Abstract

PURPOSE:To avoid power-off of indefectible devices due to operator's erroneous judgement to improve the maintainability of a system by providing a check mechanism, which checks validity, for operator's judgement related to power-off. CONSTITUTION:An information processor consists of a table 1 where resources of respective devices are managed by an OS, a checking circuit 2 which checks the validity of operator's power-off, a display device 3, a local state detection signal line 100 as the detection signal line which detects whether each device turns off the power source independently or not, and a resource management table read signal line 101. When the circuit 2 detects that the operator will turn off the power source of each device in the system independently of the other devices in this constitution, the table 1 is retrieved through the signal line 102 to check whether the device, whose power source will be turned off, is removed from the object of resource management or not. When it is not removed, the validity of power-off is detected by the circuit 2 to give a warning to the operator through the display device 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device, and particularly to prevention of failures due to erroneous operations by an operator.

[Conventional technology]

When a failure occurs in an individual device within an information processing system, when replacing parts to recover from the failure, it is necessary to turn off the power to the failed device before replacing the parts.

Conventionally, the determination of which device has failed is made only by the operator. The operator isolates the faulty device from among a group of devices with almost the same appearance based on the nameplate, installation location, etc., and turns off the power to the isolated device.

[Problem to be solved by the invention]

In the above-mentioned conventional information processing apparatus, isolation of a faulty device is performed only by the operator's own judgment, so there is a possibility that power to healthy devices other than the faulty device may be turned off.

As a result, during the operation of the entire system, if a failure occurs in a device that does not cause the system to stop operating even if a failure occurs, or if the system is in degraded operation, the entire system can be shut down by turning off the power to a healthy device. There is a risk of suspension of operation.

In view of the above points, an object of the present invention is to provide a function to check the validity of an operator's judgment regarding powering off a device, thereby eliminating the possibility of powering off a healthy device due to an operator's erroneous judgment, thereby improving the maintainability of the system. This provides an information processing device with improved performance.

[Means to solve the problem]

The configuration of the information processing device of the present invention includes a disconnection information holding unit that holds disconnection information indicating whether or not to turn off the power of each information processing device in the information processing system, and means for checking deletion from a resource management table by the OS of the device whose power is to be cut off based on the above information, and when disconnection information of devices other than the device deleted from the management table is held in the disconnection information holding means; , and means for checking the validity of power cutoff by displaying a warning via a display device or the like.

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

FIG. 1 is a block diagram of one embodiment of the present invention. The information processing device of this embodiment includes a resource management table 1 for each device by the OS, and a validity check circuit 29 for power-off by the operator.
Display device 3. A local state detection signal line 100 is a detection signal line for determining whether or not each device independently disconnects the power supply.
．． It consists of a resource management table read signal line 101 based on O3.

If the power supply disconnection validity check circuit 2 detects via the local state detection signal line 100 that the operator has placed the power supply of each device in the system in a state in which the device itself is to be disconnected, the power supply disconnection validity check circuit 2 performs resource management by the OS. Table read signal line 101
The OS searches the resource management table via the OS to check whether the device that the operator attempts to power off has been removed from the OS's resource management.

If the device the operator is trying to power off is running
If the resource has not been removed from the resource management, the power-off validity check circuit 2 displays a warning to the operator via the display device 3.

〔Effect of the invention〕

As explained above, the present invention provides a mechanism to check the validity of an operator's decision regarding powering off a device, thereby eliminating the possibility of powering down a healthy device due to an operator's erroneous judgment, thereby increasing the maintainability of the system. There is.
