The Hardware System Console (HMC) user interface provides the functions you need to create and maintain a multiple-partitioned environment. Read the following to learn more about creating, maintaining, and deleting partitions.
The objective of logical partitioning (LPAR) is to provide users with
the ability to split a single CEC into several independent systems. Each
of these systems, called partitions, is capable of running applications
in multiple, independent environments simultaneously. Logical partitioning
makes it possible for a user to run a single application using different
sets of data on separate partitions, as if that application were running
independently on separate physical CECs. By creating partitions, for example,
a company can test its program on one partition while developing the same
program on another - at the same time, all by using the same machine. This
"same machine" partitioning method is more cost-effective, potentially
eliminating the need for a separate test machine.
