Use this information to plan security for logical partitions (LPARs) on your servers.
Logical partitions allow you to distribute resources within a single server to make it function as if it were two or more independent servers. Each logical partition operates as an independent logical server. However, each partition shares a few physical system attributes such as the system serial number, system model, and processor feature code.
The security-related tasks that you perform on a partitioned system are the same as on a system without logical partitions. However, when you create logical partitions, you work with more than one independent system. Therefore you will have to perform the same tasks on each logical partition instead of just once on a system without logical partitions.
