The second exception type may indicate that both the first cable and the second cable used to connect to the same hard drive are incorrectly connected and the abnormal connection methods are the same, that is, the second exception type may indicate that both the first cable and the second cable are incorrectly connected to their respective motherboard interfaces and the abnormal connection methods are the same.

[0044] In order to better understand the first and second exception types described in the embodiment of the present application, Figure 1 Provide explanation.

[0045] Figure 1 A schematic diagram of cable connection according to an embodiment of the present application is shown.

[0046] like Figure 1 As shown, the first cable A1 and the second cable B1, the first cable A2 and the second cable B2, and the first cable A3 and the second cable B3 are included.

[0047] Correct connection can indicate that the first cable and the second cable connected to the same backplane are connected to the corresponding motherboard interfaces of the mainboard in pairs, that is, the first cable A1 and the second cable B1 are connected to the corresponding motherboard interfaces of the mainboard in pairs. The first cable A2 and the second cable B2 are connected to the corresponding motherboard interfaces of the mainboard in pairs. The first cable A3 and the second cable B3 are connected to the corresponding motherboard interfaces of the mainboard in pairs.

[0048] For the first exception type, first cable A1 is correctly connected, second cable B1 is incorrectly connected, and the abnormal connection methods are different, resulting in first cable A1 and second cable B1 being unable to connect to their respective motherboard interfaces as a pair. First cable A2 and second cable B2 are both incorrectly connected, and the abnormal connection methods are different, resulting in first cable A2 and second cable B2 being unable to connect to their respective motherboard interfaces as a pair. First cable A3 is incorrectly connected, second cable B3 is correctly connected, and the abnormal connection methods are different, resulting in first cable A3 and second cable B3 being unable to connect to their respective motherboard interfaces as a pair.

[0049] For the second abnormality type, both first cable A1 and second cable B1 are incorrectly connected, and the abnormal connection method is the same, so that first cable A1 and second cable B1 are connected to the mainboard as a pair. Both first cable A2 and second cable B2 are incorrectly connected, and the abnormal connection method is the same, so that first cable A2 and second cable B2 are connected to the mainboard as a pair. First cable A3 and second cable B3 are correctly connected.

[0050] The inventive concept of the embodiments of the present application is described below with reference to the accompanying drawings.

[0051] With the continuous improvement of computer technology and the level of specialization, the complexity of computer systems is getting higher and higher, and the configuration types are becoming more and more complex. For example, in modern data centers, multiple hard disks can be configured for servers to meet data storage needs. The configuration location of the hard disk is relatively flexible, and the access methods and types of cables used to connect the hard disks are also diverse, and there may be abnormal cable connections. For example, the multiple cables may include a first cable and a second cable. The transmission rate of the first cable is greater than the transmission rate of the second cable. There may be a situation where the first cable is cross-connected or the second cable is cross-connected, for example, Figure 1 The first and second types of abnormalities mentioned above do not affect component identification and are therefore difficult to identify from the system side. However, during server maintenance or hard drive replacement, an abnormal cable connection may cause the hard drive to be incorrectly replaced, resulting in hard drive unavailability, data deletion, or even data loss.

[0052] To improve server availability, abnormal cable connections can be detected. However, because cables cannot be detected independently, they must be used in conjunction with other components. For example, these components may include at least one of a hard drive or a backplane. This increases the difficulty of detecting abnormal cable connections during the production phase.

[0053] As an implementation method, manual inspection can be used. For example, inspectors can visually inspect the cables while also performing human-computer interaction. For example, during the inspection phase, instructions can be used to illuminate the locator lights corresponding to the hard drives one by one. The inspector is then prompted to confirm the correct number, sequence, and color of the illuminated locator lights, and feedback is provided. This feedback can then be used to determine whether any cables are abnormally connected.

[0054] During the implementation of the present invention, we discovered that the test results obtained using the above-mentioned method were highly dependent on the feedback from the testers, and that testers could make mistakes or miss detections, thus affecting the accuracy of the test results. Furthermore, manual testing was time-consuming, affecting test efficiency.

[0055] Therefore, the embodiment of the present application analyzes the abnormal connection type and finds that there are Figure 1The two abnormality types shown are the first abnormality type and the second abnormality type. The first abnormality type may indicate that at least one of the first cable or the second cable is not correctly connected and the abnormal connection method is different. The second abnormality type may indicate that both the first cable and the second cable are not correctly connected and the abnormal connection method is the same. Since the characteristics of the two abnormality types are different, the embodiment of the present application proposes that a first detection operation of abnormal cable connection can be performed to determine whether the first abnormality type exists in multiple cables. A second detection of abnormal cable connection is performed to determine whether the second abnormality type exists in multiple cables. In addition, the first detection operation, the second detection operation, or the first detection operation and the second detection operation can be performed.

[0056] For the first abnormality type, it is found that the first cable can be used to transmit the hard disk configuration information (i.e., the first hardware information) in the hard disk information. The second cable can be used to transmit the hard disk configuration information (i.e., the second hardware information) in the hard disk information. The in-band detection method may include accessing at least one hard disk using at least one first cable. The out-of-band detection method may include accessing at least one hard disk using at least one second cable, thereby obtaining the first hardware information obtained using the in-band detection method and the second hardware information obtained using the out-of-band detection method, and then obtaining the detection result of whether the first abnormality type exists in multiple cables based on the first hardware information and the second hardware information. Based on the above, an embodiment of the present application proposes to perform a first detection operation based on the in-band detection method and the out-of-band detection method.

[0057] Regarding the second abnormality type, it was discovered that the presence of the second abnormality type in multiple cables can be determined by detecting whether at least one second cable has the second abnormality type. That is, if at least one second cable has the second abnormality type, it can also be indicated that at least one first cable also has the second abnormality type. If none of the at least one second cables have the second abnormality type, it can also be indicated that none of the at least one first cable has the second abnormality type. It was further discovered that the lighting of the positioning light can be controlled by the second cable. Therefore, the embodiment of the present application proposes that a second detection operation based on the positioning light detection method can be performed. In addition, it was discovered that the backplane configuration information (i.e., the second backplane information) in the backplane information can be accessed using the second cable. Therefore, the embodiment of the present application proposes that a second detection operation based on production information can be performed. For example, the first backplane information of the backplane obtained by the scanning operation and the second backplane information obtained by accessing the backplane using the second cable are used to obtain a detection result indicating whether the second abnormality type exists in at least one second cable.

[0058] In order to better understand the inventive concept of the embodiment of the present application, Figure 2 Provide explanation.

[0059] Figure 2A schematic diagram showing the principle of a method for detecting abnormal connections according to an embodiment of the present application is shown.

[0060] like Figure 2 As shown, for the first abnormality type, a first detection operation based on an in-band detection method and an out-of-band detection method can be performed. For the second abnormality type, a second detection operation based on a positioning light detection method can be performed. Optionally, a second detection operation based on production information can be performed.

[0061] The above describes the inventive concept of the embodiments of the present application. The following describes in detail the method, device, and electronic device for detecting abnormal cable connection provided by the embodiments of the present application with reference to the accompanying drawings.

[0062] First, combine Figure 3 , taking the computer system as the server and the communication protocol as the two-wire protocol as an example, the application scenarios applicable to the method for detecting abnormal cable connection are described. Figure 3 As an example, combining the application scenario shown in Figure 4 The method for detecting abnormal cable connection provided in an embodiment of the present application is described in detail.

[0063] It should be noted that the embodiments of the present application can be implemented independently or in combination with each other, and the same or similar concepts or processes will not be described in detail in some embodiments.

[0064] Figure 3 A diagram showing an application scenario of a method for detecting abnormal cable connection according to an embodiment of the present application is shown.

[0065] like Figure 3 As shown, the server may include a mainboard, a backplane, and a hard disk. The hard disk can be inserted into the server through a hard disk slot ( Figure 3 not shown) and backplane slots ( Figure 3 The first cable can be connected to the first type backplane port ( Figure 3 Not shown) and the first type motherboard interface ( Figure 3 Not shown). A second cable can be connected to a second type backplane port ( Figure 3 Not shown) and the second type motherboard interface ( Figure 3 not shown).

[0066] Thus, the server can execute the method for detecting abnormal cable connection described in the embodiment of the present application. It should be understood that Figure 3 This is merely an illustrative description and does not constitute a limitation on the scope of protection of this application.

[0067] The following will be based on Figure 3 The application scenario described, combined with Figure 4The method for detecting abnormal cable connection according to an embodiment of the present application is described in detail.

[0068] Figure 4 A flow chart of a method for detecting abnormal cable connection according to an embodiment of the present application is shown.

[0069] like Figure 4 As shown, the method includes operations S410 and / or S420.

[0070] In operation S410, a first detection operation of abnormal cable connection is performed to obtain a detection result of whether a first abnormal type exists in the plurality of cables. And / or

[0071] In operation S420, a second detection operation of abnormal cable connection is performed to obtain a detection result of whether a second abnormality type exists in the plurality of cables.

[0072] To determine whether at least one of the first abnormal type or the second abnormal type exists in multiple cables, at least one of the first detection or the second detection may be performed on the multiple cables, that is, S410, S420, or S410-S420 may be performed.

[0073] Regarding how to perform the first detection, it can be achieved in the following manner.

[0074] As an implementation method, a first detection operation based on in-band detection and out-of-band detection can be performed after the server is assembled. For example, based on the first hard disk information of at least one hard disk obtained using the in-band detection method and the second hard disk information of at least one hard disk obtained using the out-of-band detection method, a detection result of whether a first abnormality type exists in multiple cables is obtained. The first hard disk information can refer to the hard disk configuration information obtained using the in-band detection method. The second hard disk information can refer to the hard disk configuration information obtained using the out-of-band detection method.

[0075] Regarding how to perform the second detection, it can be achieved in the following manner.

[0076] As an implementation method, a second detection operation based on the positioning light detection method can be performed when the server assembly is completed. For example, at least one target backplane can be determined from multiple backplanes connected to multiple cables. The target hard disk number can be determined from the hard disk numbers of each of the multiple hard disks installed on the target backplane. For any target backplane among the at least one target backplane, the target positioning light corresponding to the target hard disk number can be controlled to light up. Based on the feedback information obtained on whether the actual hard disk corresponding to the actual positioning light and the target hard disk corresponding to the target hard disk number are the same, a detection result indicating whether there is a second abnormality type in at least one second cable used for the target backplane is obtained. The actual positioning light can be the positioning light that is actually lit on the target backplane.

[0077] As another implementation, a second detection operation based on production information is performed. For example, first backplane information obtained through a scanning operation and second backplane information obtained through accessing the backplane using a second cable are used to obtain a detection result indicating whether a second abnormality type exists in at least one second cable. The scanning operation can be performed during the server assembly phase.

[0078] According to an embodiment of the present application, since the first abnormality type indicates that at least one of the first cable or the second cable is incorrectly connected and the abnormal connection method is different, and the second abnormality type indicates that both the first cable and the second cable are incorrectly connected and the abnormal connection method is the same, the first abnormality type and the second abnormality type can cover various types of abnormal cable connections. By performing a first detection operation for abnormal cable connection, a detection result of whether the first abnormality type exists in multiple cables, and / or performing a second detection operation for abnormal cable connection, a detection result of whether the second abnormality type exists in multiple cables, a comprehensive detection of abnormal cable connection is achieved, improving detection accuracy and detection efficiency.

[0079] The following describes in detail how to perform the first detection operation based on the in-band detection method and the out-of-band detection method, the second detection operation based on the positioning light detection method, and the second detection operation based on production information with reference to the accompanying drawings.

[0080] 1. How to perform the first detection operation based on in-band detection and out-of-band detection

[0081] For at least one hard drive connected by multiple cables, the path for obtaining the first hard drive information of the hard drive based on the in-band detection method can be the first hard drive information of the motherboard first cable backplane hard drive. If the first cable is abnormally connected, it may be difficult to obtain the correct first hard drive information.

[0082] The path for obtaining the second hard disk information of the hard disk based on the out-of-band detection method can be the baseboard management controller of the motherboard, the second cable, the backplane management controller of the backplane, and the hard disk second hard disk information. If the second cable is abnormally connected, it may be difficult to obtain the correct second hard disk information.

[0083] Obtain first hard disk information for each of at least one hard disks obtained by performing a first detection operation using an in-band detection method. The first hard disk information may include the first hard disk serial number and the first hard disk drive letter. As an implementation method, the first hard disk information for each of the at least one hard disks may be obtained using a hard disk monitoring tool. For example, if the hard disk is a SATA hard disk or a SAS hard disk, the hard disk monitoring tool may include the smartctl command or PowerShell. The smartctl command may be used to monitor and manage the SMART (Self-Monitoring, Analysis, and Reporting Technology) function of the hard disk drive. If the hard disk is an NVMe (Non Volatile Memory Express) hard disk, the hard disk monitoring tool may include nvme-cli.

[0084] Obtain second hard disk information for each of the at least one hard disks obtained by performing a second detection operation using an out-of-band detection method. The second hard disk information may include the second hard disk serial number and the second hard disk drive letter. For example, the second hard disk information for each of the at least one hard disks may be obtained using a management interface. The management interface may include a web interface of a baseboard management controller. The web interface may include a Redfish interface. Redfish may be an open standard based on a RESTful API (Representational State Transfer Application Programming Interface) for server hardware management.

[0085] For any of the at least one hard disk drives, feedback information may be obtained as to whether the first hard disk information and the second hard disk information of the hard disk are identical. If the feedback information indicates that the first hard disk information and the second hard disk information of the hard disk are different, a detection result indicating that a first abnormality type exists in the first cable and the second cable used for the hard disk. If the feedback information indicates that the first hard disk information and the second hard disk information of the hard disk are identical, a detection result indicating that the first abnormality type does not exist in the first cable and the second cable used for the hard disk.

[0086] In order to better understand the first abnormality type of the embodiment of the present application, the following table 1 is used for explanation.

[0087] Table 1 shows the first hard disk information and the second hard disk information under the condition of correct connection according to the embodiment of the present application, as well as the first hard disk information and the second hard disk information under the condition of the first abnormality type. It should be noted that Table 1 is only an example and does not constitute a limitation on the scope of protection of this application.

[0088]

[0089] Table 1

[0090] As shown in Table 1, if there is a situation where the first hard disk information and the second hard disk information shown in Table 1 exist, since the first hard disk information and the second hard disk information of the hard disk are different, and since the second hard disk information is the same as the second hard disk information in the case of correct connection, the first hard disk information is different from the first hard disk information in the case of correct connection. Therefore, a detection result indicating that the first abnormality type exists in the first cable used for the hard disk can be obtained.

[0091] Since the in-band detection method includes accessing at least one hard disk using a first cable, and the out-of-band detection method includes accessing at least one hard disk using a second cable, the first hard disk information obtained using the in-band detection method indicates whether the first abnormality type exists in the first cable, and the second hard disk information obtained using the out-of-band detection method indicates whether the first abnormality type exists in the second cable. If the first cable and the second cable are both correctly connected, the first hard disk information and the second hard disk information of the same hard disk are the same. If at least one of the first cable or the second cable is not correctly connected and the abnormal connection method is different, the first hard disk information and the second hard disk information are different. Therefore, by using the first hard disk information of each at least one hard disk obtained by the in-band detection method and the second hard disk information of each at least one hard disk obtained by the out-of-band detection method to determine whether the first abnormality type exists in the first cable and the second cable for the hard disk, accurate detection of the first abnormality type is achieved.

[0092] 2. How to perform the second detection operation based on the positioning light detection method

[0093] For multiple backplanes connected by multiple cables, the path of the second detection operation based on the positioning light detection method can light up a specified positioning light for the baseboard management controller of the main board and the backplane management controller of the second cable backplane.

[0094] In order to reduce the probability of erroneous detection results caused by manual identification or misoperation, at least one target backplane can be determined from multiple backplanes connected to multiple cables. For example, there are N backplanes, namely backplane 1, ..., backplane n, ..., backplane N. N-1 backplanes can be determined from the N backplanes as target backplanes, that is, there can be N-1 target backplanes. For example, the N-1 target backplanes can include backplane 1, ..., backplane n, ..., backplane N-1. N can be an integer greater than 1. n can be an integer greater than or equal to 1 and less than or equal to N. In this way, the accuracy of the detection results is improved by reducing the number of hard disks to be detected.

[0095] In order to further reduce the probability of erroneous detection results, for any target backplane among at least one target backplane, the target hard disk number can be determined from the hard disk numbers of multiple hard disks installed on the target backplane, and a positioning light detection can be performed on the target hard disk corresponding to the target hard disk number.

[0096] How to determine the target hard disk from multiple hard disks can be achieved in the following ways.

[0097] As an implementation method, to ensure the comprehensiveness of the second detection operation, hard drives present in multiple target backplanes can be used as target hard drives. Thus, the target hard drive can be pre-determined from the multiple hard drives installed on the target backplane. For example, the target hard drive number can be pre-determined from the hard drive numbers of the multiple hard drives installed on the target backplane. The hard drive corresponding to the target hard drive number is the target hard drive. The target hard drive number can be the first hard drive number among the multiple hard drive numbers. Thus, the target hard drive can be the first hard drive among the multiple hard drives.

[0098] In order to better understand the method proposed in the embodiment of the present application of determining at least one target backplane from multiple backplanes and determining the target hard disk number from the hard disk numbers of multiple hard disks installed on the target backplane, the following is an explanation in conjunction with Table 2.

[0099] Table 2 shows the target backplane and target hard disk numbers determined based on the positioning light detection method according to an embodiment of the present application. It should be noted that Table 2 is only an example and does not constitute a limitation on the scope of protection of this application.

[0100]

[0101] Table 2

[0102] As shown in Table 2, when the number of backplanes is 1, 2, 3, 4, or 5, the corresponding detection count (i.e., the target number of backplanes) is 0, 1, 2, 3, or 4. If the number of backplane ports on backplane 1 is x, the number of backplane ports on backplane 2 is y, the number of backplane ports on backplane 3 is z, and the number of backplane ports on backplane 4 is w, then the hard disk numbers of the multiple hard disks installed on backplane 1 are 0 to x-1, the hard disk numbers of the multiple hard disks installed on backplane 1 are x to x+y-1, the hard disk numbers of the multiple hard disks installed on backplane 3 are x+y to x+y+z-1, and the hard disk numbers of the multiple hard disks installed on backplane 4 are x+y+z to x+y+z+w-1.

[0103] Based on the above, if the number of backplanes is 1, i.e., including backplane 1, there is no need to perform the second detection operation based on the positioning light detection method. If the number of backplanes is 2, i.e., including backplanes 1 and 2, backplane 1 can be used as the target backplane, and the target hard drive number is determined to be 0 from the hard drive numbers of the multiple hard drives installed in backplane 1.

[0104] When the number of backplanes is 3, that is, including backplane 1, backplane 2 and backplane 3, backplane 1 and backplane 2 can be used as target backplanes, and the target hard disk number is determined to be 0 from the hard disk numbers of the multiple hard disks installed on backplane 1, and the target hard disk number is determined to be x from the hard disk numbers of the multiple hard disks installed on backplane 2.

[0105] When the number of backplanes is 4, that is, including backplane 1, backplane 2, backplane 3 and backplane 4, backplane 1, backplane 2 and backplane 3 can be used as target backplanes, and the target hard disk number is determined to be 0 from the hard disk numbers of the multiple hard disks installed on backplane 1, the target hard disk number is determined to be x from the hard disk numbers of the multiple hard disks installed on backplane 2, and the target hard disk number is determined to be x+y from the hard disk numbers of the multiple hard disks installed on backplane 3.

[0106] When the number of backplanes is 5, that is, including backplane 1, backplane 2, backplane 3, backplane 4 and backplane 5, backplane 1, backplane 2, backplane 3 and backplane 4 can be used as target backplanes, and the target hard disk number is determined to be 0 from the hard disk numbers of the multiple hard disks installed on backplane 1, the target hard disk number is determined to be x from the hard disk numbers of the multiple hard disks installed on backplane 2, the target hard disk number is determined to be x+y from the hard disk numbers of the multiple hard disks installed on backplane 3, and the target hard disk number is determined to be x+y+z from the hard disk numbers of the multiple hard disks installed on backplane 4.

[0107] To further improve the accuracy of the detection results, a foolproof function can be added. As another implementation, the target hard drive can be randomly determined from multiple hard drives installed on the target backplane. For example, the target hard drive number can be randomly determined from the hard drive numbers of the multiple hard drives installed on the target backplane.

[0108] Based on this, the management interface of the baseboard management controller of the mainboard can send a lighting instruction to the backplane management controller of the backplane via the second cable. The lighting instruction may include the target hard disk number. In response to the lighting instruction, the backplane management controller controls the lighting of the target positioning light corresponding to the target hard disk number. Upon obtaining feedback information indicating that the actual hard disk corresponding to the actual positioning light and the target hard disk corresponding to the target hard disk number are different, a detection result indicating that a second abnormality type exists in at least one second cable used for the target backplane. Upon obtaining feedback information indicating that the actual hard disk corresponding to the actual positioning light and the target hard disk corresponding to the target hard disk number are the same, a detection result indicating that a second abnormality type does not exist in at least one second cable used for the target backplane.

[0109] The second detection operation based on pre-determining the target hard disk number from the hard disk numbers of the plurality of hard disks and based on randomly determining the target hard disk number from the hard disk numbers of the plurality of hard disks will be further described below.

[0110] 1. Second detection operation based on determining the target hard disk number from the hard disk numbers of multiple hard disks in advance

[0111] The second interactive page may include a target hard drive number, a second control, and a third control. The second control may indicate different feedback information for the actual hard drive corresponding to the actual locator light and the target hard drive corresponding to the target hard drive number. The third control may indicate the same feedback information for the actual hard drive corresponding to the actual locator light and the target hard drive corresponding to the target hard drive number.

[0112] A second interactive page may be displayed. When a trigger operation for the second control is detected, a detection result indicating that a second abnormality type exists in at least one second cable used for the target backplane is obtained. When a trigger operation for the first control is detected, a detection result indicating that the second abnormality type does not exist in at least one second cable used for the target backplane is obtained.

[0113] By displaying the target hard disk number, the second control and the third control on the second interactive page, the difficulty of determining whether at least one second cable used for the target backplane has a second abnormality type detection result is simplified, thereby improving convenience.

[0114] Furthermore, in order to improve the accuracy of the detection result, a detection result indicating that the at least one second cable of the target hard disk used for the target backplane does not have a second abnormality type may also be obtained.

[0115] 2. Second detection operation based on randomly determining the target hard disk number from the hard disk numbers of multiple hard disks

[0116] A mapping relationship can indicate the relationship between a hard drive number and a hard drive slot number. Thus, based on the actual hard drive number of the actual hard drive, the actual hard drive slot number of the actual hard drive can be determined from multiple mapping relationships. For example, an actual mapping relationship that matches the actual hard drive number can be determined from multiple mapping relationships. The hard drive slot number in the actual mapping relationship is then used as the actual hard drive slot number of the actual hard drive.

[0117] Thus, when feedback information indicating that the actual hard disk slot number of the actual hard disk and the target hard disk slot number are different is obtained, a detection result indicating that the second abnormality type exists in at least one second cable used for the target backplane. When feedback information indicating that the actual hard disk slot number and the target hard disk slot number are the same is obtained, a detection result indicating that the second abnormality type does not exist in at least one second cable used for the target backplane.

[0118] To obtain the actual slot number, you can use the following methods.

[0119] As an implementation, the first interactive page may include a first control that can be used to input an actual hard disk slot number of an actual hard disk or select an actual hard disk slot number from a plurality of candidate hard disk slot numbers.

[0120] In this way, the first interactive page can be displayed. When an input operation or a selection operation for the first control is detected, the actual hard disk slot number is obtained.

[0121] By using the first control on the first interactive page, the difficulty of determining whether at least one second cable used for the target backplane has a detection result of the second abnormal type is simplified, thereby improving convenience.

[0122] 3. Executing a Second Detection Operation Based on Production Information

[0123] During the production and assembly phase of the server, a scanning operation can be performed on the backplane information of any backplane among the multiple backplanes connected to the multiple second cables to obtain the first backplane information of the backplane. As an implementation method, the first backplane information can include the backplane slot number and the first backplane serial number associated with the backplane slot number. The second backplane information can include the backplane number and the second backplane serial number associated with the backplane number. Optionally, the motherboard information of the motherboard can also be obtained. When the first backplane information of each of the multiple backplanes is obtained, the first backplane information of each of the multiple backplanes can be associated with the motherboard information and stored in a database.

[0124] In addition, the backplane can be accessed using a second cable to obtain the second backplane information of the backplane. The path for obtaining the second backplane information of the backplane based on the second cable can be the baseboard management controller of the mainboard → the second cable → the backplane management controller of the backplane → the second backplane information. As an implementation method, field replaceable unit information can be obtained. The field replaceable unit information can be obtained using the second cable. The field replaceable unit information may include the second backplane information of each of multiple backplanes. If the second cable is abnormally connected, it may be difficult to obtain the correct second backplane information.

[0125] Thus, based on the first backplane information of each of the multiple backplanes and the second backplane information of each of the multiple backplanes, a detection result indicating whether the second abnormality type exists in the multiple second cables can be obtained. For example, for any of the multiple backplanes, if the first backplane information of the backplane and the second backplane information of the backplane are the same, a detection result indicating that the second abnormality type exists in the multiple second cables used for the backplane can be obtained. If the first backplane information of the backplane and the second backplane information of the backplane are different, a detection result indicating that the second abnormality type does not exist in the multiple second cables used for the backplane can be obtained.

[0126] Since the second backplane information of the backplane is obtained by accessing the backplane using the second cable, and the first backplane information of the backplane is obtained by performing a scanning operation on the backplane information of the backplane, if the second cable used for the backplane is correctly connected, the first backplane information and the second backplane information of the backplane are the same; if the second cable used for the backplane is not correctly connected, the first backplane information and the second backplane information of the backplane are different. Therefore, by using the first backplane information and the second backplane information obtained in different ways, it is determined whether there is a second abnormality type in the second cable used for the backplane, thereby achieving accurate detection of the second abnormality type.

[0127] Regarding how to obtain a detection result indicating whether the second abnormality type exists in the plurality of second cables based on the respective first backplane information of the plurality of backplanes and the respective second backplane information of the plurality of backplanes, this can be achieved in the following manner.

[0128] As an implementation, the target backplane numbers of the multiple backplanes can be obtained based on the sorting order of the backplane numbers of the multiple backplanes connected to the multiple second cables. For example, the backplane numbers of the multiple backplanes connected to the multiple second cables can be sorted in a predetermined order to obtain the target backplane numbers of the multiple backplanes. For example, the predetermined order can be from small to large starting from a predetermined value. The predetermined value can be 0. Thus, the second backplane information can include the target backplane number and the second backplane serial number associated with the target backplane number.

[0129] For any target backplane number among the multiple target backplane numbers, when the obtained feedback information indicates that the second backplane serial number associated with the target backplane number is the same as the first backplane serial number associated with the backplane slot number that is the same as the target backplane number, a detection result indicating that the second abnormality type does not exist in at least one second cable of the target backplane corresponding to the target backplane number is obtained. When the obtained feedback information indicates that the second backplane serial number associated with the target backplane number is different from the first backplane serial number associated with the backplane slot number that is the same as the target backplane number, a detection result indicating that the second abnormality type exists in at least one second cable of the target backplane corresponding to the target backplane number is obtained.

[0130] As another implementation, to further improve the accuracy of the detection results, this can be achieved by adding an information comparison dimension. For example, the first backplane information can also include the first backplane model. The second backplane information can also include the second backplane model. Thus, the first backplane model and the second backplane model can be compared based on the comparison of the first backplane serial number and the second backplane serial number.

[0131] For any target backplane number among multiple target backplane numbers, when the feedback information obtained indicates that the second backplane serial number associated with the target backplane number is the same as the first backplane serial number associated with the backplane slot number that is the same as the target backplane number, and the second backplane model associated with the target backplane number is the same as the first backplane model associated with the backplane slot number that is the same as the target backplane number, a detection result indicating that the second abnormality type does not exist in at least one second cable of the target backplane corresponding to the target backplane number is obtained. When the feedback information obtained indicates that the second backplane serial number associated with the target backplane number is different from the first backplane serial number associated with the backplane slot number that is the same as the target backplane number, and / or the second backplane model associated with the target backplane number is different from the first backplane model associated with the backplane slot number that is the same as the target backplane number, a detection result indicating that the second abnormality type exists in at least one second cable of the target backplane corresponding to the target backplane number is obtained.

[0132] The above describes the method for detecting abnormal cable connection provided by the embodiment of the present application.

[0133] Based on the above content, the method for detecting abnormal cable connection provided in an embodiment of the present application is generally described below.

[0134] For the first abnormality type, an embodiment of the present application determines whether the first hard disk information and the second hard disk information of at least one hard disk are the same based on the first hard disk information of at least one hard disk obtained using an in-band detection method and the second hard disk information of at least one hard disk obtained using an out-of-band detection method, so as to determine whether the first abnormality type exists in the first cable and the second cable used for the at least one hard disk. The in-band detection method may include accessing the at least one hard disk using the at least one first cable. The out-of-band detection method may include accessing the at least one hard disk using the at least one second cable.

[0135] Based on the above, the cross connection between the first cable and the second cable is detected.

[0136] For the second type of anomaly, the present embodiment of the application designs a foolproof method for the second detection operation based on the positioning light detection method, simplifies the human interaction environment, and performs human-computer interaction detection on a per-backplane basis, covering all backplanes. For the second detection operation based on production information, the present embodiment of the application utilizes the first backplane information obtained by scanning and the second backplane information obtained by accessing multiple backplanes using the second cable to automatically detect multiple second cables.

[0137] Based on the above, it is possible to detect the situation where the first cable and the second cable are connected incorrectly in pair.

[0138] This embodiment of the application improves the detection method for abnormal cable connections based on the original server detection method, improving the accuracy and efficiency of the detection results. In addition, by optimizing the detection method, the server performance can meet user requirements, thereby improving the quality of server shipments and enhancing user confidence and satisfaction.

[0143] The second obtaining module 520 is configured to perform a second detection operation for abnormal cable connection and obtain a detection result indicating whether a second abnormality type exists in the plurality of cables.

[0144] According to an embodiment of the present application, the plurality of cables may include a first cable and a second cable. The transmission rate of the first cable may be greater than the transmission rate of the second cable. The first exception type may indicate that at least one of the first cable or the second cable is incorrectly connected and the abnormal connection methods are different. The second exception type may indicate that both the first cable and the second cable are incorrectly connected and the abnormal connection methods are the same.

Alternatively, at least one of the first obtaining module 510 and / or the second obtaining module 520 can be at least partially implemented as a computer program module that, when executed, can perform the corresponding functionality.
