When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of the present application, first information may also be called second information, and similarly, second information may also be called first information. Depending on the context, the word "if" as used herein may be interpreted as "at" or "when" or "in response to a determination."

In existing electronic equipment, the storage medium can usually be detected according to indicators such as read and write response time and temperature. If a certain indicator of the storage medium is detected to exceed the preset standard range, it is considered that the storage medium is abnormal and an alarm is issued.

However, there are still some problems with this detection method. On the one hand, the existing detection indicators such as reading and writing time and temperature are relatively one-sided and cannot fully reflect the health status of the storage medium; It takes a long time, etc., but it is not possible to combine multiple detection indicators of the storage medium to make a comprehensive evaluation, so that the user cannot perform targeted processing on the storage medium according to the comprehensive evaluation situation.

In view of this, an embodiment of the present invention provides a storage medium detection method.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a method for detecting a storage medium according to an exemplary embodiment of the present application. As shown in Figure 1, the process may include the following steps:

Step S101: Receive a detection request for the storage medium; determine the parameter value of the storage medium corresponding to each detection index according to each detection index in the detection request; the detection index includes at least: the use of the storage medium , and/or slot connections of the storage medium, and/or recorded historical events that occurred on the storage medium.

In this embodiment, the storage medium may be a component used to store data in an electronic device, such as a hard disk, a floppy disk, and the like. Wherein, the electronic device may be a server, a PC, a mobile terminal, etc., and the electronic device may include one or more storage media, which is not limited in this embodiment.

In this embodiment, the storage medium may be detected through the electronic device where the storage medium is located. For example, in response to a detection request issued by the user, the electronic device detects the storage medium indicated by the detection request.

In this embodiment, the detection request may be performed periodically. For example, the detection request issued by the user may include a detection period, such as 1 day, 1 week, etc., and the electronic device detects the storage medium every time a detection period passes after receiving the request.

In this embodiment, the detection request may include a designated storage medium to be detected and a detection indicator.

In one embodiment, the storage medium to be detected and the detection index can be determined by the user's own choice, for example, the user can select the storage medium to be detected and the detection index to be detected through the visual interface of the electronic device.

In this embodiment, the detection index is an index that can be used to evaluate the health status of the storage medium. In an example, the detection index in the detection request includes at least one of the following: usage of the storage medium, connection of slots of the storage medium, and recorded historical events of the storage medium.

The above-mentioned detection indicators are introduced in detail below.

Usage of the storage medium: refers to the usage of the storage medium during system operation, including performance parameters, etc., which can be viewed through the software system of the electronic device where the storage medium is located. For example, it may be one or more of the following multiple indicators: drive timeout period, disk kick times, repair times, read and write timeout times, and the like.

The slot link status of the storage medium: refers to the status of the link connecting the storage medium and the electronic device. Optionally, it can be indicated according to the number of link abnormalities in the slot where the storage medium is located. It should be noted that since the slots in the electronic device are connected to the hard disks one by one through physical interfaces, internal connecting wires, etc., the number of communication errors of the slots can be detected by the electronic device to represent the number of link abnormalities of the slots.

Recorded historical events occurring in the storage medium: refer to events occurring in the storage medium. Wherein, the event that occurs may be every event that occurs inside the storage medium, or may also be an event preset for the storage medium. The preset event is determined according to different application scenarios. For example, the preset event may be the migration of the storage medium.

In this embodiment, on the basis of basic detection indicators such as reading and writing time and temperature, multiple detection indicators are added, and the detection indicators can be selected according to the actual situation of the storage medium. The embodiment of the present application can detect the storage medium more comprehensively, cover as many causes of abnormalities as possible, and reflect the health status of the storage medium more comprehensively.

In an example, the detection indicator may also include other indicators, for example, it may include attributes of the hard disk itself, comprehensive detection results, and the like.

Wherein, the property of the hard disk itself refers to the inherent property of the hard disk, which can be obtained by reading the sensor in the hard disk and the set firmware program counter. For example, it may be one or more of the following multiple indicators: hard disk cache size, rotational speed, hard disk capacity, hard disk temperature, power-on time, impact vibration, soft and hard reset.

Comprehensive testing results refer to hard disk parameters detected by a dedicated comprehensive testing tool. The comprehensive testing tool is generally a software program corresponding to the type of hard disk. Electronic equipment can load the comprehensive testing tool and then test the disk by executing the software program. . Optionally, the following detection indicators are included: hard disk vibration parameters, hard disk head rotation offset parameters, and hard disk disk surface rotation offset parameters.

It should be noted that, for different storage media, different detection indicators may be included, and for the same detection indicator, different detection methods may also be used, and this is only an illustration, not a specific limitation.

In this embodiment, for each detection index included in the detection request, the parameter value of the storage medium corresponding to each detection index may be determined respectively. The detection index is different, and the method of determining the parameter value is generally different.

In one embodiment, for the parameter value of the quantity category, such as "number of times", the accumulated quantity within the preset time period can be used as the parameter value, wherein, optionally, the preset time period can be from the last detection to this time The period of detection. For example, if the detection index is the number of read and write timeouts in the usage of the storage medium, it can be queried in the software system where the storage medium is located to determine the number of read and write timeouts of the storage medium since the last detection.

In one embodiment, for non-quantitative parameter values, such as "timeout time", "whether a preset event occurs", etc., the currently detected result may be used as the parameter value.

Of course, the description here is only an example. For different detection indicators, the corresponding parameter values can be determined according to the actual situation, and will not be repeated here.

Step S102: According to the parameter value of the storage medium corresponding to each detection index, determine the quantitative information of the storage medium corresponding to each detection index on the detection index.

In this embodiment, the quantitative information corresponding to each detection index can be determined according to the parameter value of the storage medium corresponding to each detection index. Wherein, the quantitative information may indicate the health status of the storage medium on the detection index. For example, quantitative information can be regarded as a score. The higher the score, the healthier the storage medium is on the detection index, and the lower the probability of abnormality.

In this embodiment, the quantitative information of the medium on various detection indicators can be stored through the method shown in FIG. 2 . As shown in Figure 2, it includes the following steps:

Step S1021: For each detection index, obtain the set quantification standard corresponding to the detection index; the quantization standard includes at least the corresponding relationship between the storage medium parameter value corresponding to the detection index and the quantification information.

In this embodiment, each detection indicator may correspond to the same or different quantification standards. Wherein, the quantification standard corresponding to each detection index at least includes the corresponding relationship between the storage medium parameter value corresponding to the detection index and the quantification information.

In an example, the quantization standard may be a standardized calculation method, which may perform standardized calculation on the parameter value of the storage medium, and then determine the quantification information corresponding to the parameter value. For example, the calculation method may be to perform normalized calculation on parameter values.

In an example, the quantization standard may include several parameter value ranges, and each parameter value range corresponds to a piece of quantization information. For example, if the parameter value belongs to the first range, it corresponds to the first quantization information; if the parameter value belongs to the second range, it corresponds to the second quantization information. Thus, quantization information corresponding to each parameter value can be determined.

Of course, the quantitative standard can also indicate the corresponding relationship between the parameter value and the quantitative information in other ways. For example, for the recorded historical events of the storage medium, the parameter value can be an event number, and each event number can be preset Corresponding quantitative information, etc. The description here is only for illustration and not for limitation.

Step S1022: Find the quantitative information corresponding to the determined storage medium parameter value corresponding to the detection index in the quantitative standard, and determine the found quantitative information as the quantitative information of the storage medium corresponding to the detection index.

In this embodiment, for each detection index, the quantitative information corresponding to the parameter value may be searched in the quantization standard according to the quantization standard of the detection index. Furthermore, the quantitative information can be used as the quantitative information of the storage medium on the detection index.

In this embodiment, each detection index may include several sub-detection indexes, such as the detection index of the usage of the storage medium, which may include multiple specific sub-indexes such as drive timeout time, number of kick disks, number of repairs, number of read and write timeouts, etc. index. For each detection index, the corresponding quantitative information can be determined for each sub-detection index respectively, and then the quantitative information of multiple sub-detection indexes can be integrated to obtain the quantitative information corresponding to the detection index.

In this embodiment, the parameter value can be a specific quantity. For example, the detection indicator is the usage of the storage medium. Taking the usage of the storage medium as the number of read and write timeouts as an example, the quantification standard can be the corresponding relationship between the number of times and the quantification information. For example, 5 reading and writing timeouts correspond to 100 quantization information, and 50 reading and writing timeouts correspond to 0 quantization information.

In this embodiment, the parameter value may also be a ratio, for example, it may be a ratio that deviates from a rated attribute. For example, the detection index is the reading and writing time, and the quantitative standard may be the corresponding relationship between the ratio of the reading and writing time exceeding the rated time and the quantitative information. For example, less than 0% of the rated time corresponds to 100 quantization information, 20% of the rated time exceeds the corresponding quantization information of 70, and so on.

Certainly, the parameter value may also be in other forms, which are only illustrated here and not limited.

For example, the quantization standard may indicate the correspondence between the parameter value and the quantization information through the correspondence between the parameter value range and the quantization information. For each detection index, first obtain the quantification standard corresponding to the detection index, for example, including the corresponding relationship between three groups of parameter value ranges and quantitative information, as shown in Table 1; then, determine the parameters of the storage medium corresponding to the detection index value, for example, the parameter value 5; then, in the quantization standard, search for the quantification information corresponding to the parameter value range to which the parameter value belongs, for example, in

In Table 1, it can be determined that the quantization information corresponding to the parameter value 5 is 100.

parameter value quantitative information 0-10 100 11-30 60 >30 0

Table 1

Step S103: Determine the health index of the storage medium based on the quantitative information of the storage medium on each detection index corresponding to each detection index, and determine the health index of the storage medium when the health index is less than or equal to the set health index threshold. The storage medium is abnormal.

In this embodiment, based on the quantitative information of the storage medium corresponding to each detection indicator on each detection indicator, the health index of the storage medium can be obtained by integrating all the quantitative information.

In one embodiment, the sum or average of the quantitative information on each detection index can be used as the health index.

In another embodiment, the weight value of each detection index can be determined first, and then the health index of the storage medium can be determined based on the quantitative information of the storage medium on each detection index and the weight value of each detection index .

For example, the product of the weight value of each detection index and the quantitative information of the storage medium on the detection index can be calculated separately, and then the products obtained on each detection index can be added, and the sum obtained can be used as the health of the storage medium index.

For example, the usage status of the storage medium, the slot connection status of the storage medium, and the recorded historical events of the storage medium may be used as detection indicators. For the usage of the storage medium, assume that the weight value of the detection index is 30%, and the quantitative information of the storage medium is 100; for the slot connection of the storage medium, assume that the weight value of the detection index is 50%, The quantitative information of the storage medium is 60; for the recorded historical events of the storage medium, assuming that the weight value of the detection indicator is 20%, and the quantitative information of the storage medium is 60, the formula 100*30% can be used +60*50%+60*20%, the health index of the storage medium is determined to be 72.

In this embodiment, the health index may indicate the health state of the storage medium. Generally speaking, the higher the health index, the healthier the storage medium and the lower the probability of abnormalities. In an embodiment, a health index threshold may be preset, and when the health index is less than or equal to the set health index threshold, it is determined that the storage medium is abnormal. Based on this, the user can intuitively obtain the current state of the storage medium and process it in time.

So far, the embodiment shown in FIG. 1 is completed. According to the embodiment shown in FIG. 1, a detection request for a storage medium is received, wherein the detection index indicated by the detection request includes: the use of the storage medium, and/or the slot connection of the storage medium, and/or Recorded historical events that occurred on the storage medium. After receiving the detection request, first determine the parameter value of the storage medium corresponding to each detection index, and then determine the quantitative information of the storage medium corresponding to each detection index according to the parameter value of the storage medium corresponding to each detection index, and then according to each The quantitative information of the storage medium corresponding to the detection index is determined to determine the health index of the storage medium. Therefore, on the one hand, on the basis of basic detection indicators such as reading and writing time and temperature, this embodiment adds a number of detection indicators, which can be selected according to the actual situation of the storage medium, and can more comprehensively monitor the storage medium. On the other hand, this embodiment does not evaluate each indicator individually, but combines multiple detection indicators to obtain a health index, and then the user can intuitively determine whether the storage medium is currently abnormal according to the health index , and deal with it in a timely manner.

In this embodiment, based on the health index obtained by detecting the storage medium, the change trend of the health index of the storage medium may also be determined. A method for determining the changing trend of the health index will be introduced below in conjunction with FIG. 3 .

Fig. 3 is a schematic flowchart of another storage medium detection method shown in an exemplary embodiment of the present application. As shown in Figure 3, the following steps are included:

Step S301: Determine the change trend of the health index of the storage medium according to the currently determined health index and the stored previously determined historical health index; the change trend of the health index indicates that the health index increases, decreases or remains unchanged.

Step S302: If the health index trend indicates that the health index is declining, it is determined that there is a potential abnormality in the storage medium.

In this embodiment, the system where the storage medium is located may store the health index after detecting the health index.

Optionally, the storage medium may be tested periodically, for example, once every 2 hours, and then store the health index obtained through the detection.

Optionally, the storage medium may periodically delete the stored health index, for example, delete the health index detected before a preset period of time from the current time every week or every month.

In this embodiment, the change trend of the health index of the storage medium may be determined according to the health index determined by the current detection and the stored historical health index determined before.

Among them, the previously determined historical health indexes that have been stored can be all the historical health indexes of the storage medium stored in the system; Obtain the historical health index of the specified quantity from far away; or it can also be the historical health index within the specified time period.

Based on the plurality of health indices, a change trend of the health indices of the storage medium may be determined, indicating that the health indices increase, decrease, or remain unchanged.

In this embodiment, it may be determined whether there is a potential abnormality in the storage medium according to the change trend of the health index. For example, if the change trend of the health index indicates that the health index drops, it is determined that there is a potential abnormality in the storage medium.

Wherein, optionally, the change of the health index of the storage medium may also be predicted according to the change trend of the health index, for example, the time when the change of the health index is less than a preset threshold may be determined, and then a prompt is given to the user.

In this embodiment, the variation trend of the health index can be determined by fitting a curve.

Firstly, fitting the currently determined health index and the stored previously determined historical health index in chronological order to obtain a fitting curve of the health index; then determining the health of the storage medium based on the fitting curve Exponential trend.

As shown in Figure 4, the horizontal axis is time, and the vertical axis is health index. Taking the health index detected from January 1 to January 7, 2020 as an example, the 7 health indexes detected and determined within the 7 days are fitted, and the fitting curve shown in Figure 4 can be obtained.

It should be noted that there are many ways of data fitting, for example, polynomial function fitting can be performed by Matlab software, which will not be repeated here.

In this embodiment, according to the fitting curve, the health index trend of the storage medium can be determined.

In this embodiment, the trend of the health index can be determined according to the slope of the tangent line corresponding to the fitted curve at the current moment. For example, the tangent slope of the point corresponding to the current moment can be measured in the fitting curve; or the fitting function corresponding to the fitting curve can be derived to determine the derivative value corresponding to the current moment.

If the slope of the tangent line is positive, it is determined that the change trend of the health index is rising; if the slope of the tangent line is 0, it is determined that the change trend of the health index is constant; if the slope of the tangent line is negative, it is determined that the change trend of the health index is healthy Index down.

Thus, the health index change trend can be determined according to the slope of the tangent line. If the health index trend indicates that the health index declines, it is determined that there is a potential abnormality in the storage medium, and a warning can be given to the user.

In one example, the numerical change of the health index of the storage medium can be predicted according to the slope of the tangent line. For example, the predicted health index of each subsequent day is calculated according to the slope of the tangent line.

In an example, a hidden danger threshold may be preset, and if the predicted health index calculated and determined according to the tangent slope is smaller than the hidden danger threshold, it is predicted that the storage medium will enter a hidden danger state at this time. Thus, the storage medium can initiate a prompt to the user, prompting the user when the storage medium enters the hidden state.

So far, the embodiment shown in FIG. 3 is completed. Through the embodiment shown in FIG. 3 , the change trend of the health index of the storage medium can be predicted according to the fitting curve, so that the user can be prompted in advance to avoid abnormal data caused by damage to the storage medium.

In this embodiment, in order to enable the user to better understand the specific conditions of the storage medium, a detection report may be generated according to the parameter values of the storage medium corresponding to each detection index and/or the health index of the storage medium. Optionally, the detection report may be displayed to the user through a visual interface or other means.

In this embodiment, it is also possible to generate corresponding prompt information according to the quantitative information of each detection index, and add the prompt information to the detection report, so that the user can handle the abnormal event according to the prompt information. For example, if the temperature of the storage medium is abnormal, the user can be reminded to check the ventilation and adjust the ambient temperature through prompt information; If the specified range is exceeded, a prompt message can be used to remind the user that the storage medium may have exceeded the warranty period and needs to be replaced in time.

In this embodiment, in order to better save the detection results of the storage medium, a preset reserved area can also be set in the storage area of the storage medium, and the data stored in the preset reserved area is formatted in the storage medium will not be deleted.

In an example, the health index of the storage medium may be stored in a preset reserved area of the storage medium, and/or, the parameter values of the storage medium corresponding to the determined detection indicators or the corresponding detection indicators Quantified information of the storage medium.

In an example, the generated detection report may be stored in a preset reserved area of the storage medium.

Therefore, storing the detection results in the preset reserved area can make the detection results of the storage medium follow the storage medium. Even if the storage medium is migrated, the new electronic device can still obtain complete record, so that the user can effectively manage the storage medium according to the detection result.
