You can use the FLASHCPY WITHDRAW command to release CFCSE relationships. However, you cannot specify the MODE(COPY) parameter.

Specify the RELATSPACE parameter to release the allocated area of the TSE-VOL.

The valid parameter combinations cannot be changed. If you specify an invalid parameter combination, the FLASHCPY WITHDRAW command will end normally and perform no action.

The following table describes the parameters and the acceptable combinations of the FLASHCPY WITHDRAW command. See the following table and specify any other necessary parameters.
