update-ux

Hi Gurus,

I am planning to upgrade my hpux 11.00(PA-RISC) to 11.23.
What I want to know is, which one will be better; fresh installation or using update-ux?

What will be the advantages of update-ux?

Thanks in advance..

Hi:

If you are moving from 11.0 to 11.23 you need to cold-install. You cannot jump directly from 11.0 to 11.23.

In general, a cold-installation is the cleanest, most guaranteed path forward. You have the ability to size your vg00 filesystems to best fit your needs without undue effort.

Regards!

Yes, is best to forget about update-ux, when updating from 11.00 to anything, best a cold install.

I'm in the final stages of updating 6 servers from 11.11 to 11.31. They are all vPars and had to have that software upgraded also to make it a little more interesting. I have a test server to play with and tried update-ux on it. Interesting exercise but NOT something I would use in reality. I had multiple issues in each update-ux step (11.11 to 11.23) and (11.23 to 11.31) that I had to investigate/fix which extended the time. It would have been a long/interesting weekend running the pair of update-ux's on the servers. It was much quicker/cleaner to build a 11.31 server from scratch, and then customize it for each servers specifics.

Hi (again):

OK, so it's 11.11 to 11.23. I would *still* do a cold-install. It's so much cleaner and more guaranteed to work the first time!

All you need do is to create mapfiles for your non-vg00 volume groups with the '-s' option to collect the VGID in the mapfiles; and once your vg00 is ready, 'vgimport' the volume groups.

S. Rider's expriences are the same as what most encounter.

update-ux might just work, but more often something fails that either consumes all your time to resolve or your system is left unusable.

What ever way you choose ( cold install ;) make sure you have at least two Ignite images that have been tested.

Best of luck.
