[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, any other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0046] The core of the present application is to provide a network device fault repair method, system, electronic device and medium, mainly related to the network device related technical field, mainly applied in a multi-controller network, for solving the problem that when any network device in the network fails, it will not cause the state change of other network devices connected with the network device, avoiding the alarm and other operations of the other network devices, realizing the alarm shielding of the other network devices, and guaranteeing the network communication ability of the other network devices.

[0047] In order to enable those skilled in the art to better understand the present application scheme, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0048] In the technical field of servers, the storage server hardware design often adopts a multi-controller redundancy mode to ensure data reliability and security. In the latest multi-controller interconnection technology of storage servers, network interconnection is often the preferred option. Different controllers interact and access management data through network interconnection, but due to the reliability design requirements of storage servers, there is a risk of failure of the entire network interconnection network hardware device. The baseboard management controller is the core of server hardware management, and providing reliable and stable network repair capability is an important reliability means for the entire network architecture of the storage server

[0049] Therefore, based on a storage server full network interconnection architecture, Figure 1 A connection diagram of a controller in a multi-controller server is provided. Figure 1The server frame shown in the figure contains a plurality of controllers 1, each of which is redundant backup for the other controllers 1, wherein the controller 1 includes a central processing unit (CPU), a baseboard management controller (BMC) 2 and a complex programmable logic device (CPLD) 3; wherein the CPLD 3 between different controllers 1 is connected through a backplane 4; wherein the backplane 4 is equivalent to a line in the server. Figure 2 A schematic diagram of network interconnection between network devices in a multi-control server is provided; as Figure 2 shown, wherein each controller 1 further includes a data exchange chip (GE) 5 in addition to the devices mentioned above. Wherein the BMC 2 and the CPU are connected with the GE 5 through different ports, and exchange data within the controller 1 through different ports of the GE 5; wherein two multi-control shared management boards 6 devices are also provided; wherein the management board 6 is also provided with a GE 5, and is also provided with a physical layer chip (PHY) 7 and other network devices; wherein the CPU in the above-mentioned controller 1 exchanges data with the management board 6 through the PHY 7, and exchanges data with the GE 5 through a normal network port; the GE 5 on the management board 6 and the GE 5 in the controller 1 are interconnected to form a hardware structure for network interconnection and intercommunication between different controllers 1 in the storage server.

[0050] Based on the above hardware structure, after the server is powered on, the network communication of the controller 1 and the management board 6 is monitored by the BMC 2, when the GE 5 in the controller 1 and the GE 5 on any management board 6 fail, the repair process of the BMC 2 is triggered, in the original way, repairing any GE 5 in the multi-control network interconnection and intercommunication will cause the network state of other related devices to change; in order to solve the above problem, that is, to ensure that the process of repairing the network device will not affect the network communication capability of other controllers 1, and to reduce the possibility of fault propagation, the present application provides a network device fault repair method, Figure 3 A flowchart of a network device fault repair method is provided, as Figure 3 shown, the method specifically includes:

[0051] S10: Obtain the state information of the network device.

[0052] Wherein the network device can be a controller, or a management board connected to the controller; wherein the state information of the network device includes: the fault state of the network device, that is, whether the network device is in a fault state or a normal operating state; and the connection state of the related service port of the network device, wherein the service port is mainly the related port of the GE in the network device, the GE has ports of different links, and is interconnected with different network devices, and the state (LinkDown and LinkUp) of the port is judged by the BMC to determine whether the network communication state is normal.

[0053] The state information can be acquired in real time, or the acquisition frequency can be set, and the state information of the network device can be acquired at a fixed time, and the acquired state information can be stored in a related memory for subsequent use.

[0054] S11: determining whether the corresponding network device has a fault according to the state information.

[0055] In the above step, the state information of the network device is acquired, and in this step, it is determined whether the corresponding network device has a fault according to the related state information. For example, the state of a controller changes from normal to fault, or the port of a GE in the controller changes from LinkUp to LinkDown. The BMC can monitor the state of the network device by setting a network device monitoring module. When the BMC cannot access the network device or detects that the state of the network device is abnormal, subsequent steps such as repairing the network device are needed.

[0056] S12: If the network device has a fault, acquiring other network devices connected to the network device.

[0057] As shown in the above Figure 1 and Figure 2 , the network device and the other network devices have a connection relationship, that is, the controllers are connected through a backplane, and the controller and the management board are connected through the port of the GE. Therefore, when a network device has a fault, the other network devices connected to the network device are first determined, and the other network devices are controlled in the subsequent steps, so that the influence of the faulty network device on the other network devices can be avoided.

[0058] S13: repairing the network device and controlling the state of the other network devices to realize alarm shielding.

[0059] There are various repair methods, and the commonly used methods include a repair method of pin reset of the network device, which mainly triggers a reset action of the hardware reset pin of the network device, and after the hardware reset is completed, the state information of the network device is read again to determine whether the fault is solved. Another method is a repair method of power-on reset of the network device, which specifically sends a power-on reset instruction to the CPLD in the controller through the BMC of the controller, and performs power-on reset operation on the network device through the CPLD. If the InitDone signal of the network device is set, it proves that the power-on reset is successful. The BMC reads the state information again to determine whether the fault is repaired. The above two repair methods are independent of each other, but only one method can be used to repair the fault at a time. The reset method is relatively fast, about 1s, and the power-on reset method is equivalent to restarting the device, which takes a long time.

[0060] The state of the network device can be divided into an alarm state in normal operation, that is, if a relevant fault is detected when the device is running, the alarm information is reported in time, and the device changes from normal operation to standby operation, and when the fault is handled, the device runs again. The repair state in normal operation is also set, that is, after the device detects a relevant fault, no alarm information is reported, and the device continues to run normally. Therefore, when repairing a network device, to avoid causing other network devices to also report alarm information, other network devices need to change from the alarm state to the repair state, so that no alarm information is reported and the running is not stopped, thereby ensuring the network communication capability of the device.

[0061] The network device fault repair method provided in the embodiment can realize alarm shielding of other network devices connected to the network device when repairing the fault of the network device in a network with multiple controllers, avoid causing the fault of the related network devices when the network device fails, ensure the network communication capability of the other network devices, and improve the user experience.

[0062] On the basis of the above embodiment, the state of the other network device is limited to be controlled to realize the alarm, including changing the state of the register in the other network device from the alarm state to the repair state to realize the alarm shielding.

[0063] The register can store specific state information, and the state information is specifically stored by specific data. When the data changes, the corresponding state information of the register also changes.

[0064] The network device includes a CPLD, and the register is arranged in the CPLD. Figure 1 It can be known that the CPLD in the controller is connected through the backboard, so when a certain controller changes from the alarm state to the repair state, the CPLD between the controllers realizes the state synchronization of the register through the backboard, so that the register of the other controller also changes from the alarm state to the repair state.

[0065] The embodiment provides a method for specifically controlling the state of the other network device, which can accurately and effectively control the other network device, avoid the influence of the faulty device, and maintain normal work.

[0066] On the basis of the above embodiment, the network device includes a controller and a management board. Correspondingly, if the network device is the controller, the other network devices connected to the network device include the other controllers connected to the controller. If the network device is the management board, the other network devices connected to the network device include all the controllers connected to the management board.

[0067] The register can store specific state information, and the state information is specifically stored by specific data. When the data changes, the corresponding state information of the register also changes. Figure 2It can be seen that when the controller fails, the management board connected thereto is not affected, and when the controller fails, other controllers connected thereto through the CPLD are generally not affected, but if the controllers are in information interaction, they may be affected, so as to avoid the above-mentioned situation, when the controller fails, other controllers connected thereto are also acquired. When a management board fails, it can be thought that the management board is reset and restarted for repair, and the GE of the management board causes the ports of all controllers connected to the management board to have a Link Down error, so the management board acquires all controllers connected thereto.

[0068] The embodiment defines which other network devices are connected to a specific network device, and guarantees the accuracy of the alarm shielding range.

[0069] On the basis of the above-mentioned embodiment, if the controller fails, the network device is repaired, and the state of the other network device is controlled to realize alarm shielding, which includes repairing the controller and controlling the state of the other controller to realize alarm shielding; if the management board fails, the network device is repaired, and the state of the other network device is controlled to realize alarm shielding, which includes acquiring the main controller corresponding to the management board from all controllers; repairing the management board through the main controller, and controlling the state of all controllers to realize alarm shielding.

[0070] When a network device fails, it needs to be repaired by the BMC. According to the above-mentioned embodiment, other network devices connected to the failed network device are as follows: when the controller fails, the BMC in the controller is used to repair the controller, and the register state of the CPLD in the controller is changed to synchronize the register state of the other network devices, thereby realizing alarm shielding; when the management board fails, no corresponding BMC is set in the management board, so a controller is needed to repair the management board. In theory, the management board can select any controller connected thereto to repair the management board, but in order to facilitate control, the embodiment limits that the management board has a corresponding main controller. When the management board fails, the BMC of the main controller is used to repair the management board, and the register state of the CPLD of the main controller is changed to synchronize the state of the other controllers, thereby realizing alarm shielding.

[0071] The embodiment limits how to repair the network device when the network device of different types fails, and how to realize alarm shielding for other network devices connected thereto. The state of the other network devices can be quickly and accurately controlled to realize alarm shielding.

[0072] On the basis of the above-mentioned embodiment, repairing the network device includes repairing the network device by means of pin reset.

[0073] Among them, the pin reset mode mentioned in the above embodiment is a way that can quickly repair the network device, and through this way, when repairing the controller, it will not affect the state of other controllers connected with the controller, effectively solving the problem of program running away in the controller, and here the specific way of pin reset is not limited, which can be manually reset by the staff, and other types of reset mode are not limited here.

[0074] The embodiment defines a way to repair the network device, which can quickly repair the fault of the network device.

[0075] As a preferred embodiment, the embodiment defines that if the network device still fails after the above repair method, the network device is repaired by the pin reset mode, and then the network device is repaired by the power-on reset mode.

[0076] Among them, the power-on reset is equivalent to re-equipment, which can effectively solve the problem of program running away in the controller, data error in the register and other problems; but the power-on reset is longer than the above-mentioned pin reset, and the equipment will stop working, affecting the work efficiency, but when the above-mentioned pin reset cannot solve the fault, it is necessary to use the power-on reset. If the above method still cannot repair the faulty network device, other repair methods can be used to continue to repair.

[0077] The embodiment defines that the two reset modes are used to repair the faulty network device, which can effectively repair the fault, and first through the pin reset with short time, then through the power-on reset, which can limit the efficiency of repairing the fault.

[0078] On the basis of the above embodiment, it is defined that in addition to the above steps, it also includes: counting the number of network device failures; if the number of network device failures reaches the preset number within the preset time, the network device is alarmed and reported.

[0079] The embodiment considers that if the network device does not report the alarm, the network device may fail after receiving the repair, but still fails soon. At this time, it needs to be considered whether the hardware of the network device is damaged, and the staff needs to check and repair. Therefore, when the network device fails, the failure of the network device needs to be counted, and whether the failure times of the network device reach the preset times within the preset time is judged; effectively preventing a network device from still being wrong after being repaired, avoiding the damage of the related hardware facilities of the network device. In the embodiment, the preset time and the preset times are not limited. If there is only one pin reset mode for repair, because the repair speed is fast, the preset time may be shorter, the times are more, if it is a power-on reset mode, the preset time may be set longer; here the specific can be judged according to the experience of the staff or the setting of the manufacturer or the historical data of the hardware equipment, etc., which is not specifically described here.

[0080] The embodiment limits the need to report the alarm, avoids repeated errors of the network device, and cannot be solved by repair, which needs the staff to check and avoid causing the system to be paralyzed and other problems.

[0081] The application also provides an embodiment of a network device failure repair method in a specific application scenario, in which the network device failure repair method is specifically as shown in Figure 4 The embodiment provides a network device failure repair method in a specific application scenario, which specifically includes the following steps: S20: monitoring state information of a network device; S21: if the state information shows that the network device fails, acquiring other network devices connected with the network device; S22: controlling states of the other network devices by CPLD to realize alarm shielding; S23: repairing the failed network device by a pin reset mode; S24: judging whether the failed network device is repaired successfully; if not, entering S25: repairing the still failed network device by a power-on reset mode; if yes, entering S26: completing network device failure repair; S27: counting failure times of the network device; and S28: if the failure times of the network device reach preset times within a preset time, reporting an alarm of the network device.

[0082] In the embodiment, the default repair mode of power-on reset can complete the repair of the network device. In the step S22, the state of the network device is controlled by the CPLD, specifically by controlling the state of the CPLD control register to control the state of the network device. The step S28 in the embodiment corresponds to the above embodiment, which is not described here.

[0083] The embodiment provides a network device failure repair method in a specific application scenario, which specifically includes the following steps: S20: monitoring state information of a network device; S21: if the state information shows that the network device fails, acquiring other network devices connected with the network device; S22: controlling states of the other network devices by CPLD to realize alarm shielding; S23: repairing the failed network device by a pin reset mode; S24: judging whether the failed network device is repaired successfully; if not, entering S25: repairing the still failed network device by a power-on reset mode; if yes, entering S26: completing network device failure repair; S27: counting failure times of the network device; and S28: if the failure times of the network device reach preset times within a preset time, reporting an alarm of the network device.
