First off, in all versions of HP-UX prior to 11.00, the kernel is always 32-bit. That being said, on 11.x systems, there are several ways to determine whether you're running a 32 or 64 bit kernel...

From the command-line $ getconf KERNEL_BITS or $ file /stand/vmunix

/stand/vmunix: PA-RISC1.1 executable ---> 32-bit
/stand/vmunix: ELF-64 executable object file ---> 64-bit

From SAM
1) goto Performance Monitors -> System Properties -> Operating System
2) check OS Kernel Width: value

That's all!
