Abstract

PURPOSE:To handle automatically a system-down without a human touch as much as possible by providing an alarm processing part for issuing the alarm in accordance with the type of the alarm and the operating state of a system. CONSTITUTION:A processor 50 of a power source control part 5 monitors alarms from interfaces 52 and 53, and grasps the operating state of a computer system 1 when the alarm interruption occurs. Since a trouble is considered due to an abnormal power source system when the alarm occurs at the time of turning on a power source, a fan system of a power source unit 3 is checked to be normal or not. After the system is abnormal to investigate a flag in a memory 51, the unit 3 is turned off through the interface 52 to activate an alternative power source unit 4. When the alarm does not occur at the time of turning on a power source, the action state from a service processor 2 is received and the operation is judged to be under the automatic running. Then, since an operator does not exist, a power source is turned off with respect to the abnormality except a main frame after the JOB termination.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an alarm processing method that performs processing such as turning off the power when an alarm occurs in a computer system, and particularly relates to an alarm processing method that performs processing such as turning off the power when an alarm occurs in a computer system. The present invention relates to an alarm processing method that can execute appropriate processing depending on the situation.

Since the operation of a computer system changes greatly depending on the external and internal environments, these environments are detected in advance and an alarm (8 alarms) is issued when an abnormality occurs. In particular, computer systems have internal circuit elements such as logic circuits and heat sources such as power supply units.
Since the operating conditions are maintained by forced cooling using an air cooling fan, it is necessary to take appropriate measures against changes in the operating environment such as temperature and operating voltage.

[Conventional technology]

Conventionally, temperature sensors, fan rotation sensors,
An overvoltage/overcurrent detector, etc. will be installed to detect abnormalities in the locker internal temperature, air cooling fan, operating voltage/current, etc. and issue an alarm, or in case of a serious abnormality, the alarm will be displayed. Controls such as turning off the power supply unit or switching to an alternative power source were being executed.

[Problem that the invention seeks to solve]

However, with conventional methods, only a warning is displayed, and in the event of a serious abnormality, the only measures taken are turning off the power or switching to an alternative power source. Human countermeasures must be taken, and appropriate countermeasures can only be taken by an experienced person, so if someone other than an expert takes measures, mistakes will occur and the damage will be even greater. There was a problem. Further, even in the case of power off or switching, the process is performed independently of the processing of the computer system, so there is a problem that it is not easy to restart the processing.

[Means for solving problems]

The present invention provides an alarm processing method for a computer system that automatically executes appropriate alarm processing depending on the type of alarm and operating state when an alarm occurs.

Therefore, the present invention includes a computer system including a power supply unit, and an alarm processing section that performs alarm processing depending on the type and operating state of the alarm from the computer system, and the alarm processing section is configured to issue an alarm from the computer system. The present invention is characterized in that when receiving the alarm, the execution of processing of the power supply unit and the computer system is controlled according to the type and operating state of the alarm.

[Effect]

In the present invention, an alarm processing unit is provided that performs alarm processing according to the type of alarm and the operating state of the system, and the alarm processing unit performs retry, alternative control, and disconnection control of the power supply unit depending on the type of alarm and the operating state. control, continuation or forced termination of computer system processing, and control of processing such as transfer of log data, so that as much as possible, there is no human intervention or countermeasures against downtime are processed automatically. .

It is provided within the main power supply unit 3 and supplies operating voltage to the printed circuit board group 13 and the like in response to instructions from a power supply control unit, which will be described later. Similarly, the exhaust fan 40 and
It has an overvoltage/overcurrent detector 41 and a fan rotation sensor 42. Reference numeral 5 denotes a power supply control unit, which has an alarm processing function that controls the power supply unit 3.4 in response to power on/off commands from the service processor 2, and performs alarm processing in response to alarms from the computer system including the power supply unit. 5o is its processor, which executes power control and alarm processing by a program; 51 is its memory, which stores programs and data necessary for the operation of the processor 50; 52 is a power system interface; Yes, it sends power on/off commands to the main and alternate power supply units 3.4, as well as fan rotation sensors 32.42 and overcurrent/overvoltage detectors 31.4.
41 receives the alarm and notifies the processor 5o, 53 is a sensor system interface, which includes an exhaust temperature sensor 11, a smoke sensor 16, and both fan rotation sensors 12.
15 and notifies the processor 50 of the alarm.

Next, the operation of the embodiment configuration shown in FIG. 1 will be explained using the alarm processing flowchart shown in FIG. 2.

First, in the normal power on/off operation, the processor 50 of the power control unit 5 sends a power on/off command to the power supply unit 3 or 4 via the interface 52 based on a power on/off command from the service processor 2. Do it by doing this.

■ The processor 50 monitors the alarms from the interfaces 52, 53 and sends the interfaces 52 and 52 when an alarm occurs.
．． An alarm interrupt occurs from 53.

(2) The processor 50 grasps the operating state of the GI system 1 in response to an alarm interrupt. Therefore, it is checked whether the power is turned on as instructed by itself.

■ If the power is turned on, it is considered that there is an abnormality in the power system, so whether the generated alarm is an abnormality in the fan system of the power supply unit 3, that is, an alarm from the fan rotation sensor 32, or whether the alarm is in the load system or the power system. Overcurrent/overvoltage detector 31 that indicates abnormality
Check to see if there is a warning.

■ In the case of these alarms, the processor 50 determines that the power supply unit 3 is abnormal, checks whether the alternate power supply is available for use by checking the alternate flag in the memory 51, and if it is prepared, the processor 50 determines that the power supply unit 3 is abnormal. 3, turn off the power supply unit 4 for replacement, and return to step (3). On the other hand, if an alternate power supply is not prepared, that is, the power supply unit 4 is not installed, a retry command is given via the interface 52 to restart the power supply unit 3. And the processor 50 is the power system interface 5
monitors the alarm from 2, and when the alarm occurs again, determines that the power supply unit 3 is not normal (abnormal), turns off the power supply unit 3, displays an alarm, prompts the operator to intervene,
Return to step ■. A special display means may be used to display this alarm, or the alarm may be notified to the service processor 2 and displayed on the display of the service processor 2.

On the other hand, if the alarm is not generated again from the interface 52, it is determined to be normal and the process returns to step (2).

■ In step ■, if the alarm is not related to the power supply system, the processor 50 checks whether the alarm is from the sensor system interface 53. It is not caused by an external factor (for example, a system input power abnormality), and an alarm is displayed, prompting the operator to intervene, and returning to step (■).

■ If the alarm is from the sensor system interface 53, check to see if it is the first alarm from the exhaust temperature sensor 11 where the temperature is higher than the set maximum temperature, and if so,
Since the temperature inside the locker RK is abnormally high, an alarm is displayed, prompting the operator to intervene, and the process returns to step (3). On the other hand, if it is not the first alarm, it is checked whether it is from the smoke sensor 16, and if it is the alarm from the smoke sensor 16, it is determined that a flame or the like has occurred inside the locker RK, and the processor 1 turns off the power supply unit 3. In order to do so, an off command is given via the interface 52, and the process returns to step (2). If the alarm is not from the smoke sensor 16, the processor 50 checks again to see if it is a second alarm from the exhaust temperature sensor 11 where the temperature is below the set minimum temperature, and if so, it is determined to be abnormal since the power is being turned on. No determination is made and the process returns to step (2). If it is not a second alarm, it is determined that the abnormality has an unknown cause, an alarm is displayed, prompting the operator to intervene, and the process returns to step (2).

■ In step ■, if it is determined that it is not time to turn on the power, the processor 50 outputs a total of W, and the machine system l earns 1fh.
(Operation) It receives the operation status from the service processor 2 that monitors the status, and detects whether automatic operation is in progress. If automatic operation is in progress, it is detected whether the alarm is caused by the I10 system. That is, in the power supply control device, main body system power supply control and I10
It is controlled separately from system power supply control. The I10 system is HF interface controlled and can be distinguished from the main system. (I10
The system does not exist in this locker, but comes in from the outside via an interface signal. )■If the alarm is 10, there is no abnormality in the main system, so wait for the main system to finish the job.
The service processor 2 indicates the end of the job to the processor 50.
If the alarm is received, the system power supply 3 is turned off and the process returns to the stitching step (2).If it is not an I10 system alarm, the system power supply is immediately turned off and the process returns to the step (2). In other words, if it is automatic driving,
Since there is no operator intervention, if an alarm occurs that causes an abnormality other than the main system, the power is turned off after waiting until the job is completed.

■ In step ■, if the operation is not automatic but is called from another center (computer) and is in remote operation, the processor 50 instructs the service processor 2 to transfer the log, and the service processor 2 sends an error message to the computer system 1. The system transfers the logged log information to the center, notifies the center of the content of the abnormality, turns off the system power supply 3, and returns to step (3).

■ If the processor 50 determines that it is neither automatic operation nor remote operation in steps ■ and ■, it determines that it is manual operation with operator intervention, and the alarm is activated as in step ■.
Determines whether it is caused by the 0 system, and displays an alarm if it is the I10 system.
Prompt operator intervention and return to step ■.

[Phase] On the other hand, if the 11th report is not from the I10 system, the processor 50 uses the sensor 1 via the sensor system interface 53.
It is checked whether the alarm is from 1.16, and if the alarm is from such a sensor system, the process proceeds to step (2) to process the sensor system alarm.

■ On the other hand, if it is not a sensor system alarm, fan system 12.
Check whether it is alarm 15 or alarm 32.42, and check the fan system 12.
．． If it is 15, a warning is displayed and the process returns to step (2). If it is a fan system 32.45 alarm, wait for the job to end and go to step 0 for replacement control.

■ When the job ends even if the job is not for the fan system or for the fan system, the processor 50 checks the replacement flag in the memory 51, and if it detects that there is an alternate power source, it turns off the power supply unit 3 and turns on the alternate power source 4 as in step (■). It starts up, further instructs the service processor 2 to restart the JOB, causes the computer system 1 to restart the JOB processing, and returns to step (2).

@ On the other hand, if it is determined that there is no alternate power supply, the same power supply unit 3 is retried (restarted), and the processor 50 monitors the IF notification from the interface 52 and 53, and when the W notification occurs again, , it is determined that the power supply unit 3 is not normal (abnormal), the power supply unit 3 is turned off, an alarm is displayed, prompting the operator to intervene, and the process returns to step (2). Of course, if it is normal, a warning will be displayed and the process will return to step (3).

In this way, the power supply control unit 5 operates as an alarm processing unit, and controls the power supply unit (off, restart, replacement) and system processing according to the type of alarm and the operating state of the system. .

In the embodiment described above, the power supply control section 5 has an alarm processing function, but it may also have a function related to the service processor 2, and the power supply unit 3.4 may be provided outside the locker RK of the computer system 1. Good too.

Although the present invention has been described above using one embodiment, the present invention can be modified in various ways according to the gist of the present invention, and these are not excluded from the present invention.
