Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a memory fault detection method, a device and a medium thereof.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
In the practical application of the current server, the server is usually configured with a plurality of memories, when an operating system of the server detects that a memory is unavailable, an error message is returned, and further, an indicator lamp arranged at a memory card slot is controlled to be powered on to emit light. However, the operating system can only know which memory is unavailable, and cannot know the reason why the memory is unavailable, and at present, the specific reason for the memory failure is mostly determined by inquiring the memory information of the BIOS.
For BIOS, it is a set of programs that are fixed on a Read-Only Memory (ROM) chip on the motherboard of a computer, and its main function is to provide the lowest level, most direct hardware setup and control for the computer. It stores the most important basic input and output program of computer, self-checking program after starting up and system self-starting program, it can read and write the specific information set by system from CMOS, in which the setting information about the server memory is the above-mentioned memory information. The operation and maintenance personnel of the server can firstly power off the server, clear the CMOS in a cap-jumping mode, enter the BIOS Setup, and perform fault memory positioning and fault reason determination by checking memory information.
Because the requirement on the operation and maintenance personnel is relatively high, the operation and maintenance personnel needs to know the cap jump and the BIOS to a certain extent, the steps are relatively complicated, the efficiency is low, and the quick recovery of the server memory is not facilitated, so the memory fault detection method is provided by the application, and is applied to a server with communication connection between a base plate Management Controller (BMC) and the BIOS, and comprises the following steps:
s11: and obtaining the memory information obtained after the BIOS self-inspection.
Due to the characteristics of the BIOS, the BIOS can perform self-check after the server is powered on, wherein the information about the memory part in the boot information obtained by the self-check, namely the memory information, can reflect the current memory condition of the server.
S12: and positioning the fault memory according to the memory information and judging the fault reason.
S13: and returning corresponding fault information according to the fault memory and the fault reason.
The fault information includes the location information of the fault memory and the fault reason, so that operation and maintenance personnel can locate the fault memory and distinguish different memory fault reasons.
Further, the fault cause that can be determined according to the memory information includes, but is not limited to: memory corruption, memory not in place, and memory not trained.
It is easy to understand that, the above method for determining the cause of the memory failure according to the memory information is not essentially different from the method for manually determining the cause of the memory failure by acquiring the memory information by the operation and maintenance staff at present, and the determination is performed by data on a specific data bit of the memory information. For example, when the memory is not trained, no data exists in the corresponding memory information data bit, and when the memory is not trained, the corresponding memory information data bit displays corresponding abnormal information.
Similarly, the positioning information of the faulty memory may also be determined according to the data bits corresponding to the memory information, and the faulty memory may be positioned according to the corresponding relationship between the memory and the abnormal data bits of the memory information, which is not described in this embodiment again.
It should be noted that three memory failure reasons are provided, but the present application is not limited to only detecting the three memory failure reasons, and the above is only a preferred embodiment, because the three memory failure reasons are enough to cover most of the memory failure scenarios, in practical application, a more detailed determination of the memory failure reasons may also be performed according to the memory information acquired by the BMC.
It should be further noted that the memory fault detection method provided by the present application needs to be applied to a server having a communication connection between the BMC and the BIOS, because the BMC and the BIOS do not have a communication connection directly used for transmitting memory information at present, and an Intelligent Platform Management Interface (IPMI) is used as an interactive standard Management specification that is conventionally used by a server system cluster, and can be used for implementing the BMC and other components. For example, the interaction of a BIOS/Unified Extensible Firmware Interface (UEFI), a CPU, and the like, monitors physical health characteristics of the server, such as temperature, voltage, fan operating state, power state, and the like, and implements server system cluster autonomy. Therefore, the communication connection of the memory information from the BIOS to the BMC is preferably realized through IPMI.
In addition, as for the fault information, the present application is not limited to the representation form of the fault information, and may be determined according to the corresponding implementation subject. For example, if the fault information is fed back to the operation and maintenance personnel through the LED lamp, the fault information should be a light signal or a control signal for controlling on and off of different LED lamps. Similarly, the fault information can also be a sound signal used by matching with a buzzer, and a text signal, an image signal and the like used by matching with a management platform, a mobile terminal and the like for unified management of the operation and maintenance personnel on the server.
According to the memory fault detection method provided by the application, the BMC can acquire the memory information of the BIOS through communication connection established in modes of IPMI and the like, and then positioning of a fault memory and determination of a memory fault reason are carried out according to the memory information.
Considering that in the existing server, a memory fault display lamp (i.e., an LED lamp) is disposed at each memory card slot, it is described that the optical signal prompt implemented by the LED lamp is easily accepted by those skilled in the art, and the fault memory is easily located while the implementation is simple and the cost is low, so this embodiment provides a possible implementation manner:
the memory fault lamps connected with the BMC are arranged at the memory card slots in groups respectively, each memory fault lamp of each group has at least three different colors and corresponds to different fault reasons respectively, in a possible application scene, one group of memory fault lamps has three different colors, wherein memory damage corresponds to a red LED lamp, the memory is not in place corresponds to a yellow LED lamp, and the memory is not trained and corresponds to a blue LED lamp.
Correspondingly, the step of returning corresponding fault information according to the fault memory and the fault reason comprises the following steps:
and controlling the memory fault lamps of the color corresponding to the memory fault reason in the memory fault lamp group corresponding to the fault memory to be always on.
It can be known from the above that, in this embodiment, the number of the memory fault display lamps arranged at each memory card slot is substantially expanded, each memory card slot corresponds to three different colors of memory fault display lamps (red, yellow, and blue), and different fault reasons (red-memory damage, yellow-memory absence, and blue-memory failure training) are visually displayed to the operation and maintenance staff through the on and off of the three different colors of LED lamps.
Therefore, in the application scenario of the present embodiment, the fault information is also different colors of light emitted by the different color LED lamps.
The mode that the LEDs with different colors are used for distinguishing different fault reasons of the memory has the advantages that the mode is visual and convenient, and operation and maintenance personnel can quickly locate the fault memory and determine the fault reasons only by checking the color and the position of the fault lamp of the memory which emits light.
However, the above method needs to modify the server to a certain extent, needs to increase the number of the memory fault lamps and add related circuits, and although the fault location and the reason display are very intuitive, the server is also changed greatly. Based on this, the present embodiment also provides another preferred scheme that utilizes the existing single memory failure lamp (i.e. the LED lamp, which is generally red, is disposed at the memory card slot when the memory fails):
as shown in fig. 2, the server includes: BIOS21, BMC22, fault location lamp module 23, and fault cause indicator lamp module 24;
the BIOS21 and the BMC22 are in communication connection through IPMI; the fault locating lamp module 23 is also an LED lamp arranged at each memory card slot in the existing server, is used for locating a fault memory, is connected with the BMC22, and is controlled by the BMC22 in an on-off state; the fault reason indicator lamp module 24 can be arranged at any position of the server, so that operation and maintenance personnel can conveniently check the fault reason indicator lamp module, at least three different colors (red: LED-R, yellow: LED-Y and blue: LED-B) exist, and the three colors respectively correspond to different fault reasons; the BMC22 is connected to each switch of the fault cause indicator module 24, and is configured to control the on/off of the switch, so that the fault cause indicator module 24 lights an LED lamp with a specified color to indicate a fault cause.
Based on the circuit structure shown in fig. 2, after the BMC22 determines the memory with the fault and the fault reason through the memory information acquired from the BIOS21, the fault location module 23 is controlled to light up the LED lamp disposed at the memory slot with the fault to perform fault location, and the fault reason indicator module 24 is controlled to light up the LED lamps (red, yellow, and blue) with the designated colors to indicate the fault reason of the current memory.
Compared with the scheme provided by the embodiment, the preferred scheme provided by the embodiment has the advantages that the change of the server is smaller, the implementation is easier, and the effect of intuitively and conveniently showing the current memory fault position and reason to operation and maintenance personnel can be still met.
The above two preferable schemes need to be expanded more or less to the LED lamp used by the existing server for displaying the memory fault, so this embodiment further provides a preferable scheme that the indication of the location of the faulty memory and the cause of the fault can be realized only by using the LED lamp arranged at each memory card slot in the existing server, including:
the step of returning corresponding fault information according to the fault memory and the fault reason comprises the following steps:
if the failure reason is that the memory is damaged, controlling a memory failure lamp corresponding to the failed memory to flash in a first flashing mode;
if the fault reason is that the memory is not in place, controlling a memory fault lamp corresponding to the fault memory to flash in a second flash mode;
if the fault reason is that the memory fails to pass the training, controlling a memory fault lamp corresponding to the fault memory to flash in a third flashing mode; wherein the first blinking manner, the second blinking manner, and the third blinking manner are different.
It is easy to know that the flashing mode can be any combination of different flashing states of the LEDs, such as different flashing frequencies, time for each flashing, and the like, and any number of different flashing modes can be obtained. In practical application, three appropriate and different flashing modes can be selected as the first flashing mode, the second flashing mode and the third flashing mode according to actual needs, the greater the difference of the three flashing modes is, the more the accuracy and timeliness of the fault reason can be obtained by operation and maintenance personnel, and the requirement for the operation and maintenance personnel to memorize the corresponding relationship between the different flashing modes and the fault reason is reduced.
In addition, the fault memory is positioned by the position of the memory card slot where the flickering LED lamp is positioned, which is the same as the existing scheme.
The advantages of a preferred scheme provided by the embodiment are as follows: the structure of the existing server does not need to be changed, the determination of the fault reason can be realized by utilizing the original fault display lamp, the realization is simple, meanwhile, the method is more favorable for being directly applied to the server which is delivered from a factory or put into use, and the universality of the method is improved.
In practical applications, after a specific memory failure cause is determined and returned by the memory failure detection method disclosed in the embodiment, application scenarios may occur, such as that an operation and maintenance worker is not near a server and that the operation and maintenance worker subsequently has an analysis requirement on the overall working condition of the server for a period of time, and the embodiment provides a preferred implementation scheme for the problems faced by the application scenarios, and as shown in fig. 3, the method further includes:
s14: and when the fault memory is judged to exist, sending the corresponding memory information to the memory for storage.
According to the embodiment, the reason for determining the memory fault according to the memory information is mainly determined according to the information on the specific data bit, so that after the memory fault is determined, the information on the corresponding specific data bit can be copied and sent to the memory for storage, and preferably, the information such as the positioning information and the fault time can be matched, so that operation and maintenance personnel can better and conveniently perform subsequent calling for server memory fault analysis.
Further, on the basis of the foregoing example, this example further provides a preferred implementation, and the step S14 further specifically includes:
s14-a: and if the fault reason corresponding to the fault memory is that the memory is damaged, storing the memory information into the first memory.
S14-b: and if the failure reason corresponding to the failure memory is that the memory is not in place, storing the memory information into the second memory.
S14-c: and if the fault reason corresponding to the fault memory is that the memory is not trained, storing the memory information into a third memory.
The first storage, the second storage and the third storage are different, namely, the memory information corresponding to different failure reasons is stored separately, and when operation and maintenance personnel need to perform failure analysis, the memory information of the specified type can be obtained quickly.
In addition, for the three storages, the operation and maintenance personnel can also quickly locate the storages by arranging the LED lamps and adopting the same expression form as that of different internal storage fault operations.
Illustratively, a red LED lamp is disposed at the first storage, a yellow LED lamp is disposed at the second storage, and a blue LED lamp is disposed at the third storage. Or the LED lamp arranged at the first storage flickers in a first flickering mode, the LED lamp arranged at the second storage flickers in a second flickering mode, and the LED lamp arranged at the third storage flickers in a third flickering mode.
In addition, the memory information corresponding to the failed memory is retained through the preferred scheme disclosed by the embodiment so as to be called by subsequent operation and maintenance personnel for analysis.
Therefore, on the basis of the above embodiment, the memory information stored in the memory can be deleted according to a certain rule by setting the data clearing logic, and the memory resource can be released in time.
It is easy to know that after the memory is accessed and called by an operation and maintenance person through external equipment, the memory information is obtained and can be regarded as overdue data, and further, the memory data can be deleted as a cleaning logic to release the memory space, so that the subsequently generated fault memory information can be conveniently stored, the release of the storage resource of the memory is ensured to a certain extent, and the memory is beneficial to providing a storage function for a long time.
In addition, in another possible implementation, the memory information whose storage time exceeds the preset threshold may also be regarded as the expired data, and the deletion operation performed on the memory information releases the storage space of the memory.
Further, in the above embodiment, when the external device accesses the memory, it is preferable to perform authentication on the external device that sends the access request, so as to avoid the problem of false deletion caused by the above-mentioned cleaning logic for deleting the accessed memory information while ensuring data security.
In this embodiment, the implementation manner of the identity verification is not limited, and the trusted external device should hold the pre-assigned identity token and perform the identity verification before accessing the storage, generally speaking, only the trusted faulty device that is actually calling the memory information may pass the identity verification, so that the security of the memory information stored in the storage is ensured, and the data is prevented from being deleted by mistake due to access of other devices.
According to the preferred scheme provided by the embodiment, the memory information corresponding to the fault memory is sent to the memory to be stored, so that operation and maintenance personnel can analyze the memory fault and manage the server conveniently. Furthermore, the memory information is separately stored according to different fault reasons, so that operation and maintenance personnel can conveniently obtain the required memory information. In addition, after the operation and maintenance personnel access the memory information stored in the memory through the external equipment, the expired data can be cleared, the storage space is released, and the persistent application of the memory is facilitated. Meanwhile, in order to ensure the safety of data, the safety verification is carried out on external equipment for accessing the memory, and the memory information in the memory can be accessed only through the verified equipment, so that the safety is ensured, and the mistaken deletion of the memory information is avoided.
To more clearly and specifically describe the memory failure detection method provided in the present application, the following description is further made with reference to an example and the circuit structure shown in fig. 2, where the method is shown in fig. 4 and includes:
s41: and the BIOS performs self-checking to acquire the memory information of the server.
S42: the BMC acquires the memory information of the BIOS through the IPMI.
S43: and the BMC positions the fault memory according to the memory information and controls the fault positioning lamp module to light up the LED lamp corresponding to the fault memory.
S44: the BMC determines whether the memory is damaged according to the memory information, and if so, goes to step S45.
S45: the BMC controls the fault reason indicator lamp module to light a red lamp.
