HP-UX 11.23 Not Booting

[Bejoy C Alias]

Somehow the kernel got deleted from the machine, no backups are available. Booted with the 11.23 install DVD and created a new kernel using the system file in the /stand/last_install directory. Now the machine is booting into single user mode always , but if i do a 'init 3' from single user mode , it comes up without any pblm and all the services are coming up. It seems the krs files are corrupted , how can i recover or recreate it.?

Shalom,

Standard has the previous kernel as /stand/vmunix_prev

Now that you are in single user mode cd /stand

cp one of the previous kernels if any to vmuninx and reboot.

If there is no kernel, boot of original OS media and copy the default kernel from there to /stand/vmunix

Then you can rebuild. Hopefully there is enough information to use sam to regenerate your kernel based on the system file that is present.

Like mentioned in the messages, did you try to boot up the server with "backup" configuration?

HPUX> boot backup

man krsd

Last known good KRS files.


Do not you have by any chance any old ignite tape somewhere.

Hi All , i dont have any backup of any working kernel :( . So I want to create new kernel after booting through cd/dvd. I booted the system with DVD1 and imported root vg from the recovery shell, chrooted to the mounted original root, created a new kernel using the last_install system file. But its also throwing the same error.

Is there anyway to create a new kernel if the entire /stand is empty ?
