System Profile
The system profile option powers on the system according to a predefined set of profiles.
Note: The profiles are activated in the order in which they are shown in the system profile.
Power-on Autostart
This option powers on the managed system to partition standby mode and then activates all partitions that
have been powered on by the HMC at least once. For example, if you create a partition with four
processors, and then you use dynamic logical partitioning (DLPAR) to remove one processor, and then
shut down the system, the Power-on Autostart option activates this partition with three processors. The
system activates the partition with three processors because the three-processor configuration was the last
configuration used, and the HMC ignores whatever you have previously specified in the partition’s profile.
Using this option, the partitions boot using AIX, even if some of the partitions had previously been defined
to use another power-on option.
Media Subsystem Operator Panel Power-On
Perform the following steps to power-on the processor subsystem and attached I/O subsystems using the
power button on the media subsystem operator panel.
1. Open the rack door. Look for
OK
in the primary operator panel display, which indicates that the system
is in standby mode.
Note: If the power has recently been connected to the system, you might need to allow approximately
five minutes after the OK prompt displays before pressing the power-on button on the media
subsystem, or using the service processor, to turn the system power on.
2. Press the power-on button on the media subsystem operator panel.
The power LED on the media subsystem operator panel starts blinking at a fast rate. 9xxx checkpoints
appear in the operator panel display.
When the power-on sequence is complete, the following events have occurred:
v
The power LED on the media subsystem operator panel stops blinking and stays on.
v
The power LEDs on the I/O subsystem come on and stay on.
