During logical data set restore, this message is issued for a non-VSAM data set to give the following information:

Source tracks:

The number of tracks that were dumped for the source data set.

Target tracks:

The number of tracks in a pre-allocated target data set, or if the target is not pre-allocated, the number of tracks that DFSMSdss allocated for the target data set.

For HFS and PDSE data sets when ALLDATA is specified, if DFSMSdss can determine the amount of used space, it will dump only the used space, regardless of the ALLDATA keyword. When the data set is restored, DFSMSdss allocates the target data set with the source data set's total allocation amount. Therefore, the number of source tracks in the ADR474I message be smaller than the number of target tracks. See the explanation for ALLDATA under 'Explanation of DUMP Command Keywords' in the DFSMSdss Storage Administration Reference for more information about HFS and PDSE data sets.
