[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0020] Please refer to Figure 1, which illustrates a storage system design for a computer system. The CPU and RAID card / HBA card are connected via PCIe (Peripheral Component Interconnect Express). The RAID card / HBA card is connected to its backplane via a cable (e.g., SAS (Serial Attached SCSI) cable). The hard drive is inserted into a slot on the backplane. In different computer systems, the model and number of PCIe RAID card / HBA cards may vary; the hard drive backplane design may differ; and the wiring between the RAID card / HBA card and the hard drive backplane may differ.

[0021] Based on the above computer system architecture, various embodiments of this application are proposed.

[0022] Example 1:

[0023] This embodiment provides a storage disk detection method. Please refer to Figure 2. The method includes:

[0024] S201. Control the current state of the target storage disk corresponding to the preset position parameter in each storage disk to be different from the current state of other storage disks;

[0025] S202, Read the current status of each storage disk;

[0026] S203. Based on the current state of each storage disk, determine the mapping relationship between the preset location parameters of the target storage disk and the target location parameters; wherein, the target location parameters include physical location or logical index.

[0027] In this embodiment, the storage disk refers to a memory used to store data. The storage disk is the primary storage medium in a computer, capable of storing large amounts of binary data and retaining it even after power loss. Early computers used floppy disks, while today commonly use hard disks and SSDs (Solid State Disk or Solid State Drive). In the embodiments of this application, the storage disk can be a floppy disk, a hard disk, or an SSD.

[0028] In step S201, controlling the current state of the target storage disk corresponding to the preset location parameters, so that it is different from the current state of other storage disks, means that the preset location parameters are known, and the current state of each storage disk is controlled according to the preset location parameters. The type of preset location parameters can include the logical index of the storage disk or the physical location of the storage disk. The current state is used to identify the differences between storage disks, and these differences are substantial physical differences. Controlling the current state of the target storage disk to be different from the current state of other storage disks is a control method that distinguishes the current state of a specified storage disk from the current state of other storage disks, thereby enabling subsequent identification of that storage disk.

[0029] In some embodiments, before controlling the current state of the target storage disk corresponding to the preset position parameter in each storage disk to be different from the current state of other storage disks, the process may further include:

[0030] Read the list of all in-place storage disks and record the logical index list of all storage disks. An in-place storage disk indicates that it is in the normal power-on and operating process. After recording the logical index list of all in-place storage disks, subsequent control status operations can be performed based on the storage disk's logical index list, and the mapping relationship between the corresponding preset position parameters and target position parameters can be determined based on the storage disk's status.

[0031] In step S202, the current state of each storage disk is read. The current state of each storage disk is the different current state obtained by controlling the storage disks in step S201. This current state is differentiated based on the storage disk; for a given storage disk, its state differs from other storage disks, while the states of other storage disks can be the same.

[0032] In step S203, based on the current state of each storage disk, the mapping relationship between the preset location parameters and the target location parameters of the target storage disk is determined; wherein, the target location parameters include physical location or logical index. Since the current state of the target storage disk can be set according to the logical index or physical location in step S201, which is different from the current state of other storage disks, the logical index or physical location of the target storage disk is determined; and the target location parameters, similar to the preset location parameters, can also include physical location or logical index; in other words, the storage disk detection method in this embodiment is equivalent to knowing one of the logical index and physical location, determining the other corresponding to the storage disk, thereby determining the mapping relationship between the logical index and physical location of the storage disk. The unknown physical location or logical index of the target storage disk can be determined according to the state of each storage disk obtained in step S202, so the mapping relationship from logical index to physical location of the storage disk can be established. For the storage disks in this computer system, by traversing the above operations for each storage disk, the mapping relationship from logical index to physical location of all storage disks can be established, which is equivalent to completing the detection of the storage disk locations in the computer system.

[0033] In some embodiments, controlling the current state of the target storage disk corresponding to a preset location parameter in each storage disk, which differs from the current state of other storage disks, may include:

[0034] The current state of the storage disks is controlled by the RAID storage disk array card / HBA host bus adapter card. RAID is a technology that combines multiple independent hard drives (physical hard drives) in different ways to form a hard drive group (logical hard drive), thereby providing higher storage performance and data redundancy than a single hard drive. A RAID card is a board used to implement RAID functionality, and it is typically composed of a series of components such as an I / O (Input / Output) processor, a SCSI (Small Computer System Interface) controller, a SCSI connector, and cache.

[0035] HBA (Host Bus Adapter) is the physical connection between the server's internal I / O channels and the storage system's I / O channels. An HBA is a circuit board and / or integrated circuit adapter that provides input / output (I / O) processing and physical connectivity between the server and storage devices. Because HBAs reduce the burden on the main processor for data storage and retrieval tasks, they can improve server performance. An HBA and its associated storage disk system are sometimes referred to together as a storage disk channel. The host bus adapter card contains a small central processing unit (CPU), some memory as a data cache, and connectors for Fibre Channel and the bus. This small CPU is responsible for converting between PCI (Peripheral Component Interconnect) and Fibre Channel protocols. It also has other functions, such as initializing server ports connected to the Fibre Channel network, supporting upper-layer protocols such as TCP / IP (Transmission Control Protocol / Internet Protocol), SCSI, and 8B / 10B encoding / decoding. Controlling storage disks through the RAID card / HBA card is a fundamental function of the RAID card / HBA card.

[0036] In some embodiments, the current state of the target storage disk corresponding to the preset position parameter in each storage disk is controlled. Unlike the current state of other storage disks, the current state of the storage disk includes at least one of the following: the indicator light status of the storage disk and the power status of the storage disk. The indicator light status refers to controlling the on / off state of the indicator lights on each storage disk, while the power status refers to whether the power to each storage disk is on or off.

[0037] In some embodiments, when the current state of a storage disk includes the status of an indicator light, the corresponding preset position parameter includes a logical index; and controlling the current state of the target storage disk corresponding to the preset position parameter, which differs from the current state of other storage disks, may include:

[0038] Control the on / off state of the indicator light of the target storage disk corresponding to the control logic index, so that the on / off state of the indicator light of the target storage disk is different from the on / off state of other storage disks;

[0039] The target location parameters include physical location; based on the current state of each storage disk, the mapping relationship between the preset location parameters of the target storage disk and the target location parameters is determined, including:

[0040] Based on the on / off state of the indicator lights, the physical location of the target storage disk is determined, and the mapping relationship between the physical location and the logical index is established. The on / off state of the indicator lights on each storage disk indicates whether the indicator light is lit or off; these two states (on / off) allow for differentiation of the indicator light status of each storage disk. In some cases, controlling the current state of the target storage disk corresponding to a preset location parameter to be different from the current state of other storage disks may include:

[0041] The indicator light on the target storage drive is on, while the indicator lights on other storage drives are off; or,

[0042] The indicator light on the target storage disk is off, while the indicator lights on other storage disks are on. In other words, either only the indicator light on the target storage disk is on, or only the indicator light on the target storage disk is off. Regardless of the state, the target storage disk can be distinguished from other storage disks, and its physical location can be determined. Since the storage disks are controlled by logical indices, meaning the logical index of the target storage disk is known, the mapping relationship between the logical index and physical location of each storage disk can be established one by one.

[0043] In some embodiments, when the current state of the storage disk includes the power state, the corresponding preset location parameter includes the physical location; and controlling the current state of the target storage disk corresponding to the preset location parameter, which differs from the current state of other storage disks, may include:

[0044] Power off the storage disk corresponding to one of the physical locations, while keeping the other storage disks powered on. Accordingly, in some embodiments, the target location parameter includes a logical index; and determining the mapping relationship between the preset location parameter of the target storage disk and the target location parameter based on the current state of each storage disk may include:

[0045] Based on the first index list and the second index list, determine the logical index of the storage disk whose power is turned off;

[0046] The second index list is obtained by reading all currently in-place storage disks and recording the records.

[0047] The first index list is obtained by reading all in-situ storage disks and recording their current states before controlling the current states of the target storage disk corresponding to the preset position parameters. When detecting storage disks by power-on / off, the first index list is obtained by traversing and reading all in-situ storage disks before controlling the state of the storage disks. Then, after powering down the target storage disk with the specified logical index, the in-situ storage disks are read again, and the current second index list is recorded. This second index list is different from the first index list in that the logical index of the powered-down storage disk does not exist in the current index list. This allows us to simultaneously determine the logical index of the powered-down storage disk and, based on the power-down state, the physical location of the powered-down storage disk, which is known. This allows us to establish a mapping relationship between logical indexes and physical locations.

[0048] This embodiment provides a storage disk detection method. It controls the current state of a target storage disk corresponding to a preset location parameter, ensuring this state is different from the current state of other storage disks. The method reads the current state of each storage disk and, based on the current state of each disk, determines the mapping relationship between the preset location parameter and the target location parameter of the target storage disk. The target location parameter includes either a physical location or a logical index. By directly identifying the current storage disk state, the physical location and logical index of the storage disk corresponding to the logical index are determined. This enables real-time adjustment and change of the mapping relationship between the physical location and logical index of the storage disk, improving the accuracy of identification and enhancing the flexibility of computer storage system configuration.

[0049] Example 2

[0050] As shown in Figure 3, this embodiment provides a storage disk detection method, which includes:

[0051] S301. Read the list of all in-place storage disks through the RAID card / HBA card and record their logical index list. The logical index list can be [A, B, C, D], where A, B, C, and D represent logical indices. Please refer to Figure 4. Hard disk indicator light detection logic can be designed on the hardware backplane. This detection logic can be an FPGA (Field Programmable Gate Array), MCU (Microcontroller Unit), etc. In this way, the indicator light of each hard disk can be read from the hard disk indicator light detection logic. The computer system CPU or BMC (Baseboard Management Controller) can access the hard disk indicator light detection logic to read the status of each hard disk indicator light and the physical location information of the hard disk.

[0052] S302. Control the RAID card / HBA card according to the logical index list of the storage disks, turn on the indicator light of the storage disk corresponding to logical index X, and turn off the indicator lights of all other storage disks.

[0053] The S303 and RAID / HBA cards send the LED lighting command to the FPGA or MCU. The FPGA or MCU controls the indicator light (usually an LED) and saves the LED status to the LED status query logic.

[0054] S304. Read the status of the storage disk indicator lights through the LED status query logic of the FPGA or MCU, and identify the index i of the LED status query logic of the lit indicator light.

[0055] S305. Read the physical location of the storage disk in the FPGA or MCU according to index i;

[0056] Repeat the above steps to establish a mapping from the logical index [A, B, C, D] in the RAID card / HBA card to the physical location [a, b, c, d] of all storage disks, thus completing the identification of the physical location of all storage disks.

[0057] Example 3

[0058] As shown in Figure 5, this embodiment provides a storage disk detection method, which includes:

[0059] S501: Read all in-place storage disk information through the RAID card / HBA card and record their logical index list, such as [A, B, C, D]; Please refer to Figure 6. A storage disk power control unit can be designed on the storage disk backplane. The computer management software can control the storage disk power switch on the storage disk backplane through the storage disk power control unit.

[0060] S502, Send a command to the power control unit to turn off the power to storage disk x;

[0061] S503, The power control unit turns off the power to storage disk x;

[0062] S504, The signal link between the storage disk x and the RAID card / HBA is lost, and the RAID card / HBA updates the internal storage disk information in place;

[0063] S505: Read all the storage disks in place again through the RAID card / HBA card and record their current index list, such as [B, C, D];

[0064] S506. Analyze the changes in the logical index in the index list in steps S601 and S605, and find that the logical index of the power-off storage disk is A. Establish the mapping between A and the physical location x of the storage disk in S604.

[0065] Repeat the S501-S506 loop until all storage disks have been identified. Establish a mapping from the logical index [A, B, C, D] in the RAID card / HBA card to the physical location [a, b, c, d] of all storage disks, and complete the identification of the physical location of all storage disks.

[0066] Example 4

[0067] This embodiment provides a storage disk detection device. Please refer to Figure 7. The storage disk detection device includes:

[0068] The status control module 71 is used to control the current status of the target storage disk corresponding to the preset position parameters in each storage disk, which is different from the current status of other storage disks.

[0069] Status reading module 72 is used to read the current status of each storage disk;

[0070] The parameter identification module 73 is used to determine the mapping relationship between the preset location parameters of the target storage disk and the target location parameters based on the current status of each storage disk; wherein, the target location parameters include physical location or logical index.

[0071] In this embodiment, the storage disk refers to a memory used to store data. A storage disk is the primary storage medium in a computer, capable of storing large amounts of binary data and retaining it even after power loss. Early computers used floppy disks as storage disks, while today hard disks and SSDs are commonly used. In the embodiments of this application, the storage disk can be a floppy disk, a hard disk, or an SSD.

[0072] Controlling the current state of a target storage disk corresponding to preset location parameters, differentiating it from the current state of other storage disks, means that the preset location parameters are known, and the current state of each storage disk is controlled based on these parameters. The type of preset location parameters can include the logical index of the storage disk or its physical location. The current state is used to identify the differences between storage disks; these differences are substantial physical differences. Controlling the current state of a target storage disk to be different from the current states of other storage disks allows for the differentiation of the current state of a specific storage disk from those of other storage disks, thus enabling subsequent identification of that storage disk.

[0073] In some embodiments, before controlling the current state of the target storage disk corresponding to the preset position parameter in each storage disk to be different from the current state of other storage disks, the process may further include:

[0074] Read the list of all in-place storage disks and record the logical index list of all storage disks. An in-place storage disk indicates that it is in the normal power-on and operating process. After recording the logical index list of all in-place storage disks, subsequent control status operations can be performed based on the storage disk's logical index list, and the mapping relationship between the corresponding preset position parameters and target position parameters can be determined based on the storage disk's status.

[0075] The current state of each storage disk refers to the different current states obtained by controlling the storage disk. This current state is differentiated based on the storage disk; for a given storage disk, its state is different from that of other storage disks, while the states of other storage disks can be the same.

[0076] The current state of the target storage disk can be set according to its logical index or physical location. Since the current state of the target storage disk differs from that of other storage disks, its logical index or physical location is determined. The target location parameter, similar to the preset location parameter, can also include either a physical location or a logical index. In other words, the storage disk detection method in this embodiment is equivalent to knowing one of the logical index and physical location, and determining the other corresponding to the storage disk, thereby establishing the mapping relationship between the logical index and physical location of the storage disk. The unknown physical location or logical index of the target storage disk can be determined based on the state of each storage disk obtained by the state reading module 72, thus establishing the mapping relationship from logical index to physical location for that storage disk. For the storage disks in this computer system, by traversing the above operations for each storage disk, the mapping relationship from logical index to physical location for all storage disks can be established, which is equivalent to completing the detection of the storage disk locations in the computer system.

[0077] In some embodiments, controlling the current state of each storage disk may include:

[0078] The current status of the storage disk is controlled by controlling the RAID storage disk array card / HBA host bus adapter card.

[0079] In some embodiments, the current state of the target storage disk corresponding to the preset position parameter in each storage disk is controlled. Unlike the current state of other storage disks, the current state of the storage disk includes at least one of the following: the indicator light status of the storage disk and the power status of the storage disk. The indicator light status refers to controlling the on / off state of the indicator lights on each storage disk, while the power status refers to whether the power to each storage disk is on or off.

[0080] In some embodiments, when the current state of a storage disk includes the status of an indicator light, the corresponding preset position parameter includes a logical index; and controlling the current state of the target storage disk corresponding to the preset position parameter, which differs from the current state of other storage disks, may include:

[0081] Control the on / off state of the indicator light of the target storage disk corresponding to the control logic index, so that the on / off state of the indicator light of the target storage disk is different from the on / off state of other storage disks;

[0082] The target location parameters include physical location; based on the current state of each storage disk, the mapping relationship between the preset location parameters of the target storage disk and the target location parameters is determined, including:

[0083] Based on the on / off state of the indicator lights, the physical location of the target storage disk is determined, and the mapping relationship between the physical location and the logical index is established. The on / off state of the indicator lights on each storage disk indicates whether the indicator light is lit or off; these two states (on / off) allow for differentiation of the indicator light status of each storage disk. In some cases, controlling the current state of the target storage disk corresponding to a preset location parameter to be different from the current state of other storage disks may include:

[0084] The indicator light on the target storage drive is on, while the indicator lights on other storage drives are off; or,

[0085] The indicator light on the target storage disk is off, while the indicator lights on other storage disks are on. In other words, either only the indicator light on the target storage disk is on, or only the indicator light on the target storage disk is off. Regardless of the state, the target storage disk can be distinguished from other storage disks, and its physical location can be determined. Since the storage disks are controlled by logical indices, meaning the logical index of the target storage disk is known, the mapping relationship between the logical index and physical location of each storage disk can be established one by one.

[0086] In some embodiments, when the current state of the storage disk includes the power state, the corresponding preset location parameter includes the physical location; and controlling the current state of the target storage disk corresponding to the preset location parameter, which differs from the current state of other storage disks, may include:

[0087] Power off the storage disk corresponding to one of the physical locations, while keeping the other storage disks powered on. Accordingly, in some embodiments, the target location parameter includes a logical index; and determining the mapping relationship between the preset location parameter of the target storage disk and the target location parameter based on the current state of each storage disk may include:

[0088] Based on the first index list and the second index list, determine the logical index of the storage disk whose power is turned off;

[0089] The second index list is obtained by reading all currently in-place storage disks and recording the records.

[0090] The first index list is obtained by reading all in-situ storage disks and recording their current states before controlling the current states of the target storage disk corresponding to the preset position parameters. When detecting storage disks by power-on / off, the first index list is obtained by traversing and reading all in-situ storage disks before controlling the state of the storage disks. Then, after powering down the target storage disk with the specified logical index, the in-situ storage disks are read again, and the current second index list is recorded. This second index list is different from the first index list in that the logical index of the powered-down storage disk does not exist in the current index list. This allows us to simultaneously determine the logical index of the powered-down storage disk and, based on the power-down state, the physical location of the powered-down storage disk, which is known. This allows us to establish a mapping relationship between logical indexes and physical locations.

[0091] This embodiment provides a storage disk detection device that controls the current state of a target storage disk corresponding to a preset location parameter, ensuring it differs from the current states of other storage disks. It reads the current state of each storage disk and, based on the current state of each disk, determines the mapping relationship between the preset location parameter and the target location parameter of the target storage disk. The target location parameter includes either a physical location or a logical index. By directly identifying the current storage disk state, the device determines the physical location and logical index of the storage disk corresponding to the logical index, enabling real-time adjustment and change of the mapping relationship between the physical location and logical index of the storage disk. This improves the accuracy of identification and enhances the flexibility of computer storage system configuration.

Thus, by directly identifying the current state of the storage disk, the logical index and physical location corresponding to the target storage disk are determined, realizing the real-time adjustment and change of the mapping relationship between the physical location and the logical index of the target storage disk. This avoids the situation where, in computer systems with different configurations, differences in the connection between the storage disk and the hard disk backplane lead to variations in the real-time adjustment of the mapping relationship between the physical location and the logical index of the storage disk are caused by complex system management software, reducing the complexity of the system management software and avoiding identification errors caused by changes in the connection relationship.
