Attention: If output image copy data sets are dynamically allocated as generation data group (GDG) data sets, the oldest generation data set is deleted when the maximum number of generation data sets is reached. This is true even when the Image Copy function or the Create Image Copy function fails to create image copies successfully. For more information, see Attention: Oldest GDG data set might be deleted.
