The system attempted to open a volume, but discovered that the volume was not mounted. If duplexing is desired for this initialization, the volume must be mounted.
The system waits for the operator to reply. If the volume is to be provided (GO), initialization continues; the system issues a mount message and uses the data set. If the volume is not provided (IGNORE), initialization continues without duplexing.
Either enter REPLY id,GO and prepare to mount the requested volume, or enter REPLY id,IGNORE.
