Table 1 shows the hardware (marketing device name) and software (MVS™ generic device name) names for tape devices. The MVS generic device names are also the names used by the job control language (JCL) to communicate with the MVS operating system. Because hardware names and software names can be different, we have included Table 1 for your convenience. The following discussions refer to a tape device by its MVS generic device name. Use the MVS generic name for any JCL statements or DFSMShsm commands that specify device names.
