Ron, There are options in z/OS to PAGEOUT (PGSER OUT) virtual storage, which essentially is volunteering to have your pages placed on aux storage before stealing occurs. The pages are actually only written to aux if there is a shortage of real storage. This process is asynchronous. Similarly, when bringing the same blocks of virtual storage back in, the pages can be brought back in via PAGEIN (PGSER LOAD) in anticipation of their use to avoid a page fault.
