Abstract
A tool for tape library hierarchical storage management. The tool mounts a tape cartridge to a tape drive to satisfy a recall request. The tool determines there is available tape capacity on the tape cartridge to migrate data from a migration queue during recall operations. The tool sends a locate end of data (EOD) command to the tape drive. The tool receives a longitudinal position (LPOS) range returned from the tape drive. The tool determines the migration queue is within the LPOS range. The tool writes data from the migration queue to the tape cartridge within the LPOS range.
