Abstract

This invention proposes a testing method, system, device, and storage medium based on multi-path aliases. The method includes: storing two mapped devices to a server; recording the initial assigned aliases for the two mapped devices; setting aliases for the two mapped devices and checking if the alias settings are correct; if the alias settings are correct, deleting one of the mapped devices and setting the alias of the other available mapped device as the initial assigned alias of the deleted mapped device; checking if the setting was successful; if successful, remapping the deleted mapped device to the server and ending the test; if it fails, the test fails and a failure message is returned. This invention can effectively verify the stability of the multi-path alias function, ensuring that the automatic assignment of aliases for deleted devices has no impact on the use of alias functions by normally mapped devices, thereby improving the reliability of multi-path products.

Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to a testing method, system, apparatus, and storage medium based on multi-path aliases. Background Technology

[0002] From the operating system's perspective, each path is perceived as a physical disk, but in reality, they are simply different paths leading to the same physical disk. This can be confusing for users. Multipathing software was developed to address this issue. Multipathing technology allows the use of more than one physical path to access network storage devices. Its main function is to work with storage devices to achieve the following: failover and recovery, I / O load balancing, disk virtualization, and even finer-grained I / O scheduling strategies, providing higher availability and performance advantages for network storage systems. It has been widely adopted in storage network environments.

[0003] When configuring multipathing, block devices are automatically assigned a default name on the host side. Users can also change the alias of the block device using the block device's WWID (each SCSI disk has a unique WWID, similar to a network card's MAC address). To ensure the stability and reliability of automatically assigned aliases and user-defined aliases, many testing methods exist, but none test the difference between automatically assigned aliases for deleted devices and user-defined aliases for normally used devices.

[0004] Existing technologies only provide testing methods for alias setting rules and error mechanisms. For example, storage maps two devices to a server, checks their initial assigned names, and sets the alias of one device as the initial assigned alias of the other device to trigger the abnormal operation mechanism of multipath alias setting. When the alias of a device is set to a name outside the multipath alias setting rules, naming rule issues can be triggered. However, existing testing methods only test normally mapped devices, ignoring the impact of automatically assigned aliases of deleted devices on the alias setting function of devices still in normal use. Summary of the Invention

[0005] To address the above problems, the present invention aims to provide a testing method, system, device, and storage medium based on multi-path aliases.

[0006] To achieve the above objectives, this invention provides the following technical solution: a testing method based on multi-path aliases, comprising: The storage is mapped to the server from two devices; Record the initial aliases assigned to the two mapping devices; Set aliases for the two mapping devices and check if the alias settings are correct; If the alias is set correctly, delete one of the mapped devices and set the alias of the other available mapped device to the initial assigned alias of the deleted mapped device; Check if the settings were successful; If successful, the deleted mapped device will be remapped to the server, and the test will end. If it fails, the test fails and a failure message is returned.

[0007] Furthermore, the storage mapping between the two devices and the server includes: The storage maps two devices to the server, and uses multipath detection to view device information.

[0008] Furthermore, the step of setting aliases for the two mapping devices and checking whether the alias settings are correct also includes: If the alias is not set correctly, the test will fail and return a failure message.

[0009] Furthermore, the step of remapping the deleted mapping device to the server and ending the test includes: Check if there are any issues with the device information. If the device information is normal, remap the deleted device to the server and use multipath detection to check if there are any issues with the information of the two mapped devices. If there are no issues, end the test.

[0010] Accordingly, the present invention also discloses a testing system based on multi-path aliases, comprising: The mapping unit is used to store the mapping between two devices and the server; The recording unit is used to record the initial aliases assigned to the two mapping devices; The configuration unit is used to set aliases for the two mapped devices and check whether the alias settings are correct. The deletion unit deletes one of the mapping devices and sets the alias of the other available mapping device to the initial assigned alias of the deleted mapping device. The judgment unit is used to determine whether the alias setting was successful. The secondary mapping unit is used to remap deleted mapping devices to the server.

[0011] Furthermore, the mapping unit is specifically used for: The storage maps two devices to the server, and uses multipath detection to view device information.

[0012] Furthermore, the setting unit is specifically used for: Set aliases for the two mapped devices and check if the alias settings are correct; if the alias settings are incorrect, the test will fail and a failure message will be returned.

[0013] Furthermore, the secondary mapping unit is specifically used for: Check if there are any issues with the device information. If the device information is normal, remap the deleted device to the server and use multipath detection to check if there are any issues with the information of the two mapped devices. If there are no issues, end the test.

[0014] Accordingly, this invention discloses a testing device based on multi-path aliases, comprising: Memory used to store test programs based on multi-path aliases; A processor, configured to implement the steps of the test method based on multi-path aliases as described above when executing the test program based on multi-path aliases.

[0015] Accordingly, the present invention discloses a readable storage medium storing a test program based on multi-path aliases, wherein when the test program based on multi-path aliases is executed by a processor, it implements the steps of the test method based on multi-path aliases as described in any of the above.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This invention provides a testing method, system, device, and storage medium based on multi-path aliases, filling the gap in testing the impact of deleted device information on the setting of aliases for normally used mapped devices. Using the testing method of this invention, the stability of the multi-path alias function can be effectively verified, ensuring that the automatic allocation of aliases for deleted devices has no impact on the normal use of aliases for mapped devices, thereby improving the reliability of multi-path products.

[0017] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0019] Appendix Figure 1 This is a flowchart illustrating a specific embodiment of the present invention.

[0020] Appendix Figure 2 This is a system structure diagram of a specific embodiment of the present invention. Detailed Implementation

[0021] The core of this invention is to provide a testing method based on multi-path aliases. Existing technologies only provide testing methods for alias setting rules and error mechanisms. For example, storage maps two devices to a server, checks their initial assigned names, and sets the alias of one device as the initial assigned alias of the other device to trigger the abnormal operation mechanism of multi-path alias setting. When the alias of a device is set outside the multi-path alias setting rules, a naming rule problem can be triggered. However, existing testing methods only test normally mapped devices, ignoring the impact of automatically assigned aliases of deleted devices on the alias setting function of devices still in normal use.

[0022] The multi-path alias-based testing method provided by this invention first stores the mappings of two devices to a server and records the initial aliases assigned to the two mapped devices. Then, it sets the aliases for the two mapped devices and checks if the alias settings are correct. If the alias settings are correct, it deletes one of the mapped devices and sets the alias of the other available mapped device to the initial assigned alias of the deleted mapped device. At this point, it checks if the setting was successful. If successful, it remaps the deleted mapped device to the server and ends the test; if it fails, the test fails and a failure message is returned. Therefore, this invention can effectively verify the stability of the multi-path alias function, ensuring that the automatic assignment of aliases to deleted devices does not affect the use of the alias function by normally mapped devices, thereby improving the reliability of multi-path products.

[0023] 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.

[0025] S2: Records the initial aliases assigned to the two mapping devices.

[0026] S3: Set aliases for the two mapped devices and view the alias settings.

[0027] S4: Determine if the alias setting is normal; if normal, proceed to the next step; if not normal, the test fails and a failure message is returned.

[0028] S5: Delete one of the mapping devices and set the alias of the other available mapping device to the initial assigned alias of the deleted mapping device.

[0029] S6: Check if the setup was successful; if successful, proceed to the next step; if unsuccessful, the test failed and a failure message is returned.

[0030] S7: Check if there are any problems with the device information; if there are any abnormalities, the test will fail and a failure message will be returned; if there are no abnormalities in the device information, proceed to the next step.

[0031] S8: Remap the deleted mapping device to the server, and use multipath detection to view the information of the two mapping devices; S9: Determine if there is an abnormality in the device; if there is an abnormality, the test fails and a failure message is returned; if there is no abnormality, the test ends.
