Hi,
maybe you modified some kernel parms
now your kernel can't go up
you have to boot with /stand/vmunix.prev

hpux /stand/vmunix.prev

Hi,

Try by booting with alternate kernel.

ISL>hpux /stand/vmunix.prev

To list the files in /stand directory with that you can find any vmunix is stored in other name.

ISL>hpux ll /stand

Hi Try booting thr' previous copy of kernel and also see the /stand directory for kernel's existance.
ISL>hpux ll stand
ISL>hpux /stand/vmunix.prev

I would also suggest you check whether you are booting thr' your regular primary device.
Main Menu> search
Look for potential boot devices and your correct primary device.

In case in all ways you have problem with primary device you can try booting thr' alternate path
MAin Menu> bo alt

Hi Jamshed,

Most probably your kernel has got corrupted. Try to boot from copied kernel(usually it is vmnuix.prev).
Before that from Main menu search for bootable device.
Main Menu> Sea
Check the path.
From main menu> bo alt

Or from ISL prompt check other vmunix in /stand directory by hp-ux|ll /stand
ISL>hp-ux /stand/vmunix.prev

Hope it will work.

The error message gives two possibilities: the file cannot be opened or is not executable.

Before booting from the backup I would go into single user mode and do ls -l vmunix, just in case the permissions have been altered. If they have, chmod +x vmunix then reboot. But check the date on vmunix - if it's recent, it's a new copy and possibly not trustworthy.

The most common cause of this error currently is that the lvm data structures have lost track of the boot lvol.

TO fix this, go to the boot menu.

Type:

boot pri isl

Answer "Y" to "Interact with ISL (IPL) ?"

At the ISL prompt type:

hpux -lm

This brings you into lvm maintanence mode.

At the prompt type:

vgchange -a y /dev/vg00
lvlnboot -v /dev/vg00
[It should say "No boot logical volume configured]
lvlnboot -b /dev/vg00/lvol1
lvlnboot -v /dev/vg00
[It should now say that /dev/vg00/lvol1 is your boot logical volume]

After this, type reboot and the box should come up normally.

Best regards,
