If the lpar is still running, then you can get all of the information and rebuild the profile...
lsdev |awk '{print $1}'|xargs -i lscfg -vl {}
If you have lots of drives or virtual adapters, your setup will probably be a little bit more difficult.
If your lpar is shutdown and the profile is deleted, then you're SOL... Your only option is to try to piece together the LPAR again.
Good luck!
