Notes? Are you using the TDP backup agent, or just the regular filesystem
client(dsmc)?
I assume dsmc.
So, backups happened...
then migration from DPOOL to TPOOL...
And now you're doing a "COPY STGPOOL TPOOL COPYPOOL" and seeing small files.
Well, MAXSIZE=5G means that during BACKUP, files over 5GB go direct to tape.
Maybe that happened OK.
Then migration put ALL the files, large and small, to TPOOL...
... and now COPY STGPOOL shows you some small files being sent. Looks
normal.
What you might do differently is
First: COPY STGPOOL DPOOL COPYPOOL
Then: COPY STGPOOL TPOOL COPYPOOL
The second COPY STGPOOL will not bother to copy files that the first one
found on disk - i.e. TSM understands that DPOOL -> TPOOL is a hierarchy and
can be treated as one pool.
(In fact if you have a big enough diskpool to catch all your incremental
backups, the second command will do nothing.)

Subject: maxsize threshold for disk storage pools
I have a disk pool that has maxsize set to 5gb. The following stats relate
to data migrated from that tape pool to the offsite pool. I took a few
snapshots to see what size files are being sent to the tape pool that should
have gone to disk. As you can see there seem to be files that were sent to
the tape pool to the offsite pool that are under that size.

Disk pool stats this morning show there is data out there.

/adsmstg05/diskvol.05 NOTES_DPOOL DISK 32,000.0 58.7 On-Line
There is plenty of room, 90+gb, in the disk pool. Yet it seems as though
small files are going direct to tape. If the maxsize is changed I always
thought it would take without restarting the server.
Is there something I'm missing here?
