Any ideas.. or am I going to have to do a manual install from cds.

The main problem here is the "VFS_MOUNTROOTs failed" error. Check this: http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=271306

Also, as mentioned in the message, the dump device is either not configured or too small. But, that is not the main issue here.

It seams like some damages happened to your root disk.

I advise you reboot and go the lvm maintenance mode and fix the problem by using lvlnboot command

If you need further information in detail , pls let me know the model of your server

I think the HPVM release notes @ http://docs.hp.com/en/T2767-90005/T2767-90005.pdf has the info you are looking for.

"Extending a logical volume backing a guest root corrupts guest:
There is no safe way to extend a logical volume (LVM or VxVM) used as a backing store for a guest root disk. If you do this, the guest panics on its next reboot with the following error:
System panic: all VFS_MOUNTROOTs failed: Need DRIVERS.
The guest root device has been corrupted, and you must reinstall the guest's HP-UX operating system."
