volser

Specifies the source DASD volume serial number from which dumped data is to be copied. Omission of the LOGICALVOLUME keyword causes DFSMSdss to copy data from all logical volumes in the dump data set. This keyword is useful only if the data being copied was created by a physical data set dump operation from multiple DASD volumes. When copying a logical dump, LOGICALVOLUME is ignored.
