Description

[Detailed Description of the Invention] [Summary] The present invention provides a system power-on device for an electronic computer system having a multi-system configuration.
It has a means to set in advance whether or not to power on other systems at the same time when the power is turned on for each system, and if this setting is made, it is set by IPL (Initial Program Loading) etc. when the power is turned on. This is a multi-system system power-on device that can decode the contents and automatically issue power-on instructions to other systems.

[Industrial application field]

The present invention relates to a system power-on method in an electronic computer system having a multi-system configuration.

[Conventional technology]

In multi-systems in which multiple computers are interconnected, a system power-on method is generally adopted in which when one system is powered on, other systems are also powered on at the same time. .

A conventional example employing the above method is shown in FIG. The power control section of each system is the power-on switch 1.
or 4, IPC (Initial Power Controller) 2 or 5, and UPC (Unit Power Controller) 3 or 6, each system is configured with IPC
2 and 5 are interconnected. When power is turned on by the power-on switch 1 of the single system, the IPC 2 first instructs the UPC 3 to turn on the power. UPC3 is a device that turns on the power of the main unit.
It is activated by input instruction from IPC2. Simultaneously with the above operation, the IPC 2 issues an input instruction to the IPC 5 of the other system via the control line 10. switch 7
If it is on, the IPC 5 receives the input instruction from the IPC 2 and issues an input instruction to the UPC 6.
As a result, the power of other systems is turned on.

Contrary to the above, if power-on switch 4 is pressed, control line 11 is sent from IPC5 to IPC2.
A charging instruction is given by the switch 8, and the
The IPC2 side is powered on.

[Problem that the invention seeks to solve]

In the above system, if the operator wants to power on only one system, the operator can turn on switch 7.
8 (interlocked as shown by the broken line 9), and when it was desired to turn on the power of other systems as well, control was performed by turning on switches 7 and 8.

However, with the above control method, it is necessary to install the switches 7 and 8 in a place where the operator can operate them, and it is also necessary to prevent them from being operated easily, so the arrangement of the switches on the panel must be carefully This has the problem that it requires a lot of time and is prone to erroneous operation.

In order to solve the above-mentioned problems, the present invention has a means for the operator to set in advance whether or not to turn on the power of another system from a keyboard or the like,
When one system is powered on, the above settings are read by IPL, etc., and the system automatically issues power-on instructions to other systems based on that information, making operation easier without the need for a physical switch. The purpose of the present invention is to provide a system power-on device with a multi-system configuration.

[Means for solving problems]

In order to solve the above problems, the present invention includes a multi-power-on setting means 16 for each system and other-system power-on instruction control means 14 and 15 for each system, as shown in FIG.

[Effect]

The operator must set the multi-power-on setting method 1 in advance.
6, it is set whether or not to power on the other system at the same time when one system is powered on. After that, when one system is powered on, the above settings are read out during IPL of that system, and the other system power-on instruction control means 1
Transferred to 4,15. If the setting is made to simultaneously turn on the power of other systems, the other system power-on instruction control means 14, 15 automatically instructs the other systems to turn on the power.

The setting operation by the multi-power-on setting means 16 can be performed directly by the operator from the keyboard while the system is operating, and it is also possible to prevent the settings from being changed easily by adding a password or the like.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail.

{Configuration of an embodiment of the present invention (FIG. 1)} FIG. 1 is a configuration diagram of an embodiment of the present invention. The figure shows each power supply control section (each section divided by a chain line 32) of a multi-system consisting of two computer systems. power on switch 1
The power-on instruction from 2, 18 is the control line 24, 2.
8, IPC (Initial Power Controller) 1
The information is transmitted to the control units 14 and 20 in the controllers 3 and 19. From the control units 14 and 20, SVP (Service
Processor) 16, 22, UPC (Unit Power
A power-on instruction is transmitted to controllers) 17 and 23 via control lines 25 and 29, and
Control unit 1 in IPC13, 19 from SVP16, 22
Setting data 26 and 30 are sent to the terminals 4 and 20.

Registers 15 and 21 are connected to the control units 14 and 20, and the contents of the setting data 26 and 30 are set therein. A power-on instruction is transmitted from the control unit 14 in the IPC 13 of one system to the control unit 20 in the IPC 19 of the other system via the control line 27, and conversely from the control unit 20 to the control unit 14. A power-on instruction is transmitted via the control line 31.

{Operation of the embodiment of the present invention (FIG. 2)} Next, the operation of the embodiment of the above configuration will be explained using the operation flowchart of FIG.

First, operators must
In the SVPs 16 and 22, settings are made as to whether or not to power on the other systems at the same time when one system is powered on. This operation is performed by the operator directly inputting the setting contents from the keyboard, and the setting contents are stored in the form of a setting file or the like in a disk device (not shown) for each system.

For example, when there are four systems, by storing a 4-bit setting flag in a file, it is possible to control the power on and off of the desired system.

After that, suppose that the next time the power is turned on, the power is turned on, for example, from the power-on switch 12 (FIG. 2, S1). This will prompt you to input
The information is transmitted to the control unit 14 in the IPC 13, and the power of the IPC 13 is turned on (S2 in FIG. 2). Subsequently, a power-on instruction is transmitted from the control unit 14 to the UPC 17 and the SVP 16, and first the UPC 17 is powered on (S3 in FIG. 2). This turns on the main unit of the single system. Next, the power to the SVP 16 is turned on (S4 in Fig. 2), and the SVP 16 loads a program at startup from a disk device (not shown), that is, IPL (Initial Program).
Loading) is executed (S5 in Figure 2).

By the above operation, the setting contents are automatically read out in the SVP 16, and the setting data 26 is set in the register 15 in the IPC 13 via the control section 14 (S6 in FIG. 2). If the simultaneous power-on of other systems has been set in advance (multiple power-on), the control unit 14 sets it in the register 15.
, and transmits the power-on instruction to the control unit 20 in the IPC 19 of the other system via the control line 27, and completes the power-on operation (Fig. 2 S
6→S7→S8→S9). On the other hand, if the multi-power-on setting has not been made, the control unit 14 reads it from the register 15 and ends the power-on operation without instructing other systems to turn on the power (the first Figure 2 A6 → S7 → S9).

In the above operation, when the multi-power-on setting is made and the control unit 20 in the IPC 19 of the other system receives a power-on instruction via the control line 27, the UPC 23
Then, the power is turned on to the SVP 22, and the power of other systems is automatically turned on.

Contrary to the above operation, when the power-on switch 18 is turned on, the control unit 20, register 21, SVP
22, and a power-on instruction is transmitted to the IPC 13 of the other system via the control line 31.

〔Effect of the invention〕

According to the present invention, an operator can easily configure multi-power-on settings using a program on each SVP, and can arbitrarily change the settings even while the system is running. At this time, by adding a password or the like, it is possible to prevent the settings from being easily changed by anyone other than the person concerned. Furthermore, since there is no need to implement a physical switch, cost reduction can be achieved.
