HPUX 10.20 ----> 11.22 upgrade

[Jeremy Loukinas]

I am getting ready to perform an OS upgrade on a 10.20 server to 11.22. I have read numerous posts about how this is not such a good idea. So this causes me to consider just doing a fresh install. The only problem with that is I have well over 200 filesystems both ufs and vxfs on multiple different volume groups. I am concerned about those volume groups during the new installation. I understand that I can run a vgcfgbackup and get my configuration info but has anyone else done this and been successful?

Thanks
Jeremy

Yeah....we've done it here. With proper planning and such, this was exactly the "no big deal" that it was made out to be. Just export your volume groups as you mention, then reimport them on t'other side of the upgrade. We've even moved volume groups (using the SAN) between systems and versions of the O/S.

errrm I presume you mean you are upgrading from HP-UX10.20 to 11.11?

HP-UX11.22 is the IPF version of HP-UX, and runs on intel itanium processors only.

Anything that is currently running 10.20 must be a PA-RISC processor system (thats all there was when 10.20 was around).

Before doing anything else make sure you have CDs for installing/upgrading to 11.11 or your not goinng anywhere.

Now was that on an upgrade or a fresh installation?

Your right 11.11. Sorry about that.

This is a very straightforward migration. You are really only cold installing vg00 and then everything else is a vgimport.

Make sure that you have files and hardcopies of /etc/fstab, bdf output, strings /etc/lvmtab, vgdisplay -v, and vgexport -p -m mapfiles.

After you do the OS install, install latest HWEnable patches, install MirrorUX and OnlineJFS, and then install latest GOLDQPK patchset and you will be all set to vgimport.

If this were me, I would install 11.11 on another set of disks so that you then have a way back (and your can even vgimport/mount the old vg00 disks in case you missed something).
