Hi,
It is near the same. You have to enter isl and execute command:

ISL> hpux -is boot disc(w/x.y.z;0)/stand/vmunix

where w/x.y.z is the physical hardware path to the device, identifying bus converters, slot numbers, and hardware addresses and n is the minor number or section of the disk where vmunix resides.

You could see the content of stand directory with command:

ISL> hpux ll /stand

Borislav

-Boot your server
-Enter in the EFI SHELL ( use arrows in the menÃ¹ )
-type the command "map" ( you will see a list of devices, the boot device you should consider is something like fs0 or fs1, accordingly to the position of the boot disk in the server )
If you don't understand the output of map, try the various fsX: and type "dir" to see if there is the EFI partition ( it probably means that is a boot disk )

-type "fs0:" ( for example )
-type "cd efi"
-type "cd hpux"
-type "hpux.efi"

It will appear the HPUX> menÃ¹.

-type "boot -is vmunix" ( single user mode )
or
-type "boot -lm vmunix" ( LVM Maint Mode )
or
-type "boot vmunix.prev" ( kernel previous mode )
or
-type "boot vmunix" ( normal mode )

Rgds,
Alex
