I also tried to boot it from EFI Shell by typing fs0: and then HPUX but problem was same. It stucked at above mentioned message. Please help as I'm new to HP-UX.

I don't think you'll find too many HP-UX users here. HP-UX is certified Unix and has significant differences to Linux when it comes to troubleshooting. You might be better checking out one of the Unix forums around the web.
