Description of the Invention: [Technical Field] The present invention relates to a server, and more particularly to a server having a first storage controller and a second storage controller, and after the server executes an error return procedure Each resource or service in a state in which the second storage controller is in an idle state can be automatically transferred to the first server storage controller. [Prior Art] Today's world is an era of information technology and the development of the electronics industry. The high-tech products and mobile communication technologies derived from various computers are developing rapidly and are closely related to our lives. It has shortened the interpersonal relationship between people. The distance between time and space. With the current popularity and high usage rate of electronic products (such as computers) and technology (such as Internet) and the encouragement of various manufacturers, the competition in the market is becoming more and more fierce. Manufacturers are constantly pushing new ideas to win new and smart, in order to attract the love of many users. As the requirements of electronic products and communication services are more and more convenient, the future electronic products and communication services can be more convenient. More speedy service has become one of the important indicators for users to evaluate whether high-tech products and communication technologies are leading other countries. The so-called "server" is a high-performance computer. The main function is to act as a node of the network to store or process data on the network. The general server is at least the processor. A hard disk, a note: body and system components, the above components are used in the application of the road: do not make 'the server has higher processing capacity, contribution, reliability, safety, shipability And the riding, especially the county's advancement of information technology and the need for information circulation, and the use of servers to provide relevant information, downloads, mail and other services, has become commonplace, so How to provide a more stable and more user-friendly information usage and service environment, the processing power and stability of the server become one of the most important keys. Based on the above reasons, in order to improve the stability of the server, the developer developed a dual backup storage controller for the abnormal situation of the server due to the abnormal situation of each lion, the data access of the guide (4) or the interruption of the network service. The server of the server has a first storage controller and a second storage controller, and each storage controller transmits or receives a packet between the server and a network, and is responsible for different resources and Services (such as file downloading, sharing, or emailing and other resources and services) to end users. In order to avoid an abnormal situation in the first storage controller or the second storage controller, that is, a resource or service interruption occurs, the server of the dual backup storage controller sets one of the storage controllers to be faulty, and the other The storage controller immediately replaces the failed storage controller to continue to provide a variety of resources and services. For example, when the first storage controller fails, the second storage controller immediately replaces the first storage controller to provide various resources and services, and then, when the first storage controller failure condition is eliminated, the server usually automatically Performing a fail back procedure for transferring the resources and services provided by the second storage controller to the first storage controller, and causing the first storage controller to continue providing resources and Service, and let the second storage controller return to the backup mode. However, during the process of executing the error return procedure, the server often encounters problems such as 1322948 network traffic, device busy (Device busy), etc., causing the server to execute the error return procedure, and cannot access all the items. The resources and services are forwarded to the first storage controller, and thus the administrator of the server is required to operate the manual fail procedure. At this time, the manager must check each resource and service item by item, and can only confirm the second. The resource or service that the storage controller has not handed over to the first storage controller is in the state of being idle after the bear can't idle the second storage controller and has not transferred the resources or services to the first storage controller, and then forwards to the first The controller is stored, and according to the manual return procedure of the foregoing manager, the resources and services are checked again until all the resources and services are transferred to the first storage controller. As described above, the administrator needs to spend a lot of time. Repeatedly checking whether resources and services have been transferred to the first storage controller, and waiting for resources and services from busy records The state transitions to an idle state, causing inconvenience to the administrator in managing the server. SUMMARY OF THE INVENTION In view of the above-mentioned many deficiencies, the inventors have made long-term efforts and experiments to finally design a "method of returning timing errors of the dual-reserve storage controller" of the present invention. The proposal of the present invention can contribute to the public. The object of the present invention is to provide a method for timing error return of a ship with a dual backup storage controller, which is implemented in a value detector including a first storage controller and a second storage controller, After the failback (fail back) program, the resources and services that the second storage controller has not yet handed over to the first storage controller are automatically set as a referral item, and 8

And the regular execution of the program every _- fixed time period, the transfer items that have already been placed in the transfer form will be transferred from the second storage control to the first storage control H, and the transfer items in the busy state will continue to be guaranteed. The county touches the fairy until the mosquitoes are purely programmed, and all the transferred items have been handed over to the first-storage controller, and the feeding device deletes the regular execution program. Thus, the device can achieve the purpose of truly returning from the error automatically. Solving the traditional server requires the administrator to manually operate the manual fail program. For the sake of the review, the reviewer can make a further understanding and understanding of the purpose and technical effects of the present invention. The embodiments are combined with the drawings, and the detailed description is as follows: [Embodiment] The present invention is a dual backup storage controller. The method for timing error return of the server is applied to a server, and the server includes a first storage controller 1 and a second storage controller 2. After the abnormal condition of the first storage controller 1 is excluded, and the server performs an error returning back), the server first checks each resource or service owner list (eg, directory service, current directory service) The active directory service is used to find out the resources and services that the second storage controller 2 has not handed over to the first storage controller 1 from the respective resources or service lists. The server sets the resources and services that the second storage controller 2 has not handed over to the first storage controller 1 as a handover item 3, and establishes a handover table 3 according to all the handover items 30 (as shown in Fig. 1 1322948).

Transfer the project 30 and proceed to the step (1〇). (204) Judging whether there is any transfer item in the transfer table 3, if the following step (201) is performed, otherwise the step (2〇5) is performed; (205) when there is no transfer item 3 in the transfer form 3, delete The program is executed on a regular basis and is over. For example, as shown in FIG. 4, the server includes a first storage controller 1, a second storage controller 2, and four storage units (4, 5, 6, and 7), wherein the first storage The controller manages the first, second and fourth storage units (4, 5, 7), and the second storage controller 2 manages the third storage unit 6, and the server receives the first through the second storage controller 2. The heartbeat signal sent by the controller 1 is stored, and the second storage controller 2 determines whether the heartbeat signal has not been received for a period of time. If the second storage controller 2 determines that the heartbeat signal has not been received for a certain period of time, the heartbeat signal is not received. , indicating that the storage controller 1 has an abnormal condition (as shown in FIG. 5), and immediately all the storage units (4, 5, 6, and 7) are taken over by the first storage controller 2. 11 is not read in Figure 6, when the first storage controller 1's abnormal condition j 'the server executes the fail back procedure, the storage controller i has taken over the first storage unit 4, but Second, quaternary, 7) Wei busy poly m storage controller = miscellaneous tube second, fourth storage unit (5, 7), at this time, still manage the second and fourth storage units by the second system $2 ( 5,?), and the first storage has not been able to take over the second and fourth storage units (5, 7) respectively set to a project 30 ' and thus transfer the project 3G to establish the transfer table 3 (such as the first ττ〇 Establishing a periodic execution program, such that the feeding device is alternately operated for a fixed period of time, that is, the second and fourth storage units (5, 7) are transferred from the second storage controller 2 to the first storage controller i. Until the regular execution of the process f, the two transfer items 30 have been handed over to the first storage controller i (ie, restored to the first ® ®), the ship H is deleted in the same period of execution procedures. Establish the transfer form 3 and execute the regular round of procedures, so that the ship automatically executes the regular execution procedure to place the transfer form 3 in idle The transfer of the item 3 () to the first storage controller 1 will solve the problem that the official waits for the resources and services to be transferred from the busy record I to the idle state, and then transfers the resource or service by manual means, The disadvantage of the storage controller 1 is that it avoids the inconvenience of the administrator in managing the server. According to the above, it is only one of the preferred embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any change or modification of the skilled person in the field of the invention may be covered by the following patents in this case. 12 1322948 [Simple description of the drawing] Figure 3 is the transferred of the present invention.
