Thanks all, conclusions: To transfer file from one SYSPLEX to another SYSPLEX, we can use Flashcopy or Shadowimage, so different SYSPLEX read/update different volumes. Yes, it is safe, but we have to change our TWS application procedures to do Flashcopy.
We must buy CA-MIM, or use GRS to convert enqueue to hardware reserve, if I what to use shared DASD between SYSPLEX, even I only use shared DASD to transfer file.
