You are correct, it is the license option in smit - "smitty chlicense"

By default I believe it is set to 2.  If you are on 4.3.2 or below, then
you will have to pay for additional licenses (at least that's how it is
on a regular AIX box).  Now on AIX 4.3.3 IBM has provided an unlimited
license system, yes you will still have to license them on the system,
but it is no longer a chargeable item.
