Use the DISCFREE utility to display information about disk volume
fragmentation and the allocation of transient and permanent space
on the disk. DISCFREE also shows total volume space capacity, as well
as disk allocation for single volumes or for the whole system.
Transient space refers to temporary, fluctuating volume space.
Permanent space is volume space set aside for job/session temporary
files, permanent disk files, and operating system directories and
other data.
DISCFREE displays disk allocation data only for mounted
MPE/iX volumes, and not for unmounted or scratched volumes. (If
necessary, use the DSTAT command to identify currently mounted volumes.)
