Upgrading to Integrity VM Version 4.0 from 3.X

Pre-Upgrade Preparation Steps

Preparing the Integrity server from a Hardware / Firmware Perspective

Before beginning the migration, read the documents HP-UX 11i v3 Read Before Installing or

Updating, and HP-UX 11i v3 Installation and Update Guide (September 2008 (Update 3) versions or

later) to understand the base requirements of HP-UX itself. Also check HP Integrity Virtual Machines

Version 4.0 Installation, Configuration, and Administration (available at http://docs.hp.com)

Appendix A to determine whether the guest operating systems currently in use are supported by 4.0.

Finally, download the HP-UX 11i v2 and 11i v3 Mass Storage Check Utility (msv2v3check) from

http://software.hp.com. While the aforementioned documents specify the hardware and firmware

requirements for 11i v3, the tool implements many of the necessary checks.

It is possible that an upgrade will be feasible, but that extra downtime might be required for the host

in order to update the system and/or IO firmware. Also, it is possible that older IO cards might need

to be replaced.

Performing Basic Preparations

Once the hardware and firmware pass the checks and you have decided to go ahead with the

upgrade, you need to do the following:

– Download and run hpvmupgrade on the VM host to verify that all of the guests are ready for

the upgrade. Be sure to check the ITRC for any hpvmupgrade patches before running the utility.

This tool is part of the VMGuestLib bundle for Integrity VM 3.X and is available both at

http://software.hp.com and on the HP-UX 11i v2 AR media, September 2008 (Update 3

Release) and later. The command:

hpvmupgrade –e

Saves all errors and warnings to:

/var/opt/hpvm/common/hpvmupgrade.{date&time}

A sample of the hpvmupgrade output is in Figure 2, below.

– Back up the VM host and all guests. It is particularly important to back up /var/opt/hpvm if

you plan to do a cold migration.

– Gracefully shut down all guests.
