FYI - starting with SAS Version 8, there are no special requirements in an SMS environment, as was the case with SAS V6 involving pre-allocating multi-volume datasets.
I support several very large MICS and MXG SAS environments, all of which play quite nicely with DFSMS. Also, if you still have GUARANTEED_SPACE=YES specified for SAS databases (feeling that uncomfortable bloat?), change it back to NO, as SAS Support has documented. Do consider that a SAS database needing to be allocated > 65K tracks per volume requires SAS 9.1.3 SP4 plus additional maintenance. It's much easier to use UNIT=(SYSDA,nn) and be aware that the additional volume allocations will have an initial allocation of the "secondary amount" of the first volume's SPACE=(CYL,(pppp,ssss)).
