Beginning of the base data return
area: For DATA and EXPDATA requests, the following 32 bytes
if requested or defaulted by the DATATYPE keyword will
be returned. They represent statistics that describe
the entire volume. LSPDFOS and LSPDVIRS are not applicable
to volume statistics. |
LSPDEVFS:
Free space statistics
from the entire volume. For volumes with cylinder-managed
space (LSPDCYLM = '1') these statistics represent
space from both the track and cylinder- managed space on
the volume. See LSPDTMFS for statistics from
the track-managed space on the volume. |

LSPDTMFS:
Free space statistics
from track-managed space on a volume for a volume with
cylinder-managed space (LSPDCYLM ='1'). For volumes with
no cylinder-managed space (LSPDCYLM ='0') than these statistics
are equivalent to the total volume statistics described
