The only way I can think of figuring this out (and this is what I've done
in the past)
is to update the dsm.opt with the verbose option.  Then look at the
dsmsched.log.
The only sql tables which I can think of which reference files and bytes is
the
backups table and the summary table.  Unfortunately there is no correlation
between the filename (backups - ll_name) and the bytes transferred.
However,
this information is logged in the client schedule log when verbose is
specified in
the dsm.opt file.

If anybody else know of an alternate method I too would be very interested.

Thanks, but, I am looking for file-level information.

I have the "bytes transfered per node" info from the SMF ACCOUNTING
records generated by the server. I can tell HOW MANY BYTES WERE TRANSFERED
for this node, back to the day it first started talking to TSM. I need to
know what files and how big.

Try,
select  sum(bytes) from summary where entity='SuspectedAbuser' and
activity
='BACKUP' and start_time between '2002-01-13 00:00' and '2002-01-14 00:00'

This will give you in bytes the amount of data  a particular node sent to
the server in a 24 hour period.
Adjust the start_time and entity as required.

You can also do a
select entity, sum(bytes) blah blah blah blah group by entity
This will give you the bytes for all nodes.

Hope this helps.

I already tried that. The information it gives isn't detailed enough. It
just tells me about the filespaces.

I need to know specifics, such as the names/sizes of the files/objects in
the file spaces.

Anybody have any sql to do such ?

Thanks, anyway !

Do a "q occ <nodename>" and look for what file systems are out on your
diskpool in great quantity.
That is, if you send all data first to a diskpool and then bleed it off to
tape (daily).
That will give you an idea of what file systems are sending the most data,
currently.
Then you may perform something like a "show version <nodename>
<filespacename> to see each specific item.
        you might note the "filecount" in the "q occ" listing to see how
much will be displayed in the "show version" command.

hope this helps...
        later,
                Dwight
