Cannot boot HP-UX 11i system after kernel recompilation

[Rui Vilao]

Greetings,

I have changed the smmax parameter of the kernel.
Now when I boot, I get:

panic: kalloc: out of kernel virtual space.

Now I’m trying to run a recovery shell from the install CD.
Is there some documentation about the steps I’ll have to run to restore the previous kenel?

Any help/suggestion is highly appreciated.

TIA.

Kind Regards,

Rui V

Hi,

Your OLD kernel is by itself preserved while compiling new kernel. Try to boot it from the same. Once done after backing up that change parameter to a suitable value.

While botting press any key within 10 secs when message appears. On PDC type "bo pri" Select Y when prompted for interacting with IPL. On IPL Menu give "hpux ls -l". It will list all files in /stand. Try botting with something like vmunix.prev or whatever listed in above output.

HTH,
Devender

Hi Rui

Interrupt the boot process to go to IPL and then try to boot from /stand/vmunix.prev or /stand/vmunix.bak if created before.
