How to upgrade or install HP-UX from 10.20 to 11.20

Currently, I have non-use 10.20 machine (K460) and I want to make it to 11 version. May I upgrade it or remove all the OS and install a fresh HP-UX 11 ? Where could I find the procedures to upgrade or install the OS steps.

All documentation you could need is at http://www.docs.hp.com/

In case you mean 11.0, try http://www.docs.hp.com/hpux/os/11.0/index.html

Hi

I think better to make a fresh install. I test
twice (install and upgrade) and install seems
better.
In your case, a K460 can support 64 bits system
(I saw that in /etc/.supported_bits on one of
my systems), so you will change of release and
architecture, it's really better to make a
fresh install.
You can find informations on http://docs.hp.com

I would also vote to do a fresh install instead of an update. Thing get really messy when you try to do an update on the system. You might get lucky and everything would go smoothly, but my experience has been that you're likely to run into some problems along the way and will wind up doing a fresh install anyway.

Btw, the latest version of 11.x for PA-Risc systems is 11.11...I don't believe 11.20 is out yet.

Re: How to upgrade or install HP-UX from 10.20 to 11.20

Hi Idris:

There are a hugh number of threads in this Forum on this subject. The principal echo is that cold installation is virtually guarenteed to be successful whereas an upgrade often leads to problems during and after.

Consider that a cold installation gives you the opportunity to resize your vg00 filesystems.

Consider that with a cold installation you merely need to cold install to your boot disk and 'vgimport' your non-vg00 volume groups to regain visibility to your data.

Consider that with a cold installation you start with your Core OS, add your Application CDROM products, diagnostic software (STM, Predictive Support, and EMS) and then apply a current Support Plus patch bundle (QPK). You end up with an up-to-date system in a short time.

Start your installation by making an Ignite recovery tape of your existing vg00. In this way, should anything fail, you can rapidly restore your system.

Capture your key configuration files before you start. I like to 'diff' these files to those provided by a new release and "marry' my local needs to any enhanced features. Otherwise, many of them can be loaded as is.

Here's the basic list I tranfer to safe-keeping for reference, reuse, and comparing against new configurations (via 'diff') during a cold installation process:

# /.forward
# /.profile
# /etc/profile
# /etc/group
# /etc/hosts
# /etc/inetd.conf
# /etc/inittab
# /etc/nsswitch
# /etc/ntp.conf
# /etc/passwd
# /etc/rc.config.d/netconf
# /etc/rc.config.d/netdaemons
# /etc/rc.config.d/nfsconf
# /etc/resolv.conf
# /etc/sendmail.cf
# /etc/services
# /etc/shells
# /etc/shutdown.allow
# /var/adm/cron/*.allow
# /var/adm/fbackupfiles/*
# /var/spool/cron/crontabs/*
# /sbin/init.d/

Don't forget to add your volume group 'vgexport' mapfiles too.

Regards!

Hi Santosh:

Release 11.20 is for the Itanium processor. 11.20 is also refered to as "11i version 1.5" whereas 11.11 is "11i version 1.0.

Idris,

The other guys have taken their time
to answer your question. Please take
the time to assign points as a reward
for giving up their time for you.
Your contibution for assigning points
to your many questions that have been
answered correctly is not good.
38 times assignment of points to 238 responses is not a good statistic.

Re: How to upgrade or install HP-UX from 10.20 to 11.20

As you can see the overwhelming majority has stated that a fresh install of ANY OS is far better and more assuring that you will have a more stable OS. A fresh install, wether it's an MS product, HPux, AIX, solaris, whatever is the safest bet. From experience, I can tell you that I have never had any success upgrading ANY OS.

The problem, even if you did a fresh install of the latest 10.20 release and then attempted to upgrade to 11.20 or any 11.x release is that your chances of success rapidly approach ZERO (/dev/null).

Also, over the years, I have found so much crap in a prior OS, that I didn't remember putting there, so a fresh install assured me that that garbage would get blown away.

Also, if you want a secure machine, look at this document:
