Abstract

PURPOSE:To especially accelerate the working of a magnetic tape device to be mounted in a multiplex processor system which shares a magnetic tape, by displaying the discriminating information to the magnetic tape device. CONSTITUTION:A magnetic tape contains its own display part DSP, and a command given from a display console DSPC is processed at a device controlling part IOMG in a multiplex processor system in which a magnetic device is connected to a central processor with a command. The IOMG refers to a system editing table TAB and transfers the contents of the TAB to the magnetic tape device to display them at the display part DSP. Therefore, a specific central processor connected with a specific magnetic tape can be quickly discriminated.

。Now, as is well known, one of the major features of magnetic tape devices is that magnetic tapes can be used while being exchanged with the device. If no magnetic tape is set in the device, or if a predetermined magnetic tape is not set, the central processing unit notifies the console accordingly. However, this notification only notifies the volume serial number of the magnetic tape to be set, but also provides information such as the name of the job that requires the magnetic tape with that volume serial number, and the name of the central processing unit on which the job is being executed. is not included. Therefore, the operator cannot tell which magnetic tape device to send the magnetic tape with the notified volume serial number just by looking at the magnetic tape device, so he inputs commands from the console and sends the magnetic tape to each magnetic tape device and the central processing unit. The connection status with the device must be confirmed.
