Boot problem

[Parvin Hosseini_1]

I am not able to boot my machine after mirror activation.

there is something wrong with the boot options on my primary and alternate boot disk.
maybe the problem is with:
lvlnboot -r /dev/... or lvlnboot -b /dev/...

If they are not correctly set, is that any way to boot this machine?

thank you for your help

You can always boot from the Install media and "recover a unbootable system".

Hi Parvin,

you can use your installation CD to boot and then get into maintenance mode and repair your configuration. You can then check what's wrong.

Allways stay on the bright side of life!

Hi:

Can you boot from the original physical disk? Are you trying to boot from your newly created mirror disk? What error do you receive?

Regards!

Hi James

I can neither boot from the main nor from the mirror disk.

the error message is:
/stand/vmunix not found!
this is strange!!

Hi:

I trust that you have a previous kernel, so, you could power off and on the server; interrupt the boot process; interact with the ISL; and do:

ISL> hpus -s /stand/vmunix.prev

Hi Parvin,

do you have an alternative Kernel to boot from? Try to escape the boot sequence, then interact with IPL and run the following command:

IPL> hpux /stand/vmunix.prev

or whatever the name of your kernel copy is.

Allways stay on the bright side of life!

Hi,

Try booting from the old kernel if you have one or else boot from the Recovery CD and try to go to the recovery shell.

ISL>hpux -is /stand/vmunix.old (vmunix.prev)

This doesn't sound like a kernel problem it sounds like a boot string problem. After booting off the install media check your boot string with this command:

lifls /dev/rdsk/

The "boot disk" should correspond with the lvlnboot -b and the output should contain the following:
AUTO MAPFILE SYSLIB (etc.)

If you are creating a bootable mirror you will need to update the LIF volume on the mirror with the mkboot command. There are 2 different updates that you could use. One is for 64 bit and the second is for 32/64 bit. Also the man page for lvlnboot -b option has some specifics that need to be adhered to for the system to boot.

Hi,

When you power on the system Press any key when the " type any key on 10 seconds to stop the auto boot " message appears.

type,

sea ipl

and this will report the drives having the boot kernel. If it doesn't report anything then you have some problems with drives or data in the drive.

Thank you all for your help.

specially James for this command:

ISL> hpus -s /stand/vmunix.prev
