May be too late to answer your question. What is messed up on your test partition?
Option 22 restore will only restore system information such as your user profiles, your system values, your printers, hardware configurations (like ethernet cards, dasd, etc.) and your OS libraries. It will not restore any user data – applications, data files for the applications and the like.
Personally, I would review the backup and recovery book – evaluate what from the production system you want to restore, and start from there.
If you have IBM support, they can help you build your restore procedure and mention any ‘gottchas’.
