TAPEDSN DEL
The TAPEDSN DEL function allows an administrator or authorized user to delete an occurrence of a data set. A user that is not a system administrator requires TAPE access for the pool that owns the volume(s) associated with a data set in order to delete the data set. If more than one occurrence of the data set exists then the VOLSER of the first volume associated with the data set is also required.
When a data set occurrence is deleted, all of the volumes that were associated with the data set have the use-status set from USED to FREE.
