Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a remote control method for an information processing device equipped with a service processor, and in particular, a personal computer is connected to a console interface line of the service processor, and information processing by the service processor is performed. This invention relates to a method for remotely controlling devices.

[Conventional technology]

In recent years, the amount of data processed by information processing devices has continued to increase, and there is a trend from a single computing center to a plurality of distributed computing centers. In this case, a request is generated to remotely control information processing devices in distributed computing centers from a central monitoring center.

In this case, the conventional technology is to use a communication control processing device (CCP) between the information processing devices of the monitoring center and the distributed center to execute the job.
on the Control Processor) via a communication line, and a console that functions as one of the terminals of the information processing equipment is connected to the communication control processing equipment on the monitoring center side, and this terminal console is used to control the remote distribution center. A method of operating the O8 of an information processing device is known.

A method for collectively managing failures of information processing units (central processing units) of distributed computing centers at a monitoring center is described in, for example, Japanese Patent Laid-Open No. 281539/1999.

[Problem to be solved by the invention] In the above-mentioned conventional technology, since the communication control processing device is generally managed on the O8 of the information processing device, the ○S T PN (Ini-tiaJ
There was a problem in that the terminal console could not be used until the Program Loader (Program Loader) was started up normally and the communication control processing device could be used. In addition, when the information processing equipment at the distributed center fails and the O8 goes down, it cannot be restarted (system reset, IPL operations, etc.), and there is a problem that cannot be resolved using only the terminal console at the monitoring center. there were.

An object of the present invention is to easily implement system reset, IPL, etc. from a remote monitoring center by operating a service processor included in an information processing device from the monitoring center.

[Means for Solving the Problems] In order to achieve the above object, the present invention connects a personal computer to a service processor of an information processing device installed in a distributed center via a console adapter device, and connects the personal computer to the service processor of an information processing device installed in a distributed center. A personal computer at a monitoring center is connected to a personal computer at a distributed center via a communication line, and control information (data, commands, etc.) is transferred from the personal computer at the monitoring center to a personal computer at a distributed center via a communication line. The information processing device is controlled by the service processor by the personal computer at the distribution center passing information to the service processor.

[Operation] A console display is usually connected to the service processor, and the service processor can perform system reset, IPL, etc. by pressing a key while looking at the display screen. Replace this console display with a console adapter device. Then, a personal computer is connected to the console adapter device, and the personal computer and a personal computer at the monitoring center are further connected through a communication line.

The console adapter device plays the role of a protocol conversion device, and from the service processor of the information processing device, it looks the same as a conventionally connected console display, and therefore its operational responses look the same. This console adapter device has a built-in memory, stores data sent from the service processor, and can also read the data from a personal computer connected to the console adapter device. Conversely, it is also possible to store data sent from a personal computer and read it from the service processor. Data can be transferred between the personal computer connected to this console adapter device and the personal computer at the monitoring center using a so-called personal computer communication format.

An information processing device equipped with a service processor outputs console screen data assuming that a console display is connected to the service processor. The console screen data is transferred to the monitoring center personal computer via the console adapter device, personal computer, and communication line. The operator of the monitoring center looks at the console screen of the personal computer and inputs desired control information (data and commands). The control information is transferred to the service processor through a route reverse to that described above, and the service processor executes system reset, IPL, etc. based on the control information. In this way, it becomes possible to control the information processing device by operating the service processor from a remote location.

Set the SVP request latch 24. When the SVP request latch 24 is set, the personal computer interface control circuit 22 issues a memory read request to the personal computer 3 via the personal computer interface line 2a.

When the personal computer 3 receives a memory read request from the console adapter device 2 side, the personal computer 3 reads the data area 23 of the memory 23 through the personal computer interface control circuit 22.
The SVP console screen data is read from 1 and sent to the personal computer 6 in the monitoring center via the modem 4, communication line 10, and modem 5. The personal computer 6 displays the sent data as is on the display. The operator of the monitoring center looks at the SvP console screen displayed on the display of the personal computer 6 and inputs desired control information to control the information processing device 1 of the distributed center.
