Detailed Description
The controller is used as one of core devices of the solid state disk, so that the problem is difficult to locate when the problem is bad, and the controller is often required to cooperatively locate in multiple fields such as a software engineer, a hardware engineer, a production line FA engineer, a test engineer and the like. The current production line is used as the private field of each manufacturer, the industry does not have a unified standard flow for analyzing and positioning the problems, most of the problems depend on personal experience of FA engineers, components are replaced when the direction is suspected, or a disc is one-to-one, bad discs are independently analyzed, and no universal automatic flow exists. For manufacturers with huge output, the method is too low in efficiency for processing the problem plates, and accumulation of the problem plates can be caused, so that the production efficiency and the supply rhythm are seriously affected.

The process is automatically realized without manual intervention, so that the problem of the controller is conveniently determined by maintenance personnel who does not know the internal principle of the solid state disk, and the analysis, positioning and production efficiency are improved.
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 and 2, the method includes the steps of:
s101, after a fault disc determined on a production line is inserted into a server, PCIe equipment identification is carried out.
Specifically, the fault disc can be a to-be-analyzed bad problem disc which appears in a production line when the solid state disk is subjected to factory testing.
After the failed disk is inserted into the server, the server may perform PCIe (PCI-Express, PERIPHERAL COMPONENT INTERCONNECT EXPRESS, a high speed serial computer expansion bus standard) device identification for the failed disk.
Illustrating: the disc PCIe state may be obtained by executing a lspci |grep solid state disc fault location command, where the solid state disc fault location is a disc software defined PCIe state, specified by vendor software development, which is not specifically limited.
If the faulty disk has a master control welding problem or a power supply problem, a PCIe device may not be identified. Thus, in the event that no PCIe device is identified, step S102 may be performed; when the PCIe device can be identified, step S103 may be performed.
S102, if the PCIe device is not identified, outputting fault location information of master control welding or power supply of the fault disk.
The fault location information may be printed out, or may be presented in other manners, such as flashing a corresponding signal light or outputting a sound.
If the disc has no PCIe state, namely PCIe equipment cannot be identified, printing prompt can be carried out, and the probability (99%) is that serious faults such as offset occur in main control welding, the prior AOI detection is not detected, or obvious problems occur in power supply of the disc, and the power supply of the disc needs to be checked.
And S103, if the PCIe device is identified, the firmware is burned into the fault disk, and then the flash memory is identified.
If the PCIe display is normal, that is, the PCIe device can be identified, then the corresponding disk can be found, and then the corresponding firmware is burned into the disk. The firmware to be burned may be preset firmware for testing, or may be firmware that needs to be burned to the hard disk during actual production so that the hard disk may be normally used for storing the firmware under the scene.
After burning into firmware, flash memory identification, also known as disk identification, may be performed on the failed disk, i.e., nvme identification. For example, command nvme list is executed after burning, and it is observed whether nvme device is present at this time.
If nvme is not recognized, step S104 is executed, and if nvme is recognized, step S105 is executed.
And S104, if the flash memory is not identified, acquiring a disc log of the fault disc, determining a fault point by using the disc log, and outputting fault positioning information of the fault point of the fault disc.
If no nvme devices are present, i.e., no flash memory is identified, a disk log may be derived, which may be used to determine a point of failure. After determining the fault point, outputting the fault locating information of the fault point of the fault disc.
In one specific embodiment of the present application, determining a fault point by using a disc log, and outputting fault location information of the fault point on the fault disc, includes:
Determining whether all hardware units inside the controller of the failed disk are started by utilizing the disk log;
if not, determining the fault point as the defect of the main control body, and outputting fault positioning information of the defect disc with the defect of the main control body;
If yes, checking whether the initialization of the main control to the flash memory is abnormal, and if the initialization of the flash memory of a certain channel fails, outputting fault location information of the abnormal channel of the fault disc.
That is, in the case that the nvme devices can be identified, it may be determined whether or not the core (hardware unit, i.e., core) inside the controller of the failed disk is started based on the record of the disk log after the disk log is acquired.
In one embodiment of the present application, determining whether all hardware units within a controller of a failed disk have been started using a disk log includes:
Capturing keywords of a disc log;
based on whether all the core has been started at the key index master initialization.
That is, the key words in the disk log can be grasped, and whether all the cores are started or not when the index master control is initialized. The index analysis is performed by the keywords, so that the judging process can be accelerated.
If the core is not started, the initialization exception is indicated, and the initialization exception can be defined as bad main control body, and the main control needs to be replaced.
If all the core initialization of the main control is normal, checking whether the initialization of the main control on the nand (a flash memory used for storing data in a solid state disk) is abnormal, and prompting the corresponding abnormal channel when the nand initialization of a certain channel fails, so that a maintainer can check the corresponding channel, thereby reducing the checking range.
S105, if the flash memory is identified, acquiring the bandwidth state of the fault disk, determining a fault point by utilizing the bandwidth state, and outputting fault location information of the fault point of the fault disk.
If the nvme devices can be identified normally at this time, a failure point can be determined based on the bandwidth status, thereby outputting failure location information that the failed disk exists at the failure point.
In one specific embodiment of the present application, determining a failure point by using a bandwidth status, and outputting failure location information of the failure point on the failed disk, including:
Judging whether the bandwidth state is matched with the standard bandwidth state of the fault disc;
if the bandwidth states are matched, determining that the bandwidth states are normal;
If the two types of the data are not matched, determining that the bandwidth state is abnormal, determining that the fault point is the master control welding or PCIe link hardware connection, and outputting fault positioning information of the master control welding or PCIe link hardware connection of the fault disk.
Due to the solid state disk failure, abnormal bandwidth status may be caused, such as bandwidth reduction, rate reduction, and the like. The bandwidth state anomaly is often related to the master welding and PCIe link hardware connection anomaly, and therefore, by comparing the bandwidth state with the standard bandwidth state, it can be determined whether the fault location information of the master welding or PCIe link hardware connection exists on the fault disk is output.
Specifically, when the bandwidth state is matched with the standard bandwidth state of the fault disk, the bandwidth state is normal, if the bandwidth state is not matched with the standard bandwidth state, the bandwidth state is abnormal, at the moment, the fault point can be determined to be the main control welding or PCIe link hardware connection, and fault positioning information about the connection of the fault disk in the main control welding or PCIe link hardware connection can be printed.
In one embodiment, determining whether the bandwidth status matches a standard bandwidth status of a failed disk includes:
Judging whether the bandwidth in the bandwidth state is consistent with the standard bandwidth in the standard bandwidth state, and whether the rate in the bandwidth state is consistent with the rate in the step bandwidth state;
If yes, determining that the bandwidth state is matched with the standard bandwidth state, performing IO test on the fault disk, performing fault location processing and outputting fault location information;
if not, determining that the bandwidth state is not matched with the standard bandwidth state;
Correspondingly, if the bandwidth state is abnormal, determining the fault point as the master control welding or PCIe link hardware connection, and outputting fault positioning information of the master control welding or PCIe link hardware connection of the fault disk, wherein the method comprises the following steps:
if the speed of the fault disc is smaller than the standard speed in the standard bandwidth state, determining the fault point as the master control welding, and outputting fault positioning information of the fault disc in the master control welding;
If the bandwidth of the fault disk is smaller than the standard rate in the standard bandwidth state, determining the fault point as PCIe link hardware connection, and outputting fault positioning information of the fault disk in the PCIe link hardware connection;
wherein the PCIe link hardware connection comprises a hardware connection from the connector to the master PCIe link.
That is, the bandwidth state may specifically include bandwidth and rate, when the matching determination is performed, the bandwidth state and the rate need to be compared, and when the bandwidth state and the rate keep the matching state, the bandwidth state is clear to be normal, otherwise, the bandwidth state is abnormal.
For different abnormal conditions, the fault point can be accurately positioned according to specific abnormal conditions, and specific fault point prompts are output.
Illustrating: whether the bandwidth of the disc is normal or not can be confirmed through commands lspci-s bdf-vvv, wherein bdf is bus_id corresponding to the disc. Then, through lspci |grep solid state disk fault location acquisition, for a disk bandwidth state, such as a disk of PCIE4.0, the command acquisition state is 16GT/s x4, wherein 16GT/s is the speed of the disk, and x4 is the bandwidth of the disk. And when an abnormal state of mismatch occurs, performing printing prompt. If the disk is reduced (i.e., the current speed is lower than the standard speed, for example, 16GT/s is changed to 8 GT/s or 5GT/s, and the high probability is that the controller is in welding, the subsequent checking and maintenance are performed, if the reduced bandwidth is present (i.e., the current bandwidth is lower than the standard bandwidth), x4 is changed to x2 or x1, and the hardware connection of the disk from the connector to the main control PCIe link is checked, the possibility of the hardware welding problem on the link is the greatest, and the corresponding printing prompt is performed.
After the fault disc determined on the production line is inserted into the server, PCIe equipment identification is carried out by applying the method provided by the embodiment of the application; if the PCIe device is not identified, outputting fault positioning information of master control welding or power supply of the fault disk; if the PCIe device is identified, the firmware is burned into the fault disk, and then flash memory identification is carried out; if the flash memory is not identified, a disc log of the fault disc is obtained, a fault point is determined by using the disc log, and fault positioning information of the fault point of the fault disc is output; if the flash memory is identified, the bandwidth state of the fault disk is acquired, the fault point is determined by utilizing the bandwidth state, and the fault locating information of the fault point of the fault disk is output.
In the application, after the fault disk determined on the production line is inserted into the server, PCIe equipment identification is firstly carried out on the fault disk, if PCie equipment cannot be identified, the problem of main control welding or power supply of the fault disk is indicated, the fault positioning information of the fault disk in the main control welding or power supply can be directly output, and the fault disk is convenient to be checked and the fault problem is processed based on the fault positioning information. If the flash memory cannot be identified, fault points can be carried out based on disc logs, and fault positioning information of the fault points of the fault disc is output; if the flash memory can be identified, the bandwidth state of the fault disk can be acquired, the fault point is determined by utilizing the bandwidth state, and the fault location information of the fault point of the fault disk is output.
The technical effects are as follows: by inserting the fault disc into the server for a series of equipment identification, information acquisition and judgment, etc., specific fault points in the fault disc can be determined, and fault orientation information corresponding to the fault points can be output. The positioning efficiency of controller problem in the solid state disk can be effectively improved, the high-efficiency positioning and maintenance of maintenance personnel can be facilitated, the abnormal main control problem can be subjected to subsequent classification, and batch problems can be found in time.
It should be noted that, based on the above embodiments, the embodiments of the present application further provide corresponding improvements. The preferred/improved embodiments relate to the same steps as those in the above embodiments or the steps corresponding to the steps may be referred to each other, and the corresponding advantages may also be referred to each other, so that detailed descriptions of the preferred/improved embodiments are omitted herein.
In a specific embodiment of the present application, if the bandwidth status is normal, the fault point may also be determined by performing an IO test on the fault disk. Referring to fig. 3, the specific implementation process includes:
IO test is carried out on the fault disc;
In the IO test process, restarting the equipment and carrying out flash memory identification again under the condition that the flash memory is lost when the disk is dropped;
If the flash memory is identified, outputting fault location information of abnormal connection of the fault inventory on the PCIe link hardware, detecting the PCIe link hardware connection, determining a false soldering object or a material poor object, determining the false soldering object or the material poor object as a fault point, and outputting the fault location information of the fault inventory on the false soldering object or the material poor object;
if the flash memory is not identified, outputting fault location information of the fault disc with abnormal controller.
In this embodiment, the IO test refers to a read-write test performed on the solid state disk.
Specifically, the IO test process is sequential reading and writing of a fault disc and random reading and writing of different pressures. If the phenomenon of losing nvme devices occurs when the disk is dropped in the IO test, the machine can be restarted automatically, and the state of the disk is confirmed again through a command nvme list.
If nvme equipment can be identified by nvme list commands at this time, then a device fault is indicated on the link, related devices on the PCIe link need to be checked, whether the link from the connector to the main control has cold joint or poor materials can be checked by means of related means, and at this time, a printing prompt exists at the terminal; if the links are repeatedly confirmed to be all problems, the software can be suspected to have BUG (referring to logic errors in the program).
In a specific embodiment of the present application, in an IO test process, if a flash memory is not identified, outputting fault location information that a fault disk has a controller abnormality, including:
in the IO test process, if the flash memory is not identified, capturing a hardware unit register interacted with the flash memory in the controller;

if not, outputting fault location information of abnormal register values in the fault disk existing controller;
if yes, acquiring a current disc log, and determining whether the controller crashes a hardware unit by using the current disc log; if the hardware unit crashes, outputting fault positioning information of the hardware unit crashes in the fault disk existing controller.
That is, if the memory is not identified to be deleted in the IO test process, the hardware unit register interacted with the flash memory in the controller may be grabbed, so as to check whether the target register corresponding to the main control in the hardware unit register is normal, and output corresponding fault location information according to different judgment results.
In one embodiment of the present application, if no hardware unit crash occurs, the method further includes:
capturing uncorrectable error keywords of a controller hardware unit in a current disc log, and judging whether uncorrectable errors occur or not;
If yes, outputting fault location information of the fault disc with abnormal controller.
When the hardware unit is not crashed, whether the uncorrectable error occurs can be judged by judging whether the disk log has the uncorrectable error key word. When an uncorrectable error occurs, it may also be determined that the failed disk is in the controller exception.
