[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] The existing adaptation method of a storage management software and a storage system is usually started from a product name, and each version product is under a known topology. The corresponding adaptation logic is provided according to the known topology, which makes it necessary to re-adapt even if the hardware topology structure does not change when a new product version is added. The hardware adaptation and product name are bound, which is not easy to expand and maintain. Therefore, the present application provides an adaptation scheme of a storage management software and a storage system, which can avoid unnecessary adaptation process of the storage management software and the storage system, and is easy to expand and maintain.

[0052] Referring to Figure 1 The embodiments of the present application disclose an adaptation method of a storage management software and a storage system, which comprises:

[0053] Step S11: identifying the hardware topology structure of the storage system.

[0054] In a specific embodiment, the type and number of disk array cards accessing the storage system, the number of expander cards, and the connection relationship between the expander cards and the disk array cards can be identified to obtain the hardware topology of the storage system.

[0055] Further, the type and number of disk array cards connected to the PCI bus of the storage system can be obtained by invoking the lspci hardware command. The number of expander cards accessing the storage system and the connection relationship between the disk array cards and the expander cards can be obtained by invoking the lsscsi command to obtain the hardware topology of the storage system. The disk array cards include but are not limited to RAID (Redundant Arrays of Independent Disks) cards, SAS (Serial Attached SCSI) cards, and PMC (Sierra) cards, and can be extended based on the type of newly added disk array cards. The SAS card can be a SAS2008 and SAS3008 disk array card. The RAID card can be a SAS3408 and SAS3508 disk array card. The lsscsi command is a command for querying device information and can list SCSI (Small Computer System Interface) devices (or hosts) and their attributes. Lspci is a tool for displaying all PCI (Peripheral Component Interconnect) bus devices or all devices connected to the bus in the system.

[0056] Step S12: invoking the adaptation logic corresponding to the hardware topology, and determining the disk logical slot number and the correspondence between the disk drive letter in the storage system and the disk logical slot number by using the adaptation logic, to complete the adaptation of the storage management software and the storage system under the hardware topology.

[0057] In a specific embodiment, the adaptation logic name can be constructed based on the type and number of disk array cards and the number of expander cards, and the adaptation logic corresponding to the hardware topology can be invoked based on the adaptation logic name. The adaptation logic is an adaptation processing class, and accordingly, invoking the adaptation logic corresponding to the hardware topology includes constructing an adaptation processing class name based on the type and number of disk array cards and the number of expander cards, and invoking the adaptation processing class corresponding to the hardware topology based on the adaptation processing class name. For example, when there is one PMC card connected to three expanders, the final processing class name is pmc_one_expander_three.

[0058] It can be understood that the present application can create corresponding adaptation logic based on different hardware topologies, and when any hardware topology is identified, the corresponding adaptation logic is called for adaptation.

[0059] Further, the embodiments of the present application can use the adaptation logic to perform the following steps:

[0060] Step 00: Determine the disk logical slot number and the first correspondence between the disk serial number and the disk logical slot number in the storage system.

[0061] In an embodiment, the real slot number of each of the expansion cards in the storage system can be obtained through a hardware management command; the disk logical slot number is determined based on the hardware topology and the real slot number, and the first correspondence between the disk serial number and the disk logical slot number is determined.

[0062] The determination of the disk logical slot number based on the hardware topology and the real slot number includes: determining the to-be-offset expansion card and the offset amount of the to-be-offset expansion card based on the hardware topology; determining the disk logical slot number of the to-be-offset expansion card based on the offset amount and the real slot number of the to-be-offset expansion card; determining the real slot number of the non-to-be-offset expansion card as the disk logical slot number of the non-to-be-offset expansion card. Furthermore, if any of the disk array cards is connected to multiple expansion cards, the SAS addresses of the multiple expansion cards are obtained, the expansion card connection relationship of the multiple expansion cards is determined based on the SAS addresses, and the hardware topology determines the to-be-offset expansion card and the offset amount of the to-be-offset expansion card based on the expansion card connection relationship.

[0063] It should be noted that, since the slot numbers of the disks connected to each expander obtained by the hardware command are actually the same, that is, the real slot numbers of the disks on each expander are the same, and need to be logically allocated by the adaptation logic, therefore, different hardware topologies need to correspond to different adaptation logics. Taking a storage system with one pmc card and three expanders as an example, each expander is connected with 12 disks. The backplanes of the three expanders correspond to the front upper backplane (logical slot number allocation is 0 to 11), the front lower backplane (logical slot number allocation is 12 to 23), and the rear backplane (logical slot number allocation is 24 to 35) respectively. The rear backplane is connected to the front lower backplane through wiring. The correspondence between the expander disk slot number and the serial number can be obtained by the sg_ses command. The disk slot numbers connected by the three expanders in the correspondence are all 0 to 11. According to different topologies, the obtained slot numbers are further allocated. The sas address of each expander expansion card and the sas address of the expansion card connected thereto are obtained by the sg_inq command. According to the obtained sas address, when the attached sas address of the backplane of a certain expander A is the sas address of the backplane of another expander B, it indicates that the backplane of the expander A is connected to the backplane of the expander B, and it is concluded that the backplane of the expander A is the rear backplane, which needs to be offset by 24 based on the real slot number, that is, from 0 to 11 to 24 to 35, to obtain the logical slot number allocated in the whole system; the backplane of the expander B is the front lower backplane, which needs to be offset by 12 based on the real slot number, that is, from 0 to 11 to 12 to 23, to obtain the logical slot number allocated in the whole system; the remaining one expander corresponds to the front upper backplane and does not need to be offset. Finally, the correspondence between the serial number and the logical slot number of all the disks is obtained. Other topologies are similar, and the correspondence between the serial number and the logical slot number of all the disks is obtained by a certain offset logic. For example, there are multiple disk array cards in the storage system, each disk array card is connected with one expansion card, and each expansion card is connected with 12 disks. The expansion card corresponding to the first disk array card does not need to be offset, the expansion card corresponding to the second disk array card is offset from 0 to 11 to 12 to 23, and the expansion card corresponding to the second disk array card is offset from 0 to 11 to 24 to 35.

[0064] Step 01: Obtain a second correspondence between the disk drive letter and the disk serial number in the storage system.

[0065] Step 02: Based on the first correspondence and the second correspondence, determine the correspondence between the disk drive letter and the logical slot number of the disk.

[0066] In one implementation, the mapping between disk drive letters and disk serial numbers can be obtained using commands such as `lsblk`. This mapping is then combined with the mapping between disk serial numbers and logical disk slot numbers obtained in step 00 to ultimately obtain the mapping between disk drive letters and logical disk slot numbers in the storage system, thus enabling management software adaptation under the corresponding hardware topology. The `lsblk` command is used to list information about all available block devices.

[0067] In other words, in this embodiment, the adaptation logic calls the corresponding hardware management commands based on the hardware topology to obtain the correspondence between the disk serial number and the disk logical slot number; then, by calling the hardware commands related to the disk letter, it obtains the correspondence between the disk letter and the serial number; finally, it associates these two correspondences to obtain the correspondence between the disk letter and the disk logical slot number. When adding a new product type, as long as the topology remains unchanged, no re-adaptation is required. When the topology changes, only the corresponding processing class needs to be added, making it easy to maintain and expand. This overcomes the problem of the original management software adaptation scheme, which, from a product perspective, requires re-adaptation for each new product version, even if the hardware topology is the same, making maintenance cumbersome.

[0068] For example, see Figure 2 As shown, Figure 2 This is a flowchart illustrating a specific method for adapting storage management software to a storage system, as disclosed in an embodiment of this application. The process begins by obtaining the type and quantity of the disk array card (pmc_1 represents one PMC card, with the newly added card type being the type that can be expanded later). Then, the number of expanders is obtained (expander_3 represents three expanders). Next, the processing class is obtained, named pmc_1_expander_3. Further, SAS or PMC cards do not need to list system disk information, while RAID cards do. Finally, the disk and card information are associated, as are the mappings between disk drive letters and disk serial numbers, and between disk serial numbers and disk logical slot numbers. This ultimately yields the mapping between disk drive letters and disk logical slot numbers in the storage system, achieving software adaptation under the corresponding hardware topology.

[0069] It can be seen that the embodiment of the application first identifies the hardware topology of the storage system, then calls the corresponding adaptation logic of the hardware topology, and determines the disk logical slot number and the correspondence between the disk drive letter in the storage system and the disk logical slot number by using the adaptation logic, so as to complete the adaptation of the storage management software and the storage system under the hardware topology. That is, the application identifies the hardware topology of the storage system, calls the corresponding adaptation logic to complete the adaptation of the storage management software and the storage system under the corresponding hardware topology. In this way, when the hardware topology does not change, there is no need to re-adapt, and unnecessary adaptation process of the storage management software and the storage system can be avoided. When a new hardware topology is added, the corresponding adaptation logic can be added, which does not affect the original adaptation logic, and is easy to expand and maintain.

[0073] It can be seen that the embodiment of the application first identifies the hardware topology of the storage system, then calls the corresponding adaptation logic of the hardware topology, and determines the disk logical slot number and the correspondence between the disk drive letter in the storage system and the disk logical slot number by using the adaptation logic, so as to complete the adaptation of the storage management software and the storage system under the hardware topology. That is, the application identifies the hardware topology of the storage system, calls the corresponding adaptation logic to complete the adaptation of the storage management software and the storage system under the corresponding hardware topology. In this way, when the hardware topology does not change, there is no need to re-adapt, and unnecessary adaptation process of the storage management software and the storage system can be avoided. When a new hardware topology is added, the corresponding adaptation logic can be added, which does not affect the original adaptation logic, and is easy to expand and maintain.
