------ =_NextPart_001_01C5DA40.EA6BD628 Content-Type: text/plain Most of the disk boxes actually do operate this way -- the OS tells the box what to mirror and the box does the work. The question is how to set up and control this function. In the worst case, you can go to the disk box console and configure the function from there, but that's kind of a kludge. z/OS has the tools to set up and configure this function inside the OS because the storage vendors won't sell the boxes if z/OS doesn't support it. VM could have those same tools if IBM and the other storage vendors decided to provide them. Ditto with Linux. Thanks to all who have replied. Let me explain what I had envisioned. I a mentioned DS8100, but it could be a DS8000. I'm looking for the capability for a local DASD subsystem to mirrored off site to the same type of DASD subsystem and that it be done concurrently. The idea is that this "mirroring" is going on 24/7 and should the main site get hit with a disaster, the off site DASD subsystem would be current up to the point in time of the disaster. I would prefer the two DASD subsystems manage this "mirroring"( or what ever you want to call it) by themselves. That is, no operating system, z/VM, VSE or z/OS has to do it. It seems to me the o/s has better things to do then doing this "mirroring" function, but if it must, it must. Is there such a solution?
