Description

Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a hard disk exception processing method, device, equipment and computer-readable storage medium. Background Art

[0002] With the increase in business volume, in order to store large amounts of data in server systems, more and more hard disks are used, requiring higher and higher stability of hard disks.

[0003] In the use of hard disks in servers, the method of connecting hard disks with disk arrays (Redundant Array of Independent Disks, RAID) cards is currently a widely used method. Disk array cards can form different disk arrays. When a faulty disk appears in the disk array group, the data can be restored through the data reconstruction function of the disk array card. There are two situations for data recovery: the first situation is when the SAS (Serial Attached SCSI) link is abnormal. In the case of uncertainty whether the hard disk failure or the link failure occurs, the disk array card performs a diagnosis. If the diagnosis passes, the hard disk will be put back online for data reconstruction and recovery; the other situation is that the hard disk does fail, the disk array card removes the faulty hard disk, and after the next replacement, the disk array card performs data reconstruction and recovery on the new disk. In the first situation, if the hard disk reports an error again during the reconstruction process, the disk array card performs a diagnosis again. If the diagnosis passes, the hard disk will be put back online for data reconstruction and recovery. As a result, the hard disk is repeatedly online and offline, affecting the customer's system performance, and seriously causing system downtime.

[0004] In summary, how to effectively solve the problem of repeated data reconstruction and recovery of the hard disk, which causes the hard disk to be repeatedly online and offline, affects the customer's system performance, and seriously causes system downtime, is an issue that technical personnel in this field urgently need to solve.

[0064] The following are marked in the accompanying drawings:

[0065] 1-disk array card, 2-complex programmable logic device, 3-baseboard management controller, 4-power protection circuit. DETAILED DESCRIPTION

[0066] See Figure 1, which is a flow chart of a normal hard disk initialization power-on process. Normal hard disk power-on process: Press the power button (power button) to power on the server. After the system P12V power-on is completed, it will send a power good signal (PGOOD) to the complex programmable logic device (Complex Programmable Logic Device, CPLD). After receiving the signal, the complex programmable logic device sends an enable signal for the hard disk 12V power supply (P12V_HDD) and the hard disk 5V power supply (P5V_HDD) according to the power-on timing sequence designed by the system. The P12V and P5V power modules output P12V and P5V to the hard disk respectively, and the hard disk initialization power-on can work normally.

[0067] Refer to Figure 2, which is a processing logic diagram of a hard disk failure in the related art. When there is a faulty hard disk, the faulty hard disk reports an exception to the disk array card, and the disk array card transmits the hard disk status information to the complex programmable logic device. The complex programmable logic device parses the hard disk status information, sets the error flag bit to a high or low signal position, and sets the reconstruction flag bit to a low signal enable flag bit. When it is determined that the hard disk has indeed failed, the disk array card removes the faulty hard disk; when the disk array card detects the reconstruction enable signal, data reconstruction and recovery are performed. According to the reconstruction result, the corresponding identifiers in the reconstruction, remapping abort, completion, and hard disk drive failure information are transmitted to the baseboard management controller (Baseboard Management Controller, BMC) through the serial communication bus (Inter-Integrated Circuit, I2C) signal, and the baseboard management controller records the reconstruction result in the log.

[0068] See Figure 3, which is a block diagram of a hardware circuit design in the related art. The disk array card monitors the hard disk through the serial attached storage (SAS), and the disk array card transmits the hard disk status information to the complex programmable logic device. The complex programmable logic device transmits the corresponding identification of the drive failure or reconstruction, completion, and hard disk drive failure information to the baseboard management controller through the serial communication bus signal. When the complex programmable logic device detects a hard disk abnormality, it pulls the error signal low and lights up the hard disk error indicator.

[0069] See Figure 4, which is a hard disk status monitoring logic diagram in the related art. When there is a faulty hard disk, the faulty hard disk reports an exception to the disk array card, the disk array card transmits the hard disk status information to the complex programmable logic device, the complex programmable logic device parses the hard disk status information, and sets the reconstruction flag. When the disk array card detects the reconstruction enable signal, data reconstruction and recovery are performed. When the complex programmable logic device determines that the data reconstruction and recovery are successful, it transmits the hard disk drive reconstruction completion information to the baseboard management controller through the serial communication bus signal, and the baseboard management controller records the reconstruction completion information in the log.

[0070] In the use of hard disks in servers, there are serial ATA (SATA Advanced Technology Attachment, SATA) disks that are directly connected to the peripheral component interconnect host controller (PCH), which are relatively rare, and the speed can only reach 6Gb / s, and the performance is not high; there are also disk array cards / serial attached SCSI (SAS) cards that convert SAS signals through PCIE (Peripheral Component Interconnect Express, Peripheral Component Interconnect Extension Bus) signals, which can connect SAS disks and SATA disks. The speed of SAS disks can reach 12Gb / s. This method of using raid cards to connect hard disks is currently a widely used method. Raid cards have many functions, one of which is that they can form different disk arrays, such as RAID1, 5, 6, 10, etc. Different disk arrays are used in different scenarios, have different hard disk utilization rates, and have different effects on system read and write performance. However, these four types of disk arrays have data redundancy and fault tolerance. When a failed disk appears in the disk array group, the data can be restored through the data reconstruction function of the disk array card.

[0071] There are two situations for data recovery: the first situation is when the SAS (Serial Attached SCSI) link is abnormal, and it is uncertain whether the hard disk is faulty or the link is abnormal, the disk array card performs a diagnosis, and if the diagnosis is successful, the hard disk will be put back online for data reconstruction and recovery; the other situation is that the hard disk is indeed faulty, and the disk array card removes the faulty hard disk, and after the next replacement, the disk array card performs data reconstruction and recovery on the new disk. In the first situation, if the hard disk reports an error again during the reconstruction process, the disk array card performs another diagnosis, and if the diagnosis is successful, the hard disk will be put back online for data reconstruction and recovery. This causes the hard disk to be repeatedly online and offline, affecting the customer's system performance, and in serious cases, causing the system to crash.

[0072] To this end, the hard disk exception handling method provided in the present application greatly reduces the probability of system downtime due to system access to a faulty hard disk, thereby improving the system's stability, reliability, maintainability and product competitiveness.

[0073] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0074] Referring to FIG. 5 , FIG. 5 is a flowchart of a method for handling hard disk abnormality according to an embodiment of the present invention. The method may include the following steps:

[0075] S501: Analyze the received hard disk signal status of the target hard disk to obtain current hard disk status information of the target hard disk.

[0076] The hard disk signal status of the target hard disk can be detected by the disk array card, and the detected hard disk signal status of the target hard disk is transmitted to the complex programmable logic device. The complex programmable logic device receives the hard disk signal status of the target hard disk, and analyzes the received hard disk signal status of the target hard disk to obtain the current hard disk status information of the target hard disk.

[0077] The current hard disk status information may include hard disk error and hard disk normal.

[0078] The target hard disk can be any hard disk whose hard disk signal status is to be detected.

[0079] S502: When it is determined according to the current hard disk status information that a hard disk error exists in the target hard disk, hard disk error diagnosis is performed on the target hard disk to obtain a diagnosis result.

[0080] After parsing and obtaining the current hard disk status information of the target hard disk, it is determined whether the current hard disk status information indicates that the target hard disk has a hard disk error. When it is determined that the target hard disk has a hard disk error according to the current hard disk status information, a hard disk error diagnosis is performed on the target hard disk using a disk array card to obtain a diagnosis result.

[0081] The process of the disk array card performing hard disk error diagnosis on the target hard disk may include hard disk status detection by checking the hard disk health status, Self-Monitoring, Analysis and Reporting Technology (SMART) information, error count, etc. If the disk array card detects that the hard disk has an error, exceeds the threshold or other abnormal conditions, it will issue an alarm and record the corresponding event, which can be achieved through an alarm indicator, sound prompt or the alarm mechanism of the management software. By using the disk array card to perform hard disk error diagnosis on the target hard disk, effective monitoring of the hard disk health status is achieved. By timely issuing hard disk error warnings when hard disk abnormalities are detected, it is convenient for operation and maintenance personnel to perform hard disk maintenance in a timely manner.

[0082] S503: When the diagnosis result shows that the hard disk is normal, data reconstruction and recovery are performed on the target hard disk.

[0083] After performing hard disk error diagnosis on the target hard disk and obtaining the diagnosis result, if the diagnosis result shows that the hard disk is normal, it means that the hard disk error may be caused by an unstable link, and the data of the target hard disk is rebuilt (Rebuild) for recovery.

[0084] S504: When data reconstruction and recovery fails, obtaining data reconstruction and recovery record information corresponding to the target hard disk.

[0085] The data reconstruction and recovery process of the target hard disk is recorded in advance. After the data reconstruction and recovery of the target hard disk is performed, the data reconstruction and recovery result is monitored, and when the data reconstruction and recovery failure is detected, the data reconstruction and recovery record information corresponding to the target hard disk is obtained.

[0086] S505: When it is determined according to the data reconstruction and recovery record information that the current data reconstruction and recovery failure is a repeated reconstruction failure, the target hard disk is controlled to go offline through the power protection circuit.

[0087] The data reconstruction and recovery record information corresponding to the target hard disk records the data reconstruction and recovery process of the target hard disk. It is possible to determine whether the target hard disk has undergone a data reconstruction and recovery before this data reconstruction and recovery based on the data reconstruction and recovery process, and whether the data reconstruction and recovery result was a failure. When it is determined that the current data reconstruction and recovery failure is a repeated reconstruction failure based on the data reconstruction and recovery record information, the target hard disk is controlled to go offline through the power protection circuit. By controlling the target hard disk to go offline through the power protection circuit when repeated reconstruction failures occur, it is effectively prevented that the hard disk fails again after reconstruction, and the problem of repeated online reconstruction and offline causing impact on customer business performance is prevented, and the probability of system downtime due to system access to a faulty hard disk is greatly reduced, thereby improving the stability, reliability, and maintainability of the system.

[0088] It can be seen from the above technical solution that when the hard disk signal status of the target hard disk is analyzed and it is determined that the target hard disk has a hard disk error according to the current hard disk status information analyzed, the target hard disk is diagnosed for hard disk error, and when the diagnosis result is that the hard disk is normal, the target hard disk is reconstructed and restored for data. When data reconstruction and recovery fails, and it is determined that the data reconstruction and recovery failure is a repeated reconstruction failure according to the acquired data reconstruction and recovery record information, the target hard disk is controlled to go offline through the power protection circuit. By controlling the target hard disk to go offline through the power protection circuit when repeated reconstruction failures occur, it is effectively prevented that the hard disk fails again after reconstruction, and the problem of repeated online reconstruction and offline affects the customer's business performance, and the probability of system downtime due to system access to the faulty hard disk is greatly reduced, and the stability, reliability, maintainability of the system and the competitiveness of the product are improved.

[0089] It should be noted that, based on the above embodiment, the embodiment of the present invention also provides corresponding improved solutions. In the subsequent embodiments, the same steps or corresponding steps as those in the above embodiment can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be repeated one by one in the following improved embodiments.

[0090] Referring to FIG. 6 , FIG. 6 is a flowchart of another method for handling hard disk abnormality according to an embodiment of the present invention. The method may include the following steps:

[0091] S601: Receive a hard disk signal status of a target hard disk sent by a disk array card via a serial general purpose input / output signal.

[0092] After the disk array card detects the hard disk signal status of the target hard disk, the disk array card sends the hard disk signal status of the target hard disk to the complex programmable logic device through the serial general purpose input / output (SGPIO) signal. The complex programmable logic device receives the hard disk signal status of the target hard disk sent by the disk array card through the serial general purpose input / output signal. The hard disk signal status transmission through the serial general purpose input / output signal fully utilizes the advantages of the serial general purpose input / output signal using a single line for input and output, saving resources, supporting high-speed transmission, and low power consumption.

[0093] S602: Analyze the hard disk signal status to obtain the hard disk error signal setting status.

[0094] After receiving the hard disk signal status of the target hard disk, the hard disk signal status is analyzed to obtain the hard disk error (Fault) signal setting status.

[0095] S603: When the hard disk error signal setting state is the hard disk error enabling state, it is determined that a hard disk error exists in the target hard disk, and the target hard disk is set to a protection state through the disk array card.

[0096] After the hard disk error signal setting state is obtained through analysis, when the hard disk error signal setting state is the hard disk error enabling state, it can be set to enable the hard disk error when the hard disk error signal setting state is low, and it is determined that the target hard disk has a hard disk error, and the target hard disk is set to the protection state through the disk array card. By setting the target hard disk with a hard disk error to the protection state, the security and reliability of the data are enhanced.

[0097] S604: Record the hard disk drive failure assertion in the system event log, and perform hard disk error diagnosis on the target hard disk to obtain a diagnosis result.

[0098] After determining that the target hard disk has a hard disk error, the baseboard management controller records a hard disk drive fault assertion in the system event log, and performs hard disk error diagnosis on the target hard disk to obtain a diagnosis result. By recording the hard disk drive fault assertion in the system event log, effective recording of hard disk error status information is achieved, which facilitates subsequent decision-making by querying the status record information of the target hard disk.

[0099] S605: When the diagnosis result is that the hard disk is faulty, the target hard disk is removed from the system through the disk array card.

[0100] After the diagnosis result of the target hard disk is obtained, when the diagnosis result is a hard disk failure, the target hard disk is removed from the system through the disk array card. By removing the faulty hard disk in time, interference from the faulty hard disk is avoided.

[0101] S606: When the diagnosis result is that the hard disk is normal, the hard disk error signal setting state is set to a hard disk error disabled state, and the data reconstruction recovery signal setting state is set to a data reconstruction recovery enabled state.

[0102] When the diagnosis result is that the hard disk is normal, the hard disk error signal setting state is set to the hard disk error disabled state, such as it can be set to the hard disk error disabled state when the hard disk error signal setting state is high, and the data reconstruction recovery signal setting state is set to the data reconstruction recovery enabled state, such as it can be set to the data reconstruction recovery enabled state when the data reconstruction recovery signal setting state is low.

[0103] S607: Record the hard disk drive failure resolution and data reconstruction and recovery assertions in the system event log to perform data reconstruction and recovery on the target hard disk.

[0104] After the data reconstruction recovery signal setting state is set to the data reconstruction recovery enable state, the baseboard management controller is used to record the hard disk drive fault removal (disk drive fault deassert) and the data reconstruction recovery assertion (rebuid assert) in the system event log, and then the target hard disk is reconstructed and recovered. By recording the hard disk drive fault removal and the data reconstruction recovery assertion in the system event log, the target hard disk state is updated in a timely manner.

[0105] S608: When data reconstruction and recovery fails, retrieve data reconstruction and recovery record information corresponding to the target hard disk from the system event record log.

[0106] The data reconstruction and recovery process of the target hard disk is recorded in the system event log in advance. When the data reconstruction and recovery of the target hard disk is performed, the data reconstruction and recovery process is monitored. When the data reconstruction and recovery failure is detected, the data reconstruction and recovery record information corresponding to the target hard disk is retrieved from the system event log. By using the system event log to record the data reconstruction and recovery process of the target hard disk, a quick query of the data reconstruction and recovery record information corresponding to the target hard disk is achieved.

[0107] S609: When the data reconstruction and recovery is successful, the reconstruction completion information is recorded in the system event log.

[0108] When data reconstruction and recovery are successful, the reconstruction completion information is recorded in the system event log. By recording the reconstruction completion information in the system event log, it is convenient to track the data reconstruction and recovery results of the target hard disk in a timely manner by checking the system event log.

[0109] S610: When it is determined according to the data reconstruction and recovery record information that the current data reconstruction and recovery failure is a repeated reconstruction failure, receiving an enable control signal for a target power protection circuit corresponding to the target hard disk.

[0110] When the baseboard management controller determines that the data reconstruction and recovery failure is a repeated reconstruction failure according to the data reconstruction and recovery record information, it sends an enable control signal for the target power protection circuit corresponding to the target hard disk to the complex programmable logic device. The complex programmable logic device receives the enable control signal for the target power protection circuit corresponding to the target hard disk.

[0111] S611: controlling the target power protection circuit to be enabled according to the enable control signal to cut off the power supply of the target hard disk with a preset amplitude to make the target hard disk offline.

[0112] After receiving the enable control signal of the target power protection circuit corresponding to the target hard disk, the complex programmable logic device controls the target power protection circuit to be enabled according to the enable control signal, thereby cutting off the power supply of the target hard disk with a preset amplitude to make the target hard disk offline, such as cutting off the 12V power supply of the target hard disk. By controlling the target hard disk to go offline according to the enable control signal of the target power protection circuit corresponding to the target hard disk when repeated reconstruction failures occur, accurate control of the online status of the target hard disk is achieved.

[0113] See Figure 7, which is a logic diagram of a hard disk exception handling process in an embodiment of the present invention. When an exception occurs in the storage link and the system accesses the hard disk timeout, the disk array card monitors the hard disk information and sends it to the complex programmable logic device through the serial general purpose input and output signal. When the complex programmable logic device parses the serial general purpose input and output signal and obtains the hard disk error signal is set to low, the complex programmable logic device sends the fault hard disk drive fault information to the baseboard management controller through the serial communication bus signal, and the baseboard management controller system event log (sel) records the hard disk drive fault assertion information.

[0114] See Figure 8, which is a logic diagram of a hard disk fault diagnosis post-processing process in an embodiment of the present invention. The disk array card starts the diagnostic function and diagnoses the faulty hard disk. If the diagnosis passes, the complex programmable logic device obtains the hard disk error signal by parsing the serial general input and output signal and is set to high, and the reconstruction signal is set to low. The complex programmable logic device sends the fault hard disk error and reconstruction setting information to the baseboard management controller through the serial communication bus signal, and the baseboard management controller system event log will record the hard disk drive fault removal and data reconstruction recovery assertion information.

[0115] Refer to FIG9 , which is a logic diagram of hard disk status monitoring in an embodiment of the present invention. The hard disk is rebuilt, and the completion of the reconstruction will be recorded in the log of the baseboard management controller (complete rebuild). If the hard disk fails again during the hard disk reconstruction process, the disk array card sends the hard disk information to the complex programmable logic device through the serial general input and output signal, and the complex programmable logic device reports the hard disk error signal to the baseboard management controller by parsing. The baseboard management controller determines that the same hard disk is re-obtained after the reconstruction and the error information is set to low. The baseboard management controller sends a low signal to the complex programmable logic device through the serial communication bus signal. After the complex programmable logic device receives it, it pulls down the enable signal of the hard disk 12V power protection circuit that reports the error signal, so that the hard disk working voltage is powered off, thereby making the hard disk offline, thereby protecting the system. The logic of the baseboard management controller and the complex programmable logic device monitoring is as follows: when the baseboard management controller detects that hard disk X is being rebuilt, it will then start monitoring whether hard disk X has a drive error or is rebuilt. If a drive error occurs, a low signal will be sent to the complex programmable logic device through the serial communication bus, and the complex programmable logic device will pull down the enable signal of the hard disk 2V power protection circuit that reports the error signal; if the reconstruction is complete, the monitoring of the faulty hard disk is terminated.

[0116] The baseboard management controller monitors the rebuild of hard disk X and the related code of judgment logic is as follows:
