Creating an unlabeled tape volume with DFSMSrmm

You can use the EDGINERS utility to create an unlabeled tape volume. DFSMSrmm verifies that the correct volume is mounted, either by reading any existing label or by asking the operator to confirm the external label. DFSMSrmm writes an 80-byte record that is not recognized as any valid label format, however, the DFSMSrmm utility can recognize it as an unlabeled tape once it is initiated.
