Check all your hardware. You may need to involve your telecommunication vendor to look at their hardware too. Be prepared that they may lie to you their hardware is working 100% You may need to pickup the optical cables and examine it centimetre by centimetre. >At the beginning everything worked well, but in the last weeks some JOBs are failing. And possible loss of data. Errors received will be written on BOTH sites unless you took staged and duplicate write actions. :-( >We have checked all fibers involved in the communication, changed FICON SFPs, and no way to get rid of the message. Good luck with that one. You may need to REPLACE all hardware one by one to elimate the culprit.
