Flashcopy - restart or reset Flashcopy to original date/time

Flashcopy currently is a one and done function. It would be useful to have the ability to start over or reset a Flashcopy to it's original point and time. For example take a flash copy on Day 1 at noon, run your DR exercise, application test, vendor product test and hours or days after the flashcopy was taken reset back to the original point and time. Restart testing.

    I believe what you're are asking for is essentially cascaded FlashCopy, which the DS8000 and CSM do support. You would need to define one FC session to take the initial Flash, and then a second FC session would flash off the target of the first FC session. It would be the targets of the second session that you would attach your hosts to in order to do your testing. When you want to "reset" the test. You would then reflash the second session which would take the preserved data from the first session and flash it back over the second sessions targets.

    If this is not what you are describing, perhaps we should get on a call and we can discuss further to see if there is a new feature here that CSM needs to implement.
