as the source by SDEVN is copied in the background
to the volume specified as the target by TDEVN. The
relationship ends automatically and the FlashCopy

does not end automatically even when all the data is
copied. To withdraw the relationship, use the
FCWITHDR command. In the following data access
occurs, the data subject to read/write processing is
copied from the source to the target before FlashCopy

source of the specified area (within the extent),

target of the specified area (within the extent), or,
