PA-RISC based server use in ISL:
ISL>hpux backup/vmunix

Re: Secondary Kernal
This can be done by checking available configurations with kconfig as said by the other forumers. However, you can do this on your shell or you can do it on the ISL prompt. On the shell kconfig -v would show you all configurations except current.
Remember on v2 and v3 operating systems, the following are by default,
/stand/current/vmunix
/stand/backup/vmunix
/stand/last_install/vmunix
and you will also have a nextboot kernel as well as a /stand/crashconfig/vmunix if you have crash dumps configured.
On the ISL prompt type ISL> hpux ls to see the contents of /stand and available kernels and then load it with the complete path of the kernel as the firmware of PARISC cannot traverse /stand and find the kernel but the integrity server boot loader can!! and hence you see the previous posts state :-
ISL> hpux /stand/backup/vmunix
HPUX> boot backup
The complete path and just the name!
