Abstract

PURPOSE:To eliminate the troublesomeness of an operation and to improve operability for test diagnosis by storing a bootstrap load channel number when bootstrap load is executed. CONSTITUTION:In case of the execution of test diagnosis of an operation processor EPU 3-1, the bootstrap load channel number is stored in the storage part 91 of a service processor SVP 9 by the storage processing of the bootstrap load channel number. When test diagnosis of an EPU 3-2 is successively performed, the SVP 9 outputs a message onto a console CSL 10 to inquire whether a bootstrap load device is changed or not. If bootstrap load from the same magnetic disk device 7 as preceding bootstrap load is executed, N is inputted as the response to the message, and the SVP 9 takes out the stored bootstrap load channel number to execute bootstrap load from the magnetic disk device 7.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a test diagnosis method for an information processing system.

[Conventional technology]

Conventionally, in testing and diagnosing information processing systems, the designation of peripheral devices used when loading data necessary for initial settings (hereinafter referred to as bootloading) for each logical device is performed using input/output control unit numbers, physical channel numbers, Logical channel number (hereinafter these three will be collectively referred to as the bootload channel number)
Using 9), each time I input a command manually, I performed a boot load and then executed a test diagnosis.

[Problem that the invention seeks to solve]

In the conventional test diagnosis method described above, the bootload channel number is entered by two people, so if an input error occurs, when testing and diagnosing multiple logical devices in succession, it is necessary to input the bootload channel number by two people. However, the same channel number must be entered over and over again each time a logic device is tested and diagnosed.

There is a problem that the operation is cumbersome.

The present invention solves these problems with conventional devices, and eliminates the trouble of manually inputting channel numbers when bootloading from the same device after bootloading. It is possible to prevent malfunctions such as errors in channel number specification, and to improve operability during testing and diagnosis.

[Failure to solve the problem]

The test diagnosis method for an information processing system according to the present invention provides information in which a plurality of logical devices, an input/output control device, a service processor, and a main storage device are connected to a system control device, and an external storage device is connected to the input/output control device. In the processing system, when testing and diagnosing the plurality of logical devices using the service processor, initial setting data including firmware is sent from an external storage device to initialize one logical device selected as a test and diagnosing target. means for storing an input/output control device number, a physical channel number, and a logical channel number that are designated access paths of the external storage device used when loading into the main storage device; and another one of the logical devices. When testing and diagnosing the machine, there is a means for displaying and inquiring on the operation console whether or not the access/guss has changed, and input/output control of the external storage device that will be used as a new loading device if there is a request to change the access/gusus. A means for having an operator specify a device number, a physical channel number, and a logical channel number, and a means for allowing an operator to specify a memorized input/output control device number, physical channel number, and logical channel number if there is no request to change the access address. and a means for emitting the information.

Next, two aspects of the present invention will be described in detail with reference to the drawings.

Hereafter svp)'.

10 is the console connected to SVP 9 (hereinafter C
8L). 91 in the SVP Q is a storage unit that stores the boot load channel number, 92 is an inquiry unit that inquires of the operator via C8L 10 whether or not there is a change in the boot load device, and 93 is a unit in which change in the boot load device is specified. If a change in the boot load device is specified, the designation section 94 allows the operator to specify the boot load channel number that will become the new load device via the C8L 10, and extracts the stored boot load channel number if the change of the boot load device is specified. This is the extraction part.

FIG. 2 is a flowchart of the process for determining the boot load channel number, and the process 9 for storing the boot load channel number.
1', Process 92' of inquiring the operator via C8L 10 whether or not the bootload device has been changed; if the change of the bootload device is designated;

Enter the boot load channel number that will become the new load device.
Process 93' for causing the operator to specify via 8L10
, if a change in the bootload device is not specified, a process 94' for retrieving the stored bootload channel number.
and boot load execution processing 95'.

Next, the operation of the present invention will be explained with reference to two drawings.

First, when testing and diagnosing the EPU 3-1 in FIG.

Since this is the first boot, the boot load channel number is not stored, so after selecting "Yes" to the boot load device change inquiry process 92' in Figure 2, the boot load channel number is It is assumed that the process proceeds to process 93' in which the device is designated as a rake, and the CPU load process is performed from DKU 7 of the second peripheral device. Thereafter, by the process 91' of storing the boot load channel number in FIG.
9 Physical channel number 00 and logical channel number 01 are SV
It is stored in area 91 of P9. After the test diagnosis of EPU 3-1 is completed.

Continuing with the test diagnosis of EPU 3-2 shown in FIG.

According to the process 92' in which the SVP 9 inquires of the operator whether or not there is a change in the boot load device shown in FIG. 1) C8L
It outputs the following message on IO and waits for the operator's response input.

” CHANGE LOAD DEVI CE (l0P
= O, PC=(io, LC=01)? (Y/N
)"If you want to run a server load from the same DKU 7 as last time, in response to the above message, enter °゛N".
Enter. The SVP 9 executes the process 94' to extract the boot load channel number stored in FIG.
．． Extract logical channel number 01.

Bootloading is performed from this bootloading device, that is, DKU 7 (process 95' in FIG. 2). On the other hand, if you want to bootload from MTU 8 rather than from DKU7, enter °゛Y'' as a response to the above message. In that case, SVP 9 will connect to the bootload channel that will become the new loading device in Figure 2. ``ENTER CHANNE''
L NUMBER" to prompt the operator to enter the bootload channel number. The operator should then specify MTU 8 (IOP number 0. Physical channel number 01. Logical channel number 01).
8L Enter more than 10. The SVP 9 performs bootload from the MTU 8 based on this newly designated bootload channel number (process 95' in FIG. 2).

Regardless of whether DKU 7 or MTU 8 is used, after the boot load is executed, the channel number is stored in area 91 in SVP 9 by storage process 91'. Therefore, if the DKU 7 is continued to be used as a bootload device, it will be sufficient to input LLN71 in response to an inquiry to change the bootload device without having to input the bootload channel number every time. Changing the bootload device doesn't happen often, so
In this way, there is generally no need for manual input of the boot load channel number.

〔Effect of the invention〕

As explained above, the present invention stores the boot load channel number when executing boot load.
This has the effect of eliminating the trouble of manually inputting channel numbers multiple times, and preventing erroneous operations such as mistakes in specifying channel numbers, thereby improving operability during test diagnosis.
