Abstract:
Various embodiments for autonomic reclamation processing for tapes are provided. Instructions are received to perform reclamation processing on the formatted tape. Formatted tape is loaded into a tape drive for buffering active data during reclamation processing and consolidating all of the active data in capacity optimized manner on the same formatted tape. The formatted tape comprises metadata denoting active and inactive data blocks for files. The meta data of the formatted tape is read into a reclamation memory. The table is sorted and a starting block address is sorted. All active files ordered in the table starting at the starting block address are read into the reclamation memory. The files are written from the reclamation memory to the formatted tape from the starting block address and updating the table with new block addresses of the files. The meta data is updated with the updated table.
