JPH1020953A - Shutdown processing system of computer system - Google Patents

Abstract

PROBLEM TO BE SOLVED: To restart the system without any human intervention by performing ON/OFF control over a main power source when application is reset or issues a rebooting instruction. SOLUTION: An SVP 103 which controls the main power source 104 and on an OS, an SVP driver 111 is made resident which always monitor the rebooting instruction and performs the ON/OFF setting of the power source for the SVP 103. After a shutdown process ends, the OS 106 issues the rebooting instruction to a HAL 109 of an interface program and issues the rebooting instruction to the SVP 103. The SVP driver 111 sets the time from when the power source is turned ON to when the power source is turned OFF in the SVP 103 through a CPU 101 and issues an OFF signal 108 to the power source 104. An ON signal 107 is issued to the power source 104 the set time later and then the OS 106 starts. A failure in the reactuation of the system is prevented by completely initializing the values of registers by forcibly powering OFF and ON the system.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique relating to shutdown / reboot and reset in a computer system.

[0002]

2. Description of the Related Art As a conventional technique related to restarting after shutdown, see Microsoft Windows NT Server System Guide, p. As shown in 52, there are a method in which the system is restarted by software without turning off the main power, and a method in which the main power is turned off and on manually when the shutdown of the OS is completed.

[0003]

In a system in which the system is restarted by software, when the OS issues a shutdown / reboot request to the device, the HAL resets and restarts the device. In some cases, the start-up process is executed and a malfunction occurs while the register value is incorrect due to the influence of an operation failure of the application software or the application board.

When such a phenomenon occurs when a restart command is issued from a remote place, the apparatus cannot be recovered from a remote place because the apparatus is malfunctioning.

In the case of a system in which the main power is turned off and on manually, the above malfunction does not occur, but a manual operation is required, so that the presence of a person is required. In any case, the system cannot be restarted when a restart command is issued from a remote place. Therefore, it is necessary to go to the site to restore the device, which requires a great deal of labor.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide an apparatus capable of completely restarting the system after a shutdown process without manual intervention.

Another object of the present invention is to provide an apparatus having the configuration of the present invention, which can change use / non-use of the automatic power-off / on function of the present invention by setting of a user of the apparatus.

It is a further object of the present invention to provide a device which can set the time interval between power-off and power-on optimally.

[0009]

In order to achieve the above object, an SVP for controlling the power supply is provided in a computer system, a reboot instruction is always monitored on an OS of the computer system, and the SVP is issued when the reboot instruction is issued. Software (hereinafter, referred to as an SVP driver) having a function of setting the power of the apparatus to off and on. With this configuration, when a reboot command is issued, the main power of the device is turned off and on, and failure of restart can be prevented.

In the above-mentioned computer system, the SVP driver is provided with a function of enabling or disabling the above-mentioned automatic power on / off function. Turn off the main power when issued,
It is possible to select a method of turning on and perform the operation.

Further, in the above-mentioned computer system, a time setting function for setting a time from turning off the main power supply to turning on the main power supply is added to the SVP so that an optimum time can be selected according to the system configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of the present invention. 101 is a CPU of the computer system device. 102 is a memory of the apparatus. When the OS is started, the OS, the HAL, the SVP driver, and the application are read into the memory and operate on the CPU. An SVP 103 controls on / off of the main power supply. SVP10
Reference numeral 3 has an internal clock and can set the issue time of the ON signal and the OFF signal. 104 is a main power supply of the apparatus. 1
Reference numeral 05 denotes a sub power supply for operating the SVP.

Reference numeral 106 denotes an operating system (O
S), and the CPU 101 is operated by this OS. An arrow 107 indicates an ON signal from the SVP 103 to the main power supply 104, and an arrow 108 indicates an ON signal from the SVP 103 to the main power supply 10.
4 shows an OFF signal. 109 is in the OS 106,
This is the HAL of the program that serves as the interface between the hardware and the core of the OS. 110 is an application program. Reference numeral 111 denotes an SVP driver having a function of turning off and on the power of the apparatus with respect to the SVP 103.

FIG. 2 is a flowchart of a process from receiving a shutdown / reboot request at the time of operating the OS to activating the OS according to the present invention. FIG. 3 is a time chart of FIG.

The processing from (1) to (8) in FIGS. 2 and 3 will be described step by step.

(1) The OS 106 is an application 1
It is monitored whether or not a system restart request has been issued from 10. If it is detected that a system restart request has been issued, the process proceeds to (2). If the request has not been issued, the OS 106 continues monitoring.

(2) Upon receiving a request to restart the system from the application, the OS 106 issues a shutdown / reboot command to each driver to perform a system shutdown process.

(3) OS 10 after shutdown processing
6 issues a reboot request to the HAL 109.

(4) HAL 109 that has received a reboot request
Issues a reboot request to the SVP driver 111.

(5) Upon receiving the reboot request, the SVP driver 111 sets the system time at that time and the interval time from power-off to power-on of the system to the SVP 103 via the CPU 101 for 5 minutes.

(6) If the SVP driver 111 uses the SVP10
3 is issued a main power off command. The SVP receiving the signal issues an off signal 108 to the main power supply 104 to turn off the main power supply 104.

(7) (5) After 5 minutes set at the time of processing,
The SVP 103 issues an ON signal 105 to the main power supply 104 to turn on the system.

Thereafter, when the OS 106 is started, the process returns to (1).

After a shutdown / reboot request is issued by performing the above operations, the system is forcibly turned off and on, and the values of the registers are completely initialized, thereby failing to restart the system. To prevent

[0026]

According to the present invention, the main power is turned off and on when an application issues a reset or reboot command while the OS is operating in the computer system, so that the system can be restarted without manual intervention. Become like

Further, even when the function of the present invention is not required, it is not necessary to remove the SVP or the SVP driver.

Further, since the interval from power-off to power-on can be set, the power can be turned on at a required time and the system can be used.
