    Remove the mirror you don't want (rmlvcopy), and then re-create it later with mklvcopy when you want it back.

    I think you can use the chlvcopy command to mark one of the mirror copy as a "split copy".
    If necessary you can then rejoin the copy.
    Further details in the command documentation.
