HP-UX vPars and Integrity VM V6.3 Administrator Guide

4 Upgrading the VSP from earlier versions of Integrity VM
This chapter describes how to upgrade the VSP from an older version. You must know the following
before upgrading to a newer version:
• vPars and Integrity VM V6 supports guests running HP-UX 11i v3 and HP-UX 11i v2 (starting
from V6.1.5). It does not support OpenVMS guests.
• Integrity VM V4.3 and earlier versions used VIO interfaces and Legacy DSF's for mass storage.
These are not supported on vPars and Integrity VM V6 and later releases.
◦ You can use the hpvmmodify command to convert VIO interfaces to AVIO.
◦ You can use the hpvmdevtranslate command to convert Legacy DSF files to Agile
DSF.
NOTE: If you are upgrading from earlier versions of vPars (A5.x), see the detailed upgrade
procedure documented in Realize new workload migration and consolidation possibilities white
paper at http://www.hp.com/go/hpux-hpvm-docs/.
4.1 Upgrading VSP from Integrity VM V3.x to vPars and Integrity VM V6.3
The vPars and Integrity VM software requires the VSP to be running 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 vPars and Integrity VM Version 6.3 release. If you are upgrading the VSP from
Integrity VM V4.0 or later to vPars and Integrity VM V6.3, see Section 4.2 (page 50).
HP-UX 11i v3 supports many features that are backward compatible with 11i v2, allowing 11i v2
applications to run without modifications. The primary aim of this section is to provide direction to
the administrator performing the upgrade of the VSP to ensure that all configured VMs (guests)
boot and run after completing the upgrade to 11i v3.
Figure 4 (page 44) shows a flowchart of the upgrade procedure from 11i v2 to 11i v3.
