This looks good, but I would still create these volumes using define vol
numberofvol rather than letting TSM create them.

Subject: Re: [ADSM-L] copypools on disk on AIX?
Yes, thank you.
After posting my question I went to the 5.3 Admin Ref and saw I needed a
file type device class for copypools. Defined then, changed the script,
and since TSM saw them as a new copypool it copied all the data over,
over this past weekend. about 2 TB of copypool data.
We just have the large volumes ( that are RAID5) on a DS4800. TSM auto
creates the volumes:

We tried file device class with our onsite pool with disappointing
results.
I believe the problem was our decision not to stripe across LUN's.
This
would have made performance much better, at the cost of a LUN failure
causing more damage than if we used them indicidually. Now, I can't
remember the last time I saw a LUN failure, but YMMV. We will probably
address this issue again when the decision is made to move our copy pool
to disk.
