Is your disk pool cached? If it isn't, you can ignore the rest of this post.

If it is, that's the problem. Reclamation will use disk-located files in
preference to tape-located files, and the MOVEBATCHSIZE server parameter
gets ignored for disk-located files. (Why? Who knows?) The result?
Reclamation processes will move files from disk to tape one file at a time.
*Slow*.

The fix? Tivoli says a code fix would be "massive". The workaround? Turn off
caching in your disk pools. (I know--it's like curing a hangnail by cutting
your finger off.)
