Logical COPY processing: The movable source data set's SIZE (in tracks) is not equal to the pre-allocated target data set SIZE. Because REPLACEUNCONDITIONAL and RENAMEUNCONDITIONAL are specified, the target data set is scratched to allocate the extents equal to the source data set.
Physical data set COPY processing: The movable source data set's SIZE (in tracks) is not equal to the pre-allocated target data set SIZE. When invoked through the application programming interface, if the application specifies that it is performing a multivolume recovery of data sets (EI00MVOLRECOV), this portion of the data set is scratched so that the target data set portion can be allocated with extents that have the same size as the source data set.
If the physical data set copy source data set is being copied from the target of a COPY FULL dump conditioned volume, and ALLDATA and ALLEXCP are not specified, the track counts between the source and the target data sets do not match then the system issues this message.
Operation continues. If allocation is feasible on this volume, message ADR396I follows this message. If allocation is not feasible on this volume, message ADR380E or ADR472E or both follow this message.
None.
If reallocation fails, pre-allocate the data set with adequate space, and rerun the job.
