Apparently not always true.  We have our disk pool defined with
migproc=2.  Disk pool does get dumped to multiple tapes.  When we
start the backup stgpool with maxpr=2, it usually starts copying 2
input tapes to 2 output tapes.  But we occasionally see a media wait
situation where both processes want to copy from the same input tape.
TSM Support told me this is normal.
