Abstract
A copy export application implemented in a computational device receives a request to perform a copy export operation of data and metadata to a selected tape in a tape library coupled to the computational device. The copy export application copies the data from the computational device to the selected tape. The copy export application determines a medium error on the selected tape while copying the metadata from the computational device to the selected tape, subsequent to completion of the copying of the data from the computational device to the selected tape. The copy export application sends a request to a tape control application to replace the selected tape by a new tape and copy the data from the selected tape to the new tape. The copy export application copies the metadata to the new tape.
