There's a wrinkle on that DUPMEDBRM operation.
The 'source' system saves to virtual tape. Then the source system sends
it to another system using FTP. The target system then loads it up into
it's virtual tape. Then it does a dupmedbrm to physical tape. Again,
something that's been working for awhile. Well, before our last
unload/reload, which was preceded by some PTF applications.
