Description

Technical Field

[0001] This application relates to the field of computer hard disks, and in particular to a method, apparatus, and medium for handling serial hard disk failures. Background Technology

[0002] SATA is an abbreviation for Serial ATA. It is a computer bus whose main function is to transmit data between the motherboard and a large number of storage devices (such as hard drives and optical disc drives). It is named for its serial data transmission method and also has the advantages of simple structure and support for hot-swapping.

[0003] SATA storage devices are widely used in hardware products such as servers. Since SATA is a communication interface that includes a communication protocol, ensuring the security and accuracy of stored information is paramount for SATA storage devices to function properly. Currently, when a serial ATA hard drive malfunctions, hardware maintenance personnel can only diagnose the problem by testing the electrical signals and analyzing the reliability of the physical link. However, besides physical link failures, software-level faults such as abnormal transmission protocols and unexpected serial port failures can also cause serial ATA hard drive failures.

[0004] Therefore, it is evident that providing a more comprehensive fault detection method to enable maintenance personnel to determine whether there are faults in the software transmission layer of serial hard drives is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] Once fault information is detected, the faulty hard drive is identified based on that information.

[0008] Obtain the status information of the faulty hard drive;

[0009] Determine whether the status information meets the preset conditions;

[0010] If the preset conditions are met, a command is sent to the DEVSLP pin of the faulty hard drive to control the link restart of the faulty hard drive.

[0022] Preferably, after the step of sending a command to the DEVSLP pin of the faulty hard disk, the method further includes:

[0023] After the link of the faulty hard drive is restarted, it is determined whether the fault information exists on the faulty hard drive;

[0024] If the aforementioned fault information exists, the fault information will be sent to maintenance personnel.

[0030] Furthermore, the serial hard drive fault handling device provided in this application also includes: a low-power state judgment module and a fault information sending module. The low-power state judgment module is used to send a test data packet to the faulty hard drive and obtain the time parameters of the faulty hard drive; it then determines whether the faulty hard drive has entered a low-power state based on the time parameters. The fault information sending module is used to determine whether the faulty hard drive has the fault information after the link of the faulty hard drive is restarted; if the fault information exists, it sends the fault information to maintenance personnel.

Thus, the serial hard drive fault handling scheme provided in this application, by sending a command to the DEVSLP pin of the faulty hard drive when preset conditions are met to put the device into a low-power state, thereby restarting the link between the faulty hard drive and the controller, determines whether there is a fault in the software transport layer of the faulty hard drive, facilitating maintenance personnel to maintain the faulty hard drive.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0043] The core of this application is to provide a method, device, and medium for handling serial hard drive failures, so as to determine whether there is a fault in the software transmission layer of the serial hard drive, so as to facilitate maintenance personnel to maintain the faulty hard drive.

[0044] For ease of understanding, the hardware architecture to which the technical solution of the present invention applies will be described below. Figure 1 The diagram illustrates a serial hard drive connection method provided in an embodiment of this application, as shown below. Figure 1As shown, the controller communicates with the serial ATA hard drive via the DEVSLP signal. The SATA bus uses an embedded clock frequency signal, providing stronger error correction capabilities than before. It can check transmission commands (not just data) and automatically correct errors, improving data transmission reliability. The most obvious difference between SATA and previous models is the use of thinner ribbon cables, which facilitates airflow within the chassis and increases the stability of the entire platform. Table 1 shows a typical SATA interface diagram. As shown in Table 1, the signal pins P1, P2, and P3 on the power side of the serial ATA hard drive are usually idle. For ordinary 2.5-inch and 3.5-inch HDDs and SSDs, these three pins are not usable. Pin 3 is used to transmit the DEVSLP signal, which puts the device into a low-power state. If the device briefly idles during read / write operations, the OS or motherboard may trigger the "DEVSLP" command. The controller sends this signal to put the device into a low-power state, thus initiating the data transmission link between the storage device and the controller. The technical solution provided in this application is applied to the controller of a smart device for SATA hard drive fault detection. In a specific implementation, the controller sends a command to the serial hard drive through the P3 pin of the serial hard drive to control the hard drive to enter a low-power state.

[0046]

[0047] In serial ATA hard drive (SATA) applications, ensuring normal data transmission requires a stable communication link. When a SATA hard drive malfunctions, hardware maintenance personnel can only test it by checking electrical signals and analyzing the reliability of the physical link. However, besides physical link failures, software-level faults such as abnormal transmission protocols or unexpected serial port failures can also cause SATA hard drive failures. To enable maintenance personnel to determine if there is a fault in the software transmission layer of a SATA hard drive, this application provides a SATA hard drive fault handling method. This method includes: upon detecting fault information, identifying the faulty hard drive based on the fault information for subsequent handling; acquiring the status information of the faulty hard drive and determining whether the status information meets preset conditions; if the preset conditions are met, sending a command to the DEVSLP pin of the faulty hard drive to control the link restart of the faulty hard drive. Therefore, the SATA hard drive fault handling method provided in this application, by sending a command to the DEVSLP pin of the faulty hard drive when preset conditions are met to put the device into a low-power state, thereby restarting the link between the faulty hard drive and the controller, determines whether there is a fault in the software transmission layer of the faulty hard drive, facilitating maintenance personnel to maintain the faulty hard drive.

[0048] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Figure 1 A serial port hard drive fault handling method provided in the embodiments of this application, such as Figure 1 As shown, the method includes:

[0050] S10: After detecting fault information, determine the faulty hard drive based on the fault information.

[0051] It should be noted that the technical solution provided in this application is applied to serial ATA hard drives to detect whether there are software transmission protocol level faults in the serial ATA hard drives. The technical solution provided in this application is applied to a device including a main controller and a serial ATA hard drive, wherein the control pin of the main controller is connected to the PIN3 pin of the serial ATA hard drive to send a DEVSLP signal to the serial ATA hard drive. Simultaneously, the DEVSLP signal receiving end on the device side controls whether the DEVSLP signal is set by pulling it high or low.

[0052] In practice, considering that there are usually multiple hard drives in a server, in order to improve the efficiency of fault diagnosis, the fault information sent by the control is obtained, and the drive letter, region and other information of the faulty hard drive are determined based on the fault information.

[0053] S11: Obtain the status information of the faulty hard drive;

[0054] S12: Determine whether the status information meets the preset conditions.

[0055] In practice, the status information of the faulty hard drive is first obtained, and it is determined whether the status information meets the preset conditions to determine whether the faulty hard drive can enter the low power mode.

[0056] The status information of a faulty hard drive can be obtained by reading SCR0 of the SATA Status Register. Specifically, the values ​​of bits [11:8] of this register are mapped to the Interface Power Management (IPM) module. Therefore, by setting the IPM module to read the value in this register, the controller (Host) can determine the state that the SATA hard drive (Device) is required to enter. If the controller determines that the SATA hard drive can successfully hit the DEVSLP signal by reading the value in the SATA Status Register, then the status information of the SATA hard drive is considered to meet the preset conditions.

[0057] S13: If the preset conditions are met, send a command to the DEVSLP pin of the faulty hard drive to control the link restart of the faulty hard drive.

[0058] In practical implementation, when the controller determines that the serial hard drive can successfully hit the DEVSLP signal by reading the value in the serial port status register, it sends a DEVSLP command to the PIN3 pin of the serial hard drive to put it into a low-power state. This restarts the communication link between the serial hard drive and the controller. The simulated link initialization is equivalent to simulating the process of the communication link going from a power-off state to a power-on state. In this embodiment, when the serial hard drive malfunctions, we can force the device into the DEVSLP low-power state by enabling the DEVSLP signal. Once in this state, operating the device or re-enabling the signal will break the low-power state, requiring a re-link initialization to identify the device and re-read and identify it.

[0059] This embodiment provides a serial hard drive fault handling method, including: upon detecting fault information, identifying the faulty hard drive based on the fault information to facilitate subsequent processing; acquiring the status information of the faulty hard drive and determining whether the status information meets preset conditions; if the preset conditions are met, sending a command to the DEVSLP pin of the faulty hard drive to control the link restart of the faulty hard drive. Therefore, the serial hard drive fault handling method provided in this application, by sending a command to the DEVSLP pin of the faulty hard drive when preset conditions are met to put the device into a low-power state, thereby restarting the link between the faulty hard drive and the controller, determines whether there is a fault in the software transport layer of the faulty hard drive, facilitating maintenance personnel to maintain the faulty hard drive.

[0060] In a preferred embodiment, obtaining the status information of the faulty hard drive includes: reading the serial port status register to obtain the status information. The status information includes at least: normal operating status, link initialization status, and low power consumption status; correspondingly, the preset condition is that the status information is in the normal operating status.

[0061] In practical implementation, the host controller can obtain the status information of the faulty hard drive by reading SCR0 of the SATA Status Register. The values ​​of bits [11:8] of this register are mapped to the Interface Power Management (IPM) module. Therefore, by setting the IPM module to read the value in this register, the host can determine the state the controller (Host) requires the SATA hard drive (Device) to enter. The SATA hard drive's states include normal operation, link initialization, and low power. The low power state is when the SATA hard drive stops working, and the link initialization state is the link recovery phase. When in the link initialization state, the controller can re-enable the SATA hard drive, thereby re-establishing the communication link between the SATA hard drive and the controller to resolve software-level faults such as transmission protocol anomalies and unexpected serial port failures.

[0062] In practical implementation, when the main controller determines that the faulty hard drive can hit the DEVSLP pin, it sends a command to the faulty hard drive to put it into a low-power state. Sending the command to the DEVSLP pin includes sending a standby immediate command to the DEVSLP pin to put the faulty hard drive into a low-power state. Therefore, the serial hard drive fault handling method provided in this application, by sending a command to the DEVSLP pin of the faulty hard drive to put the device into a low-power state when preset conditions are met, restarts the link between the faulty hard drive and the controller, thereby determining whether there is a fault in the software transport layer of the faulty hard drive, facilitating maintenance personnel to maintain the faulty hard drive.

[0063] Understandably, if the controller sends a command to the DEVSLP pin of the faulty hard drive, and data transmission still fails after the link to the faulty hard drive restarts, it indicates a hardware-level fault in the hard drive. However, due to the special nature of the DEVSLP pin, the command sent by the controller may not always be successful. Therefore, it is necessary to test the faulty hard drive to determine if it has entered a low-power state.

[0064] Based on the above embodiment, after the step of sending an instruction to the DEVSLP pin of the faulty hard disk, the method further includes: sending a test data packet to the faulty hard disk and obtaining the time parameters of the faulty hard disk; and determining whether the faulty hard disk has entered a low-power state based on the time parameters.

[0065] Understandably, if the faulty hard drive does not enter a low-power state, the controller will send a standby immediate command to the DEVSLP pin again to bring the faulty hard drive into a low-power state.

[0066] It is important to note that the causes of hard drive failures include not only software-level faults such as transmission protocol anomalies and unexpected serial port failures, but also physical link failures. Restarting the transmission link of a faulty hard drive only addresses software-level faults. Therefore, in a preferred embodiment, after sending a command to the DEVSLP pin of the faulty hard drive, the process further includes: after restarting the link of the faulty hard drive, determining whether fault information exists; if fault information exists, sending the fault information to maintenance personnel. This allows administrators to promptly maintain the physical connection of the faulty hard drive.

[0067] The serial port hard drive failure handling method has been described in detail in the above embodiments. This application also provides embodiments corresponding to the serial port hard drive failure handling device. It should be noted that this application describes the device embodiments from two perspectives: one is based on functional modules, and the other is based on hardware.

[0068] Figure 3 This is a structural diagram of a serial hard disk fault handling device provided in an embodiment of this application, as shown below. Figure 3 As shown, the serial hard disk fault handling device provided in this application includes:

[0069] The determination module 10 is used to determine the faulty hard drive based on the fault information after the fault information is detected.

[0070] Module 11 is used to acquire the status information of the faulty hard drive;

[0071] Judgment module 12 is used to determine whether the status information meets the preset conditions;

[0072] The instruction sending module 13 is used to send an instruction to the DEVSLP pin of the faulty hard disk if preset conditions are met, so as to control the link restart of the faulty hard disk.

[0073] In practice, the status information of the faulty hard drive is first obtained, and it is determined whether the status information meets the preset conditions to determine whether the faulty hard drive can enter the low power mode.

[0074] The status information of a faulty hard drive can be obtained by reading SCR0 of the SATA Status Register. Specifically, the values ​​of bits [11:8] of this register are mapped to the Interface Power Management (IPM) module. Therefore, by setting the IPM module to read the value in this register, the controller (Host) can determine the state that the SATA hard drive (Device) is required to enter. If the controller determines that the SATA hard drive can successfully hit the DEVSLP signal by reading the value in the SATA Status Register, then the status information of the SATA hard drive is considered to meet the preset conditions.

[0075] In practical implementation, when the controller determines that the serial hard drive can successfully hit the DEVSLP signal by reading the value in the serial port status register, it sends a DEVSLP command to the PIN3 pin of the serial hard drive to put it into a low-power state. This restarts the communication link between the serial hard drive and the controller. The simulated link initialization is equivalent to simulating the process of the communication link going from a power-off state to a power-on state. In this embodiment, when the serial hard drive malfunctions, we can force the device into the DEVSLP low-power state by enabling the DEVSLP signal. Once in this state, operating the device or re-enabling the signal will break the low-power state, requiring a re-link initialization to identify the device and re-read and identify it.

[0077] Furthermore, the serial hard drive fault handling device provided in this application also includes: a low-power state judgment module and a fault information sending module. The low-power state judgment module is used to send a test data packet to the faulty hard drive and obtain the time parameters of the faulty hard drive; it then determines whether the faulty hard drive has entered a low-power state based on the time parameters. The fault information sending module is used to determine whether the faulty hard drive has the fault information after the link of the faulty hard drive is restarted; if the fault information exists, it sends the fault information to maintenance personnel.

[0078] This application provides a serial hard drive fault handling method, including: upon detecting fault information, identifying the faulty hard drive based on the fault information to facilitate subsequent processing; acquiring the status information of the faulty hard drive and determining whether the status information meets preset conditions; if the preset conditions are met, sending a command to the DEVSLP pin of the faulty hard drive to control the link restart of the faulty hard drive. Therefore, the serial hard drive fault handling method provided in this application, by sending a command to the DEVSLP pin of the faulty hard drive when preset conditions are met to put the device into a low-power state, thereby restarting the link between the faulty hard drive and the controller, determines whether there is a fault in the software transport layer of the faulty hard drive, facilitating maintenance personnel to maintain the faulty hard drive.
