Abstract

PURPOSE:To enable starting a system and to inform an operator of the start even when adapters or peripheral devices different from SG information of OS are present thereon. CONSTITUTION:This system starting system is provided with registers 11-14 storing device information in the peripheral devices 7-10 connected with a CPU, connector number storing parts 17-19 storing the numbers of connectors connected with device information and the peripheral devices in the adapters 2 and 3 which are built in CPU and controls the peripheral device, ID parts 15 and 16 storing packaged location, adapter control parts 20 and 21 reading-out device information, the connector number and packaged location and a memory 23 storing information read out by the adapter control parts and information executed SG by OS inside SVP I. When difference between physical connection information and SG information is present at the time of starting the system, the system informs a console of the difference.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral device system startup method.

[0002]

2. Description of the Related Art Conventionally, when a CPU is started up, the presence or absence of an installed adapter and a connected peripheral device is checked according to SG information registered in the OS to start up the CPU.

[0003]

In the conventional system start-up method described above, if there is an adapter or peripheral device different from the SG information of the OS during start-up, the system may not start up, and the operator may not be started up. There was a problem that there was no way to tell it immediately.

[0004]

According to the system startup method of the present invention, a register for storing device information is provided in a peripheral device connected to a CPU, and an adapter for controlling the peripheral device is provided in the CPU, A connector number storage section for storing the device information and a connector number to which the peripheral device is connected; an ID section for storing a mounting location;
An adapter control unit for reading the device information, the connector number, and the mounting location is provided, and the information read by the adapter control unit and the SG are stored in the OS in the SVP.
A memory for storing the stored information is provided, and when there is a difference between the physical connection information and the SG information when the system is started up, the console is notified.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. A service processor (hereinafter referred to as S
1), two adapters 2 and 3 that control peripheral devices, and an adapter 5 that controls a disk 4 in which an OS is stored. SVP 1 and each adapter 2,
A diagnostic bus 6 is connected between 3 and 5.

Under the adapter 2, two peripheral devices 7 are provided.
And 8 and there are two peripheral devices 9 and 10 under the adapter 3. Here, the peripheral devices 7 and 8 are the same type, and the peripheral devices 9 and 10 are different types.

In the peripheral devices 7, 8, 9 and 10, there are 1-word registers 11, 12, 13 and 14, and the upper bit side of each register 11, 12, 13, 14 is the device type and the lower bit. The side stores the device number. In addition, ID sections 15 and 16 indicating slots of cages mounted in the adapters 2 and 3, connector number storage sections 17, 18 and 19 to which I / O cables are connected, and adapter control sections 20 and 21. And exist.

A control unit 22 and a memory 23 are present in the SVP 1, and the memory 23 is divided into an SG information storage unit and a physical connection information storage unit.

The control unit 22 of the SVP1 when the system is started up
Issues a command for physical connection information to the adapters 2 and 3, and the adapter control units 20 and 21 issue similar commands. This allows the registers 11, 12, of the peripherals 7, 8, 9, 10 to
The device information stored in 13 and 14 is read and written in the physical connection information storage unit in the memory 23 in the SVP1.

Next, the values of the connector number storages 17, 18 and 19 and the IDs 15 and 16 in the adapters 2 and 3 are read out and written in the physical connection information storage in the memory of the SVP 1. On the memory 23, ID for each adapter 2 and 3
Part, connector number, device type, device number.

Further, with respect to the adapter 5 and the disk 4 in which the OS is stored, the same mechanism as described above exists, and the physical connection information is read.

When the adapter is inoperable or the peripheral device is faulty (inoperable, power is not turned on, etc.), the physical configuration information cannot be read out. Therefore, a response is returned even if the SVP1 issues a read out command. I can't come. In this case, SVP1
Is considered physically absent.

Next, the SVP 1 reads the peripheral device SG information of the disk 4 in which the OS is stored and writes it in the SG information storage section of the memory 23 in the SVP 1. The content of this SG information is composed of a device type / number, a connector number, and a slot ID number, similar to the physical configuration information.

The control unit 22 of the SVP1 compares the values of the physical connection information storage unit of the memory 23 and the SG information storage unit. If the comparison result is equal, it will rise without problems,
If not equal, the SVP 1 displays SG information and physical configuration information of the target adapter and peripheral device on the system console or the like.

The operator can detect the misconnection by identifying it. Further, the startup at the time of SG work (changing SG information) is performed by a startup method without looking at the physical connection information.

[0017]

As described above, the present invention compares the physical connection information of peripheral devices with the information stored in the OS, and reports the result, so that an erroneous connection can be found at an early stage. Has the effect of enabling the startup of
