The retrieve and restore functions both support the filelist option, which specifies a file containing a list of file names to be restored. I have used this option with restores. The resulting tape mount requests indicated that the files in the list were sorted by location and restored in an order that minimized tape movement (as far as I can tell, this behavior is not spelled out anywhere in the TSM documentation, and can only be discovered by experiment). I have never had occasion to use the filelist option with a retrieve operation, but I suspect that it will cause sorting by location in that context as well.
