does not work on your system, use the following methods.

To turn off the system immediately:

  1. Type go power on any command line to display the Power on and Off Tasks (POWER) menu.
  2. Select option 3 (Power off the system immediately) if you want to keep the power off until the next time the system is scheduled to power on.
  3. Press F16 (Confirm) to confirm your choice to turn off the system immediately. An immediate shutdown occurs that causes the subsystems to end all active jobs.

To turn off the system and restart immediately:

  1. Select option 4 (Power off the system immediately and then power on) on the Power On and Off Tasks (POWER) menu.
  2. Press F16 (Confirm) to confirm your choice. The system stops running and then starts again automatically.
Note: Do not turn the modem on or off when the system is turned off and is made ready for remote initial program load (IPL). Otherwise, the system might start unexpectedly, although it turns itself off in a few minutes.

If you stop the system using the automatic power schedule or one of the options on the Power On and Off Tasks (POWER) menu, the IPL date and time system value (QIPLDATTIM) is checked and, if necessary, reset to the next scheduled power-on time. This checking does not occur if you turn off the system in another way, so the system might not turn on automatically. To force the power schedule to update the Date and time (QIPLDATTIM) system value, enter the following command on any command line: CHGPWRSCDE DAY(*TODAY) PWRONTIME(*SAME) PWROFFTIME(*SAME)
