Abstract:
An apparatus-implemented method according to one embodiment includes detecting an error while writing data to a tape volume, and repositioning the tape in response to detecting the error. Further, the method includes determining, after the repositioning, a current position of the tape, and determining, based on the current position, whether a rewrite of data associated with the error to the tape volume is allowed. A system according to one embodiment includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the foregoing method to occur. A computer program product according to one embodiment includes a computer readable storage medium having program instructions embodied therewith, the program instructions readable and/or executable by a controller to cause the controller to perform the foregoing method.
