Abstract

This invention pertains to the full-volume COPY function of Data Facility Data Set Services (DFDSS). The full-volume COPY function is enhanced to copy the source volume table of contents (VTOC) to a predefined VTOC on the receiving volume while preserving the target VTOC location and its size. This predefined VTOC must be larger than the source VTOC and must reside after the last track of the source volume. The latter is to ensure that the resulting VTOC will not be overwritten with the source data tracks.
