A system and method for increasing capacity utilization of non-volatile storage devices within a group of non-volatile storage devices used to store data from at least one attached system are disclosed. A group of data sets is written to a first storage device as part of a write operation such as migration. A plurality of storage devices partially filled with data are designated as substitutes. The write operation to the first storage device is suspended upon receiving a request to read a data set stored in the first storage device, such as occurs in a recall operation. A second storage device is then selected from the plurality of substitute storage devices. The write operation is continued by writing data sets from the group of data sets included in the write operation that were not written to the first storage device to the selected second storage device. The requested data is then read from the first storage device. After data has been read from the first storage device, the first storage device may be designated as a substitute storage device so that the partially filled first storage device may be selected for continuing write operations. Data sets from substitute storage devices may be transferred or merged into a lesser number of storage devices during recycle operations to prevent the number of substitute storage devices from increasing beyond a predetermined limit or goal. Recycling operations in which data sets from different storage devices are transferred or merged may be performed by building a first queue including a list of filled tapes ordered according to the least amount of valid data and a second queue including all unassociated partially filled storage devices ordered by the amount of available storage space, and merging. The non-volatile storage devices may include tapes or tape libraries.
