[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on August 15, 2023, with application number 202311026712.6 and application name “Fault location method, equipment, device, storage medium and electronic device”, all contents of which are incorporated by reference into this application. Technical Field

[0004] Today is an era of data explosion. Massive amounts of data are generated every day. Professional storage devices provide the possibility of storing this huge amount of data. Among these massive amounts of data, some data are very important, such as financial data, experimental data, etc. This requires storage devices to be not only functional but also reliable.

[0005] However, storage devices inevitably experience hardware wear and tear during long-term operation. This wear and tear can cause hardware anomalies, which in turn can lead to software anomalies. Hardware link failure is a common hardware failure, manifesting as a fault occurring in one or more segments of a long hardware link. Existing technologies cannot accurately identify the location or extent of a fault on a long link. Therefore, intelligently repairing the entire link increases the scope of repair and reduces efficiency.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0051] FIG1 is a flow chart of a fault location method according to an embodiment of the present application. As shown in FIG1 , the method includes the following steps:

[0052] Step S102, obtaining a login status of at least one target port in a target link having a fault, wherein the target link is used to connect to a target port of at least one hard disk according to a preset link sequence;

[0053] Step S104: querying the impact factor corresponding to each login state in a preset set, wherein the preset set is used to record multiple login states and the impact factor corresponding to each login state;

[0054] Step S106: accumulating the impact factor corresponding to each target port one by one according to the preset link order, and comparing each accumulation result with the preset positioning threshold;

[0055] Step S108 : When the accumulated result is greater than the preset positioning threshold, the target port corresponding to the last accumulated impact factor is determined to be a faulty port.

[0056] In an embodiment of the present application, the login status of at least one target port in a target link with a fault is obtained, wherein the target link is used to connect to the target port of at least one hard disk in a preset link order; the impact factor corresponding to each login status is queried in a preset set, wherein the preset set is used to record multiple login statuses and the impact factor corresponding to each login status; the impact factor corresponding to each target port is accumulated one by one in the preset link order, and each accumulated result is compared with a preset positioning threshold; when the accumulated result is greater than the preset positioning threshold, the target port corresponding to the last accumulated impact factor is determined to be the faulty port, and the faulty port where the fault occurs can be determined in the target link with the fault, thereby achieving the technical effect of accurately locating the fault position of the faulty target link, thereby solving the technical problem that the prior art cannot accurately locate the fault position in the link.

[0057] Optionally, the above fault location method may be used in a storage system having multiple hard disks, where the multiple hard disks may store data in a disk array.

[0058] Optionally, each hard disk may include two preset ports, which are respectively recorded as a first preset port and a second preset port.

[0059] Optionally, there may be two preset links, namely a first preset link and a second preset link, wherein the first preset link is used to connect the first preset port of each hard disk, and the second preset link is used to establish the second preset port of each hard disk.

[0060] Optionally, the first preset link may be used to transmit uplink data, and the second preset link may be used to transmit downlink data.

[0061] Optionally, the target link is a preset link with a fault, and the target port is a port connected to the preset link with a fault.

[0062] In the above step S102 , the login status may indicate a frame loss situation of the corresponding target port or the preset port.

[0063] Optionally, the login status includes: GOOD, indicating no frame loss exception; IN DOUBT, indicating that there is at least one frame loss, but it has not reached the level of DEGRADED; DEGRADED, indicating that there is a certain amount of frame loss, which is greater than IN DOUBT but has not reached the level of EXCLUSION; indicating that there is a large amount of frame loss in the EXCLUDSION disk.

[0064] In the above step S104, the impact factor is used to represent the degree of frame loss of the target port or the preset port in a numerical manner.

[0065] Optionally, different login states have different impact factors, for example, GOOD=0, IN DOUBT=1, DEGRADED=4, EXCLUDSION=10.

[0066] In the above step S106, the preset positioning threshold is used to locate the position of the fault in the target link. In the target link with the fault, the impact factor corresponding to each target port in the target link is accumulated one by one, and each accumulation result is compared with the preset positioning threshold. If the accumulated impact factor corresponding to a certain target port is greater than the preset positioning threshold, it means that there is a fault at the subsequently accumulated target port, and the faulty port is located, which facilitates subsequent maintenance or isolation of the faulty port.

[0067] Optionally, the location information of each hard disk and preset port can be recorded in advance. The location information includes at least: preset chassis information and preset controller information. The preset chassis information is used to indicate the unique identifier of the chassis where each hard disk is located, and the preset controller information is used to indicate the unique identifier of the controller connected to the preset port of the hard disk in each chassis. After determining the faulty port, the preset controller information of the faulty port can be queried to locate the faulty port.

[0068] It should be noted that the preset port of each hard disk is connected to the preset link through a controller. Since the controller and the preset port correspond one to one, the faulty port can be located by determining the controller of the faulty port.

[0069] As an optional embodiment, before obtaining the login status of at least one target port in a target link with a fault, the method also includes: obtaining the login status of at least one preset port in a preset link, wherein the preset link is used to connect to a preset port of at least one hard disk; querying the impact factor corresponding to each login status in a preset set, wherein the preset set is used to record multiple login statuses and the impact factor corresponding to each login status; accumulating the impact factors of all preset ports in the preset link to determine an evaluation result of the preset link; when the evaluation result is greater than a preset fault threshold, determining that the preset link is a target link with a fault.

[0070] In the above embodiment of the present application, before locating the fault in the faulty target link, it is necessary to determine one by one whether each preset link belongs to the target link with the fault. Then, in the process of determining the target link, the impact factor corresponding to each preset port in each preset link can be accumulated to obtain an evaluation result of the preset link. Then, the evaluation result of the preset link is compared with the preset fault threshold. If the evaluation result of the preset link is greater than the preset fault threshold, it indicates that the preset link has a fault. In this case, the preset link is determined to be the target link, thereby achieving preliminary positioning of the target link with the fault.

[0071] As an optional embodiment, before obtaining the login status of at least one preset port in a preset link, the method also includes: sending broadcast information to the hard disk set to be detected, wherein the hard disk set to be detected includes at least one hard disk, and each hard disk includes two preset ports; receiving location information returned by the hard disk set to be detected, wherein the location information includes at least: preset chassis information and preset controller information, the preset chassis information is used to indicate the unique identifier of the chassis where each hard disk is located, and the preset controller information is used to indicate the unique identifier of the controller connected to the preset port of the hard disk in each chassis; determining the preset link based on the preset chassis information and the preset controller information, wherein the preset link is used to cascade controllers with the same identifier in multiple chassis.

[0072] In the above-mentioned embodiment of the present application, the location information of each hard disk and the preset port of each hard disk can be obtained through broadcast information. After the faulty port is determined, the location of the faulty port and the hard disk on which it is located can be determined from the location information, thereby facilitating the isolation or repair of the faulty port.

[0073] As an optional embodiment, obtaining the login status of at least one preset port in a preset link includes: detecting the frame loss information of each preset port, wherein the frame loss information includes at least the number of frame losses; determining a preset frame loss interval corresponding to the number of frame losses in a preset interval set as a target frame loss interval, wherein the preset interval set includes multiple preset frame loss intervals, and each preset frame loss interval is pre-set with a corresponding preset frame loss status; and determining the target frame loss status corresponding to the target frame loss area as the login status.

[0074] In the above-mentioned embodiment of the present application, the login status represents the frame loss situation of the corresponding target port or preset port. Therefore, the login status can be determined according to the number of frame losses. By pre-dividing multiple preset frame loss intervals and setting a corresponding preset frame loss status for each preset frame loss interval, the preset frame loss interval corresponding to the number of frame losses of the preset port or target port is determined as the target frame loss interval, and the preset frame loss status of the target frame loss interval is used as the login status of the preset port or target port, thereby realizing the determination of the login status.

[0075] As an optional embodiment, after obtaining the login status of at least one preset port in the preset link, the method also includes: when the login status indicates that there is an abnormality in the preset port, obtaining the login status of the preset port at the target time according to a preset time interval; when the login status of the preset port at the target time still indicates that there is an abnormality in the preset port, isolating the hard disk where the preset port is located.

[0076] In the above embodiment of the present application, if the hard disk occasionally has a small amount of frame loss, it can be tolerated by the storage system. However, if the hard disk frequently has frame loss, the hard disk needs to be processed. Therefore, when it is detected that the login status of the preset port is abnormal, the login status of the preset port can be obtained again at the target time according to the preset time interval. If the login status of the preset port at the target time still indicates that the preset port is abnormal, it means that the preset port has frequent frame loss, and the hard disk where the preset port is located needs to be separated from the storage system to isolate the faulty hard disk.

[0077] As an optional embodiment, isolating the hard disk where the preset port is located includes: determining the hard disk where the preset port is located as the target hard disk; setting the target hard disk to a closed state, wherein when the target hard disk is in the closed state, all ports of the target hard disk are disconnected.

[0078] In the above-mentioned embodiment of the present application, multiple hard disks can establish a disk array in a RAID manner. Then, when a hard disk in the disk array fails, the failed hard disk can be set to a closed state Fail. When a hard disk in the closed state Fail is detected in the RAID array, the hard disk is exited, thereby achieving the technical effect of isolating the failed hard disk.

[0079] As an optional embodiment, after accumulating the influence factors of all preset ports in the preset link and determining the evaluation result of the preset link, the method further includes: judging whether the evaluation result is greater than a preset redundancy threshold; if the evaluation result is greater than the preset redundancy threshold, determining that the preset link is an abnormal link; determining the total link of the abnormal links, wherein the total link includes two preset links; and adjusting the redundancy flag of the total link, wherein the redundancy flag includes: a first redundant flag indicating that an abnormal link exists in the total link, and a second redundant flag indicating that no abnormal link exists in the total link.

[0080] In the above embodiment of the present application, each general link in the storage system can be set with two preset links, and the two preset links serve as redundant backups for each other. If one of the preset links has an abnormality, the other preset link can be used to continue data transmission. Therefore, it is necessary to timely understand the redundancy status of the general link, and then the evaluation results of the corresponding impact factors of all preset ports in each link in the general link can be compared with the preset redundancy threshold. If the evaluation result is greater than the preset redundancy threshold, it means that the preset link has an abnormality, and it is necessary to call another redundant preset link in the general link to meet the data transmission requirements, and add a first redundancy mark to the general link; and then if both of the two preset links in the general link have abnormalities, it means that the general link can no longer meet the data transmission requirements, and it is necessary to shut down and alarm, waiting for maintenance.

[0081] As an optional embodiment, after determining that the last accumulated target port is a faulty port, the method further includes: obtaining target controller information of the faulty port, wherein the target controller information is a unique identifier of the controller connected to the faulty port; obtaining target chassis information of the hard disk where the faulty port is located, wherein the target chassis information is a unique identifier of the chassis of the hard disk where the faulty port is located; and generating alarm information based on the target controller information and the target chassis information.

[0082] As an optional embodiment, after obtaining the target controller information of the faulty port and the target chassis information of the hard disk where the faulty port is located, the method further includes: determining the upstream port of the faulty port, wherein the upstream port is used to transmit data for the faulty port; obtaining the upstream controller information of the upstream port, wherein the upstream controller information is a unique identifier of the upstream port connected to the controller; obtaining the upstream chassis information of the hard disk where the upstream port is located, wherein the upstream chassis information is a unique identifier of the chassis of the hard disk where the upstream port is located; and generating alarm information based on the target controller information, the target chassis information, the upstream controller information and the upstream chassis information.

[0083] In the above embodiment of the present application, the alarm information includes the enclosure_index of the chassis where the controller is located (that is, the target chassis information), the canister_index of the controller (that is, the target controller information), the enclosure_index of the upstream chassis connected to the faulty controller (that is, the upstream chassis information) and the canister_index of the upstream controller (that is, the upstream controller information). A line is limited by two points in the alarm information to determine the fault location, thereby achieving accurate positioning of the fault location.

[0084] As an optional embodiment, after generating the alarm information, the method further includes: displaying the alarm information through a graphical user interface.

[0085] As an optional embodiment, after obtaining the login status of at least one target port in the faulty target link, the method also includes: when the login status indicates that there is an abnormality in the target port, obtaining the login status of the target port at the target time according to a preset time interval; when the login status of the target port at the target time still indicates that there is an abnormality in the target port, isolating the hard disk where the target port is located.

[0086] In the above embodiment of the present application, if the hard disk occasionally has a small amount of frame loss, it can be tolerated by the storage system. However, if the hard disk frequently loses frames, the hard disk needs to be processed. Therefore, when it is detected that the login status of the target port is abnormal, the login status of the target port can be obtained again at the target time according to the preset time interval. If the login status of the target port at the target time still indicates that the target port is abnormal, it means that the target port has frequent frame loss, and the hard disk where the target port is located needs to be separated from the storage system to isolate the faulty hard disk.

[0087] As an optional embodiment, isolating the hard disk where the target port is located includes: determining that the hard disk where the target port is located is the target hard disk; setting the target hard disk to a closed state, wherein when the target hard disk is in the closed state, all ports of the target hard disk are disconnected.

[0088] In the above-mentioned embodiment of the present application, multiple hard disks can establish a disk array in a RAID manner. Then, when a hard disk in the disk array fails, the failed hard disk can be set to a closed state Fail. When a hard disk in the closed state Fail is detected in the RAID array, the hard disk is exited, thereby achieving the technical effect of isolating the failed hard disk.

[0089] As an optional embodiment, after determining that the last accumulated target port is a faulty port, the method further includes: obtaining a redundant tag of the total link where the target link is located, wherein the redundant tag includes: a first redundant tag indicating that an abnormal link exists in the total link, and a second redundant tag indicating that no abnormal link exists in the total link; when the second redundant tag exists in the total link, fault isolation is performed on the target controller that controls the faulty port.

[0090] In the above-mentioned embodiment of the present application, each general link in the storage system can be set with two preset links, and the two preset links serve as redundant backups for each other. If an abnormality occurs in one of the preset links, the other preset link can be used to continue data transmission. Furthermore, in the process of isolating the fault port, it is possible to first determine whether the general link has the redundancy condition that meets the fault isolation based on the redundancy mark of the general link, and then, if a second redundancy mark exists in the general link, indicating that there is no abnormal link in the general link, the fault isolation of the fault port can be achieved.

[0091] This application also provides an optional embodiment, which provides a storage hardware link status monitoring method based on hard disk command frame loss. Based on analyzing the number of hard disks experiencing frame loss and the severity of individual frame loss, the location of the faulty link can be identified, and corresponding fault isolation measures can be taken according to different link failures, effectively ensuring system stability. When a failure occurs, the cause of the failure can be accurately identified and corresponding treatment can be performed. The fault location or range can be accurately identified over a very long link.

[0092] Figure 2 is a schematic diagram of the architecture of a storage hardware link status monitoring method based on hard disk command frame loss according to an embodiment of the present application. As shown in Figure 2, it includes: chassis management layer (EN), protocol layer, driver layer, and physical link layer.

[0093] Optionally, the physical link layer is at the lowest layer and is a physical channel for command or data transmission between the storage system and the hard disk.

[0094] Optionally, the protocol layer and the driver layer are data channels for communication between the storage system and the hard disk.

[0095] Optionally, the chassis management layer is located at the top layer and its function is to determine the fault location based on the frame loss degree (ie, login status) of each hard disk returned by the protocol layer, and trigger a fault isolation action.

[0096] Optionally, each hard drive has two default ports, and the frame loss degree (i.e., login status) of each default port is divided into four levels:

[0097] GOOD: No frame loss exceptions, and the impact factor on EN is 0.

[0098] IN DOUBT: Frame loss exists: at least one frame loss occurs, but it has not reached the level of DEGRADED. The impact factor on EN is 1.

[0099] DEGRADED: The disk has frame loss: a certain amount of frame loss, greater than IN DOUBT but not reaching EXCLUSION level, affects EN by a factor of 4.

[0100] EXCLUDSION: The disk has a large amount of frame loss, affecting EN by a factor of 10.

[0101] Optionally, the chassis management layer records two attributes (i.e., location information) for each hard drive: the chassis where the hard drive is located and the controller where the hard drive is located. When a single hard drive experiences frame loss, it is considered a single-disk failure, but anti-shake processing is required to avoid misoperation. When multiple hard drives experience frame loss, the probability of multiple hard drives losing frames simultaneously is very small, so the fault may not be on the disk itself. In this case, multiple thresholds need to be set to superimpose the impact factors of multiple hard drives to determine whether the threshold has been reached and the chassis and controller where these disks are located. This further determines where the fault occurred in the hardware link. The chassis management layer then performs corresponding fault isolation operations based on the detected fault location and promptly reports an alarm.

[0102] In the above-mentioned embodiments of the present application, the storage device can promptly detect whether there is a link failure in the frame, and then perform corresponding troubleshooting on the abnormal link, thereby ensuring the security and reliability of the storage system and guaranteeing product quality and production services.

[0103] As an optional embodiment, the implementation process of the storage hardware link status monitoring method based on hard disk command frame loss includes the following steps:

[0104] Step S1: The storage system starts and runs normally.

[0105] In step S2, the SAS Expander chip is a programmable chip that can publish broadcast events. After receiving the broadcast, the chassis management layer (EN) initiates Discovery (also known as the discovery mechanism). After Discovery is completed, the EN can obtain the chassis information (enclosure_index) where the hard disk is located and the controller information (canister_index) corresponding to each preset port of each hard disk, that is, obtain the location information.

[0106] In step S3, EN subscribes to the frame loss information of each port preset by each hard disk in the protocol layer, and checks the frame loss information after each Discover is completed.

[0107] In step S4, the protocol layer returns the command execution status through the SCSI protocol rules and the driver, and sets the frame loss status of each port preset port of each disk. The frame loss status is recorded as the login status of the disk.

[0108] Optionally, the login status (i.e., login status) includes: GOOD: no frame loss exception; IN DOUBT: frame loss exists: at least one frame loss exists, but it has not reached the level of DEGRADED; DEGRADED: frame loss exists: a certain number of frame losses, greater than IN DOUBT but not reaching the level of EXCLUSION; and EXCLUDSION: a large number of frame losses exist.

[0109] Step S5: Different login states (ie, login states) described by the protocol layer for the disk have different impact factors on EN, GOOD=0, IN DOUBT=1, DEGRADED=4, EXCLUDSION=10.

[0110] Step S6: Determine the preset links Strand and the total link Chain, wherein each total link Chain includes two preset links Strand.

[0111] FIG3 is a schematic diagram of a storage hardware link according to an embodiment of the present application. As shown in FIG3 , enclosure 0 is the main cabinet, enclosures 1-3 are hard disk frames (i.e., chassis) corresponding to enclosure_index=1-3, and each chassis is divided into upper and lower parts corresponding to canister_index=0 and 1. The hard disks are distributed in enclosures 1-3, and each chassis is cascaded in a straight line through SAS cables. The hardware link from the same SAS port of the main cabinet to the bottom of the cascade is recorded as the preset link strand. Each disk and the preset port correspond to a preset link strand. The two preset link strands with symmetry between the upper and lower controllers are recorded as a total link chain.

[0112] In step S7, when the EN detects multiple disk login anomalies on a strand, it accumulates the impact factors corresponding to each disk login. This requires setting three thresholds: a preset failure threshold T1, a preset location threshold T2, and a preset redundancy threshold T3.

[0113] Optionally, the preset fault threshold T1 is the cumulative value of the impact factors of the login status (i.e., login status) of all corresponding hard disks on the entire preset link Strand and the color number node port, which must be at least greater than 30 to meet the simultaneous EXCLUDSION of at least three disks.

[0114] Optionally, the preset positioning threshold T2 is the cumulative value of the influencing factor of the login status (i.e., login status) of the preset port port of the hard disk corresponding to a controller on the current preset link Strand. T2 is less than T1 and can be calculated as 6 points to find the location of the first fault point on a single preset link Strand.

[0115] Optionally, the preset redundancy threshold T3 is the total chain threshold. T3 is smaller than T1 because the total chain represents a pair of preset strands. When both preset strands have abnormal login status (i.e., login status), it indicates that there is no redundant link, and the storage system is extremely unsafe. Therefore, if T3 is lower than T1, the total chain abnormality alarm is reported first. When the cumulative impact factor of the disk login status (i.e., login status) of each of the two preset strands in a total chain exceeds T3, the variable (i.e., redundancy flag) is set to bad_chain+1 (the initial value of bad_chain is 0).

[0116] Step S8: After the statistics of the accumulated values ​​of the impact factors of login (ie login status) on each preset link Strand are completed, the abnormal point judgment of the link fault begins.

[0117] In step S9, when the login status (i.e., login status) of the disks on the preset link Strand is greater than T1, it means that multiple disks have login (i.e., login status) abnormalities. The probability of multiple disks (at least 3 disks) simultaneously experiencing frame loss is very small, so it can be considered that there is a problem in a certain section of the preset link Strand.

[0118] In step S10, the cumulative impact factors of the login status (i.e., login status) of the disks corresponding to all controllers on the strand found to have a fault in step S9 are compared with T2. The first controller whose cumulative impact factor for the disk is greater than T2 is found. This controller is the controller that first failed (corresponding to the failed port).

[0119] In step S11, after the first faulty controller is found, the controller needs to be isolated for fault.

[0120] Optionally, during fault isolation, if the value of bad_chain in step S7 is less than 1, the physical link of the controller's uplink port is found. At this time, the controller and the downstream controller on the same preset link Strand as the controller will no longer have the hard disk frame loss problem, achieving the purpose of fault isolation. Then, an alarm of frame loss of the controller is reported. The alarm information must include the enclosure_index of the chassis where the controller is located, the canister_index of the controller, the enclosure_index of the upstream chassis connected to the faulty controller, and the canister_index of the upstream controller. A line is limited by two points in the alarm information to determine the fault location.

[0121] Optionally, if the value of bad_chain in step S7 is greater than 1, it means that the storage link has no redundancy at this time, and only the above alarm needs to be reported.

[0122] In step S12, when the EN finds that only one disk on a preset strand has a login exception (the login status of a single disk is not differentiated), it considers the disk with the login exception to be a problem of the disk itself. The storage system allows occasional disk login exceptions, but cannot tolerate disk login exceptions all the time. Therefore, when a single disk login exception is first discovered, the EN performs anti-shake processing, starts a 1h timer, and records the disk with the login exception in the context of the EN module.

[0123] Optionally, after the timer expires (i.e., at the target time), the latest disk login status (i.e., login status) is obtained. If a disk login error occurs at this time and it is the same disk that experienced the error 1 hour ago, an alarm is reported for this disk. Upon detecting the alarm, the RAID module can set the disk to Fail status, removing it from the RAID. If the EN detects a disk Failure, it shuts down the disk's physical default port to isolate the fault. The user then locates the faulty disk based on the alarm information and performs a replacement.

[0124] Step S13: Through the above steps, the storage system can automatically identify whether it is a point failure (disk) or a line failure (disk, controller) when a link failure occurs, and perform corresponding hardware fault isolation to prevent more software anomalies and ensure storage stability.

[0125] In step S14, all the above-mentioned alarms are displayed to the user through the GUI interface.
