Do not use the TSO or the API FlashCopy® functions to copy data sets that you intend to access from the target volume. With FlashCopy, TSO or API usage does not provide any data management services, such as allocation or cataloging. Data sets that are copied using these functions are not accessible from the target volume without the user manually performing these data management tasks. You can use a data set copy program that provides these data management services as part of the copy process, such as DFSMSdss.
