Paging space and virtual memory

The vmstat command (avm column), ps command (SIZE, SZ), and other utilities report the amount of virtual memory actually accessed because with DPSA, the paging space might not get touched.

It is safer to use the lsps -s command rather than the lsps -a command to look at available paging space because the command lsps -a only shows paging space that is actually being used. But the lsps -s command includes paging space that is being used along with paging space that was reserved using the EPSA policy.
