Description

[Detailed Description of the Invention] [Summary] This is a control method for copying an old version of information to a new version of system control information such as a support processing device of an information processing system. Version number z of the copy processing program to be used
and the version numbers y and x of the old and new system information, and if x≦y=z, copying is allowed.

[Industrial application field]

The present invention relates to a table copy control method when an old version of information is copied to a new version of system control information of a support processing device of an information processing system.

The support processing device is a device that connects to each component of the information processing system and executes system monitoring, testing, initial microprogram loading, IMPL, etc.

For their control, support processing units are
System control information consisting of a control information table based on the configuration of each system and the specifications of the constituent devices is stored in, for example, a floppy disk storage medium.

[Problems to be solved by conventional technology and invention]

BACKGROUND ART After the components of an information processing system are installed as a user's system, improvements or performance enhancements are often made.

In such a case, a storage medium is created to store the new system control information related to those improvements/enhancements, but information related to the system configuration of each system is stored in the support processing device of each system. The new version is completed by copying the required information from the previous system control information, modifying and editing it if necessary.

When system control information is revised in this way, changes in the types of devices that can be installed in the system, changes in the number and capacity of devices, increases and decreases, etc., changes in control items due to performance enhancement, etc., or changes in the system control information itself. The structure of system control information generally differs depending on the version due to improvements in the structure of do not have.

For this reason, the copying program that performs the copying described above is usually created each time a new version of system control information is published, and the copying program that performs the copying described above is created in accordance with the new version of the system control information, and the copy program that performs the copying described above is created based on the system control information of that version and previous versions. The configuration is such that the information of the part is extracted and the extracted information is copied to each corresponding position of the system control information of this new version.

The reason why the copying program also copies between new versions of the same version is for convenience when making copies, and the reason why the copying program does not only copy the previous version is based on the user's request. This is because they generally support multiple generations of older versions concurrently.

Therefore, when creating a certain version of system control information using a copy program, it is possible to set the input/output storage medium and select the copy program incorrectly.
Or, if you execute a copy without intentionally making the correct settings, correct system control information may not be created, or system control information may be improperly obtained. Conventionally, there are simple methods to prevent such accidents. No means were provided.

[Means for solving problems]

The figure is a block diagram showing the configuration of the present invention.

In the figure, 1 is a floppy disk storage medium on the copying side, and 2 is a new edition floppy disk storage medium on the copying side, each of which has version number records 3 and 4 in its storage information.

Both storage media are connected to the support processing device 5 by respective drives so as to be accessed by a copying program 6 running on the support processing device 5.

[Effect]

The copying program 6 uses the usual method to check whether the storage medium is legal or not, and then reads the version number records 3 and 4 of both storage media 1 and 2. x them,
y and the number of program versions in the program is z
Then, it is checked whether the relationship x≦y=z is satisfied, and only when this condition is satisfied, the copying process is started. That is, a copying program 6 with the same version number is provided corresponding to the revision of the storage medium, and the version number y recorded in the version number record 4 held in the second storage medium 2 is
is equal to the program version number z held in the copying program and is not older than the version number x recorded in the version number record 3 held in the first storage medium 1, copying is performed.

Through the above control, the old version storage medium that was previously used in the information processing system is correctly set on the copy input side, and the new version storage medium is correctly set on the output side, and also corresponds to the new version storage medium. Copying is managed so that copying is performed only when a new version of the copying program is executed.

〔Example〕

In the figure, when execution of the copying program 6 is started, in step 10 of the process, volume label information (hereinafter referred to as label) 7 and 8 of both storage media 1 and 2 is read, Check if it is a medium.

If at least one label is incorrect, the control is advanced to the error processing section 11, an error is displayed on the display device 12, and the process ends.

If the volume is correct, process step 1
In step 3, whether the device model information stored in the device indicates a valid model is checked by referring to the control information in the program.

If the model is valid, in step 14, version number record 3 of storage medium 1 of the old version (its content is x) and version number record 4 of storage medium 2 of the new version (its content is y) are read. , and the program version number held in the program (its value is z), it is checked whether there is a relationship x≦y=z.

Only when the version number satisfies the above relationship, the copy processing unit 15 starts processing, reads out the required information from the system control information stored in the storage medium 1, corrects it if necessary, and stores it. By outputting to medium 2, new version system control information is created.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in the process of updating system control information in an information processing system, the relationship between the old and new versions of the system control information of the copy source and the copy destination, and the copy program itself are updated to the new version. The consistency of the versions of the three parties is also confirmed, and the copy is executed only if the confirmation is successful, so the content of the copy process is guaranteed and the reliability of the system is ensured. That is,
This has a significant industrial effect in that it is easily and automatically guaranteed without relying solely on reliable operation by an operator.

Claims (1)

[Scope of Claims] 1. Extracting each predetermined portion of information from the system control information of the first storage medium of the information processing system, and extracting each of the extracted pieces of information in the system control information of the second storage medium.
