1. Abstract This white paper is intended for individuals who are interested in consolidating virtual partitions (vPars) running different HP-UX versions onto a single hard partition. This document describes the supported configurations and guidelines for operating mixed HP-UX versions environment and describes some tools available to aid in configuring and managing the virtual partitions.

vPars A.05.03 was released with HP-UX 11i v3 (11.31) and is designed to support a mixed HP-UX 11i v1/v2/v3 vPars environment. This mixed environment allows the user to boot a vPars A.05.03 monitor that supports virtual partitions running HP-UX 11iv1, HP-UX 11i v2, and HP-UX 11i v3 in the same hard partition as shown below in Figure 1. Note that the virtual partitions running HP-UX 11i v2 must have vPars A.04.02 or later installed, and that virtual partitions running HP-UX 11i v1 must have vPars A.03.

This mixed environment allows the user to boot a vPars A.04.05 monitor that supports virtual partitions running both HP-UX 11i v1 and HP-UX 11i v2 in the same hard partition as shown below in Figure 3.

4. Configurations 4.1 Supported Configurations The following vPars versions are supported in various mixed HP-UX combinations in vPars environment. Mixed HP-UX 11i v1/v2/v3 vPars For Mixed HP-UX 11i v1/v2/v3 vPars environment within the same hard partition, note that the vPars monitor that must be used is that bundled with A.05.03 or later.

HP-UX vPars environments. Also, please refer to the HP-UX Virtual Partitions Ordering and Configuration Guide for OE and software requirements for each vPars versions. All HP-UX features specific to that HP-UX version release will be supported on the vPar running that version of HPUX, unless otherwise noted".

the 11i v3 virtual partitions even in a mixed HP-UX 11i v1/v2/v3 vPars environment. Offline memory migration will continue to work on all the virtual partitions. • On HP Integrity systems that support Hyper-Threading, if the system has Hyper-Threading turned on using the setboot command or other means, the HP-UX 11i v2 virtual partitions will not boot. This limitation is present because HP-UX 11i v2 does not support Hyper-Threading on settings. 5.

6. Pitfalls: What They Are and How to Avoid Them Along with the benefits of operating virtual partitions in a mixed HP-UX 11i v1/v2/v3 vPars environment, there are certain scenarios that could result in confusion. These are listed here to help you configure your environment in such a way to obtain the full benefits of operating in a mixed HPUX 11i v1/v2/v3 vPars environment. • Configuration in which there are no virtual partitions running vPars A.05.

o Detect an HP-UX 11i v3 boot disk using the EFI paths displayed at the EFI shell. The hardware path to EFI path mapping can be obtained by using the –e option to ioscan(1M) or by using vparefiutil(1M) on a virtual partition in that hard partition (if it is up) to see the EFI path mapping to an HP-UX 11i v3 boot disk.
