A partition is a portion of a computer system that is supported by its own hardware resources (such as processors, memory, and input/output) and runs its own operating environment. You can commission multiple partitions on a Partitionable Enterprise Partition Platform (PEPP).
Partition Image Lifecycle
Commissioning the partition image
Discovering the available resources (blueprints and gold images)
Mapping the partition image to appropriate resources and attributes (blueprint, gold image, LUN size, and hyper threading)
Note: Logical unit numbers (LUNs) identify a segment of storage on the enterprise partition platform that span across the internal hard drives.
Performing starting or stopping operations (soft shutdown, force dump, force halt, soft restart, and hard restart)
Enabling and disabling the partition image
Adding multiple images to the partition chassis
Decommissioning the partition image
