Logical Partitions - Partition Profile
The following scenario explains how partition 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.
In this example, there are three logical partitions. Each logical partition has at least one partition profile. A partition profile is a record on the HMC that specifies a possible configuration for the logical partition. A logical partition can have more than one partition profile.
To activate a logical partition on the HMC, you must activate one of the partition profiles for that logical partition. When you activate a partition profile, the HMC assigns resources to the logical partition based upon the partition profile settings.
In this example, you activate partition profile D for partition 1.
In this example, you activate partition profile G for partition 2.
In this example, you activate partition profile J for partition 3.
When you activate a different partition profile, you change the hardware resources assigned to the logical partition. You must shut down a partition before you activate another partition profile for the partition. In this example, you power down partition 1 and 3.
After you power down partitions 1 and 3, you can activate other partition profiles for those partitions. In this example, you activate partition profile E for partition 1.
In this example, you activate partition profile H for partition 3.
