After reboot my system could not find /stand/vmunix

[Lasse Gandlose]

Hi,
I rebooted my system and after that I was not able to start it up again. It says "/stand/vmunix: cannot open, or not executable"
I have read all the other answers on this topic but unfortunately none has been any help!
If anybody could help me I would appriciate it a great deal :-)

Hi,

Are you able to boot from vmunix.prev?

Lasse, maybe it is corrupted or something. You should try and boot from vmunix.prev. But I'm interested in finding out more about this though.. did you genereate a new kernel before rebooting, or was it more of a maintenance reboot?

Hi,

try to boot from vmunix.prev if can't use the ignite if you have. or else reinstall is the way to get back

[Lasse Gandlose]

I have just tried the following "ISL> hpux -lm /stand/vmunix.prev" with no success! same error as before.
It was more of a maintainse boot! I needed to take a look at a disk and after that I placed it in the same slot and I was not able to boot. I have defenately not done any changes to /stand

Take a look at a disk? Meaning you pulled a root drive?

1 - After turning on the system, when the message "Press escape to stop boot
sequence" is displayed, press the "escape" key to get into the PDC (Product
Dependant Code). A list of available commands will be displayed with
the "BOOT_ADMIN>" prompt.

2 - Type "bo pri isl" and [return] to get to the "isl" command
prompt "ISL>".

3 - Boot from desired kernel.

To boot normally from the previous kernel, type:
"hpux (;0)/stand/vmunix.prev" and [return].

To boot in "single user" mode from the previous kernel, type:
"hpux -is (;0)/stand/vmunix.prev" and [return].

Is your root disk mirrored? If it is, have you tried booting from your mirrored disk?

I'm also interested in finding out what you did exactly when you said you wanted to look at the disk.. did you pull it out? if so, I assume you shut down the machine before you did? Do you have an Ignite tape?

[Lasse Gandlose]

Hi Ross

first no I did not pull a root drive! and since the system was without power and it was replaced nothing should happen! I tried what you said but I keep getting the same error!

Hi Ravi
is it possible for me to only install the missing vmunix from my ignite tape?

Lasse

[Ross Zubritski]

It's ignite time :(

[Ravi_8]

Hi, Lasse

No, with ignite you can't retrieve only vmunix, it's for in need of OS failure.

Since you said that you have removed root disk, could u check wether it's properly sitting in the slot(some loose connections might be).

one more option (i haven't tried this)

ISL> boot /stand/build/vmunix.prev

Lasse --

Here is what I would do:

1) Boot Install Media
2) Select run a recovery shell
3) At the Recovery Main menu, select: RECOVER AN UNBOOTABLE SYSTEM

4) From the next menu, chose: Rebuild a LIF Area Only

DO NOT DO OPTIONS A or B or there will be a lot of recovery work to do later

5) Reboot into -lm mode and see if that works.

If you get into -lm mode at this time, then do:
vgchange -a y /dev/vg00
lvlnboot -v /dev/vg00
Check your boot definitions, you probably will see "No boot logical volume configured". To fix this, type:

lvlnboot -b /dev/vg00/lvol1


IF rebuilding the LIF doesnt eliminate the cannot find /stand/vmunix then :

Do steps 1 to 3 above again followed by:

4) Select the option to DOWNLOAD A KERNEL ONLY

5) Reboot into -lm mode boot and follow those steps again.

Maybe you're not pointing at the right primary boot device. At the boot admin prompt, type in "sea ipl" and see what is returned for bootable devices.

Solved!
Thanks for your help guys! I had to use my ignite tape.
