Try this....

DELETE VOLHISTORY TODATE=TODAY TOTIME=NOW-9:00 TYPE=DBBACKUP

this all depends on how much dbbackup you what to keep.  I just keep the
latest series that includes a full backup and the incre's that follow it.

The system in question is an RS/6000 H80 running AIX 4.3.3 ML 9, both
on TSM 4.1.3.0 and 5.1.1.0.

The volume history file hadn't been cleaned out in a very long time
(since 1997), and when we went to clean it up with the following
command:
        del volhist todate=12/31/1999 type=dbbackup
It returned saying that it had deleted 55 entries.  When I queried
the volhistory again, the first dbbackup entries were from 1998.
When I issued the command again, TSM reported that 0 entries were
deleted.

The system was installed early last year, and the TSM database was
migrated from an old RS/6000 590 running AIX 4.3.3 at a lower
Maintenance Level.

Any insight into the problem would be appreciated.
