I think a combination of Metro Mirror and Remote Copy can do the work. It means, you can mirror TSM database to the shorter distance by Metro Mirror and use long distance Remote Copy at appropriate time. It is a little bit complicated, but it should work properly.

But: AFAIK you can't do that with TSM 6.1. It will mirror logs, but not the DB. And this customer is doing very long distance (hundreds of miles) mirroring over PPRC (or the EMC equivalent), which has to be asynchronous. In order for TSM to do the mirroring, you need the drive/filesystem to appear to be a local device to the TSM server. I don't have that option right now, all I've got to play with is the hardware function.
