. To determine if a secondary partition
has been configured to
″
Hold
″

This ends the procedure.
Powering On a Secondary Partition
Attention: Powering on a secondary partition will not power on any expansion
I/O towers that the logical partition owns. If it is necessary to power on expansion
towers owned by the secondary partition, use the “Expansion Tower and SPCN
Controlled Expansion Unit Power Procedure” on page 926 before powering on the
secondary partition.
1. Go to the console of the Primary partition.
2. From the Use Dedicated Service Tools (DST) screen select the Work with system
partitions option.
3. At the Work with system partitions screen:
a. Select Work with Partition Status .
b. Select the Power On option next to the logical partition that you want to IPL
and press enter.
Powering Off the System
Attention: Power off and power on of a system with multiple partitions are
different than a system with a single partition. Read and understand the power off
and power on procedures referenced when a procedure directs you to power on or
power off a system or partition.
If the system is operating under Dedicated Service Tools (DST), power off the
system by selecting the
Power off the system option on the Start a Service Tool
display.
If the system is operating under OS/400, enter the
PWRDWNSYS
command to
power off the system.
Note: For consoles that run Client Access, a delayed power-off operation by using
the
PWRDWNSYS command is required. You must stop all applications,
including console applications, and subsystems that are running, before the
delayed power-off operation is complete.
If you cannot use these methods, you can power off the system by using the
“Control Panel Power Button” procedure.
Control Panel Power Button
Attention:
Using the control panel Power push-button to power off the system
may cause unpredictable results in the data files, and the next IPL will take longer
to complete.
1. Open the control panel cover.
2.
The system must be in Manual mode to power off. To select Manual mode, see
iSeries Service Functions .
