2. The computer system according to claim 1 , wherein at least one of the plurality of the processing computers has a setting means for setting a mode for prioritizing the processing by the first processing means or a mode for prioritizing the processing by the second processing means, and the management computer stores the mode of the plurality of the processing computers in the storage area, updates the mode stored in the storage area upon receiving a notification of a mode setting by the setting means, and requests the management function processing to the processing computer in the mode for prioritizing the processing by the second processing means.

3. The computer system according to claim 1 , wherein at least one of the plurality of the processing computers has a mode making the processing by the second processing means exclusive, and the management computer requests the management function processing with top priority to the processing computer in the mode making the processing by the second processing means exclusive.

4. The computer system according to claim 3 , wherein the plurality of the processing computers change the mode, based on a load amount which must be processed as the main function processing, or a configuration of the processing computer.

5. The computer system according to claim 1 , wherein, in a case where the request for the management function processing received from the management computer designates an immediate execution, the plurality of the processing computers execute the second processing means without activating the first processing means.

6. The computer system according to claim 1 , wherein, in a case where the request of the management function processing received from the management computer designates an immediate execution, the plurality of the processing computers execute the second processing means, without storing the request in the shared computer, and without activating the first processing means.

7. A control method of a computer system configured from a plurality of processing computers having a first processing means for executing a main function processing and a second processing means for executing a management function processing which is requested from a management computer, and the management computer having a storage area for storing a start time and an end time of an operation of the second processing means of the plurality of the processing computers; wherein the plurality of the processing computers have a first step of notifying the start time and the end time of the operation of the second processing means to the management computer, and the management computer has a second step of updating the start time and the end time that are stored in the storage area to the start time and the end time notified in the first step, a third step of determining whether or not the time requesting the management function processing falls within a time frame of the start time and the end time that are stored in the storage area, and a fourth step of requesting the management function processing to the processing computer having the second processing means that is determined to fall within the time frame in the third step, wherein the computer system further comprises a shared computer connected to the plurality of the processing computers, the shared computer has a fifth step of storing the request for the management function processing that the plurality of the processing computers receive from the management computer, and the plurality of the processing computers have a sixth step of acquiring the request for the management function processing that the shared computer stores and execute the same with the second processing means possessed by the processing computer.

8. The control method of the computer system according to claim 7 , wherein at least one of the plurality of the processing computers has a setting step of setting a mode for prioritizing the processing by the first processing means or a mode for prioritizing the processing by the second processing means, and the management computer has a storing step of storing the mode of the plurality of the processing computers in the storage area, an updating step of updating the mode stored in the storage area upon receiving a notification of a mode setting by the setting mode, and a processing requesting step of requesting the management function processing to the processing computer in the mode for prioritizing the processing by the second processing means.

9. The control method of the computer system according to claim 7 , wherein at least one of the plurality of the processing computers has a changing step of changing a mode for prioritizing the processing by the first processing means, a mode for prioritizing the processing by the second processing means, and a mode for making the processing by the second processing means exclusive, and the management computer has an updating step of updating the mode stored in the storage area upon receiving a notification of a mode change by the changing step, a first processing requesting step of requesting the management processing function with top priority to the processing computer in the mode making the processing by the second processing means exclusive, and a second processing requesting step of requesting the management function processing also to the processing computer in the mode for prioritizing the processing by the second processing means.

10. The control method of the computer system according to claim 9 , wherein the changing step changes the mode, based on a load amount which must be processed as the main function processing, or a configuration of the processing computer.

11. The control method of the computer system according to claim 7 , wherein the plurality of the processing computers has an immediate executing step of executing the second processing means without activating the first processing means, upon receiving the request from the management computer, in a case where the request for the management function processing designates an immediate execution.

12. The control method of the computer system according to claim 7 , wherein the plurality of the processing computers has an immediate executing step of executing the second processing means without storing the request in the shared computer and without activating the first processing means, upon receiving the request from the management computer, in a case where the request for the management function processing designates an immediate execution.
