Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a computer system diagnostic device for diagnosing a hard disk (hereinafter abbreviated as HD) as a peripheral device will be described. FIG. 1 is a block diagram showing the configuration of the computer system diagnostic apparatus of this embodiment. In the figure, 101 is a CPU card, 102 is a system bus of a computer system, 103 is a peripheral device control card for controlling the HD 104, 105 is a diagnostic process for diagnosing the HD 104, and 106 is execution control of the diagnostic process 105. Diagnostic monitor software, 105a
Is a diagnostic module for opening HD, 105
b and 105c are diagnostic modules for setting operating parameters of the HD 104, 105d are diagnostic modules for writing data to the HD 104, 105
e is a diagnostic module for reading data from the HD 104, 105f is a diagnostic module for comparing data, 105g is a diagnostic module for returning the parameters of the HD 104 to the state before the diagnosis, and 105h is H.
Diagnostic module for closing D104, 107
Is the execution parameter storage area (execution parameter storage means)
It is.

Next, the operation will be described. FIG. 2 is a flowchart showing the operation of the computer system diagnostic apparatus of this embodiment divided into the diagnostic monitor software 106 and the diagnostic process 105. Computer system HD 104
When diagnosing, the operator defines the diagnostic content for the HD 104 in the diagnostic monitor software 106. Specifically, a set of diagnostic modules that constitute the diagnostic process 105 is defined as 105a to 105h (step ST21). Next, the diagnostic process 105 is generated according to the definition of step ST21 (step ST2).
2). This makes the diagnostic process 105 an operable execution module. Next, the number of execution loops, the allowable number of error occurrences, etc. are set for the diagnostic process 105 (step ST23). This is regardless of the content of the diagnostic process
It is a common parameter that must be set for all diagnostic modules. The set parameters are stored in the execution parameter storage area 107. Next, the diagnostic monitor software 106 executes the diagnostic process 105 according to an instruction from the operator (step ST24). Then, the executed diagnosis process 105 controls the execution of the diagnosis according to the common parameters stored in the execution parameter storage area 107 (step ST25).

In this execution control, first, the HD open process by the diagnostic module 105a is performed (step ST26). This is not limited to the diagnostic program and is a process that must be performed in order to use the HD of the computer system. Further, the diagnostic process 105 executes the diagnostic module 105b (step ST27). This is a process that must be executed when it is necessary to carry out a functional diagnosis of the HD without changing the operation mode when the HD is actually operated online before performing the diagnosis.

9). As a result, a heat run test of a diagnosis target that needs to be provided with an execution time interval such as a diagnosis target having a mechanical life becomes possible.

Example 5. In the above embodiment, the parameter input from the operator is performed by the diagnostic monitor software 106.
Has been done only against. On the other hand, in the computer system diagnostic apparatus of the present embodiment, the input of variable parameters (parameters that the diagnostic process does not need to be aware of at all) common to each diagnostic process for controlling execution of the parameter input to the diagnostic process are performed. , Input into variable parameters (parameters used only in the diagnostic process) that are unique to the diagnostic process and that are necessary for advancing the diagnostic process.

FIG. 7 is a block diagram showing the computer system diagnostic apparatus of this embodiment, in which 123a is a variable parameter common to the diagnostic processes 124 and 125, and 12 is a variable parameter.
3b is the unique variable parameter.
