Abstract

PURPOSE:To extend a diagnostic function by adding an interface between a power controller and a maintenance diagnosing device to transfer the fault information. CONSTITUTION:The local channel devices 301 - 30n receive the start instruction from an input/output processor 20 and give the transfer instructions to the remote channel devices 401 - 40n based on the channel block stored in a main storage 10. Thus the devices 401 - 40n transfer data between the storage 10 and the peripheral devices 50. A power controller 60 reads the fault information via an interface 1h when the faults occurs at the devices 401 - 40n during the transfer of data. Then the controller 60 reports the fault information to a maintenance diagnosing device 70 via an interface Ii.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing device, and in particular, to a local channel device and a remote channel device connected to a serial interface. Regarding the collection of.

[Conventional technology]

Conventionally, this type of data processing device has a local channel device and a remote channel device via a serial interface, and when a failure occurs in a remote channel device lower than the serial interface, especially when a failure occurs in the serial interface section, detailed failure information is provided. No information could be sent; the only means by which the local channel equipment could detect that a failure had occurred was to do so.

[Problem to be solved by the invention]

The above-mentioned conventional data processing device has a configuration of a local channel device and a remote channel device through a serial interface, and when a failure occurs in the lower remote channel device, especially when a failure occurs in the serial interface,
Since the serial interface of local channel devices is interrupted, it is possible to detect abnormalities, but since there was no way to report detailed fault information of remote channel devices to maintenance diagnostic equipment, it was difficult to collect fault information. there were. Therefore, there is a drawback that it takes a long time to search for a fault.

[Means to solve the problem]

The configuration of the data processing device of the present invention includes a remote channel device that is connected to a local channel device connected to an input/output processing device via a serial interface and performs data transfer with the input/output processing device, and a plurality of remote channel devices connected to the input/output processing device. a power supply control device that controls the power supply of the channel device; and powering on the remote channel device to the power supply control device;
In a data processing device comprising a maintenance diagnostic device that instructs disconnection, a first means detects that a fault has occurred in the remote channel device and retains fault information, and transmits the fault information to the power supply control device. The present invention is characterized in that it includes a second means for transferring, and a third means for transferring the fault information from the power supply control device to the maintenance diagnosis device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a block diagram including data transfer in the present invention.

In FIG. 1, the data processing device includes a local channel device 100, a remote channel device 200, a power control device 300 that controls power, and a maintenance diagnosis device 4 that instructs power on and off of the remote channel device 200.
00.

In the data processing device according to this embodiment, if a certain fault occurs continuously or intermittently in the remote channel device 200, the fault registers 210, 220, 23
0 is set and its contents are transmitted to the signal lines lb, l.
c and ld are set in the failure information register 240, and the occurrence of the failure is also reported to the power supply control device 300 through the signal line 1e. Further, the local channel device 100
A failure of the remote channel device can be detected by interrupting the serial interface 1a.

The power supply control device 300 that has been notified via the signal line 1e reads the contents of the fault information register 240 in the remote channel device 200 via the data line 1f, and then notifies the maintenance diagnostic device 1F 400 via the signal line 1g.

In FIG. 2, the data transfer device is the main memory control device 1.
0, the input/output processing device 20, and local channel device groups 301 to 30.0 under it. , a group of remote channel devices 401 to 4 connected to the serial interface 1h.
01, and peripheral devices 501 to 50f connected thereto
i. A power supply control device 60 that controls the power supply; and a maintenance diagnostic device 70 that issues instructions to turn on and cut off the power.

Local channel device groups 301 to 30 that have received a startup instruction from the input/output processing device 20. The remote channel device groups 401 to 40 . Give transfer instructions to. The remote channel device 40 that receives the transfer instruction from the input/output processing device 20 transfers data between the main storage device 10 and the peripheral device 50. During the data transfer, the power supply control device 60 controls the remote channel group. 40°~40. ．． When a failure occurs, the information is read through the interface lh and reported to the maintenance diagnosis device 70 through the interface 11.

〔Effect of the invention〕

As explained above, the present invention provides means for transferring each fault information in a remote channel device to a power supply control device, and an interface for transferring fault information between the power supply control device and a maintenance diagnosis device, By having a means for reporting the contents, it is possible to expand the diagnostic function.
