Hi, Sorry for this very basic question, but i am not a system programmer (just a RACF administrator). When you implement synchronuous (or asynchronuous) copy of your DASD data to a remote site, is it necessary for the remote site to have a z/OS system active? Or is the copy performed at a hardware level between both DASD controllers? Thanks for your help, <snip> No it is not required. And until you issue commands that stop the mirroring (depending on how implemented), the remote site can't have anything but read access to the data, if at all. In the case of a HOT D/R site, the remote processor(s) may be powered, but not IPL'ed. Upon the mirroring being stopped (by commands or by the links being broken for some reason), the "HOT" standby can now IPL. Simple explanation for NON-Tech or someone not deeply involved in remote mirroring.
