Re: hp-ux11iv3 crash on integrity bl870c during os kernel boot

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

Hope this helps!

Re: hp-ux11iv3 crash on integrity bl870c during os kernel boot

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?

Q2 :"Firmware updated on the blades?"

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.

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.

Hope this helps!

Re: hp-ux11iv3 crash on integrity bl870c during os kernel boot

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?

Hope this helps!

Torsten.

Re: hp-ux11iv3 crash on integrity bl870c during os kernel boot

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.

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
Boot path is now: backup/vmunix

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.
