Upgrading from HP-UX 10.20 to 11.x

Shaun Aldrich — Wed, 08 Nov 2000 20:04:52 GMT

Hello Everyone,

I know there have been many threads on this in the past as I have read many of them but I was wondering if anyone who has done a successful upgrade has any kind of checklist put together on the steps taken.

I am looking to see if there is any step by step procedure for completing successfully such a task?

There are many steps which I imagine will be involved in this activity such as:-

1) Analysis of each of the Systems as well as Environment

2) Impact???

3) Method??? I have heard of two major ways of accomplishing this task. The first is to upgrade the current OS ( not sure what the steps are or what is involved but I have heard of individuals in the HP Forums having problems with this method ). The second is to do a Cold Install of HP-UX 11.x ( This I imagine would be a lot of work as well as you would have to re-install the apps and recover all the data ). It seems from what I've read in the Forum that the second method of a Cold install is the preferred method. What are your thoughts on this? Which method have you completed successfully in the past.

4) Planning???

5) Oracle & other major Applications on the box ( Omniback, Autosys, MirrorDisk.....)

6) Other Utilities

7) Patches for HP-UX 11???

8) Recovery???

9) Firmware Upgrade???

10) EMC issues???

Any help with some sort of logical procedure would be greatly appreciated...

Thanks

S Aldrich

Shaun,
I haven't met an HP-UX administrator yet that prefers the upgrade approach over the cold install. The way I do this is a follows:
1. Identify all root filesysems and files (like /etc/services, ntp.cont, etc.. that will need to be restored.
2. backup everything on the system
3. vgexport all non-root volume groups
4. Cold install the OS, and install any patches.
5. Configure the new OS - IP addresses, restore saved files like /etc/services, NTP,
resolv.conf, etc.
6. vgimport all non-root volume groups

Done.
The critical work here is identifying the root files and filesystems that need to be preserved from the root volume group.

Shaun,
I forgot something,
You will have to get new codewords for applications like mirror-ux, gpm, OJFS etc. and re-install these after the new OS is configured. Don't forget to save files in /sbin/init.d, and /etc/rc.config.d. I don't think I have left anything else out.

Thanks for the reply.

Once you do the cold install of HP-UX 11.x could you not restore almost all of the main components of the root filesysems and files (like /etc/services, /etc/hosts, /etc/fstab, /etc/lvmtab....etc). That way applications such as Omniback, Autosys, Oracle and so on will not fail...

Please let me know what you think...

Thanks,

Also remember to have any third party drivers and software for Fibre channel adapters and the like (eg. EMC = navisphere etc.) ready and handy. Your HPUX applications CDs are also essential.

Good luck.

Yes Shaun, you can restore most of the files that you have customised /etc/hosts /etc/services but not the volume group related files and not the device files because they may be enumerated different from 10.20.

You cannot "restore" Omniback/oracle or any other application directly as is - you would have to install them with (but after installation you can restore any configurations that you may have saved.)

The filesystems are essentially the same but some files are placed differently eg. /etc/ftpusers (HPUX 10.20) /etc/ftpd/ftpusers (HPUX 11.0)

Shaun:

Two general comments:

1. As part of a good insurance policy, I would make an Ignite make_recovery tape of your system before you start your 10-to-11 transition.

2. Make sure you have the required minimum PDC revision and minimum firmware revision installed for your processor.

If you have the Diagnostic Support Tools installed, you can obtain the values by doing the following:

# ioscan -fn -C processor
# echo "sel path 32;info;wait;infolog"|cstm > /tmp/infolog

The above assumes that the hardware path of the processor in question was "32" as returned by ioscan.

Match the PDC and firmware values to the table found in chapter-2 of "Installing HP-UX 11.0 and Updating HP-UX 10.x to 11.0":

Thanks James / Kofi,

Just a couple more questions after receiving your responses.

I know you mentioned that I would be able to restore most of the files that you have customized such as /etc/hosts /etc/services but not the volume group related files and not the device files because they may be enumerated different from 10.20.

What exactly do you mean by not the volume group related files and not the device files? Does that mean I would be able to restore /etc/fstab, /etc/mnttab...etc? Any further examples would be great....

You also mentioned that I cannot restore Omniback, Oracle and other applications. Does this mean that I would have to re-install them completely and then just restore all of the configuration data for them?

Also I have one last questions. You mentioned about checking both the PDC and firmware values and matching them with the table in the upgrade manual. After this is checked if I find that these need to be upgraded where can I find the latest upgrades? Do these then need to be upgraded before I begin the upgrade procedure to 11.x?

Thanks for all your help and responses....

Definitely seems like there will be a lot of planning before this is started...

Shaun:

With regard to the PDC, if you need updates, place a call to HP Support and request a local engineer to refresh your firmware. This will mean downtime, for you, but it doesn't take but a few minutes. This is something I like to have done about once a year to keep current. Good Luck.

Ok, the files in /dev are created based on the OS drivers for particular devices - and since the drivers under 10.20 are not exactly the same as those under 11.0 /dev files created under 11.0 will not be the same as those from 10.20.

the lvm information would have to be rebuilt because upon installation, you would not have any volume groups created and will have to create them before you start carving logical volumes/filesystems out of it.

Yes, you will have to re-install Omniback, Oracle and other applications and load up the configuration files (which usually stay the same). The proper way to put software on a system is to install - this is because files may not all be stored in the same directory structure, and there may be internal databases (eg. software like omniback need to be installed with swinstall)
...and in some cases, the software for 11.0 is completely different from 10.20.

Yes there is a lot of planning involved but once you have it all nailed down, you will be glad you planned ahead!

I have just been through a couple of upgrades, and it was a lot of fun because I had planned ahead.

Good luck.

Shaun Aldrich — Thu, 09 Nov 2000 16:25:47 GMT

Thanks for the reply Kofi,

I guess having to rebuilt the whole lvm structure is a good thing in a way especially if you want all of your filesystem sizes larger as well changing things like the type from hfs ( which is what was set up before I got here ) to vxfs.

Do you know anything about HP Predictive Support? We have it installed & configured right now under 10.20? Does that mean that this will have to be obtained for 11.x, installed & re-configured? Can you just back it up under 10.20 and restore it once 11.x is installed? If not, does anyone know where I obtain it from?

Thanks for everyone's help...

Predictive comes with the Support Plus CD. And yes the version for 11.0 is different from the version for 10.20. You should be able to get HP to send you the media (if you do not already have it) there is a little booklet that comes with it that explains what each bundle contains and how to install it.

James R. Ferguson — Thu, 09 Nov 2000 16:34:18 GMT

Shaun:

Predictive Support, Support Tools (stm), etc. can be found on the current Support Plus CD. You will need to swinstall using
/cdrom/DIAGNOSTICS/B.11.00

Very Impt:Make the make_recovery tape on 10.X before upgrading to 11.XX. If upgarde fails you can go back to old OS with out any problem.
Secondly install all the latest Patches for the existing 10.X. Why i am telling this is, because my upgrade from 10.20 to 11.00 failed because of Patches. Upgarde failed while Kernel rebuild and system crashed. I had to go back to 10.20 and install all patches and start upgrade again.

Hi Shaun,

this is my way to upgrade :

1. find out all your applications (swlist, ...) uns configuration files
2. reorganize your LVM and filesystem layout, move all your non HP-UX applications and data (if possible) outside vg00
3. check your hardware and firmware (CPU,PDC,Eisa cards in D-class,...)
4. check your applications for HP-UX 11.x (32/64bit?)
5. check your CDs/depot (install CD, application CDs, newest patchbundle, Diagnostics, non HP-UX applications)
6. write down some configuration data (network, timeserver,...)
7. save configuration files (fstab,passwd,group,network,rc.config.d,rc?.d/*,/etc/*.conf,crontab,...)
and make some listings (ioscan -fn, vgdisplay -v, printer, ...), save also your mountpoint and symbolic link infos for non vg00 filesystems and dirs
create mapfiles of VGs
8. make_recovery -A
9. save this files and output seperatly to DDS or over LAN
10. save remaining non HP-UX data and /home
11. full backup
12. save your HP-UX 10.x HD (or mirror disk)

... and start

1. shutdown
2. replace hardware (if nessesary)
3. firmware upgrade (if nessesary)
4. boot with install CD (vg00 layout, network, ...)
5. install application, patchbundle, diagnostics, ...
6. kernelparameter, new kernel
7. modify passwd and group
8. create your VG's
9. import your VG's (with mapfile)
10. create your mountpoints
11. modify fstab
12. mountall
13. create symbolic links
14. configure your system with saved files
15. restore /home and remaining vg00 data

... and i hope you don't need the backups and saved disk
