Description of the invention: [Technical field of the invention] The present invention is a server, especially a server having a first storage controller and a second storage controller, and after the server executes an error return procedure 'Automatically transfer the resources or services in the second storage control state to the first server storage controller. [Prior Art] °° In today's world-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The distance between time and space. With the popularity and high-level of electronic products (such as computers) and communication technologies (such as the Internet), and the various incentives of various companies, the rhetoric in the market is becoming more and more fierce. All major manufacturers continue to push Chen domain, with new and smart, to attract the love of many users, _ system and rail service requirements are getting higher and higher, the future of electronic products and rail services are more convenient and more Fast service has become one of the important indicators for users to evaluate whether high-tech products and communication technologies are leading the country. According to the so-called "Server" (Server) is a high-performance computer whose 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 a processor and a hard disk. The components of the disc, a memory and the thread are formed smoothly. The aforementioned components are specially formulated to enable the server to have higher processing power, stability, reliability, security, scalability and manageability, especially with current information. Technology 200821860 The advancement of technology and the demand for information circulation are increasing. It is common practice for companies or organizations to use the emblem to provide relevant information, downloads, emails, etc. Therefore, how to provide more stable and more user-friendly information. And the service Wei, Wei II where the power and enthusiasm is one of the most important key. Based on the above reasons, in order to improve the stability of the feeding device, the manufacturer developed a dual backup storage controller for the abnormal situation caused by various HI devices, resulting in servo (10) data access or network service interruption. The server and the server are respectively provided with a first storage controller and a second storage control benefit, and each age control || each transmits or receives a packet between the server and the network, and is responsible for different resources and services. (such as: file download, sharing or email and other resources and services) to the end users. In order to avoid an abnormal situation caused by the first storage control H or the second storage controller, that is, the resource or service interruption occurs, the server of the dual backup storage controller sets one of the storage controller failure days π ' In addition, the storage controller immediately replaces the faulty storage control to continue to provide various resources and services. For example, when the first storage controller occurs, the storage controller immediately replaces the first storage controller to provide various resources and services. After the first storage controller failure condition is eliminated, the server usually Automatically executing a fail back program 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 the service, and let the second storage controller return to the backup mode. However, in the process of performing the error return procedure, the feeding service often encounters problems such as 200821860, 罔路ML ML, and device busy recording (j)evice bUSy), etc., causing the server to execute the error return procedure, and It is impossible to transfer all the resources and services to the first-storage controller, so the administrator of the server needs to operate the manual fail procedure. At this time, the manager must check each resource and service item by item, and Only after the second storage controller has not transferred the parent to the resources or services of the first storage controller, after the idle state, the second storage authority and the resources or services that have not been transferred to the first storage controller can be Transferred to the first storage controller, and in accordance with the manual return of the aforementioned official, re-examine various resources and services until all resources and services are forwarded to the first storage controller, as described above It takes a lot of time for the manager to check repeatedly whether the resources and services have been transferred to the first storage controller and wait for the resources and services to be transferred from the busy status. State, causing inconvenience f managers in the management server. SUMMARY OF THE INVENTION In view of the above-mentioned many deficiencies, the inventors have made long-term efforts and research and finally 'designed' the side of the "the method of returning the timing of the feeding service with dual backup storage controllers" With the proposal of this issue: 'can contribute to the public. The object of the present invention is to provide a method for timing error return of a server with a dual backup storage controller, which is applied to a server including a _ storage keeper and a second storage controller. Error return: (fail back) after the program 'automatically set the resources and services of the second storage controller not yet to the storage controller to be transferred to the project, = 200821860 = all, the transfer project is established - the transfer form, and Established - regular execution. And the interim execution program is __ fixed time interval, and each of the already transferred idle transfer items in the transfer table is transferred from the second storage controller to the first storage control ϋ 'and the turn wire (10) is in a busy state. The parent project _ is retained in the transfer order, and the fixed-line program of each system will be handed over to the first-storage controller, and the server will be deleted. In addition to the regular execution program, 値n can get the job. The purpose of automatically returning from the error is to solve the trouble of the traditional ship material to manually manage the manual fail program. For the purpose of understanding and understanding of the purpose, technical features and efficacy of the present invention, the present invention is described in detail with reference to the following: [Embodiment] The present invention is a The method for timing error return of the server of the dual backup storage controller is applied to a server, and the server includes a first storage control $1 and a second storage control H2. When the abnormal condition of the first storage control person 1 is excluded, and the server executes the error return (fdi back) program, first check each resource or service owner list of the server (such as a directory service, The current directory service active directory service, etc., is used to find 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 200821860). No), and the establishment period of the fixed-term execution period, that is, the attempt to transfer the 13-permitted procedure, every second interval, and the transfer of the second-to-one device 2 to the transfer project in Table 3, and the storage control H 1, bribe _ in addition to the local line material to the first reading system to the first reading system, please refer to (10)) to determine whether it has met the fixed difficulty program - fixed time (2Q2) = f), otherwise step _Read each transfer item 3(), and transfer each transfer item 30 from the second storage controller 2 to the first storage controller 1, and delete the transferred transfer item 30 from the transfer table 3. : or the transfer of the transferred item 30 that has not been transferred to continue in the parent table 3 and the server deletes or retains the transfer item 3〇, as shown in Figure 3, including: (10) from the wire 3 towels read their towels - when this regular execution of the private order was executed, still The processed handover item 3〇 (11) determines whether the currently transferred handover item (9) is in the idle state in the second storage controller 2, if the following step (12) is performed, otherwise step (15) is performed. (12) The currently read transfer item 30 is transferred from the second storage controller 2 to the first storage controller 1, and the currently read transfer item 30 is deleted from the transfer table 3, and then the following steps are performed in 200821860 ( 13); (10) judging whether all the transfer items 30 of the rotary wire 3 have been read, if the following step (14) is performed, otherwise the step (10) is performed; (Η) the periodic execution program has been processed, that is, the end (15) The currently read transfer item 3() is not in the idle state in the second storage controller 2, that is, the resource or service corresponding to the second storage controller 2 of the transfer item 30 is still busy. Keep the currently transferred transfer item 30' and proceed to step (1〇). (204) Judging that the Rope 3 towel is God's transfer item 3, if the following steps (201) are performed, otherwise the step (2〇5) is performed; (205) There is no transfer item in the Tianjiao parent table 3, Then delete the regular execution program, which is the end. For example, as shown in FIG. 4, the server includes a first storage control 21, a second storage controller 2, and a fourth storage unit (heart:: 7), wherein the first storage controller 1 Management of the first, second and fourth storage early (4, 5, 7) 'Material 2 storage controller 2 manages the third storage list =, and the server receives the first storage control through the second storage controller 2 The heartbeat signal is determined by the second storage controller 2 as to whether the segment is not connected (four) heartbeat. If the second storage is off for a period of time, the heartbeat signal is not received, indicating that the storage controller 1 has an abnormal condition. (As shown in Figure 5), immediately the storage controller 2 takes over all of the storage units (4, 5, 6, 7). 200821860 Please refer to Figure 6, when the abnormal condition of the first-storage controller is removed, the 'feeder performs an error return (fail bad〇 program, first, the storage controller 1 has taken over the first storage unit) 4, but the second and fourth storage units (5, 7) are in a busy state, therefore, the first storage controller has not yet taken over the first and fourth storage units (5, 7), and at this time, still the second storage The controller 2 manages the second and fourth storage units (5, 7), and the first storage controller 1 has not been able to take over the second and fourth storage units (5, 7) respectively set to one transfer item 30' and thus two Transfer project 3 〇 Establish transfer table 3 (as shown in Figure 1) 'Key _ _ regular execution procedures, so that the job is separated by a fixed period of time, that is, try to put the second and fourth storage units (5, 7) by The second storage controller 2 hands over to the first-storage controller until the regular execution process ^ the two-transfer item 30 has been handed over to the first-storage controller 1 (ie, restored to as shown in FIG. 1), the server is Delete the periodic execution procedure. / As can be seen from the above, the present invention establishes the transfer form 3 and executes the periodicity. The line program causes the server to automatically execute the periodic execution program, and transfers the transfer items 30 in the idle form 3 to the first storage controller. This will solve the problem of waiting for the resources and services from the busy record status. Turned into the job (four), show hands _ way will: New or service transfer, the shortcomings of the storage control 1 'avoid the manager's inconvenience in managing the feeding device. The specific features of the present invention are not limited thereto, and any variation or modification that can be easily conceived by those skilled in the art can be covered by the following patents. 200821860 [Simplified description of the drawings] Fig. 1 is a schematic diagram of the transfer table of the present invention; the first figure is a flow chart of the % action of the present invention; the figure 3 is the transfer item of the present invention η which has been transferred from the transfer form.
