So once again, it's oblivious to change of device type too. As I said, symbolic links are the best of the lot. I'd be using the mirror or restore tricks I mentioned, but moving the data to spaces that are referred to by a consistently named symlink set. We use something like /IFXCHUNKS/$engine/chunkname -> whereever so your future admin work can be merely moving lumps around without touching the engine config at all.
