*_RCLM_DATE fields in VOLUMES table

[justgimmeafreakinID]

Has anyone seen these fields actually contain any data?
Here's the description of the fields - I haven't been able to find any reference to them in the infocenter.

From HELP QUERY VOLUME:

Begin Reclaim Period
Represents the date after which the Tivoli Storage Manager server
will begin reclaiming this volume, but not later than the date
represented by the end reclaim period. If, when the reclaim period
begins, there are files on the volume that have not expired, they
will be moved to a new WORM volume during reclamation processing.
This field displays a date only if this volume is in a storage pool
for which the value of the RECLAMATIONTYPE parameter is SNAPLOCK.

If more than one archive is stored on the same volume, the start of
the volume's reclamation period is based on the date of the most
recent archive. For SnapLock volumes, the RETVer parameter of the
DEFINE COPYGROUP command determines how long an archive is stored. If
RETVer is set to 100 days, the volume's reclamation period will start
100 days after the first archive is stored on it. If a second archive
is stored on the same volume, the reclamation start date will be
adjusted to 100 days after the new archive is stored. If the RETVer
value is changed after the first archive is stored, the latest
reclamation date will apply for all of the archives on the volume.
For example, assume RETVer is set to 100 for an initial archive, but
is then changed to 50. If a second archive is stored on the volume
three days after the first, the reclamation period will not start
until 100 days after the first archive was stored.

End Reclaim Period
Represents the date by which the Tivoli Storage Manager must complete
reclamation processing on this volume to ensure continued protection
of the data. It also represents the Last Access Date physical file
attribute in the NetApp Filer, which prevents the file from being
deleted until after that date. This field displays a date only if
this volume is in a storage pool for which the value of the
RECLAMATIONTYPE parameter is SNAPLOCK.
