hp-ux11iv3 crash on integrity bl870c during os kernel boot

[Hassan Yousef]

Hi all i have a problem it seems to me as kernel panic during os booting i attached screen shots for the error
any ideas would be a great assist

[Torsten.]

Was this setup working before? Any recent changes? Did you try to boot the backup kernel?

[Steven E. Protter]

Shalom,

What were you trying to do? Install an OS? If so what EFI command were you using?

Has the system ever worked?

What release of 11vi3? More recent might be better.

Firmware updated on the blades?

Booting of network or local disk?

@Steven E. Protter and Torsten
Yes this setup was working like a charm

Q1: "What release of 11vi3? More recent might be better."

A1: I think it's 11iv3 HA edition release November 2009

Q2 :"Firmware updated on the blades?"
A2 :I'm not sure

Q3 : "Booting of network or local disk?"
A3 : It's booting from local disk

@Steven E. Protter and Torsten

" Did you try to boot the backup kernel?"

Salaam Hassan,

The backup kernel is used to boot the server is cases wherein booting thru the "primary" kernel fails.

Its hard to type the whole procedure. Best look:

Try booting from the backup kernel.

what if i don't want to boot to backup kernel , i want to boot to the original kernel which we did tuning to it for Oracle RAC what procedures do i need to fix the problem mentioned above

[Scott_285]

You might try booting to single user mode and running fsck.

hpux -is

It looks like the system was reset while the config.krs file was being written to.

If you want it or not doesn't matter if the kernel is bad now.

Try the backup kernel.

[Hassan Yousef]

boot to backup kernel failed as there are no backup kernel under /stand just only the original kernel
can i copy kernel file under /stand from healthy system with configuration and replace it on the affected system is there way like this

[Torsten.]

What command did you use to boot the backup kernel?

hpux> boot backup

The problem is, how to copy something if the system does not boot?

[Aungshuman Paul]

At first try to boot the system in single user mode. If it is still fail then try to boot the system from backup boot. It may fix your problem. For boot the system from backup boot:

1. go to Built in EFI shell
2.then execute map command for find out the existing file system. The output should have contain fs0, fs1, blk0 etc.

3. Then type fs0: ( If the system boot disk is internal)

4. then execute ls command for find out the existing file and directory. You will see a dir name backup

5. Now execute " boot backup" command. It may fix your problem.


If you failed to boot the system from "backup boot" let us know. It may require further investigate.

In the meanwhile, you might considering assigning points to those trying to help you out, as an act of encouragement :-)!

Don't you have the lastest Ignite backup?

Hi,

Paul Aungshuman procedure is almost complete.

1. go to Built in EFI shell

2. Then type fs0: ( If the system boot disk is internal)

Shell> fs0:

3. run hpux

fs0:\> ls
fs0:\> cd efi
fs0:\EFI> ls
fs0:\EFI> cd hpux
fs0:\EFI\HPUX> hpux

4. run boot backup

HPUX> ls
backup boot.sys bootconf bootfs current
ioconfig kernrel krs last_install lost+found
nextboot rootconf system system.import system.prev
vmunix

HPUX> ls backup
.config README bootfs krs mod
system vmunix

HPUX> boot backup

Log a call with HP support, to find out what caused the current kernel to not be able to boot.

Your panic says it's not able to find the root disk, can you please check if you have good connectivity to the disk, is it san disk or local disk.
