IEHMOVE can be used to move or copy multivolume data sets. To move or copy a multivolume data set, specify the complete volume list in the VOL=SER parameter on the DD statement. A maximum of 5 volumes can be specified. The same number of volumes must be specified for the output data set as existed for the input data set. If the user wishes to consolidate a multivolume data set so that the data set will reside on fewer volumes, the output data set must be allocated on the target volume(s) by the user before moving or copying the data set. To move or copy a data set that resides on more than one tape volume, specify the volume serial numbers of all the tape volumes and the sequence numbers of the data set on the tape volumes in the utility control statement. (You can specify the sequence number even if the data set to be moved or copied is the only data set on a volume.) To move or copy a data set to more than one tape volume, specify the volume serial numbers of all the receiving volumes in the utility control statement.
