root vg

[peter van der kamp]

After upgrading from hp-ux 10.20 to
hp-ux 11.00 the root vg (vg00) does not show anymore. VGDISPLAY does not see vg00 but it does see the other volume group.
This was an upgrade and not an cold install.
In SAM it says that the disk is unused. The complete os is on that disk. What is going wrong here and how can i correct this.

You upgrade is successful, from my understanding. It's just that maybe your LVm binaries (10.20 vs 11.00) got mixed up. I've encounter this problem before and the resolution is to remove patch PHCO_19479 (LVM cumulative). For my case apparently my LVM binaries got mesed up because I have MirrorUX installed on the 10.20 system and if his happens, the patch will cause the LVM binaries not getting updated. So if this is your case.. you should ,,
1) remove PHCO_19479
2) install 11.00 MirrorUX
3) reinstall PHCO_19479

thanks for youre quick respons, i will check if that patch is installed and then remove it because we don't use mirrorux on that system.
The upgrade was succesfull. At least i think so because the rest is working correct.
One thing comes me to mind now and that is that swverify stopped with an exit error code.
I've run swverify to check out if every thing was correctly installed.
I only dont't remember the exact message.
I will check it out tommorow.

here is some additional information.
I wanted to make a recovery disk to and these errors i received.
vgdisplay: couldn't query volume group /dev/vg00. possible error in the volume group minor number; please check if its unique.
vgdisplay: cannot display volume group /dev/vg00.
lssf: must specify a special file.
save_config: error unknown disk type for , not scsi or hpfl.
save_config:error cannot determine oot disk.

i sure hope someone can help me with this problem.

Installing Mirroring on HPUX v11.00 installs a new version of the LVM executables which are not patched. This causes problems and can make the system unbootable (this happened to me several times). After installing mirroring you need to re-install *ALL* LVM patches.

ll /dev/vg00/group

Isn't it set to 0x000000?

Do a lifls /dev/rdsk/cxtydz, what do you see?

A sign of a successful upgrade other than a bootable system is no errors are swagentd.log. You should always check that file after an upgrade or (patch) installation.
Are you sure you didn't have this problem before upgrading? I have often seen that problems are found after upgrading or installing patches but have existed long before. You can check with a 'strings /etc/lvmtab' to see if vg00 is there. My guess is it's not. You can then restore the same file from a pre-upgrade backup (to /tmp) and run strings on that. If the latter is OK and the first not you could just replace it if no disk re-config was done during the upgrade. (I would still advise to make a backup copy of /etc/lvmtab first.)
