Migrating from HP-UX 11i v1 Virtual Partitions to a Mixed HP-UX Version Environment

12
Preparing Virtual Partitions being Left on HP-UX 11i v1 or 11i v2
At this point, all of the HP-UX 11i v1 virtual partitions should be running vPars A.03.05 or later. All
of the HP-UX 11i v2 virtual partitions should be running vPars A.04.05 or later. All that is required of
these virtual partitions is that they be halted gracefully once the virtual partitions being upgraded have
been halted (and it is convenient).
Completing the Update to HP-UX 11i v1/v2/v3
Reboot the nPartition taking care to boot to an HP-UX 11i v3 monitor.
Note:
The HP-UX 11i v1 and 11i v2 monitors cannot boot the HP-UX 11i v3
virtual partitions.
Once the monitor has booted, you may vparload all of the virtual partitions.
• The HP-UX 11i v1 and 11i v2 virtual partitions will come up rapidly.
• The HP-UX 11i v3 virtual partitions may take a couple of hours to complete their update by
configuring all of their software.
This is normal, and the other virtual partitions may be used for production work while you are
waiting.
Final Preparations for Production Mode
At this point, all of the virtual partitions are ready for applications to updated, data disks to be
remounted, and standard pre-production verification tests to be run.
HP recommends that once such steps are taken, and before allowing users on the systems, that new
recovery images be made and that any data center automation tools such as gWLM be restarted.
Conclusion
It is now possible to upgrade installed virtual partitions piecemeal to HP-UX 11i v3, while minimizing
the impact to production workload virtual partitions. With careful planning and attention to the newer
operating environment's prerequisites, users may now proceed with a "rolling upgrade" of their
virtual partitions and satisfy conflicting business/application requirements on a single piece of
hardware.
