The volume that a new data set resides on is determined as follows:
- For system-managed DASD data sets, either by the:
- Storage class for the new data set, specified on the STORCLAS
parameter of the DD statement or selected by an installation-written
automatic class selection (ACS) routine.
- VOLUME parameter, specified on the DD statement for the new
data set if the storage class is GUARANTEED_SPACE=YES.
- For data sets on a system-managed tape volume, either by the:
- Storage class for the new data set, specified on the STORCLAS
parameter of the DD statement or selected by an installation-written
automatic class selection (ACS) routine.
- VOLUME parameter, specified on the DD statement for the new
data set.
- For non-system-managed data sets, by the
VOLUME parameter, specified on the DD statement for the new data
set.
