If VTAM® requires operator assistance to create a connection to a physical unit in a local SNA major node, VTAM displays a message indicating that a connection request was denied because the physical unit is offline. The connection request remains pending and the operator should either allow the connection request to complete by making the device available, or disallow the connection request by entering a VARY INOP command for the physical unit.
