[0002] With the rise of artificial intelligence generated content (AIGC) and intelligent computing centers, the requirements for data center network equipment are getting higher and higher. When the current mainstream network equipment is running for a long time, there is a high probability that the solid state drive (SSD) will fail, such as becoming read-only, making the system unable to work properly. When an abnormality occurs, the SMART properties of the SSD hard disk are queried, and no abnormality is reported.

[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0045] In an exemplary embodiment, Figure 1 As shown, a method for repairing SSD faults is provided, and the method is applied to network devices such as switches as an example for explanation. It is understandable that the method can also be applied to other devices equipped with SSDs, such as servers, more specifically, such as independent physical servers, or server clusters or distributed systems composed of multiple physical servers, or cloud servers that provide cloud computing services; it can also be applied to terminals, such as various personal computers, laptops, IoT devices, etc. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, gaming devices, etc. In this embodiment, the method includes the following steps S202 to S206. Among them:
[0046] S202, when an SSD failure is detected, calling a preset reset function to reset.
[0047] Among them, the preset reset function is a function used for device hard disk error processing and repair, and is generally stored in the device storage system. During the data transmission process, if the SSD has a communication error or a read-write error due to power fluctuations or other interference, such as changing from a read-write state to a read-only state, the switch system can call the preset reset function to perform a reset process to solve the fault problem. For SSDs with SATA (Serial Advanced Technology Attachment) interfaces, the preset reset functions are ata_do_reset and other functions; for SSDs with other interface types, such as PCIe interfaces, the commonly used reset functions under the corresponding interface types can also be used, and examples are not given one by one here.
[0048] For example, for an SSD with a SATA interface, when an SSD failure is detected in the current Linux kernel, the SATA driver of the switch may call ata_do_reset to perform a reset (comreset).
[0049] S204: If the reset is unsuccessful, determine whether the number of reset retries reaches a preset threshold.
[0050] Specifically, if the switch fails to reset by calling the preset reset function, it is necessary to further determine whether the number of reset retries reaches the preset threshold. The number of reset retries refers to the number of times the preset reset function is called. The system sets an upper limit for the number of reset retries, which is the preset threshold. For example, it can be 3, 4 or 5 times. The preset threshold can be selected according to actual needs.
[0051] S206: If the number of reset retries reaches a preset threshold, the faulty SSD is powered on and off and reset.
[0052] In traditional technology, if the switch calls the preset reset function and the number of reset retries reaches the preset threshold, it will generally feedback the repair failure result and exit the fault repair process. At this time, if you want to continue to complete the SSD fault repair, you need to power off and restart the entire machine. The power off and restart operation of the entire machine needs to interrupt the task currently being executed by the device, affecting business continuity.
[0053] In this embodiment, taking the preset threshold of 3 times as an example, the switch determines that the reset retry times reach 3 times, that is, after the reset fails after the third call of the preset reset function, the faulty SSD is individually powered on and off. The SSD has a separate power supply pin, so the switch can perform power-on and power-off reset logic on the SSD alone without powering off and restarting the whole machine, so as to realize the independent restart of the faulty SSD, thereby clearing the previous error state, such as the read-only state.
[0054] The above SSD fault repair method, when an SSD fault is detected, calls the preset reset function for reset; if the reset is unsuccessful, determines whether the number of reset retries reaches the preset threshold; if the number of reset retries reaches the preset threshold, the SSD is powered on and off and reset. By adding a separate power-on and power-off processing process for the SSD hard disk to the repair process, when an SSD fault occurs, the system can perform a separate power-on and power-off repair on the SSD hard disk without restarting the entire machine or interrupting the currently executing task, thus ensuring the continuity of the data processing task. And without the need for operation and maintenance intervention, the system automatically completes the SSD fault repair, which is more efficient.
[0055] In an exemplary embodiment, Figure 2 As shown, before S202, it also includes:
[0056] S201, registering a hook function in the system kernel, wherein the hook function is used to instruct the BSP to execute SSD power-on and power-off logic.
[0057] It can be understood that the switch registers the hook function into the system kernel when the BSP (i.e., board support package) is initialized, and when an SSD failure occurs, the system kernel can be triggered to automatically call the hook function to instruct the BSP to execute the SSD power-on and power-off logic.
[0058] Example of registering hook function interface code:
[0059]
[0060]
[0061] S206 includes:
[0062] S302, if the number of reset retries reaches a preset threshold, obtain the above hook function;
[0063] S304, calling the BSP according to the hook function to power on and off the faulty SSD and reset it.
[0064] When an SSD failure occurs, the switch system kernel can be triggered to automatically call the hook function. Exemplarily, the system kernel first obtains the previously registered hook function, and then calls the BSP to power on and off the SSD according to the hook function. For example, the BSP configures the CPLD (complex programmable logic device) to power on and off the SSD.
[0065] Code example of calling the hook function in the system kernel:
[0066]
[0067]
[0068] In this embodiment, by registering a hook function for instructing BSP to execute SSD power-on and power-off logic into the system kernel, the system can automatically call the hook function to respond when the trigger condition is met, thereby automatically completing SSD fault repair in an efficient and timely manner.
[0069] In an exemplary embodiment, Figure 3 As shown, after the faulty SSD is powered on and off and reset, the following steps are also included:
[0070] S208, recording the power-on and power-off reset actions in the log, and returning to the step of calling the preset reset function to perform the reset.
[0071] Specifically, after the switch performs power-on and power-off reset on the SSD, the switch records the power-on and power-off reset action on the SSD in the system log. Whether the reset is successful or failed, it is recorded in the system log for operation and maintenance personnel to view and use.
[0072] After the switch records the power-on and power-off reset actions in the log, it needs to return to the step of calling the preset reset function to reset again, and cyclically execute the SSD fault repair process until the feedback result of repair success or repair failure is obtained and the reset logic is exited.
[0073] In this embodiment, by recording the power-on and power-off reset actions in the log, it is convenient for operation and maintenance personnel to view and use the system log, so as to provide a basis for operation and maintenance work or optimization of the SSD fault repair process.
[0074] In one embodiment, if Figure 4 As shown, the above SSD fault repair method also includes:
[0075] S402: If the reset is successful, determine whether a port connection is established.
[0076] Specifically, if the switch successfully resets by calling the preset reset function, it further determines whether to establish a port connection, wherein the port includes both the port on the upper chip side connected to the SSD, such as the CPU side port, and the SSD side port.
[0077] S404: If yes, record in the log that the fault is repaired successfully.
[0078] The switch calls the preset reset function to reset successfully, and determines that the port between the SSD and the upper chip has established a connection, indicating that the SSD fault is repaired successfully, and the fault repair success is recorded in the system log. It can also feedback the result of the successful SSD fault repair, exit the fault repair logic, and the process ends.
[0079] S406: If the port connection is not established and the number of reset retries is greater than a preset threshold, a fault repair failure is recorded in a log.
[0080] Specifically, the switch calls the preset reset function to reset successfully, but determines that the port between the SSD and the upper chip is still not connected. At this time, the SSD fault still exists and the SSD cannot be used normally. If the number of reset retries is greater than the preset threshold, it means that the SSD fault repair has failed, and the fault repair failure is recorded in the system log. The result of the SSD fault repair failure can also be fed back, and the fault repair logic is exited, and the process ends.
[0081] The inventor found in actual research that during the SSD fault repair process, sometimes even if the system calls the preset reset function to reset successfully, the SSD still cannot be used normally. The cause is often found to be due to a problem with the port connection between the SSD and the upper chip. However, in the traditional technology, the port status is generally not automatically detected when repairing the SSD fault, which reduces the efficiency of SSD fault repair. In this embodiment, when the switch calls the preset reset function to reset successfully, a port connection status detection process is further added and recorded in the system log, so that even if the SSD fault repair fails, it is easy to find the cause in time, which is conducive to improving the efficiency of SSD fault repair.
[0082] In an exemplary embodiment, Figure 5 As shown, the above SSD fault repair method also includes:
[0083] S502: If the number of reset retries is less than a preset threshold, determine whether the SSD response has timed out.
[0084] For example, when the switch calls the preset reset function and the number of reset retries is less than the preset threshold, it does not need to start the process of powering on and off the SSD, but enters the process of determining whether the SSD response has timed out. SSD response timeout may be caused by a large amount of CPU and memory resources being occupied, excessive load, or driver compatibility issues or even hardware connection issues.
[0085] S504: If yes, the interface data traffic between the CPU and the SSD is slowed down.
[0086] For example, the interface data flow can be decelerated by adjusting the speed mode of the interface between the CPU and the SSD from a high speed mode to a lower speed mode. For example, a SATA interface SSD can be adjusted from a SATA 3.0 mode to a SATA 2.0 or SATA 1.0 mode.
[0087] S506: If not, return to the step of calling the preset reset function to reset.
[0088] In this embodiment, if the number of reset retries is less than a preset threshold, it is further determined whether the SSD response has timed out, and in the case of a response timeout, the interface data traffic between the CPU and the SSD is slowed down. This can reduce compatibility issues or SSD failures caused by high loads to a certain extent, making it easier to eliminate SSD failures as soon as possible without necessarily powering on and off the SSD to reset it, further reducing the impact on business continuity.
[0089] In an exemplary embodiment, see Figure 5 After the data flow of the interface between the CPU and the SSD is slowed down, the method further includes:
[0090] S508, recording the speed reduction processing action in the log, and returning to the step of calling the preset reset function to reset.
[0091] In this embodiment, after the speed reduction process is performed on the interface between the CPU and the SSD, the speed reduction process action is further recorded in the system log so that the operation and maintenance personnel can view and use it.
[0092] In a specific embodiment, Figure 6 As shown, a method for repairing an SSD fault is provided, comprising the following steps:
[0093] S1, detects whether the SSD is faulty, if so, enters S2;
[0094] S2, call the preset reset function to reset;
[0095] S3, determine whether the reset is successful, if not, go to S4, if yes, go to S11;
[0096] S4, determine whether the number of reset retries is greater than the threshold, if not, enter S5, if yes, enter S13
[0097] S5, determine whether the number of reset retries reaches the threshold, if yes, go to S6, if no, go to S8;
[0098] S6, power on and off the SSD to reset;
[0099] S7, record the power-on and power-off reset actions in the log, and return to S2;
[0100] S8, determine whether the SSD response timeout; if so, enter S9, if not, return to S2;
[0101] S9, reducing the speed of the interface data traffic between the CPU and the SSD;
[0102] S10, record the speed reduction process in the log, and return to S2;
[0103] S11, determine whether the port connection is established; if so, enter S12, if not, return to S4;
[0104] S12, record the failure repair success in the log, and exit the failure repair process;
[0105] S13, record the failure of fault repair in the log, and exit the fault repair process.
[0106] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows.
