LFAREA does of course only generally hold fixed large pages, although it
does also handle overflow of PLAREA when that becomes full, which maybe
what you were thinking.
LFAREA (Large Frame Area) provides frame space for both fixed and
pageable large pages. We specify:
LFAREA=7782M, Large frame area
which is more than enough for our needs. Right after IPL I see some
fairly small numbers:
D VS,LFAREA
IAR019I 13.56.52 DISPLAY VIRTSTOR 507
SOURCE = 20
TOTAL LFAREA = 7782M , 0G
LFAREA AVAILABLE = 7257M , 0G
LFAREA ALLOCATED (1M) = 0M
LFAREA ALLOCATED (4K) = 311M
MAX LFAREA ALLOCATED (1M) = 0M
MAX LFAREA ALLOCATED (4K) = 311M
LFAREA ALLOCATED (PAGEABLE1M) = 214M
MAX LFAREA ALLOCATED (PAGEABLE1M) = 214M
LFAREA ALLOCATED NUMBER OF 2G PAGES = 0
MAX LFAREA ALLOCATED NUMBER OF 2G PAGES = 0
Of course, these numbers grow over time...
