When you terminate the relationship between the source and the target, there would be no SDDF session. You stated that SRC-TGT were in Copied state. This means that you have point-in-time copy of the data when last establish(activiate) was run against the SRC-TGT device pair.  Device Group is only a logical entity to manage the device pair to perform the operations.  Once you terminate the relationship, the data would be still there on the BCV device, but since no SDDF session would be present, you can create a relationship with the new source to the present BCV.  To answer you query -- YES. you can associate the BCV to the new device group and use it to for a Clone session once you terminate the relationship
Hi all,  What is the procedure to follow to delete clone group and to reuse target device for new clone session.?  the existed clone session was in copied state.   Thanks And regards.
