DFSMShsm generates a unique data set name for each dump copy that
it has created through DFSMSdss. This data set name must be known
in order to allocate the dump volumes. If you need to perform a restore
using DFSMSdss directly without DFSMShsm, you need the DFSMShsm-generated
data set name. This name can be obtained by issuing the following
command:
LIST DUMPVOLUME(volser) DUMPCONTENTS
