I am having some problem to reboot our HP 9000 K-class server. When I tried to reboot the system getting a message ???Panic All VXFS mount root failed.??? After that it says system crash occurs

Reboot system and this same thing again and again. . I tried to boot the system into single user mode by interrupting the boot and ?????? pri ISL then ??? ???hpux -is ??? not working, ???hpux ???lm ???is not working. Anybody have any idea . This server is running HPUX 11.0. and I have HP NNM 6.1 on this server. and this is our back up server.

do you have an ignite tape (recovery tape)? If you can not get to single or maintenance mode, you won't get anywhere. Can you get into GSP and check the error logs?

from local console, CTL-B... then sl to get system logs.... take a look for any hints.

if you reboot from installation cd with "run recovery shell", your disks are working??

You need to boot the system from the core O/S cd and use the system recovery option.

- booted into recovery shell
chroot_lvmdisk
cd /ROOT
chroot /ROOT /sbin/sh
vgchange -a y /dev/vg00

- vg00; lvol1, 5, 6, 7, 8
fsck -y -F vxfs -o full /dev/vg00/rlvol? on all vxfs filesystems
- cleaned: lvol5, , lvol6, lvol7, lvol8 had ms

fsck -y -F hfs /dev/vg00/rlvol1 (this is for all hfs filesystems like /stand)

- mount -a; all vg00 file systems mounted;

- lifls -l /dev/rdsk/c?t?d?
- autoboot string ==> "hpux"
- rebooting into single user mode; init 2; init 3
- all vg00 filesystem are mounted; suggest following:
verify the other filesystems, fstyp -v /dev/vgxx/rlvoY and run fsck if needed

This should be a good start post what your results are And I will try to walk you through this.

Hi Eric
With the Core )/S cd with the recovery option, I was able to get up " chroot /ROOT /sbin/sh" after that when I tried to run the : vgchange -a y /dev/vg00" it says vgchange: not found. I was going to open a case with HP today and see whether they will be able to do some thing. If you have any idea what is wrong, any other step I need to run please let me know.

On a recovery shell, you can check only if the disks work correctly (ioscan) but not vgchange it's only a recovery!!!!
