According to the documentation, after z/OS 2.3 the LFAREA parameter no longer reserves real memory for large frames at IPL. Instead, it's a limit on the number of fixed 1M frames.
Since it's now a limit is there any harm in leaving LFAREA too high as long as you keep an eye on large fixed frame usage and paging? I'm asking because we have some LPAR's with wildly underused LFAREA's and few opportunities to exploit them. The lazy systems programmer in me would rather leave LFAREA alone rather than try to pick a target value that needs to be closely managed.
