urgent: how to upgrade?

[Ivan Efimenko]

Hi.
We have middle-end class server and would like to upgrade it from HP-UX 11.00 to HP-UX 11i (11.11)
We have 2 HDD in server.

First HDD used for system and second one used for swap.

I want to remove swap from the second HDD, then mirror system hdd to free hdd, break the mirror.
After, boot from one of HDDs and try to upgrade the system using Ignite/UX.

Can you describe me the steps to do these tasks, because its very nervous for me to make errors somewhere and crash the system.

And the last question. If I'll try to upgrade system from 32bit UX to 64bit, do I need to reinstall all applications (which were worked on 32 bit system)? I think, Yes.

Thank you in advance.

I would first make a recovery backup using make_recovery from the Ignite/UX tools.

Then I suggest you read the manuals available at http://www.docs.hp.com/hpux/os/11i/index.html

You can upgrade all applications,see manual of make_recovery in http://www.docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B2355-90704/B2355-90704_top.html&con=/hpux/onlinedocs/B2355-90704/00/00/55-con.html&toc=/hpux/onlinedocs/B2355-90704/00/00/55-toc.html&searchterms=make_recovery&queryid=20010521-080325

Hi Ivan:

1. To eliminate your swapspace from the second disk (volume group, I presume), edit /etc/fstab and remove the entry for the swap area. Then reboot your system.

2. I would make a 'make_recovery_tape' before attemting any upgrade or cold install. This is your easist "fall-back" in the event of failure.

3. Mirroring your vg00 to your second (free) disk, and spliting the mirror might is superflous if you are going to do a cold-install onto the second disk.

4. The collective experience of this Forum has always been that cold-installs are far more likely to succeed where updates ("in-place") are far more problematic.

Hi Ivan.
James is totally correct. I would do a cold install too.
James, I think you changed the command :)
It's "make_tape_recovery".
good luck.

Hi again:

'make_tape_recovery' is the *replacement* for 'make_recovery' in Ignite 3.2 and later. The functionity is much improved, in my opinion, over 'make_recovery'. Volume group vg00 can be archived with 'make_tape_recovery' with the following simple command:

# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

Don't confuse the '-i' option of the old 'make_recovery' with the '-i' option of its replacement, 'make_tape_recovery'. The '-I' option of make_tape_recovery is the *same* as the '-i' option of make_recovery. '-I' means cause the Ignite process to be interactive when booting from tape.

Thanks! Yes, I'm a bit dyslexic this morning. 'make_tape_recovery' is what I meant. ;-) ...with warm regards...

Hi Ivan,
OK.
1. First of all try to have one full backup of vg00 using make_recovery.
2. Second do a full data backup.
3. By doing the mirroring, it's a manner to have a backup of both vg00 and data. it's a good thing to restore from crash.
4. upgrading the hp-ux.
5. You don't need to reinstall applications( you had done an upgrade and not an installation ). The file systems are still valid and containing binaries, libs, ...
