Hi Ian!
Because you can't reclaim DISK volumes. TSM stores files in aggregates which
will only be freed when all files within the aggregate become expired.

Hi Eliza!
You do want several smaller files, rather than a few very large files
because each client session will allocate a volume. File volumes cannot be
used concurrently by more than one session.

Yes, try again. If it works it is a bug (don't tell IBM)!
If data is on a DISK device class and Tape (or file device class) you can

The 5.2.2 Performance Tuning Guide says:
"NTFS file compression should not be used on disk volumes that are used by
the TSM server, because of the potential for performance degradation."
We use client compression so I don't think it would buy us anything.

Thanks. That worked perfectly, and was
True. Seek time is tiny compared to tape mounts. I am just concerned that
the TSM db has to keep track of thousands of volume. How much will it increase
the size of the db. Ours is already 90G at 70% utilized.
