Next, the operation of the resource configuration information management system according to the present embodiment configured as described above will be described.

Here, as shown in FIGS. 1 and 2, resources A, B, C, and D are connected to the data processing device 1, and the resource A is directly connected to the data processing device 1. However, it is assumed that the resource B is connected to the data processing device 1 via the resource A by a bus or the like extended from the resource A. That is, resource B depends on resource A,
It is assumed that the operation of the resource B is not guaranteed unless the availability of the resource A is guaranteed. The relationship between the resources C and D is also the same as the relationship between the resources A and B.

When starting up the system, the user selects whether or not to save the resource configuration information and the dependency relationship information, and starts up the data processing apparatus 1. Then, in the data processing device 1, the ITF is started, and if it is specified to save the resource configuration information and the dependency relationship information, the ITF is started from the resource configuration information creating unit 11 to store the resource configuration information and the dependency relationship information. If it is not specified, it is started from the initialization means 13.

When the resource configuration information creating means 11 is started, the built-in R of the resource A connected to the data processing apparatus 1
The type code, the revision, the group code, and the resource specific information set in the OM, the dip switch, and the like are sequentially read, and the resource setting information A (hereinafter, the resource setting information corresponding to the resources is denoted by the same reference numeral). And get
This is shaped as resource configuration information A and stored in the resource configuration information storage unit 21 (step S101).

Next, the resource configuration information creating means 11 sends a POST (Power-On Self-Test) of the resource A.
(Step S10)
2) It is determined whether there is an error in the execution result of the self-diagnosis program (step S103). If there is an error in the execution result, the resource configuration information creating means 11
Sets an invalid code "03" in the error information in the resource configuration information A in the resource configuration information storage unit 21 (step S1).
04) If there is no error in the execution result, step S104 is skipped.

Subsequently, the resource configuration information creating means 11 determines whether the next resource B exists (step S10).
5) Since there is the next resource B, the control is returned to step S101, and steps S101 to S105 are repeated for resource B to store the resource configuration information B in the resource configuration information storage unit 21.

For the resources C and D, the resource configuration information C and D are stored in the resource configuration information storage unit 21 in the same manner. When the next resource runs out in step S105, the resource configuration information creating means 11 The process ends.

After the processing of the resource configuration information creating means 11 is completed,
The dependency relationship information creating means 12 determines the dependency relationship information A of the resource A.
Is stored in the “pointer to resource dependency information” in the resource configuration information of the resource configuration information storage unit 21 (step S201).

Next, the dependency information creating means 12 acquires the group code of the resource A from the resource configuration information A (step S202), and determines whether or not another resource dependent on the resource A exists (step S202). S203). If there are no other resources dependent on the resource A, the dependency information creating means 12
Sets NULL in "pointer to resource configuration information of dependent resource" (step S204). Since there is a resource B that depends on the resource A, the dependency information creating unit 12 searches the resource configuration information storage unit 21 for the resource configuration information B of the resource B having the same group code (step S205). Resource configuration information B obtained as a result of search
Is stored in the dependency information A of the resource A as a “pointer to the resource configuration information of the dependent resource” (step S206).

Subsequently, the dependency information creating means 12 determines whether or not the processing has been performed for all resources A, B, C, and D (step S207).
Since no processing has been performed for C and D, step S
Control is returned to 201, and step S20 is performed for resource B.
1 to S207 are repeated to store the “pointer to the resource dependency information” in the resource configuration information B, and NULL is set to the “pointer to the resource configuration information of the dependent resource” in the dependency information B. Set.

For resources C and D, as in the case of resources A and B, "pointers to resource dependency information" are stored in resource configuration information C and D, and dependency information C and D are stored. "Pointer to resource configuration information of dependent resource" (in the case of dependency information D, N
(ULL).

When the next resource is exhausted in step S207, the dependency information creating means 12 proceeds to step S2.
Transfer control to 08.

In step S208, the dependency relationship information creation means 12 searches the dependency relationship information storage unit 22, and first,
Acquire dependency information A of resource A (step S20)
9).

Next, the dependency information creating means 12 determines whether the "pointer to the resource configuration information of the dependent resource" in the dependency information A is NULL (step S2).
10). If the “pointer to the resource configuration information of the dependent resource” is not NULL, the dependency information creation unit 12
Acquires the resource configuration information B indicated by the “pointer to the resource configuration information of the dependent resource” (step S211), and further acquires the “pointer to the resource dependency information” from the acquired resource configuration information B. (Step S212) The head address of the resource configuration information A is stored in the “pointer to the resource configuration information of the dependent resource” in the dependency information B indicated by the “pointer to the resource dependency information” (step S21).
3). If the “pointer to the resource configuration information of the dependent resource” is NULL in step S210, the dependency information creating unit 12 skips steps S211 to S213.

Subsequently, the dependency information creating means 12 determines whether or not processing has been performed for all resources A, B, C, and D (step S214).
Since no processing has been performed for C and D, step S
209, and returns to step S for the next resource B.
By repeating the steps 209 to S214, the “pointer to the resource configuration information of the dependent resource” is stored in the dependency relationship information B.

For the resources C and D, a "pointer to the resource configuration information of the dependent resource" is similarly stored in the dependency information C and D.

Then, when the next resource runs out in step S214, the dependency information creating means 12 ends the processing.

The initialization means 13 has two execution timings. One is executed at the time of system startup prior to the diagnosis of POST or the like (including the operation of a self-diagnosis program for each resource). During execution by a user's instruction.

When activated, the initialization means 13 resets the error information in the resource configuration information A, B, C, D of each of the resources A, B, C, D in the resource configuration information storage section 21, The resources A, B, C, and D are initialized to indicate that they are not errors (step S301). That is, the invalid code, bit 1 and bit 0 are all reset to zero.

The comparing means 14 outputs the PO at the time of starting the system.
It is executed every time after the execution of ST.

When activated, the comparing means 14 acquires the resource configuration information A from the configuration information storage unit 21 (step S30).
2) It is determined whether error information of the resource configuration information A is set by POST or the like (step S3).
03).

If the error information has not been set (No in step S303), the comparing means 14 determines the resource setting information such as the type code, the revision, and the resource specific information stored in the internal ROM, the DIP switch, etc. from the resource A. A
Is obtained (step S304), and the availability of the resource A is tested by comparing the resource setting information A with the resource configuration information A and confirming that the resource configuration information A matches the resource configuration information A (step S305). .

As a result of the test in step S 305, if there is a part that does not match, the setting means 15 sets the corresponding error code “00” to “05” to the invalid code in the error information and “1” to bit 0. Is written to indicate that this error is due to the own resource configuration information A (step S307), and a “pointer to the resource configuration information of the dependent resource” is obtained from the dependency relationship information A (step S307). S306).

Subsequently, the setting means 15 sets the dependency information A
Is determined whether the “pointer to the resource configuration information of the dependent resource” is terminated (step S3).
08) If not terminated, the resource configuration information B indicated by the “pointer to the resource configuration information of the dependent resource” is obtained, and “1” is written to bit 1 in the error information (step S309), and By returning the control to S306 and repeating steps S306 to S309, the error information in the resource configuration information B of the resource B that depends on the resource A due to the error of the resource A is also set.

If the “pointer to the resource configuration information of the dependent resource” of the dependency relationship information A is not terminated in step S308, the setting unit 15 performs a test on all the resource configuration information A, B, C, and D. It is determined whether or not the process has been performed (step S310). Since the test has not been performed, the next resource configuration information B is obtained (step S311), and control is returned to step S303 to return to steps S303 to S31.
Step 1 is repeated to test the availability of the resource B, and if necessary, set the resulting error information.

On the other hand, in step S303, the resource configuration information A
If the error information is set, the comparison means 1
4 and the setting unit 15 perform steps S304 to S309.
To skip.

As described above, the comparison means 14 and the setting means 15 basically provide all the resource configuration information A, B, C,
The process is performed for D, but the process proceeds to the comparison of the next resource configuration information without performing the resource configuration information for which error information has already been set. The fact that the error information has already been set before the execution of the comparing means 14 and the setting means 15 means that the results of the execution of the two means for the other resource configuration information do not match, and the resource indicated by the resource configuration information Therefore, the error information is set because the resource configuration information is for the dependent resource. Therefore, executing the comparing means 14 and the setting means 15 is meaningless.

For resources C and D, an availability test is performed in the same manner, and the resulting error information is set if necessary.

After all the above processes are completed, the OS is started. The OS refers to the resource configuration information A, B, C, and D in the resource configuration information storage unit 21 to determine whether each resource can be used during system operation.

When the error information is set for a certain resource as a result of the test by the comparing means 14 and the setting means 15, the search means 16 identifies the resource that caused the error information to be set. It is activated by a user's instruction during operation (if an error is found during operation of the system, the user naturally uses resources (for example, PCI
Board, etc.), the purpose of the search means 16 is to identify the resource that caused the error during the replacement.) Hereinafter, it is assumed that the error in the resource configuration information B of the resource B has been set due to the influence of the error of the resource A.

When the resource B is designated and activated, the search means 16 follows the “pointer to resource dependency information” in the resource configuration information B of the designated resource B, and stores the dependency information storage unit 22. Is obtained (step S4).
01), it is determined whether the “pointer to the resource configuration information of the dependent resource” in the dependency information B is terminated (step S402).

If the "pointer to the resource configuration information of the dependent resource" is not terminated, the search means 16
Retrieves the resource configuration information A indicated by the "pointer to the resource configuration information of the dependent resource" from the resource configuration information storage unit 21 (step S403), and determines whether the error information in the resource configuration information A is set. Confirm (Step S4
04).

If the error information has been set (Yes in step S404), the search means 16 acquires a "pointer to the resource configuration information of the dependent resource" (step S405), and performs a similar search in the error information. Is repeated until resource configuration information for which is not set can be retrieved.

Whether the "pointer to the resource configuration information of the dependent resource" is terminated in step S402,
Alternatively, if the error information is not set in step S404, the search unit 16 determines that the resource A of the resource configuration information A in which the last acquired error information is set is the resource B
(Step S406).

As described above, the search means 16 repeats the search until the resource configuration information in which the error information is not set can be searched, and the resource of the resource configuration information in which the finally obtained error information is set is searched. The resource that has caused the error information in the started resource configuration information to be set is identified.

In the description of the operation of the above embodiment,
The case where the resources are four of A, B, C, and D has been described as an example. However, it is needless to say that the present invention can be similarly applied to the case where the number of resources is three or less or five or more.

In the above embodiment, the “pointer to the resource configuration information of the dependent resource” and the “pointer to the resource configuration information of the dependent resource” stored in the dependency information storage unit 22 are: Although the number is one each, it is assumed that both can be any number. Even if there is more than one,
When an error is set by the setting means 15, error information in the resource configuration information indicated by all "pointers to the resource configuration information of the dependent resources" is set.

[0059]

The first effect is that even if there is another resource whose operation is not guaranteed if a certain resource does not operate normally, access to a resource whose operation is not guaranteed can be prevented beforehand. The reason is that by referring to the resource configuration information by following the dependency information stored in advance, the dependency of the resource can be confirmed.

The second effect is that the time required to compare all the resource configuration information with the resource setting information can be shortened by not accessing resources whose operation is not guaranteed.

A third effect is that it is possible to specify which resource caused the error by referring to the dependency information and the resource configuration information.
