Change 32 bit to 64 bit Kernel

UNIX HP-UX
1

Hi, I'm using HPUX 11.11 on Vizualize B180L

our productive machines have 64 bit kernel

# file vmunix

vmunix: ELF-64 executable object file - PA-RISC 2.0 (LP64)

I got one test system, which should have the same HW (i was told it is the same HW)

hpuxtest:/stand-->file vmunix

vmunix: PA-RISC1.1 executable -not stripped

how can I change the Kernel from 32 to 64 bit, or isn't it exactly the same HW, because of
PA-RISC 2.0
and
PA-RISC1.1
?

cheers,
funksen

  1. You need to find the actual hardware of the machine you are trying to change. PA-RISC 1.1 code will run on a 2.0 but not vice-versa.

  2. I would only suggest a reinstall of the OS for such a major change as all device drivers, config etc will change.

Check the OS version on that test system 'uname -a'. I think that it will be different from your production systems. And as porter said, any change of this sort should really be an OS reinstall.

thanks for the answers
it's the same oslevel

HP-UX hpuxtest B.11.11 U 9000/778 2001556563 unlimited-user license

HP-UX xxxxx B.11.11 U 9000/785 2004161020 unlimited-user license

so it's not the same hw

I'm coming from AIX side, and there it's no problem to switch from 32 to 64 bit kernel,
but ok I'll reinstall the operating system

does anyone know if 64 bit kernel is supported on PA-RISC1.1 ?
