Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of a storage medium detection method applied to a BMC according to an embodiment of the present invention, where the method includes the following steps:
s101, writing the detection value into a target register in the storage medium.
The storage medium may be any one of common storage media with read and write functions, such as an EEPROM.
The target register may be a register in the storage medium, to which an inherent function is not specified.
The BMC is in communication connection with the storage medium through I2C. The I2C (Inter-Integrated Circuit) bus is a two-wire serial bus, and can be used to connect the microcontroller and its peripheral devices.
The BMC may write the detection value to the target register in the storage medium, specifically via I2C. Specifically, the BMC may send I2C a request to access the storage medium to write a detection value in the target register.
The detection value may be predefined (for example, the detection value may be defined as AAh or 55h), or may be determined at any time (for example, a random function is used to randomly generate a latest detection value of the number of bytes of length that can be stored in a target register). It should be noted that, while the detection value is written into the target register, the detection value needs to be recorded so as to verify whether the read/write function of the storage medium is abnormal or not.
Preferably, it is considered that in practical applications, the storage medium may be periodically tested to find the abnormality in time. If the same detection value is used for a long time, there is a possibility that the failure of the storage medium cannot be detected when the target register cannot be written and the read function is normal. Therefore, in practical applications, it is also possible to periodically update the detection value and write the detection value to the target register. Therefore, the condition of abnormity of the target register caused by the fact that the target register cannot be written can be found at the first time. The period for updating the detection value may be the same as or different from the period for detecting the storage medium, and specifically, the detection value may be changed every time the detection is performed, or may be changed after the detection is performed for a plurality of times.
And S102, reading a register value corresponding to the current moment of the target register.
After writing the detection value to the target register, the register value in the target register may be read.
Specifically, the BMC establishes a communication connection with the storage medium through I2C, that is, the register value can be read through I2C. For example, the BMC sends I2C to request access to the storage medium, and reads the register value corresponding to the current time of the target register.
S103, judging whether the register value is the same as the detection value.
After reading the register value, judging whether the register value is the same as the detection value, if so, indicating that the read-write function of the storage medium is normal; if the difference is not the same, the reading function and the writing function of the storage medium have at least one functional abnormity. That is, when the write function of the storage medium is abnormal, a write failure or a write value error may occur when a detection value is written into the register, and even when the read function is normal, the register value read is different from the detection value; when the reading function of the storage medium is abnormal, a detection value is normally written into the target register, and when the reading function is abnormal, reading failure may occur, and the read value is different from the real value in the target register, so that the read register value is different from the detection value; when both the read function and the write function of the storage medium are abnormal, it is almost impossible for the detected value and the read register value to be the same, and therefore, when both the read function and the write function are abnormal, the detected value and the register value may be regarded as being impossible to be the same.
After determining the judgment result whether the register value is the same as the detection value, the storage medium detection result can be obtained according to different judgment results. Specifically, if the determination result is yes, step S104 is executed; if the determination result is no, step S105 is executed.
And S104, determining that the storage medium passes the detection.
When the detection value is consistent with the register value, the reading function and the writing function of the storage medium can be determined to be normal, and at the moment, the storage medium can be directly determined to be normal, namely the storage medium passes the detection at this time. When the storage medium is determined to be normal, the storage medium can be continuously used for storing the key data, and the BMC can also continuously read the valid information from the storage medium.
And S105, determining that the storage medium fails to be detected, and outputting alarm information.
When the detection value is inconsistent with the register value, it can be determined that at least one of the read function and the write function of the storage medium is abnormal, at this time, the storage medium is no longer suitable for continuously storing important data, and the BMC continuously accessing the storage medium may cause serious abnormality of the BMC. At the moment, the detection and identification of the storage medium can be determined, in order to ensure that important data can be effectively stored, the BMC can perform data interaction with a normal storage medium and can output alarm information, so that a user can timely know that the currently used storage medium is abnormal. When a user acquires alarm information, the important data can be normally stored by replacing a storage medium or a mainboard, the normal work of the BMC is guaranteed, and the system performance is maintained to be stable.
Wherein, outputting the alarm information may specifically include, in practical application: and outputting alarm prompt information by using the corresponding warning device of the BMC, and/or sending alarm notification information to the user terminal. Wherein, the warning device can be embodied as an optical alarm such as an LED alarm lamp, an acoustic alarm such as a buzzer, and an audible and visual alarm. The user terminal may be specifically a smart phone, a computer, or a device or software (e.g., a mailbox client) capable of remotely receiving the alarm feature.
Preferably, considering that in practical applications, there may be a case where read-write abnormality occurs in only one register in the storage medium, therefore, it may be determined that misdetermination may occur based on only the read-write performance of the same register. To solve this problem, in practical applications, at least one of the following two processing methods can be adopted:
mode 1: a plurality of registers may be specified in the storage medium as target registers, and when detecting the storage medium, step S101 may specifically be: writing the detection values to a plurality of target registers in the storage medium;
accordingly, the determining of the storage medium detection failure in step S105 includes:
and determining that the storage medium detection fails after determining that the register values read from the plurality of target registers are different from the detection values.
That is, when checking whether the storage medium is abnormal, it is possible to determine whether the storage medium is abnormal by writing the detection values into a plurality of target registers in the storage medium and reading the register values in the target registers. Specifically, when the register values read by all the target registers are inconsistent with the detection values, it is determined that the storage medium is abnormal. Of course, whether the storage medium is abnormal or not can be determined in a manner of setting whether the proportion or the number of the target registers with the abnormal condition exceeds the corresponding threshold value or not.
Mode 2: a plurality of target registers can be arranged, but one target register is replaced when each detection is carried out, so that larger errors of detection results caused by the contingency of a single target register can be reduced. Specifically, step S101 may specifically include:
step one, determining a target register from a plurality of designated registers in a storage medium;
and step two, writing the detection value into the target register.
For convenience of description, the above two steps will be described in combination.
The designated register may be predetermined, and the target register determined from the plurality of designated registers may be determined randomly or in a designated rotation order. After a target register is identified from the plurality of designated registers, the detection value may be written to the target register.
The method provided by the embodiment of the invention is applied to BMC, and the detection value is written into the target register in the storage medium; reading a register value corresponding to the current moment of a target register; judging whether the register value is the same as the detection value; if so, determining that the storage medium passes the detection; if not, determining that the storage medium detection fails and outputting alarm information.
Considering a storage medium as a storage medium, reading and writing are key operations that enable stored data. Therefore, whether the storage medium is abnormal or not can be detected, and both reading and writing operations can be started. Based on this, in the method, the BMC writes the detection value into the target register in the storage medium and then reads the register value in the target register. When the read register value is consistent with the written detection value, the read-write function of the storage medium is normal, if the read register value is inconsistent with the written detection value, at least one function of the read function and the write function of the storage medium can be determined to have a problem, at this moment, the storage medium can be judged to be abnormal, namely, the storage medium is failed to be detected, and at this moment, alarm information can be output. When the storage medium is specifically an EEPROM, a user can know that the EEPROM is abnormal, and then the EEPROM or a mainboard is replaced, so that the normal data interaction between the BMC and the EEPROM can be ensured, and the EEPROM can store important data.
It should be noted that, based on the above embodiments, the embodiments of the present invention also provide corresponding improvements. In the preferred/improved embodiment, the same steps as those in the above embodiment or corresponding steps may be referred to each other, and corresponding advantageous effects may also be referred to each other, which are not described in detail in the preferred/improved embodiment herein.
Preferably, in order to avoid transient failure of the storage medium or single read-write failure due to instability of the I2C link, a method of retrying for multiple times can be adopted to avoid false alarm caused by single point failure, thereby avoiding causing trouble to clients. The specific implementation process comprises the following steps:
in the step S105, the following steps may be specifically performed:
step one, determining that a storage medium has one-time read-write abnormity, wherein the retry number is + 1;
step two, when the retry number is 0, finishing the detection;
step three, when the retry number is not 0, judging whether the retry number is larger than a preset threshold value;
step four, if yes, determining that the storage medium detection fails;
step five, if not, repeatedly executing the step of writing the detection value into the target register in the storage medium;
accordingly, when the storage medium is determined to pass the detection, the retry times are cleared.
For convenience of description, the above steps will be described in combination.
In the present embodiment, a counter is provided for counting the number of consecutive detection failures, i.e., the number of retries, and the initial value of the number of retries may be set to 0.
After determining that the storage medium has one read-write abnormality, adding 1 to the retry number; when the detection is passed, resetting the retry times, after a result is obtained by one detection, judging whether the retry times is greater than a preset threshold value, if so, indicating that the times of the storage medium detection abnormity reach the condition of judging the storage medium abnormity, and at the moment, directly determining that the storage medium detection fails; if not, repeating the operation of step S101; if the retry number is 0, the detection can be ended and the detection is determined to pass.
It should be noted that, in practical applications, the first embodiment and the preferred embodiment may be fused according to practical application requirements, and in order to facilitate those skilled in the art to understand how to implement practical applications and how to combine the preferred embodiments, the following describes the storage medium detection method in detail with reference to a specific application scenario as an example.
And writing AAh or 55h into the EEPROM target register by the BMC, reading the register, comparing whether the read value is the write value, if so, passing the detection, and continuously writing 55h or AAh at an interval of 1 hour. If the single detection fails, 10 retries can be performed, if 10 fails, an alarm is given, please refer to fig. 2 for a specific implementation flow, fig. 2 is a specific application schematic diagram of an EEPROM detection method in an embodiment of the present invention, and the implementation process includes:
step 1, initializing a detection value to AAh when the BMC starts to detect the EEPROM;
step 2, judging whether the detection value is AAh;
step 3, if yes, setting the detection value to be 55 h;
step 4, if not, setting the detection value as AAh;
step 5, sending an I2C request to access the EEPROM, and writing a detection value into a target register;
step 6, sending an I2C request to access the EEPROM, and reading a register value in a target register;
step 7, judging whether the register value is equal to the detection value;
and 8, if so, clearing the retry times, terminating the detection of the current round and determining that the detection of the current round passes.
Step 9, if not, the detection fails, and the retry number is + 1;
step 10, judging whether the retry number is more than 10;
and 11, if so, terminating the detection of the current round, determining that the detection of the current round fails, and recording a detection log.
Wherein, each round of detection can comprise one detection or a plurality of detections, and the condition for terminating each round of detection can be specifically as follows: within 10 repeated detections, the last detection is detection pass, and all the 10 repeated detections fail.
From the above steps, by applying the EEPROM detection method provided by the embodiment of the present invention, whether the EEPROM can be read or written normally by the BMC can be determined by actively erasing and reading the self-check register every 1 hour, which has the advantage that the whole detection process has no influence on the normal operation of the BMC, and can also verify whether the communication between the BMC and the EEPROM is normal most directly.
In order to avoid instant failure of EEPROM or single read-write failure caused by instability of I2C link, the invention adopts a method of retrying for a plurality of times to avoid false alarm caused by single point failure, thereby avoiding causing trouble to clients.
The method provides a realization method for automatically detecting whether the EEPROM is normally available by the BMC. The invention monitors the health state of the EEPROM in real time by actively reading and writing the EEPROM without influencing the normal work of the BMC, informs the abnormal condition of the EEPROM to a user in time, avoids false alarm caused by single-point fault by retry, and avoids loss of important data of the BMC or abnormal operation.
