It's also useful to note that full packs are not required for page and spool. Using minidisks on the 2nd level system and formatting them with ICKDSF using the same labels as the real volumes gives you a disposable page and spool area that you can cold-start at will w/o risking any real data. My 2nd level test systems run with only about 200-400 cyls of each defined.
It'd be really helpful for that stream-oriented SPXTAPE to show up someday...
