Chapter 16. Management Tools16.1. Utility Over view
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. Additionall y,
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 Inf o
•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.
