In the technical solution provided in step S202, the target hard disk may include, but is not limited to, a hard disk disposed on a server, for example, an SAS hard disk, an SATA hard disk, or an NVME hard disk, and in case of a hard disk failure, in order to improve efficiency of positioning the failed hard disk by a maintenance personnel, the target indicator lamp of the target hard disk may be, but is not limited to, controlled to be in a display state corresponding to the failure, so as to further improve a position of the failed hard disk by the maintenance personnel.

Optionally, taking an indicator light corresponding to the hard disk to be turned on as an example, the hard disk backboard may be turned on in the following two manners, but not limited to: first, for SAS or SATA hard disk, lighting information is sent to the back plate by the SGPIO bus, and the CPLD is responsible for resolving SClock, SLoad, SDataOut and sdaatain signals in the SGPIO bus, and outputs lighting signals to indicator lamps (e.g., LED lamps or other indicator lamps) corresponding to the hard disk after resolving is completed. Secondly, for the NVME hard disk, after receiving the NVME bit information sent by the CPLD through the VPP, the CPU returns the location/Error information of the NVME hard disk to the CPLD to carry out the operation of lighting the hard disk back plate.
However, due to various factors such as design, operation, or collision members, abnormal lighting of the back plate of the hard disk often occurs, for example, the hard disk fault actually indicated by the indicator lamp may not be consistent with the hard disk fault actually indicated by the hard disk, for example, the hard disk does not correspond to the position of the indicator lamp, the issued indicator lamp controls the indicator lamp to display blue, but the indicator lamp displays red. In such a case, it is necessary to perform a localization analysis of the failure point.

And the fault of the indicator lamp is determined through the real control signal and the real control information, so that the reliability of the determined fault of the indicator lamp is improved.
Optionally, in this embodiment, the identifier of the target hard disk may include at least one of letters, numbers and character strings, where each hard disk in a group of hard disks corresponds to one-to-one and different identifiers, and in this way, accurate division of each hard disk is achieved.
In the technical solution provided in step S204, the actual control information may be, but is not limited to, used for determining a prediction control signal when the hard disk failure actually indicated by the target indicator light of the target hard disk is inconsistent with the hard disk failure actually indicated by the target hard disk, where the prediction control signal is used for controlling the target indicator light to be in a prediction display state, and the prediction display state is used for indicating that the first hard disk failure occurs in the target hard disk.
Alternatively, in this embodiment, the prediction control signal may, but is not limited to, be not sent to the target indicator, but the prediction control signal is determined according to the actual control information, so as to determine the correct predicted display state of the target indicator.
In one exemplary embodiment, the predictive control signal may be determined from the actual control information, but is not limited to, by: acquiring an actual hard disk fault identifier carried in the actual control information; determining the predicted display state according to the actual hard disk fault identification; generating the predictive control signal for representing the predictive display status.
Optionally, in this embodiment, the actual control information may, but not limited to, carry an actual hard disk failure identifier of the target hard disk, where the actual hard disk failure identifier may, but not limited to, include at least one of letters, numbers and character strings, and each hard disk failure has a one-to-one correspondence and a different identifier, so that by this way, accurate distinction of the failure occurring in the hard disk is achieved.
Alternatively, in the present embodiment, the predictive control signal for representing the predictive display state may be generated by, but not limited to, the following means: and determining a predicted state identifier corresponding to the predicted display state, and recording the predicted state identifier on a target bit of a predicted control signal, wherein different predicted display states have one-to-one corresponding state identifiers, the predicted control signal comprises a plurality of bits, the plurality of bits comprise the target bit, and one bit in the plurality of bits is used for recording the state identifier corresponding to the display state of one indicator lamp of the target hard disk.
Optionally, in this embodiment, the actual hard disk failure identifier carried in the actual control information may be an identifier of a hard disk failure actually occurring in the target hard disk, or may not be an identifier of a hard disk failure actually occurring in the target hard disk, and it is understood that an actual hard disk failure identifier carried in the actual control information may also be wrong.
In one exemplary embodiment, the predictive display status may be determined, but is not limited to, from the actual hard disk failure identification by: and determining the predicted display state corresponding to the actual hard disk fault identification from a preset set of corresponding relations, wherein the set of corresponding relations comprises a one-to-one correspondence relation between N hard disk fault identifications and N display states, the N hard disk fault identifications are used for representing N hard disk faults, the N display states are N display states of the target indicator lamp, and N is a positive integer greater than or equal to 2.

Optionally, in this embodiment, the predicted display state corresponding to the actual hard disk failure identifier may be determined from a set of corresponding relationships, for example, taking N hard disk failure identifiers including a hard disk failure identifier 1, a hard disk failure identifier 2, and a hard disk failure identifier 3, and one-to-one correspondence between the hard disk failure identifier 1, the hard disk failure identifier 2, and the hard disk failure identifier 3 and the display state 1, the display state 2, and the display state 3 as an example, where the hard disk failure identifier 1 fails, it may be determined that the predicted display state corresponding to the hard disk failure identifier 1 is the display state 1 from a set of corresponding relationships.
In the solution provided in step S206, the indicator fault of the indicator may be a line between the motherboard and the back board (for example, before the CPLD), a CPLD itself problem (for example, code related) or a back board hardware line (for example, after the CPLD), etc., so as to determine the indicator fault of the target indicator, the indicator fault of the target indicator may be determined according to, but not limited to, the prediction control signal, the actual control signal, the prediction display state and the actual display state.

In one exemplary embodiment, the first comparison result may be obtained by, but is not limited to, comparing the predicted control signal and the actual control signal by: comparing the amplitude of the predicted control signal with the amplitude of the actual control signal; in the case where the magnitude of the predictive control signal and the magnitude of the actual control signal are the same, the first comparison result is determined to indicate that the predictive control signal and the actual control signal are the same.
Alternatively, in this embodiment, the predicted control signal of the target indicator light may be determined from the first set of control signals, and the actual control signal of the target indicator light may be determined from the second set of control signals, where the target hard disk has a plurality of indicator lights, the plurality of indicator lights include the target indicator light, the first set of control signals is used to represent the predicted control signals of the plurality of indicator lights, and the second set of control signals is used to represent the actual control signals of the plurality of indicator lights.

For example, in the case where a hard disk failure occurs in the hard disk, the amplitude of the control signal is 1, in which case the display color of the indicator lamp is red, and in the case where the amplitude of the control signal is 0, the indicator lamp is turned off. Then, if the magnitude of the predictive control signal is 1 and the magnitude of the actual control signal is 0, in such a case, the first comparison result is determined to indicate that the predictive control signal and the actual control signal are different; if the magnitude of the predictive control signal is 1 and the magnitude of the actual control signal is 1, in such a case, the first comparison result is determined to indicate that the predictive control signal and the actual control signal are identical.
By the method, whether the predicted control signal is identical to the actual control signal or not is determined by comparing whether the amplitude of the predicted control signal is identical to the amplitude of the actual control signal or not, and efficiency of determining whether the actual control signal is wrong or not is improved.
In one exemplary embodiment, the indicator light fault that the target indicator light has may be determined, but is not limited to, by one of the following:
in a first aspect, when the first comparison result is used to indicate that the predicted control signal is the same as the actual control signal, and the second comparison result is used to indicate that the predicted display state is the same as the actual display state, the indicator lamp fault is determined to be an error in the actual control information, or it is determined that an actual hard disk fault identifier carried in the actual control information is different from a fault identifier of the first hard disk fault.
Optionally, in this embodiment, when the first comparison result is used to indicate that the predicted control signal is the same as the actual control signal, and the second comparison result is used to indicate that the predicted display state is the same as the actual display state, it may indicate that the actual control signal output by the CPLD in analyzing the actual control information is accurate, and the predicted display state is the same as the actually observed state of the indicator light, and in this case, it is determined that the indicator light fault occurred in the target indicator light is an actual control information issuing error, for example, packet loss or messy code occurs in the process of transmitting the actual control information to the CPLD; or determining that the indicator light fault of the target indicator light is different from the actual hard disk fault identifier carried in the actual control information and the fault identifier of the hard disk fault actually occurred in the hard disk, for example, the fault 1 of the hard disk fault actually occurred in the hard disk, but the fault identifier of the fault 2 is carried in the actual control information.
In a second mode, when the first comparison result is used for indicating that the predicted control signal is the same as the actual control signal, and the second comparison result is used for indicating that the predicted display state is different from the actual display state, the indicator lamp fault is determined to be a fault of a hardware circuit connected with the target indicator lamp, wherein the hardware circuit is used for receiving the actual control signal sent to the target indicator lamp by the target indicator lamp.

Alternatively, in this embodiment, in the case where the first comparison result is used to indicate that the predicted control signal and the actual control signal are different, it may be understood that the actual control signal output by the CPLD analyzing the actual control information is inaccurate, in which case, the fault of the indicator light is determined to be an error in the generated actual control signal, for example, the code of the CPLD itself has a problem, and in which case, it is necessary to check the code of the lighting analysis portion of the CPLD reversely.
By the method, the fault of the indicator lamp, which is generated by the target indicator lamp, is automatically determined according to the actual control signal, the predicted control signal, the actual display state and the predicted display state, the efficiency of determining the fault of the indicator lamp is improved, and the efficiency of determining the cause of the fault of the indicator lamp is determined for maintenance personnel.
For a better understanding of the fault determination method in the embodiments of the present application, the fault determination process in the implementation of the present application is explained and illustrated below in connection with alternative embodiments, which may be, but are not limited to, applicable to the embodiments of the present application.
On a software level, developing a hard disk backboard lighting fault location system based on Visual Studio (or c++ or other computer language, which is not limited in this application), the system comprising: the system comprises a data acquisition unit, a logic calculation unit and a fault positioning unit.
On the hardware level, the upper computer is connected with the backboard CPLD through JTAG (Joint Test Action Group ) and is used for capturing lighting information transmitted by SGPIO (Serial General Purpose Input/Output bus, serial universal input/Output bus), VPP (Voltage Protection Protocol bus, power supply potential bus) and I2C (Inter-Integrated Circuit, serial dual-line interface) buses in real time; the upper computer is connected to a main board BMC (Baseboard Management Controller ) through a UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver/Transmitter) for capturing serial port logs, such as: SAS (Serial Attached SCSI ), SATA (Serial Advanced Technology Attachment, serial ATA), or NVME (Non-Volatile Memory Express, nonvolatile memory expansion) disk logs; and reading and writing the register information of the backboard CPLD to send a lighting instruction to the backboard CPLD. Fig. 3 is a schematic diagram of an alternative hardware connection according to the implementation of the present application, as shown in fig. 3, for the NVME hard disk, the CPU (Central Processing Unit ) goes up to the MCIOX8, and issues the lighting information through the VPP bus. For SAS and SATA hard disks, the upper behavior PCH (Platform Controller Hub ), SAS card, RAID (Redundant Array of Independent Disks Card, redundant array of independent disks card) card, or expander card goes to Slimline X4, and issues lighting information through the SGPIO bus. Aiming at NVME, SAS or SATA hard disk, BMC can issue lighting information to the backboard CPLD through a 12C bus, and meanwhile, BMC and backboard CPLD can also perform other data interaction in a mode of reading and writing backboard CPLD register information. It will be appreciated that: each type of hard disk has two lighting modes, and the two modes are independent. The upper computer acquires required data through accessing the UART interface of the main board and the JTAG interface of the back board, and performs back board lighting fault positioning analysis.
Data acquisition unit-JTAG interface: the upper computer establishes connection with the backboard CPLD through a JTAG interface, and acquires SGPIO, VPP, I C lighting information input into the CPLD and lighting signals output by the CPLD by adopting a boundary scanning technology. The basic idea of boundary scan is: a shift register unit (boundary scan register, which is first equivalent to the target register) is added to the input/output pins near the chip. The register unit can isolate the chip from peripheral input and output circuits, so that continuous observation of input and output signals of the chip is realized.
Data acquisition unit-UART interface: the upper computer is connected to the main board BMC through a UART interface, and establishes communication with the backboard CPLD through an I2C bus. After the backboard CPLD I2C address is obtained, backboard lighting fault reproduction and verification under the I2C bus can be directly realized by clicking "error", "location", "rebuild" on the hard disk backboard lighting fault positioning system.
Logic calculation unit: the read data of the backplate CPLDVPP, SGPIO, I2Cpin foot is preprocessed from 0/1 data to waveform data (for debug view verification and analysis). And on the other hand, analyzing key information in the data to obtain lighting signals output by the CPLD.
Fault locating unit: based on the upstream lighting information, the CPLD output by the logic calculation unit is analyzed to obtain a lighting signal (corresponding to a prediction control signal), and the lighting signal (corresponding to an actual control signal) output by the CPLD stored in the captured register is compared to perform abnormal lighting fault location.
Fig. 4 is a schematic diagram of an alternative issue of control information according to an embodiment of the present application, as shown in fig. 4, for the NVME hard disk, the CPU or Switch issues lighting information (corresponding to control information) through the VPP bus. VPP is a set of host SMBUS (System Management Bus ), 8bit data represents 1 port,1 port corresponds to one NVME hard disk, and the data bits used may include, but are not limited to, bit0, bit1, and bit4.
Fig. 5 is a schematic diagram two of an alternative control information issuing, as shown in fig. 5, for an SAS/SATA hard disk, lighting information thereof is issued through an SGPIO bus according to an embodiment of the present application. The high level of the first SLoad indicates the last bit of the last set of lighting information, and the lighting information of the hard disk is stored in the SDataOut signal. The lighting information of each hard disk is indicated by 3 bits, active, locate, error information, and active can be regarded as a read-write lamp (yellow-green lamp), local is a positioning lamp (blue lamp), and Error is a fault lamp (red lamp). The blue and red lights are both lighted as powder lights. CPLD analyzes SGPIO protocol and lights the location/Error LED lamp by using location information and Error information. It should be noted that, at present, all Active lighting information of the hard disk is given to the CPLD by the hard disk itself to control lighting, the CPLD plays a role of transparent transmission, and the Active lighting information given to the CPLD by the uplink (such as a motherboard and the like) is shielded by the CPLD, so that only location and Error information need to be considered.
FIG. 6 is a schematic diagram of an alternative fault determination method according to an embodiment of the present application, as shown in FIG. 6, may include, but is not limited to, the following steps:
in step S601, a physical connection is established between the motherboard BMC and the UART interface, and between the motherboard PLD and the JTAG interface. After the hardware circuit is completed, a program is started and the system is entered.
Step S602, when the back panel is abnormal, may include, but is not limited to: drop down select hard disk type (SAS/SATA hard disk or NVME hard disk); the model of the backboard CPLD (104 pin number or 206pin number) is selected by pulling down; confirming the corresponding pin of CPLD connected with the uplink SGPIO bus or VPP bus; confirming the corresponding pin of the CPLD which is connected with an LED lamp (yellow-green lamp, blue-red lamp or E1.S hard disk lamp) in a downlink manner; and confirming the corresponding pin of the CPLD connected by the uplink BMC through the I2C bus.
In step S603, click the "run" button, the data acquisition unit captures the uplink lighting information data and the downlink lighting signal register information, and reproduces the back panel lighting abnormal fault site. For example, the up lighting information data stored in the register is captured based on JTAG boundary scan for the corresponding pin of the CPLD connected to the up SGPIO bus or VPP bus, and the down lighting signal information stored in the register is acquired.
In step S604, the "operation" button is clicked, the logic calculation unit performs data processing and calculation, outputs the lighting information data waveform received by the CPLD, and outputs the lighting signal that the CPLD should theoretically analyze.
In step S605, click the "debug" button, and locate the fault occurring in the indicator lamp by the fault location unit, for example, for the corresponding pin of the CPLD downlink LED lamp, compare the lighting signal (high/low level, or 1/0) output by the logic operation with the register information (1 or 0) of the actually read corresponding LED pin of the CPLD. If the results are consistent with the actual observed LED lamp state, proving that the abnormal lighting is caused by the error issuing of the uplink instruction; if the two results are consistent, but are consistent with the actually observed LED lamp state U, the lighting abnormality is proved to be caused by the problem of a hardware circuit between the backboard CPLD and the LED lamp; if the results are inconsistent, the lighting abnormality is proved to be caused by the problem of the CPLD code itself, and the CPLD lighting analysis part code needs to be reversely checked.
In step S606, since the upper computer and the backboard CPLD are physically connected through the JTAG interface, if the fault point is located as a problem in the CPLD code itself, the "debug" button can be directly clicked, the backboard CPLD FW file is exported and modified, and after the modification is completed, the "burn" button is clicked to update the backboard CPLD FW, so as to perform debug result verification.
Step S607, repeating the above steps S602 to 606, and verifying the back panel lighting abnormality under the I2C bus control. Note that, the analysis process of the lighting information transmitted by SGPIO, VPP, I C has independence in the CPLD code, and needs to be separately analyzed and verified.
According to the fault determination method in the embodiment of the application, a hard disk backboard lighting fault positioning system is added on the basis of the existing server backboard hardware circuit. The CPLD uplink VPP, SGPIO, I C data transmission is grabbed and displayed in a waveform form, and preparation is made for debug fault point positioning. Aiming at the VPP and SGPIO lighting, the fault area can be quickly positioned, and debug efficiency is improved. The system can directly interact with the BMC, and can send out a lighting instruction through the I2C, so that analysis and verification under the I2C lighting line are realized. CPLD FW can be directly exported/burned through JTAG interface for code modification and verification, thereby helping to quickly locate fault points and improving debug efficiency under hard disk lighting abnormal scene.
