Chapter 1. Introduction to LPAR on IBM System i5 5
This allows one system to adopt multiple personalities. In this type of scenario we are
assuming the partitions will be reloaded at the disaster recovery site with no data on the disk.
1.2 Software requirements
The IBM ^ System i5 systems require one of the following levels of operating system:
򐂰 OS/400 version 5 release 3 or later.
򐂰 AIX 5L™ version 5.2 with native IO support. AIX 5L version 5.3 will support hosted IO as
well as native IO support.
򐂰 Linux version 2.6 for PowerPC®, which relates to Red Hat Enterprise Linux AS for
POWER™ Version 3 and SUSE Linux Enterprise Server 9 for POWER. For more

1.2.1 What’s new for licensing
These are some new licensing features:
򐂰 The number of OS licenses is now based on what the server is
configured to use.
Previously, the server price included the licenses for all startup processors.
򐂰 An OS/400 license key is now shipped to ensure compliance for the number of processors
purchased versus used. It applies to licensed program 5722-SS1 feature 5051 of OS/400
V5R3.
򐂰 The LPAR Validation Tool (LVT) is adding a new function to report licensing requirements.
1.2.2 Licensing requirements
These are the basic rules for Operating System licenses on ^ System i5 machines:
򐂰 For dedicated partitions, the number of licenses equals the
desired number of processors
configured.
򐂰 For capped partitions, the number of licenses equals the total of the
desired number of
processing units configured rounded up to the next whole number.
򐂰 For uncapped partitions, the number of licenses equals the
maximum number of virtual
processors configured, up to the limit of the number of
physical processors in the shared
pool.
򐂰 For On/Off Capacity on Demand (CoD), there are no additional licensing charges
associated with a temporary processor activation.
