Detailed ways

In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

See Figures 1 to 6. It should be noted that the diagrams provided in this embodiment are only to illustrate the basic concept of the present invention in a schematic way, so the diagrams only show the components related to the present invention rather than the number, shape and the number of components in the actual implementation. For dimension drawing, the type, quantity and proportion of each component can be changed at will in actual implementation, and the component layout may also be more complicated.

Referring to FIG. 1 , it is a schematic flowchart of a method for refreshing hard disk firmware according to an embodiment of the present invention. As shown in Figure 1, the method includes the following steps:

Step S101: Acquire hard disk information of all hard disks in the storage system.

During specific implementation, the hard disk information of all hard disks in the storage system can be acquired through the control instruction. In an exemplary embodiment, the hard disk information can be acquired using the control instruction of "fdisk -1". The hard disk information may include hard disk identifiers, hard disk capacities, sector numbers, sector capacities, magnetic column numbers, and magnetic column capacities of all hard disks in the storage system.

Moreover, the hard disk information includes a plurality of information lines. In an exemplary embodiment, the hard disk information includes a first information row and a second information row; wherein, the first information row is represented as "Disk /dev/sdb: 27000.3GB, 27000311906304 bytes", which is used to represent the hard disk identification. The hard disk capacity of "/dev/sdb" is 27000.3GB, 27000311906304 bytes; the second information line is expressed as "Units = sectors of 1 * 512 = 512bytes", and the sector capacity is 512bytes.

Each line of information further includes a plurality of blocks of information, separated by spaces. For example, the above-mentioned first information row may include 5 information blocks, specifically "Disk", "/dev/sdb:", "27000.3GB,", "27000311906304", and "bytes".

In this embodiment of the present invention, the following steps will be described in detail by taking the hard disk information including the first information row and the second information row as an example.

Of course, it should be noted that the above-mentioned way of obtaining the hard disk information is only an exemplary embodiment. During the specific implementation, the hard disk information of all the hard disks in the storage system can be obtained through other command tools; moreover, the organization form of the hard disk information Nor is it limited to the description of the above-mentioned embodiments.

Step S102: Extract the hard disk identifier from the hard disk information to form a first list.

In the embodiment of the present invention, all hard disk identifiers are extracted from the hard disk information according to the keywords, and the extracted hard disk identifiers are formed into a first list.

Referring to FIG. 2 , it is a schematic flowchart of a method for extracting a hard disk identifier according to an embodiment of the present invention. As shown in Figure 2, the method includes:

Step S1021: Extract the information row with the first keyword from the hard disk information.

According to the hard disk information obtained in step S101, since the information row where the hard disk identification is located has the same repeated characters. According to the exemplary hard disk information in step S101, the repeated characters may include "Disk" and "/dev/sd".

In the first implementation case, any one of the above-mentioned repeated characters can be used as the first keyword, so as to extract the information row where the first keyword is located. In an exemplary implementation, the "sed" command can be used to extract the information line with the first keyword, and the corresponding regular expression is generated according to the first keyword as "/Disk" or "\/dev\/sd/p", Through the combination of the "sed" command and the regular expression, the information line where the first keyword is located can be extracted.

In the second implementation case, the combination of the above repeated characters can be used as the first keyword, so as to extract the information line where the first keyword is located. In another exemplary embodiment, the regular expression generated according to the first keyword may be "/Disk\ \/dev\/sd/p", so that through the combination of the "sed" command and the regular expression, the The information line where the first keyword is located.

Through the first keyword, the extracted information row is the first information row, namely "Disk /dev/sdb: 27000.3GB, 27000311906304 bytes".

Step S1022: Delete the information row with the second keyword from the extracted information row.

Since the extracted information lines may include unnecessary information lines, such as information lines including "sda", "sda" usually represents the system disk rather than the hard disk that needs to be refreshed. Filter, remove unneeded lines of information. In an exemplary embodiment, in order to delete the information row containing "sda", "sda" may be used as the second keyword, and the information row with the second keyword can be deleted by calling the "sed" command.

Step S1023 : extract information blocks at fixed positions from the remaining information rows after deletion, respectively, to obtain a hard disk identifier.

In an exemplary embodiment, after step S1022, the remaining information row is the first information row. In the first information row, the information block in the second position is the identification of the hard disk to be extracted. During specific implementation, the hard disk identifier can be extracted by calling the "awk" command and formulating an information block for extracting the second position. After the processing in step S1023, the information block "/dev/sdb:" located at the second position can be extracted from the first information row, and the information block can be used as a hard disk identifier for processing in subsequent steps.

Of course, it should be noted that the above process of extracting information lines is only an exemplary embodiment, and during specific implementation, any other command or regular expression in any other form may be used, which is not limited in this embodiment of the present invention.

In order to obtain a hard disk identifier in a standard format, the embodiment of the present invention further provides another method for extracting a hard disk identifier. On the basis of the extraction method shown in FIG. 2 , after step S1023 is performed, the following steps may be further included: from extracting to , delete the delimiter that does not match the preset format.

In an exemplary embodiment, the preset format may be "/dev/sd*", where "*" may be a wildcard character identifying any alphanumeric character or the like. In this way, by traversing and comparing step S1023 to obtain each character in the hard disk identification, it can be determined that "/dev/sdb:" does not match the preset format, and a separator ":" is added at the end, and the separator ":" needs to be removed. . Similarly, by calling the "awk" command, the separator can be removed, so as to obtain the hard disk identification that meets the preset format, so that it can be directly called by the subsequent steps to improve the refresh speed of the hard disk firmware.

Step S103: Filter the first list to obtain a second list.

Since the storage system may include multiple hard disks that do not need to be refreshed, firmware refresh through the first list may refresh to unnecessary hard disks, affecting the firmware refresh speed, and may even cause hard disk failure due to forcible firmware refresh.

Referring to FIG. 3 , it is a schematic flowchart of a screening method provided by an embodiment of the present invention. As shown in FIG. 3, an embodiment of the present invention shows a process of filtering the first list:

Step S1031: Obtain the firmware version number of the hard disk according to the hard disk identifier.

The firmware version number of the hard disk corresponding to the hard disk identifier can be acquired by invoking a corresponding query command according to the hard disk identifier.

Step S1032: when the firmware version number is equal to the preset reference version number, delete the corresponding hard disk identifier from the first list to obtain a second list.

The corresponding relationship between the hard disk identifier and the reference version number can be established for the hard disk used in the storage system in advance. For example, the first hard disk identifier corresponds to the first reference version number, the second hard disk identifier corresponds to the second reference version number, the first reference version number is the firmware version to which the first hard disk can be refreshed, and the second reference version number is the second hard disk. The firmware version that can be flashed to.

When the firmware version number is equal to the preset reference version number, for example, the firmware version number of the first hard disk obtained by the query in step S1031 is equal to the first reference version number, then the hard disk identifier corresponding to the first hard disk is removed from the first list. deleted in . By traversing all the hard disks corresponding to the first list, after judging the firmware version numbers and the corresponding reference version numbers of all the hard disks and performing the above operations, a filtered second list can be obtained. The second list includes hard disks whose firmware needs to be refreshed, so as to prevent re-flashing, improve the accuracy of hard disk firmware refreshing, and further improve the refresh quality.

Step S104: Refresh the corresponding firmware file to each hard disk in the second list.

In the first implementation situation, all hard disks used by the storage system may be hard disks of the same manufacturer, same type, and same model, to ensure the compatibility of the storage system. For example, the hard disks are all SATA-type mechanical hard disks produced by manufacturer A and have the same model, so that all hard disks in the storage system can be upgraded using the same firmware file.

In the second implementation situation, the storage system may use hard disks produced by different manufacturers, the same type of hard disks produced by different manufacturers, or different types of hard disks produced by the same manufacturer, or different types of hard disks produced by manufacturers. In the storage system, there may be multiple hard disks, and each hard disk needs to be refreshed with different firmware files. Referring to FIG. 4 , it is a schematic flowchart of a method for refreshing a hard disk according to an embodiment of the present invention. As shown in Figure 4, the method includes:

Step S1041: Select a firmware file corresponding to the hard disk from the firmware library according to the hard disk identifier in the second list.

During specific implementation, a firmware library including a variety of different firmware files can be established, and the firmware files in the firmware library correspond to hard disks of corresponding manufacturers, types and models. Moreover, a corresponding relationship between the hard disk identifier and the firmware file is established, and the firmware file corresponding to the hard disk identifier can be determined by querying the corresponding relationship. In an exemplary embodiment, the firmware library may include a first firmware file and a second firmware file, the first firmware file has a corresponding relationship with the first hard disk identifier, and the second firmware file has a corresponding relationship with the second hard disk identifier. When the first hard disk needs to be refreshed, it can be determined that the first firmware file needs to be refreshed by using the first hard disk identifier.

Step S1042: Refresh the selected firmware file to the corresponding hard disk.

According to the selected firmware file, refresh the corresponding firmware file to the corresponding hard disk. In an exemplary embodiment, the first firmware file is selected through step S1041, and the first firmware file is used when the firmware of the first hard disk is refreshed.

Also, in an exemplary embodiment, a corresponding flash tool can be used to flash the firmware using a flash command. For example, using the "seaflashlin" tool, you can complete the corresponding firmware update by specifying the name of the firmware file and the hard disk identification. Of course, it should be noted that any other firmware refresh tool may be used in this embodiment of the present invention, which is not limited in this embodiment of the present invention.

In addition, in the process of firmware refresh, it can be done in a serial manner by calling the refresh command cyclically. Alternatively, a parallel manner can be used to simultaneously call multiple refresh commands to perform firmware refresh in a concurrent process, thereby improving firmware refresh efficiency.

As can be seen from the description of the above-mentioned embodiments, a method for refreshing hard disk firmware provided in the embodiment of the present invention obtains the hard disk information of all the hard disks in the storage system; extracts the hard disk identifiers from the hard disk information to form a first list; The first list is filtered to obtain a second list; the corresponding firmware file is refreshed to each hard disk in the second list. In this embodiment of the present invention, hard disk identifiers are extracted from hard disk information, a first list is formed by rough screening, and a second list is obtained by precise screening. The second list can include all hard disks whose firmware needs to be refreshed. According to the second list, the firmware Refresh, thereby ensuring that all required hard drives are firmware refreshed, improving firmware refresh quality.

Referring to FIG. 5 , it is another method for refreshing hard disk firmware provided by an embodiment of the present invention. As shown in FIG. 5 , on the basis of the method for refreshing the hard disk firmware shown in FIG. 1 , the embodiment of the present invention may further verify the firmware refreshing result after the firmware refreshing is completed, so as to ensure the quality of the firmware refreshing. The refresh method includes:

Step S201: Acquire hard disk information of all hard disks in the storage system.

Step S202: Extract the hard disk identifier from the hard disk information to form a first list.

Step S203: Filter the first list to obtain a second list.

Step S204: Refresh the corresponding firmware file to each hard disk in the second list.

Step S205: Obtain the firmware version number of the hard disk after the firmware is refreshed.

In an exemplary embodiment, after the first hard disk completes the firmware refresh, the firmware version number of the first hard disk is obtained.

Step S206 : when the firmware version number is not equal to the preset reference version number, an error message is sent, and the error message carries a corresponding hard disk identifier to indicate that the corresponding hard disk firmware is refreshed incorrectly.

Through the correspondence between the first hard disk identifier and the reference version number, the reference version number to which the first hard disk needs to be refreshed can be determined. When the firmware version number of the first hard disk is not equal to the reference version number, it means that the firmware of the first hard disk is refreshed incorrectly. Further, an error message can be sent, and the error message carries the corresponding hard disk identification, and the technician can be notified in time to check the corresponding hard disk through the error message.

Moreover, after the error message is sent, it is also possible to continue to return to step S204 to refresh the firmware until the hard disk firmware is refreshed successfully.

For the similarities between the embodiments of the present invention and the foregoing embodiments, reference may be made to the descriptions of the foregoing embodiments, and details are not described herein again.

It can be seen from the description of the above embodiment that another method for refreshing hard disk firmware provided by the embodiment of the present invention, after the firmware is refreshed, the hard disk to be refreshed is verified, and if the verification of the hard disk fails, an error message is sent to show Timely processing can improve the success rate of hard disk firmware refresh and further improve the quality of hard disk refresh.
