The next section discusses each of these power-on modes.
Note: You must power off your managed system to switch between using the full system partition and
using either logical or affinity partitions. You must also power off the system between using logical
parititions and affinity partitions.
Partition Standby
The partition standby power-on option allows you to create and activate logical partitions. When the
partition standby power-on is completed, the operator panel on the managed system displays LPAR...,
indicating the managed system is ready for you to use the HMC to partition its resources.
Note: The full system partition is listed as Not Available because the managed system was powered on
using the partition standby option.
Full System Partition
The full system partition power-on option allows you to use all of the system’s resources under one
operating system after the system has been powered on. This is the traditional single-system method of
using your system’s resources.
The physical operator panel on your managed system displays progress codes when you boot the system
in this mode.
If you select the full system partition option, you can then select one of the following profiles:
Power On Normal
This profile boots an operating system from the designated boot device.
Power On SMS
This profile boots to the System Management Services (SMS) menus. The SMS menus include:
v Select Language
v
Change Password Options not Available in LPAR Mode
v
View Error Log
v
Setup Remote IPL (Initial Program Load)
v
Change SCSI Settings
v Select Console not Available in LPAR Mode
v
Select Boot Options
Power On Diagnostic Stored Boot List
This profile causes the system to perform a service mode boot using the service mode boot list
saved on the managed system. If the system boots AIX from the disk drive and AIX diagnostics
are loaded on the disk drive, AIX boots to the diagnostics menu.
Using this profile to boot the system is the preferred way to run online diagnostics.
Power On Diagnostic Default Boot List
This profile is similar to Power On Diagnostic Stored Boot List Profile, except the system boots
using the default boot list that is stored in the system firmware.
Power On Open Firmware OK Prompt
This profile is used only by service representatives to obtain additional debug information. When
this selection is enabled, the system boots to the open firmware prompt.
For more information about these power-on options, see the service documentation for your managed
system.
