Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for monitoring switching of input/output devices of an information processing system.

Conventional input/output device switching monitoring devices do not detect abnormalities when switching a large number of input/outputs as in the present invention.

Therefore, when switching a large number of inputs and outputs, it is difficult to know whether the switching has been completed as specified unless the operator checks all the connection states.

An object of the present invention is to shorten the switching time of a large number of input/output devices in an input/output device switching monitoring device of an information processing system;
The purpose is to quickly detect switching abnormalities and the details of the abnormality.

The feature of this invention is that a large number of input/output devices are automatically switched sequentially for each group, and switching abnormalities are detected by comparing the switching designation information and the connection state after switching for each group, and When this is detected, the switching designation information for that group is displayed on the monitor display section, and the switching connection state is displayed on the actual display section before stopping.

Here, a group refers to a group of one or more input/output devices connected to a processing device.

Here, the input/output device refers to an input/output control device directly connected to a processing device or an input/output device containing an input/output control section.

The type of each input/output device that belongs to the same group is arbitrary, but in reality it depends on the type of input/output device (input/output control device), such as a disk controller group, magnetic tape controller group, or line printer group. It is common to group them.

Embodiment of the Invention As shown in FIG.
, a monitor section 2 which changes the actual connection status according to the operation contents according to instructions from the operation section 1; a monitor display section 3 which displays the monitor contents and operation contents; A transmission/reception control section 5 that receives the connection state, a real display section 6 that displays the actual connection state, and an abnormality detection section 4 that detects a switching abnormality based on the switching control information of the monitor section and the actual connection state of the transmission/reception control section 5. Consisted of.

Furthermore, the operating section 1 and the monitor display section are arranged on the δ operation panel 11 as shown in FIG. 2, and the actual display section 6 is arranged on the display panel 12 as shown in FIG.

Simultaneous switching refers to sequentially switching all groups from one processing device (for example, CPUA) to another processing device (for example, CPUB) for each group.

When simultaneous switching is designated by pressing a button on the operation panel 11, the monitor unit 2 transmits the switching control information of the first group to the input/output device through the transmission/reception control unit 5 according to the designation.

After a certain period of time has elapsed after the transmission, the abnormality detection unit 4 compares the actual connection status from the transmission/reception control unit 5 and the switching control information from the monitor unit 2, and if they match and the switching is normal, responds. Then, the monitor unit automatically switches to the next group without operating a push button.

In the case of abnormal switching, it will stop at the group that was just sent.

At this time, each display is displayed on the group designation 8 of the operation panel 11 in Fig. 2, the monitor display 9, and the actual display section 10 of the display panel 12 (Fig. 3), and by comparing these displays, the details of the abnormality can be detected. can.

When it is desired to perform a subsequent switching operation, by pressing the transmission switch on the operation panel, the current switching of the group in which the abnormality has been detected is left as is, and the switching operation of the next group is proceeded to.

In this way, the above operation is continued until the next switching abnormality occurs or until all switching is completed.

With the configuration as described above, the following effects can be obtained in the present invention.

1) The switching time is reduced by controlling the switching of a large number of input/output devices for each group.

2) Abnormalities are detected for each group, and the content of the abnormality can be compared between the monitor display and the actual display for each group, which simplifies the monitor display circuit and allows the content of the abnormality to be detected quickly. ing.

Claims (1)

[Claims] 1. In an input/output device switching monitoring device having an operation section for specifying switching of input/output devices, a monitor display section for displaying the contents of the input/output device switching specification, and an actual display section for displaying the actual connection status of the input/output devices. , automatically switches multiple input/output devices sequentially for each group using one touch operation, and detects switching abnormalities by comparing the switching specification information and the connection state after switching for each group. Further, when an abnormality is detected, the input/output device switching monitoring device displays the switching designation information of the group on the monitor display section, and stops with the connection state after switching displayed on the actual display section.
