Abstract

PURPOSE:To easily control a controller which plural computer systems share by providing a means which is in one among service processors, which stores the power unit control procedure of a power control part and which executes power unit control. CONSTITUTION:The first service processor (SVP) 1, second SVP 6 and the third SVP 11 are connected to the first computer system 2, the second computer system 9 and the third computer system 12 through a diagnosis control interface. When second SVP 6 receives a supply instruction, it transmits the effect to a power unit control execution part 7. When it receives a power unit control table from a magnetic disk device 8, it executes power unit supply control in accordance with a system identification code received from an automatic power unit 5. Thus, only one power unit controller incorporated in the service processor can be managed in a composite system, and the controller shared by plural computer systems can easily be controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power supply control method for a plurality of systems including two or more computer systems, and particularly to a power supply control method using a service processor.

[Conventional technology]

Conventionally, this type of power control method uses a power control device separate from the service processor (hereinafter referred to as SvP) to control the power supply of the computer system.
(B) 8VPIIC power supply control alt - Even when built-in, each SVP corresponding to a computer system has a power control function, and there is a method of controlling the power supply of the computer system corresponding to the SVP.

[Problem to be solved by the invention]

The conventional power control method for computer systems described above requires a separate power control device if a separate power control device is used.
! Otherwise, the system will be expensive.

In addition, if each SvP has a built-in power control function and controls the power of its own computer system, some devices that make up the computer are shared by multiple computer systems, so it is necessary to turn off the power of the shared device. edge,
This method has the disadvantage that the control of checking the power status of all related computer systems, turning off the power to the shared device, and then turning on the power of the shared device even when the power of one related computer system is turned on is complicated.

[Means to solve the problem]

The power supply control method according to the present invention includes one or more service processors that are connected to a computer system and control maintenance functions of the computer system, and one service processor for each device layer or one service processor for each device layer constituting the computer system. a power supply control unit that is connected to the service processor and controls the power supply according to instructions from the service processor; and a power supply that stores the power control procedure of the power supply control unit in any one of the service processors. It has a control storage means, and a power control execution means which is located in any one of the service processors and instructs the controller IItK of the power control storage means to the power supply control unit to execute power control. .

[Effect]

According to the present invention, it is possible to simply control a device shared by a plurality of computer systems.

Further, the shared device power control section 4 is a power control section of a shared device connected to the first computer system 2 and the second computer system 9. In addition, the second 5 VPS is connected to the power control units 3a to 3d, 10a to 1 via a power control interface (not shown).
Connect to 0d, 13a to 13c. Furthermore, in the first computer system 2 shown in FIG.
and the main memory unit (hereinafter referred to as MMU) 15, and the power supply control unit 3b controls the execution control unit Wt (hereinafter referred to as EPU).
The power control unit 3C controls the power supply of the input/output control unit 61m (hereinafter referred to as OP) 17, and the power control unit 3d controls the power supply of the magnetic tape group (!i) under l0P17. (hereinafter referred to as M'I'U) 18. Also, a magnetic disk 19 is connected to the shared device power supply control section 4.

Next, we will discuss the operation of the power supply control method with the above configuration in the fourth section.
A description will be given with reference to a flowchart from receiving a power control instruction to executing power control shown in the figure. When the pre-specified power-on time arrives, the automatic power-on device 5 issues a system identification code and a power-on instruction corresponding to the second 5VPS. Therefore, when the second 5vps receives the power-on instruction, it notifies the power control execution unit T of this fact. When the power control execution unit T receives the power control table from the magnetic disk device a, it executes power-on control according to the system identification code received from the automatic power-on device 5. Here, if this system identification code specifies a power-on instruction for all systems, the power control execution unit 7 issues a power-on instruction to all power control units in accordance with the power-on order shown in FIG. 3, but in this embodiment, Power control 113a, 10m, 10b,
Instructs 13m and 13b to turn on the power. and,
Taking the first computer system 2 as an example, the power supply control unit 3m receives the power-on instruction and outputs the 5CU 14 and the MMU 1.
Turn on the power of 5, and if the power is turned on normally, the 2nd 5
Returns a response to vpe. Then, this second 5VP6 transmits this to the power supply control execution unit 7. When this power control execution unit T receives a response from all the power supply control units that have issued the power request, it selects the next power supply control unit 3b in the turn-on order.

3e * 10c + Issues a power-on instruction to 1oci and 13c. and the first computer system 2
For example, the power control units 3b and 3c turn on the power of EPolB and 10P17, respectively, upon receiving the turn-on instruction, and return a response to the second 5VP6 when the power is turned on normally. Then, this second svpe transmits this to the power control execution unit 7. When the power control execution unit T issues a power request and receives responses from all the power control units, it issues a power-on instruction to the third power control unit 3d and the shared device power control unit 4 in the power-on order. The power control unit 3d receives the power-on instruction and powers on the MTU 15, and also
The shared device power control unit 4 accepts the power-on instruction and powers on the magnetic disk device 19. In addition, the power supply control section 3d
When the shared device power control unit 4 and the shared device power control unit 4 are respectively powered on normally, the second 5VP 6 notifies the power control execution unit 7 of the shared device power control unit 4 . Next, when the power control unit to be turned on is no longer listed in the table shown in FIG. 3, the power-on operation ends. If the system identification code from the automatic power-on device 5 instructs power-on of the first computer system 2, the third computer system
The power supply control unit 3& is marked with "*" in the column of the first computer system 2 according to the power-on order in the figure.
