Logical Partitions - System Profile
The following scenario explains how system profiles are used on systems that are managed using a Hardware Management Console (HMC).
Server firmware is the code that resides in system flash memory. Server firmware includes a number of subcomponents, one of them being the logical partition firmware.
The HMC is a system that controls managed systems, including server hardware, logical partitions, and Capacity on Demand.
A system profile is an ordered list of partition profiles. When you activate a system profile, the managed system attempts to activate the partition profiles in order. In this example, you have activated a system profile with three logical partitions.
You can change the configuration of your managed system by activating another system profile. Before activating another system profile, you must shut down the logical partitions. In this example, you power down partitions 1, 2, and 3.
After you power down the partitions on the managed system, you can activate another system profile. In this example, you activate a system profile with two logical partitions.
