TimeFinder/Clone full restore

We had to fully restore data from target devices to source devices, and once it was done, the clone pairs where in "Restored" state. After doing a terminate, I suggested to do a split, the information about de clone sessions was removed.
Now each pair have the same data, but I think the sync was lost.
We created the clone sessions once again and the pairs are in state "Created". There is a script to perform a copy automatically and it begin with a recreate operation.
The question is, is it ok for recreate operation to find those pairs in "Created" state or is there any particular state that will look for?

That's what I was expecting to hear confirmed Paul. It makes perfect sense with my understanding of the underlying functionality.

That's a good question. From what you described I would expect the script to fail on the recreate, because there has never been a full sync (at least not since the pairs were put back together. The best case scenario I can think of is that it might succeed, but force a full copy the first time.

As I understand it, when you terminated, it terminated the differential (SDDF?) session which had been maintaining the state of changes between the devs. When you created the pairs again, even though the data was the same on both, TimeFinder won't know that until after the first full copy and activate.

Someone please correct me if I've got this wrong, as it has been a while since I took the course *lol*

you will need to activate before you can issue the recreate otherwise you will get the error Cannot perform the operation because the device is not in a valid state
