Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a method, system, device, and storage medium for setting Expander card management parameters. Background Technology

[0002] JBOD (Just a Bunch Of Disks) is an important type of storage device in the storage field. A JBOD is a storage device with multiple disk drives mounted on a single baseboard. It is often also called a Span. Unlike RAID arrays, JBODs do not have front-end logic to manage the data distribution across the disks. Instead, each disk is addressed individually as a separate storage resource, either as part of the host software or as an adapter card for the RAID group.

[0003] Although JBOD is not a standard RAID level, it has been widely adopted as a means of expanding server storage resources. Due to the different connection methods between JBOD and the server, the management parameters for the server's expander card will differ. For one server with one JBOD, the server's expander card should be set to Zone 3; for one server with four JBODs, the server's expander card should be set to Zone 4.

[0004] Currently, the common practice is to manually configure the management parameters of the expander card on the server based on the on-site connection between the server and the JBOD. However, this method requires manual determination of the connection between the server and the JBOD, and manual configuration is not possible for batch automation. Summary of the Invention

[0005] To address the above problems, the present invention aims to provide a method, system, device, and storage medium for setting Expander card management parameters, which can automatically set the corresponding Expander card management parameters based on the read expander card and JBOD hard disk backplane information when the server and JBOD are already connected.

[0006] To achieve the above objectives, this invention provides the following technical solution: a method for setting Expander card management parameters, comprising:

[0030] Where S is the number of SAS cards and B is the number of hard disk backplanes. If the equation holds true, then the current number of SAS cards matches the number of JBOD management boards; otherwise, they do not match.

[0031] Further, query the number of management boards on the JBOD and determine the connection mode based on the query results, including: using the command lsscsi-sg|grep enclosu|grep'EXP BD'|wc -l to query the number of management boards on the JBOD;

[0032] If the query result is 4, then the current mode is 1-to-4;

[0033] If the query result is 2, then the current mode is 1 drag 2;

[0034] If the query result is 1, then the current mode is 1-to-1.

[0059] The core of this invention is to provide a method for setting Expander card management parameters. In existing technologies, the common practice is to manually set the management parameters of the Expander cards on the server based on the on-site connection between the server and the JBOD. However, this method requires manual determination of the connection method between the server and the JBOD, and manual setting is essential, making it impossible to achieve batch automation.

[0060] The Expander card management parameter setting method provided by this invention first connects the server and JBOD according to the required method, using a PXE server to enable the server to enter the Linux operating system. Then, it reads the SAS card and expander card information and confirms that the SAS card and expander card match; it also reads the number of management boards and hard drive backplanes of the JBOD and confirms that the JBOD management boards and hard drive backplanes match. At this point, it confirms that the number of SAS cards matches the number of management boards of the JBOD, and queries the number of management boards on the JBOD, determining the connection mode based on the query result. Finally, it sets the expander card management parameters according to the connection mode. Therefore, this invention can automatically set the corresponding expander card management parameters based on the read expander card and JBOD hard drive backplane information when the server and JBOD are already connected, effectively saving labor costs.

[0061] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Example 1:

[0063] like Figure 1 As shown, this embodiment provides a method for setting Expander card management parameters, including the following steps:

[0064] S1: Connect the server to the JBOD as required.

[0065] S2: Use a PXE server to boot the server into the Linux operating system;

[0066] S3: Read the SAS card and expander card information, and confirm that the SAS card and expander card are matched.

[0067] First, the scrtnycli tool is used to read the SAS card and expander card information to obtain the number of SAS cards and expander cards. Then, the first matching rule is used to determine whether the current SAS cards and expander cards match. If they do not match, the process terminates and an error message is displayed.

[0068] In this step, the first matching rule is as follows:

[0069]

[0070] Where E is the number of Expander cards and S is the number of SAS cards. If the equation holds true, then the current SAS card and expander card match; otherwise, they do not match.

[0071] S4: Read the number of JBOD management boards and hard disk backplanes, and confirm that the JBOD management boards and hard disk backplanes match.

[0072] First, the number of management boards and hard disk backplanes of the JBOD is read using the lsscsi command. Then, the second matching rule is used to determine whether the current JBOD's management boards and hard disk backplanes match. If they do not match, the process terminates and an error message is displayed.

[0073] In this step, the second matching rule is as follows:

[0074]

[0075] Where J is the number of management boards in the JBOD and B is the number of hard disk backplanes. If the equation holds true, then the relationship between the management boards and hard disk backplanes of the current JBOD is matched; otherwise, they are not matched.

[0076] S5: Confirm that the number of SAS cards matches the number of JBOD management boards.

[0077] Specifically, the third matching rule is used to determine whether the number of SAS cards matches the number of JBOD management boards. If they do not match, the process is terminated and an error message is displayed.

[0078] In this step, the third matching rule is as follows:

[0079] S-1=B

[0080] Where S is the number of SAS cards and B is the number of hard disk backplanes. If the equation holds true, then the current number of SAS cards matches the number of JBOD management boards; otherwise, they do not match.

[0081] S6: Query the number of management boards on the JBOD and determine the connection mode based on the query results.

[0082] First, use the command `lsscsi-sg|grep enclosu|grep 'EXP BD'|wc -l` to query the number of management boards on the JBOD. If the query result is 4, the current mode is 1-to-4; if the query result is 2, the current mode is 1-to-2; if the query result is 1, the current mode is 1-to-1.

[0083] S7: Configure the management parameters of the Expander card according to the connection mode.

[0084] If the current mode is 1-to-1, first, query the sg number of the JBOD management board, then use the sg_senddiag command to set the corresponding Expander card management parameters to zone3, and restart the JBOD management board.

[0085] If the current configuration is 1-to-4, first, set all management boards and backplanes of the JBOD to archive storage mode, read all backplane information of the JBOD to obtain the SG number, and then use the following command to configure all backplanes.

[0086] sg_senddiag-pr 10,0,0,2,4,0 / dev / sgXXX;

[0087] Finally, query the sg number of the JBOD management board and use the sg_senddiag command to set the corresponding Expander card management parameters to zone4.

[0088] This embodiment provides a method for setting Expander card management parameters, which can automatically set the corresponding Expander card management parameters based on the read expander card and JBOD hard disk backplane information when the server and JBOD are already connected.

[0089] Example 2:

[0090] Based on Example 1, such as Figure 2 As shown, this invention also discloses a method for setting Expander card management parameters, the specific steps of which are as follows:

[0092] 2. After entering the Linux operating system, the script setzone.sh will run automatically.

[0093] 3. Use the scrtnycli tool to read SAS card and expander card information.

[0094] 4. Determine if the current SAS card and Expander card are compatible. The matching rules are as follows:

[0095]

[0096] If there is a mismatch, the process will terminate and an error message will be displayed.

[0097] 5. Read the number of JBOD management boards and hard drive backplanes.

[0098] 6. Determine if the JBOD management board (HDD BD) and hard drive backplane (HDD BP) match. The matching rules are as follows:

[0099]

[0100] If there is a mismatch, the process will terminate and an error message will be displayed.

[0101] 7. Determine if the number of SAS cards read matches the number of management boards on the JBOD. The matching rules are as follows:

[0102] Number of IT cards - 1 = Number of HDDs and BDs

[0103] If there is a mismatch, the process will terminate and an error message will be displayed.

[0104] 8. Query the number of management boards on the JBOD. If there are 4, it's a 1-to-4 mode; if there are 2, it's a 1-to-2 mode; if there is 1, it's a 1-to-1 mode. The command to query the number of management boards on the JBOD is: lsscsi-sg|grep enclosu|grep'EXP BD'|wc -l.

[0105] 9. In 1-to-1 mode, set the management parameters of the Expander card to zone3.

[0106] First, query the SG number of the JBOD management board, which is found to be sg2. Then, use the command `sg_senddiag-pr 12,0,0,2,2,3 / dev / sg2` to set the Expander card's management parameters to zone 3. Finally, use the command `sg_senddiag –p –r 10,0,0,1,6 / dev / sg2` to restart the JBOD management board.

[0107] 10. In 1-to-4 mode, set the management parameters of the Expander card to zone4.

[0108] First, set all JBOD management boards and backplanes to archive storage mode, read all JBOD backplane information to obtain the sg number, and then run the following command to configure all backplanes.

[0109] sg_senddiag-pr 10,0,0,2,4,0 / dev / sgXXX

[0110] Then, query the sg number of the JBOD management board and use the following sg_senddiag command to set the management parameters of the Expander card to zone4.

[0111] sg_senddiag-pr 12,0,0,2,2,4 / dev / sgXXX

[0112] This embodiment provides a method for setting Expander card management parameters. It allows the server to automatically read configuration information and set the necessary management parameters without manual intervention. Furthermore, it eliminates the need for frequent manual modifications for frequently changing connection methods; simply restarting the machine allows it to automatically identify the current connection status and configure the settings.

[0117] The first matching unit 3 is used to read SAS card and expander card information and confirm that the SAS card and expander card are matched. Specifically, the first matching unit 3 is used to: use the scrtnycli tool to read SAS card and expander card information to obtain the number of SAS cards and expander cards; determine whether the current SAS card and expander card are matched according to the first matching rule, and if they are not matched, terminate the operation and report an error message.

Specifically, the third matching unit 5 is used to determine whether the number of SAS cards matches the number of JBOD management boards according to the third matching rule. If they do not match, the operation is terminated and an error message is displayed.

[0120] Query unit 6 is used to query the number of management boards on the JBOD and determine the connection mode based on the query result. Specifically, query unit 6 uses the command `lsscsi-sg|grep enclosu|grep 'EXP BD'|wc -l` to query the number of management boards on the JBOD. If the query result is 4, the current mode is 1-to-4; if the query result is 2, the current mode is 1-to-2; and if the query result is 1, the current mode is 1-to-1.
