A MODIFY TERMDVC command was issued to the device given by device_number that is associated with the session that is identified by session_number, and the session is suspended. XRC was unable to find another device in the session to use in re-suspending the session. This is most likely because all other devices in the session are offline to the system that TERMDVC is being executed on.
The session is left in an active state.
Use the MODIFY SUSSESS command to re-suspend the session.
