RE: v4r5 lpar

Deb,

IBM has not updated their online documentation for LPAR/V5R2 yet, but I
doubt very much that you would be able to run V5R2 on a secondary
partition with V4R5 in the primary.  The web site on release support
(see below) clearly states that with V4R5, a two-step jump in the
secondary (P+2) is not supported.  The only exception to this policy is
running V5R1 in a secondary with V4R4 in the primary; this is clearly
noted as an exception for these releases only.

Regards,
Andy Nolen-Parkhouse

LPAR release support site:

jxreleasesupport.htm

Some text from that site:
Systems with logical partitions have the capability to support more than
one version of OS/400. The logical partition strategy is to support up
to three different releases on the same system. Using the primary
partition as the reference release (denoted as P), the strategy is to
support secondary partitions of one previous release of OS/400 (P - 1),
the same release as the primary (P), and a future release (P + 1).

For example, if your primary partition is running V4R5, you can install
V5R1 on a secondary partition. However, since your primary partition is
running V4R5, you will not benefit from the V5R1 enhancements in the
secondary partition running V5R1. You are limited to the release
function of the primary partition. Likewise, if you install V5R1 on the
primary partition, you can run V4R5 on one secondary partition while the
other secondary partitions run V5R1. In this example, since the primary
partition is running V5R1 all secondary partitions running V5R1 will
have the increased functionality of the release. However, the secondary
partition running V4R5 is limited to the release function established
for V4R5.
