Using a tape library dataserver to support DFSMShsm mount activity reduces the necessity for some DFSMShsm messages, such as messages to the operator confirming that the correct tape is mounted. This type of message is no longer produced by DFSMShsm. However, if a hardware problem causes the tape library dataserver to only be usable in manual mode, DFSMShsm continues to display these messages as before. The TAPEOUTPUTPROMPT on the TAPECOPY command is only valid when the tape library dataserver is operating in manual mode.
