NOTE: Integrity VM Version 4.2 and later support both 4KB (default) and 64KB settings for

the base_pagesize tunable. In previous versions, installation of Integrity VM set the base_pagesize

tunable to 64KB, because of the significant improvements in memory efficiency that resulted.

HP still recommends setting the base_pagesize tunable to 64K for this reason. However, there

are several defects that can potentially hamper software installation and operation when HP-UX

is configured with 64K base_pagesize. For more details, see the white paper on this topic, Tunable

2.3 Upgrading the VM Host from Previous Versions of Integrity VM V3.X

to Integrity VM V4.3

Integrity VM Version 4.3 VM Host requires the HP-UX 11i v3 operating system. Only HP-UX

11i v2 servers running Integrity VM Version 3.0 or Version 3.5 can be upgraded to the HP-UX

11i v3 Integrity VM Version 4.3 release. This section describes the process to follow when

upgrading an HP-UX 11i v2 based Integrity VM server to an HP-UX 11i v3 based Integrity VM

server. If you are upgraded the VM Host from Integrity VM V4.0 or later to Integrity VM V4.3,

see Section 2.4.

HP-UX 11i v3 supports many features that are backward compatible with 11i v2, allowing 11i

v2 applications to run without modifications. The primary goal of this section is to provide

direction to the administrator performing the upgrade of the VM Host to make sure that all

configured virtual machines (guests) boot and run after completing the upgrade to 11i v3.

Figure 2-1 provides a flowchart of the upgrade procedure from 11i v2 to 11i v3.
