    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

    Steps would be

    > symclone -g terminate

    > symld remove [-force]

    > symld -g add dev

    > symclone -g create

    Refer the steps @ http://www.rajeshvu.com/san/articles/Simple-Clone-Operations

    You could terminate the clone session, remove the source devices from DG if required and perform a create session with the new source to target

    actually i want to remove Source and Target devices and then i want to delete Clone Device group.

    For that am follwing steps

    >symclone  -g terminate.

    >symld -g remove dev

    >symbcv -g dissassociate

    and finally

    >symdg delete -g -force

    if i remove the target device from the clone group ,the target device does'nt contain the data right..?

    but if i want to reuse the BCV device for new clone seesion ,

    directly i can associate the bcv to new device group..?

    Yes, clone device group is only to manage the session. it does not stop you from reusing your already disassociated BCV again and data is not wiped from source and target when you remove it from the clone device group.

    and yes you can associate the bcv to the new source once it is disassociated
