HP11i v2 update

[navin]

Hello All,
I have to apprecitae forum members since i got most of the answers regarding hpux update.
But is there any success story of using update-ux for HPUX upgrade. Becasue most of them were suggested to not use the update-ux instead to use the cold install.
as always thanks in advance,

Hi,

I performed several updates with succes. I always preperred the update on a standby server to check what the problems might be.

Thank you ,
-Is it possible to outline a 5 to 6 line procedure that helps hpux upgrade process.
I really appreciate your help.

-What happens if the /opt has some application stuffs during the upgrade , will it be preserved.

-the server has multiple disks .The main applications are resides on the different volume groups ...than root volume group vg00
do i need to vgimport other volume groups during when i run update-ux.please help.
Thanks

Sorry , there is a correction in my question.

-do i need to export the other volume groups during the upgrade process , and then import it after the upgrade.
thanks

Shalom,

You do not need to export volume groups during the upgrade in general.

Which way to go depends on the software in general. Oracle for example may need to do data conversion, though I doubt it would do that during upgrade-ux. I don't even think Oracle officially supports upgrade-ux though it works.

Upgrade-UX has not been reliable for some time. Bill Hassell told me a story at an airport about one time a long time ago it working right, but I'm not impressed with the results from my own tests.

The upgrade process was fairly stable in HP-UX versions 7, 8 and 9 but each new version became less reliable, primarily due to the larger number of changes in the kernel and subsystems with each new release, and the inability of the upgrade tools to handle every possible condition. Start with 10.xx, and upgrade was almost always a failure (ie, 9.xx to 10.xx) as are all 10.xx to 11.xx upgrades. And despite the seemingly minor difference between 11i ver 1 and ver 2, many upgrades will fail or require extensive fixups that are not documented or readily apparent. And if you look at the /var/adm/sw directory structure, most of the patch history is invalid for the new OS.

Most of the requests for upgrades are based on preserving the current applications without having to upgrade them at the same time. But the reality is that the huge improvements in each new version of HP-UX often mean that the application is no longer completely compatible and has to be upgraded too. So after the upgrade is completed, the applications no longer work and must also be upgraded.

When you consider the issues of old patches and old applications, changes in the names of drivers (ie, the btlan series), even driver changes that require I/O or CPU firmware to be upgraded, the success rate is extremely low and total labor effort is always much, much larger than for a complete reinstall.

So the only success story I have was for a trivial system (one LAN card, internal SCSI disk and tape) going from 11.00 to 11.11 with *NO* application programs -- not much of an endorsement for the upgrade process. But it definitely pormotes the purchase of a test or sandbox system to perform the cold install and test everything.

Thanks very much you all for taking time to reply and helpdful ideas.
