Chapter 16. Management Tools
16.1. Utility Overview
HPSS provides a variety of command-line utility programs to aid in the use and management of the
system. The programs can be grouped into the following major categories:
16.1.1. Fileset and Junction Management
These programs work for HPSS filesets.
• crtjunction - Creates an HPSS junction.
• deljunction - Deletes an HPSS junction.
• lsfilesets - Lists all HPSS filesets.
• lsjunctions - Lists all HPSS junctions.
16.1.2. Tape Management
These programs manage the life cycle of tapes in the system.
• repack – Consolidates data on tapes by moving storage segments from sparsely populated
volumes to other volumes. The emptied volumes are then available for reuse or removal from the
system.
• reclaim – Re-initializes an empty tape for re-use after repack has emptied it, or after it has
become empty through attrition. Reclaim will not re-initialize a tape that has been retired.
• retire - Marks a disk or tape volume as read-only and not reclaimable.
• remove – Deletes empty disk and tape volumes from the Core Server's metadata, then optionally
exports the volumes from the PVL/PVR.
• recover - Salvages data from damaged volumes by reading from other copies or other levels in
the hierarchy.
These tools deal with shelving tapes:
• shelf_tape - Selects and moves tapes from a tape library to an off-line storage area. Additionally,
shelf_tape can check in tapes that previously existed on shelf.
• shelf_tape_util - perform various administrative functions related to shelved tapes.
16.1.3. System Info
• dump_sspvs - Lists the physical volumes known to a particular subsystem, including statistics
about file aggregates on tapes.
• dumpbf - Lists the storage characteristics of a particular bitfile.
• lsvol - Lists the path names of bitfiles that are located on a disk or tape volume.
• dumppv_pvl - List the physical volumes managed by the PVL.
