Hope you don't take this in the wrong way, but it's not that easy, there are so many different ways to set-up hacmp and as many again for lpar.
There is no one answer and we would need a lot more info and time to be able to help. I'd advise training - if your manager expects you to do this without any he's a fool. You could also read the Redbooks but again it will take time / trial and error.
If you have any specific questions please feel free to ask but I and I guess most other people on TT AIX would love to be able to help out but the subject is so indepth we would be here for days.
