Converting non-VSAM data sets to multivolume

Programming Interface Information

The number of volumes allocated for certain VSAM and non-VSAM data sets can be changed with VOLCOUNT keyword options. The output data set must be SMS-managed. Single volume data sets can be converted to multivolume; multivolume data sets can be converted to single-volume; or the number of volumes allocated for multivolume data sets can be changed. Allocation depends on which VOLCOUNT keyword is selected, and on whether output volumes are specified.

Note: You cannot use the VOLCOUNT keyword to convert the following types of data sets to multivolume:

TTR-BDAM or unmovable data sets. If DFSMSdss encounters an existing multivolume TTR-BDAM or unmovable data set, a DADSM error occurs.
Partitioned data sets (PDS or PDSE). If an existing multivolume PDS or PDSE data set is encountered, it is converted to single-volume.
You cannot restore a non-SMS-managed non-VSAM single volume data set that was dumped with DFSMSdss to multivolume.
