Restart a system with logical partitions

To restart the whole system (perform a power down and an initial program load (IPL)) the secondary partitions must power down with the primary partition.

If you are going to restart the primary partition, first power down all of the secondary partitions.

You can restart a secondary partition without affecting the other secondary partitions. If the secondary partition is powered on, you can restart it using PWRDWNSYS OPTION *CNTRLD DELAY (600) RESTART (*YES). You can use this command from a command line at one of its workstations or use the Run Command in iSeries Navigator.
