Any change booting to single user works?
I found this doc on how to recreate it:
http://h50069.www5.hp.com/e-Delivery3/Forum/Others/UpLoadFiles/99883/vfs_mountroot.txt

But you have to get the server up to the point you can fix it.

Search for "Bad or old data in /stand/rootconf using JFS as root filesystem
" within that document.

Which version of hpux is it?

Ignite might be the only solution. It sounds like it can happen for a few different reasons.

The document you were pointed at is just the right one, i keep it on my desktop ever since i got into that situation.

recovering the rootconf manually is a REALLY frustrating process, so if you have a backup, and it's not a comfy winter evening with much curiosity and nothing else to do, go straight for a recover. either using the rescue mode of the installation cd, or simply ignite.

if you have a backup of the rootconf easily accessible and don't like the rescue mode, you could also attach your vg00 disks to another host and vgimport it to copy in the file.

for your tests, boot to LVM mainteanance mode using hpux -lm at the ISL/EFI prompt to keep boot times low.

Ummm, and for clarity, I think neither single user or LVM maint. mode will work now.

Single user would need successful vg00 activation, and LVM maint. mode needs this very rootconf (and the bootconf if booting off a mirror disk) to mount /dev/root without activating vg00.

any ideas on reaching the SHC people to add a check for rootconf and bootconf validity?

I chose the way more secure. I recovered ignite.
Thanks to all
