I have not had to work with this type of stuff for some time, but I do think you can turn on/off the concurrent copy function. At one time it was also something that you had to order with the DASD box. Also, I don't think flashcopy needs concurrent copy to do its thing. The z/Os people may have to "turn on" concurrent copy.

Hopefully, someone else can shed some light on it. We have a DS8100 (2107) that we have been using for the past few months for VM based stuff (SFS servers, Linux server, etc) with no problem. I've been using CP FLASHCOPY on it with no problems as well. We just tried to move some z/OS volumes over to it from an old 2105-F20 (Shark). The volumes moved fine. However, when our z/OS guy tried to run z/OS ConcurrentCopy against some of the datasets, he got errors that the box does not support that function. Obviously, it does since we have been doing Flash on VM all along. Now, the z/OS guys are suggesting that I gen the 2107 volumes as "unsupported" in VM to fix the problem. I'm not sure what they mean by that, but I don't like the sound of it. Anyone seen this problem or have any insight into it? Martha
