You can schedule when a secondary partition will power on and power off by changing the IPL Date and Time (QIPLDATTIM) system value. You can change the QIPLDATTIM system value in Management Central in iSeries™ Navigator.
At a command line on a secondary partition workstation, use the GO POWER or CHGPWRSCD command to change a secondary partition power schedule.
When you schedule a secondary partition to power on, ensure that it is only during a time when the primary partition is already on. You have to power on the primary partition before you can power on any secondary partitions.
See Basic system operations for more information about power schedules.
