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.
