SAS PROC CONTENTS listing has information about blocks and also blocks-
per-track, also total used and total free. You can span z/OS DASD
volumes either by allocating UNIT=(SYSDA,nn) where "nn" is number of
candidate volumes available, or more dynamically expanding with
STOPX37 or DFSMS DATACLAS. Have a look at the z/OS companion for
multi-volume allocations and also the CONTENTS procedure details.
