I ran this query to determine which management classes are being used
by our clients; select distinct node_name, class_name from backups.

The query itself may be wrong or wrong for the purpose. However, the
output contained a surprise. Several current nodes had management
classes listed with them that are no longer defined, and haven't been
for some years. That is, they do not appear in the output of 'q mg'.

Under what other circumstances could management classes be in the
database, but not in 'q mg' output? The TSM server is at level
5.3.1.4 on AIX.
