Description

Technical Field

[0001] The present disclosure relates to the field of computer technologies, and in particular, to a method, apparatus, device, and storage medium for obtaining a BMC IP. Background Art

[0002] A baseboard management controller (BMC) is used to manage a server. Through the BMC, system logs of the server can be viewed, etc. To access the BMC, the Internet Protocol (IP) address of the BMC needs to be obtained. However, in some abnormal situations, such as when there is no available display or the server malfunctions, even if a display is connected, it is impossible to enter the operating system and the Basic Input Output System (BIOS) to obtain the BMC IP of the server.

[0003] In view of the problem of difficultly obtaining the BMC IP in the above abnormal situations, the prior art mainly has the following two solutions:

[0004] (1) Using a BMC serial cable to obtain the BMC IP, that is, connecting the BMC serial cable to the BMC serial port, directly entering the BMC's own system through the user name and password, and directly reading the BMC IP using the ifconfig command. However, this method requires preparing a BMC serial cable;

[0005] (2) Obtaining the BMC IP according to the Media Access Control (MAC) address, that is, viewing the MAC address on the BMC motherboard, entering the Dynamic Host Configuration Protocol (DHCP) server, viewing the IP assigned to the corresponding MAC address, or analyzing the correspondence between the MAC address and the IP within the network segment through software, so as to obtain the BMC IP. However, this method requires opening the chassis to view the MAC address on the motherboard, and the MAC address on the motherboard may be inconsistent with the actual MAC address of the BMC.

[0028] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0029] Figure 1 A flowchart showing a method for obtaining a BMC IP in the first embodiment of the present disclosure is shown, as Figure 1 shown, the method mainly includes:

[0030] Step S101, when the baseboard management controller BMC is connected to the current network segment, perform a connectivity test on the Internet protocol IP addresses in the current network segment to obtain a first test result, and determine the IP addresses indicating successful connectivity in the first test result as the first address pool.

[0031] In this embodiment, first, it is necessary to test the connectivity of Internet Protocol (IP) addresses within the current network segment when the Baseboard Management Controller (BMC) can work properly and is connected to the current network segment, obtain a first test result, and determine the IP addresses indicating successful connectivity in the first test result as the first address pool. Among them, if the BMC is connected to a network cable, it is considered that the BMC is connected to the current network segment. Specifically, the target IP address of the BMC is included in multiple IP addresses within the current network segment. And because the BMC is connected to the current network segment, the target IP address can be connected during the connectivity test. By determining the IP addresses indicating successful connectivity among multiple first test results as the first address pool, the target IP address of the BMC will surely be included in the first address pool.

[0032] In an implementable manner, the connectivity of IP addresses within the current network segment can be tested through the nbtsacn command or the ping command. When the nbtsacn command is used for the connectivity test, it will send NetBIOS (Network Basic Input / Output System) status queries to each IP address within the current network segment. For each IP address that responds to the NetBIOS status query, the nbtsacn command will list its corresponding IP address, NetBIOS computer name, logged-in user name, MAC address, etc.; when the ping command is used for the connectivity test, it will send test data packets to each IP address within the current network segment, receive the response data of the IP address for the test data packets, and count the response time to test whether the IP address is connected.

[0033] Step S102: When the BMC is disconnected from the current network segment, test the connectivity of IP addresses within the current network segment, obtain a second test result, and determine the IP addresses indicating successful connectivity in the second test result as the second address pool.

[0034] In this embodiment, it is also necessary to test the connectivity of IP addresses within the current network segment when the BMC is disconnected from the current network segment, obtain a second test result, and determine the IP addresses indicating successful connectivity in the second test result as the second address pool. Among them, if the BMC is disconnected from the network cable, it is considered that the BMC is disconnected from the current network segment. Specifically, although the target IP address of the BMC is included in multiple IP addresses within the current network segment, because the BMC is disconnected from the current network segment, the target IP address cannot be connected during the connectivity test. By determining the IP addresses indicating successful connectivity among multiple second test results as the second address pool, the target IP address of the BMC will surely not be included in the second address pool. Preferably, in step S102, the connectivity of IP addresses within the current network segment can also be tested through the nbtsacn command or the ping command.

[0035] Step S103: Compare the first address pool and the second address pool to obtain a target address pool, where the target address pool includes the different IP addresses in the first address pool and the second address pool.

[0036] Step S104: Determine the target IP address of the BMC according to the target address pool.

[0037] In this embodiment, since the target IP address of the BMC must be included in the first address pool and definitely not included in the second address pool, therefore, by comparing the differences between the first address pool and the second address pool and determining the different IP addresses in the first address pool and the second address pool as the target address pool, the target IP address of the BMC must be included in the target address pool, and the target IP address of the BMC can be determined according to the target address pool.

[0038] In an implementable manner, if there is only one IP address in the target address pool, the IP address can be determined as the target IP address of the BMC; if there are multiple IP addresses in the target address pool, for each IP address in the target address pool, respectively conduct a connectivity test on the IP address when the BMC is connected to the current network segment and when the BMC is disconnected from the current network segment. If the IP address is successfully connected when the BMC is connected to the current network segment and the IP address fails to connect when the BMC is disconnected from the current network segment, then the IP address is determined as the target IP address of the BMC.

[0039] In the first embodiment of the present disclosure, the first address pool obtained when the BMC is connected to the current network segment includes the target IP address of the BMC, and the second address pool obtained when the BMC is disconnected from the current network segment does not include the target IP address of the BMC. The different IP addresses in the first address pool and the second address pool are used as the target address pool, that is, the target address pool includes the target IP address of the BMC. Therefore, finally, the target IP address of the BMC can be determined according to the target address pool. In this way, when obtaining the target IP address of the BMC, there is no need to prepare a BMC serial cable, nor to open the chassis to view the MAC address on the motherboard and log in to the DHCP server.

[0040] In the second embodiment of the present disclosure, step S103 mainly includes:

[0041] Generate a first file according to the first IP address in the first address pool; generate a second file according to the second IP address in the second address pool; compare the differences between the first file and the second file according to the file comparison command to obtain the target address pool.

[0042] In this embodiment, when comparing the differences between the first address pool and the second address pool, first, according to the first IP addresses in the first address pool, a first file containing all the first IP addresses can be generated. Then, according to the second IP addresses in the second address pool, a second file containing all the second IP addresses can be generated. Finally, according to the file comparison command, the first file and the second file are compared for differences, and the target address pool is composed of the different IP addresses in the first address pool and the second address pool.

[0043] In an implementable manner, all the first IP addresses in the first address pool can be written into a file to obtain the first file, and the second IP addresses in the second address pool can be written into a file to obtain the second file.

[0044] In an implementable manner, the file comparison command can be the vimdiff command or the grep command. Among them, the vimdiff command can compare the different parts in the first file and the second file and highlight the different parts; the grep command can compare the string data in the first file and the second file and print out the different strings in the first file and the second file.

[0045] In the second embodiment of the present disclosure, generating a first file from the first IP addresses in the first address pool, generating a second file from the second IP addresses in the second address pool, and comparing the first file and the second file for differences according to the file comparison command to obtain the target address pool can improve the efficiency of comparing the differences between the first address pool and the second address pool.

[0046] In the third embodiment of the present disclosure, step S103 further includes:

[0047] Comparing the differences between the first address pool and the second address pool to obtain an initial address pool; judging whether the number of IP addresses in the initial address pool meets a preset threshold to obtain a judgment result; if the judgment result is yes, determining the initial address pool as the target address pool; if the judgment result is no, reconnecting the BMC to the current network segment and performing a connectivity test on the IP addresses in the current network segment to obtain a third test result, determining the IP addresses indicating successful connectivity in the third test result as the third address pool, and comparing the differences between the first address pool and the third address pool until the judgment result is yes.

[0048] In this embodiment, since there is only one target IP address of the BMC, in an ideal state, there should also be only one IP address in the target address pool. However, when performing a connectivity test on the BMC, there will be some interference factors. For example, when the BMC is connected to the current network segment, other devices are also connected to the current network segment, and when the BMC is disconnected from the current network segment, other devices happen to be disconnected from the current network segment as well. In this way, when performing a connectivity test on the IP addresses in the current network segment, other devices will affect the number of IP addresses in the target address pool.

[0049] In this embodiment, in order to ensure that the number of IP addresses in the target address pool meets the preset threshold, first, a difference comparison is performed between the first address pool and the second address pool to obtain an initial address pool, and then it is determined whether the number of IP addresses in the initial address pool meets the preset threshold to obtain a judgment result. If the judgment result is yes, the initial address pool is determined as the target address pool; if the judgment result is no, the IP addresses in the current network segment are re-tested for connectivity with the BMC disconnected from the current network segment to obtain a third test result, and the IP addresses indicating successful connectivity in the third test result are determined as the third address pool. This is equivalent to adjusting the IP addresses in the second address pool to obtain the third address pool, and a difference comparison is performed between the first address pool and the third address pool until the judgment result is yes, and the initial address pool corresponding to when the judgment result is yes is determined as the target address pool. Specifically, the preset threshold can be set according to the actual situation. For example, the preset threshold can be 1 to 3.

[0050] In the third embodiment of the present disclosure, a difference comparison is performed between the first address pool and the second address pool to obtain an initial address pool, and it is determined whether the number of IP addresses in the initial address pool meets the preset threshold to obtain a judgment result. If the judgment result is yes, the initial address pool is determined as the target address pool; if the judgment result is no, the IP addresses in the current network segment are re-tested for connectivity with the BMC disconnected from the current network segment to obtain a third test result, and the IP addresses indicating successful connectivity in the third test result are determined as the third address pool, and a difference comparison is performed between the first address pool and the third address pool until the judgment result is yes. Thus, interference factors can be excluded, and it is ensured that the number of IP addresses in the target address pool meets the preset threshold, facilitating the subsequent determination of the target IP address of the BMC based on the target address pool.

[0051] Figure 2 shows a schematic flow diagram of a method for obtaining a BMC IP in the fourth embodiment of the present disclosure, as Figure 2 shown, step S104 mainly includes:

[0052] Step S201: When the BMC is connected to the current network segment, perform a connectivity test on the test IP address to obtain a fourth test result. Here, the test IP address is an IP address in the target address pool.

[0053] Step S202: If the fourth test result indicates that the test IP address is successfully connected, then when the BMC is disconnected from the current network segment, perform a connectivity test on the test IP address to obtain a fifth test result.

[0054] Step S203: If the fifth test result indicates that the test IP address is not successfully connected, then determine the test IP address as the target IP address.

[0055] Step S204: If the fifth test result indicates that the test IP address is successfully connected, then determine another IP address in the target address pool as the test IP address, and when the BMC is connected to the current network segment, perform a connectivity test on the test IP address until the fifth test result indicates that the test IP address is not successfully connected.

[0056] Step S205: If the fourth test result indicates that the test IP address is not successfully connected, then determine another IP address in the target address pool as the test IP address, and when the BMC is connected to the current network segment, perform a connectivity test on the test IP address until the fourth test result indicates that the test IP address is successfully connected.

[0057] In this embodiment, first, select an IP address from the target address pool as the test IP address. Then, when the BMC is connected to the current network segment, perform a connectivity test on the test IP address to obtain a fourth test result. If the fourth test result indicates that the test IP address is successfully connected, then when the BMC is disconnected from the current network segment, perform a connectivity test on the test IP address to obtain a fifth test result, and determine the target IP address according to the fifth test result; if the fourth test result indicates that the test IP address is not successfully connected, then determine another IP address in the target address pool as the test IP address, and perform a connectivity test on the test IP address again when the BMC is connected to the current network segment until the fourth test result indicates that the test IP address is successfully connected.

[0058] In this embodiment, when determining the target IP address according to the fifth test result, if the fifth test result indicates that the test IP address fails to connect, it proves that the test IP address can be connected when the BMC is connected to the current network segment and cannot be connected when the BMC is disconnected from the current network segment. Then, the test IP address can be determined as the target IP address. If the fifth test result indicates that the test IP address is successfully connected, it proves that the connection status of the test IP address with the BMC network segment is irrelevant and it is not the target IP address. Then, another IP address in the target address pool is determined as the test IP address, and the connectivity test of the test IP address is performed again when the BMC is connected to the current network segment until the fifth test result indicates that the test IP address fails to connect.

[0059] In the fourth embodiment of the present disclosure, for each IP address in the target address pool, if the IP address is successfully connected when the BMC is connected to the current network segment and fails to connect when the BMC is disconnected from the current network segment, then the IP address is determined as the target IP address of the BMC, so that an accurate target IP address can be obtained from the target address pool.

[0060] In the fifth embodiment of the present disclosure, a method for obtaining a BMC IP further includes:

[0061] According to the target IP address, a lighting instruction is sent to the BMC. When the BMC lights up the positioning light in response to the lighting instruction, the target IP address is determined as the correct IP address of the BMC.

[0062] In this embodiment, after obtaining the target IP address of the BMC, a lighting instruction can be sent to the target IP address. If the BMC lights up its own positioning light in response to the lighting instruction, it can be determined that the target IP address is the correct IP address of the BMC. Thus, the target IP address of the BMC can be further verified to ensure that the correct IP address is obtained.
