If you offsite your database backups, you shouldn't be using DEL
VOLHIST; you should be using the SET DRMDBBACKUPEXPIREDAYS parameter
instead. Doing so will set old db backups to VAULTRETRIEVE status
(rather than directly to scratch), which you then remedy by using the
proper MOVE DRMEDIA commands.

Please review the DRM procedures on pages 560 and following of the TSM
for AIX Administrator's Guide, version 5.1.5.
