Description

Hard disk management method and computing device

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method for managing a hard disk and a computing device.

Background

The mass storage server generally comprises a plurality of hard disk back plates and a plurality of hard disks, wherein each hard disk is inserted into a slot on the hard disk back plate, and the hard disk back plate is connected with the main board through a back plate signal wire and a serial connection small computer system interface cable, so that a hard disk-to-main board communication link is formed. A baseboard management controller (baseboard manager controller, BMC) on the motherboard manages hard disk information over this link. To more effectively use the hard disk, the server typically also uses redundant array of disk (redundant arrays of independent disks, RAID) cards to array the hard disk. After the RAID card is applied, the SAS cable on the hard disk backplane is no longer directly connected to the motherboard, but is connected to the RAID card SAS interface, and the high-speed serial computer expansion bus standard (peripheral component interconnect express, PCIE) slot of the RAID card inserted on the motherboard may communicate with the BMC through a PCIE bus (or two-line serial (inter-integrated circuit, I2C) bus) to form a communication link from the hard disk to the hard disk backplane to the RAID card to the BMC. Typically, the hard disk, hard disk backplane, and RAID card connections are fixed. However, in reality, due to the requirement of service change, part of the hard disk on the hard disk backboard is changed from being connected to the RAID card to being connected to the SAS interface on the motherboard, so that the direct connection hard disk is changed, or a new RAID card is updated, so that the connection relation between the hard disk, the hard disk backboard and the RAID card is changed. The change of the connection mode does not affect the use of the RAID card, but the BMC cannot identify the connection relation of the hard disk, the hard disk backboard and the RAID card, and after the BMC acquires the hard disk data, the BMC cannot quickly locate the part causing the problem.

Disclosure of Invention

In order to solve the problems in the prior art, embodiments of the present application provide a method, an apparatus, an electronic device, a computer storage medium, and a product containing a computer program for hard disk management, which can quickly locate a component with a problem after a BMC acquires hard disk data.

In a first aspect, an embodiment of the present application provides a method for managing a hard disk, which is applied to a server, where the server includes a motherboard, a hard disk backboard, and a redundant disk array RAID card, where the hard disk backboard is used to mount a plurality of hard disks, and a plurality of slots are provided on the hard disk backboard, where the slots include a first type slot and a second type slot, and the first type slot is in communication with a control chip on the motherboard through the RAID card; the second class of slots are directly communicated with a control chip on the main board; the method comprises the following steps: based on the subgroup number sequence, the control chip issues a lighting command to one of the subgroup number hard disks through the RAID card so as to light the hard disk positioning lamp corresponding to the hard disk, wherein the subgroup number sequence is the number of the RAID card for all the hard disks connected with the first type of slot positions in advance; the method comprises the steps of obtaining slot numbers of a lighted hard disk positioning lamp, wherein the slot numbers are sequencing numbers which are uniformly carried out on first type slots and second type slots in advance by a control chip; and recording the corresponding relation between the hard disk and the subgroup number and the slot number.

In this way, the control chip sends a lighting command to the hard disk connected with the RAID card so as to light the hard disk positioning lamp corresponding to the hard disk, and after the hard disk positioning lamp is lighted, a corresponding relationship can be established between the hard disk and the subgroup number corresponding to the hard disk and the slot number of the slot where the hard disk is located. Therefore, the hard disk can be quickly positioned at the position where the hard disk with the problem is located when the hard disk fails.

As a possible implementation manner, in a case that there are a plurality of RAID cards, each RAID card is connected to the hard disk back plate and the control chip, and each RAID card is connected to at least one slot on the hard disk back plate, the method further includes: each RAID card is connected with a hard disk in a group of first type slots, and each RAID card independently performs subgroup coding on the hard disk in the first type slots connected with the RAID card.

Therefore, under the condition that a plurality of RAID cards are provided, each RAID card can independently number the hard disk connected with the RAID card, namely, each RAID card can manage the hard disk connected with the RAID card, so that all numbering tasks can be prevented from being completed by the control chip, the task amount of the control chip can be reduced, and the working efficiency of the control chip is improved.

As a possible implementation manner, before the control chip issues a lighting command to the hard disk with one subgroup number through the RAID card, the method further includes: the control chip obtains the subgroup number sequence from the RAID card.

As a possible implementation manner, before obtaining the slot number of the lighted hard disk positioning lamp, the method further includes: the control chip acquires slot position information of each slot position on the hard disk backboard; based on the slot information, the control chip uniformly distributes a slot number for each slot.

Therefore, the control chip can uniformly number all the slots on the hard disk backboard, and can clearly know which slot is when the control chip manages the slots of the hard disk backboard.

As a possible implementation manner, in the case that the number of the hard disk back plates is multiple, the slot numbers corresponding to the slots on each hard disk back plate are different.

Therefore, when the control chip carries out unified numbering on the slots on the hard disk backboard, the serial numbers of the slots are ensured to be different. The corresponding relation between the hard disk, the subgroup number and the slot number is ensured to be established, and the conflict possibly caused by the same slot number is reduced.

As one possible implementation manner, the number of the slots on the plurality of hard disk back plates is sequentially arranged.

As a possible implementation manner, the method further includes: when any slot in the first type of slot is inserted into the hard disk, the RAID card sends an inquiry signal to the hard disk in any slot, and the inquiry signal is used for inquiring whether the connection to the hard disk in any slot is successful or not; when the RAID card receives a confirmation signal returned by the hard disk in any slot, the RAID card allocates a subgroup number for the hard disk in any slot; the control chip records the corresponding relation between the hard disk in any slot position and the subgroup number and the slot position number.

Therefore, when a hard disk is newly connected to the hard disk backboard, the hard disk is connected with the BMC through the RAID card, and the BMC can establish the corresponding relation of the hard disk, the subgroup number and the slot number for the hard disk. So that the hard disk can be quickly located when the hard disk is problematic.

As a possible implementation manner, the method further includes: when the hard disk in any slot in the first type of slot is pulled out, the RAID card deletes the subgroup number of the hard disk in any slot recorded by the RAID card; the control chip deletes the corresponding relation between the hard disk and the subgroup number in any slot position recorded by the control chip.

Thus, when the hard disk connected to the RAID card is pulled out, the RAID card can delete the recorded subgroup number of the hard disk. Therefore, when a new hard disk is inserted into the slot position of the hard disk, a corresponding relation can be established for the new hard disk.

As a possible implementation manner, the method further includes: when the second class slot is switched to the first class slot, the RAID card sends an inquiry signal to the target hard disk, and the inquiry signal is used for inquiring whether the connection is successful or not to the target hard disk; the target hard disk is a hard disk connected with the second class of slots; when the RAID card receives a confirmation signal returned by the target hard disk, the RAID card allocates a subgroup number for the target hard disk; the control chip records the corresponding relation between the target hard disk and the subgroup number and the slot number.

In this way, when the hard disk is changed to be connected to the control chip by the RAID card by the direct connection to the control chip, the management method of the hard disk can be changed to the management of the hard disk by the RAID card by the control chip.

As a possible implementation manner, the method further includes: when the first class slot is switched to the second class slot, deleting the subgroup number of the target hard disk recorded by the RAID card; the control chip deletes the corresponding relation between the target hard disk and the subgroup number and the slot number recorded by the control chip.

In this way, the manner in which the hard disk is connected to the control chip through the RAID card is changed to the manner in which the hard disk is directly connected to the control chip, and the management of the hard disk by the RAID card can be changed to the management by the control chip. Thus, the control chip can delete the corresponding relation between the hard disk and the subgroup number and the slot number.

As one possible implementation, the control chip and the RAID card exchange data with each other through a high-speed serial computer expansion bus or a two-row serial bus.

In a second aspect, an embodiment of the present application provides a device for managing a hard disk, disposed on a server, where the server includes a motherboard, a hard disk backboard, and a redundant disk array RAID card, where the hard disk backboard is used to mount a plurality of hard disks, and a plurality of slots are provided on the hard disk backboard, where the slots include a first type slot and a second type slot, and the first type slot is in communication with a control chip on the motherboard through the RAID card; the second class of slots are directly communicated with a control chip on the main board; the device comprises: the transmitting module is used for transmitting a lighting command to the hard disk with one subgroup number through the RAID card based on the subgroup number sequence to light the hard disk positioning lamp corresponding to the hard disk, wherein the subgroup number sequence is the number of the hard disk connected with all the first class slots in advance by the RAID card; the processing module is used for acquiring the slot position numbers of the lighted hard disk positioning lamp, wherein the slot position numbers are the sequence numbers of the first type slot positions and the second type slot positions which are uniformly processed by the control chip in advance; the processing module is also used for recording the corresponding relation between the hard disk and the subgroup number and the slot number.

As a possible implementation manner, in the case that the RAID cards are multiple, each RAID card is connected to the hard disk back plate and the control chip, each RAID card is connected to at least one slot on the hard disk back plate, and the processing module is further configured to: each RAID card is connected with a hard disk in a group of first type slots, and each RAID card independently performs subgroup coding on the hard disk in the first type slots connected with the RAID card.

As a possible implementation manner, before the control chip issues the lighting command to the hard disk with one subgroup number through the RAID card, the processing module is further configured to: the control chip is caused to obtain a subgroup number sequence from the RAID card.

As a possible implementation manner, the processing module is further configured to: before the slot position numbers of the lighted hard disk positioning lamps are obtained, the control chip obtains the slot position information of each slot position on the hard disk backboard; based on the slot information, the control chip uniformly distributes a slot number for each slot.

As a possible implementation manner, the processing module is further configured to: when any slot in the first type of slot is inserted into the hard disk, the RAID card sends an inquiry signal to the hard disk in any slot, and the inquiry signal is used for inquiring whether the connection to the hard disk in any slot is successful or not; when the RAID card receives a confirmation signal returned by the hard disk in any slot, the RAID card allocates a subgroup number for the hard disk in any slot; the control chip records the corresponding relation between the hard disk in any slot position and the subgroup number and the slot position number.

Next, the technical solution provided in the embodiments of the present application will be described.

By way of example, FIG. 1 illustrates a schematic diagram of a computing device. As shown in fig. 1, a motherboard 100, a raid card 102, and a hard disk backplane 103 are included within a computing device. A control chip 101 may be disposed on the motherboard 100, and the control chip 101 may be a BMC101, for example. Wherein, the hard disk backplane 103 and the RAID card 102 may be one or more. The computing device may be a server, for example.

Wherein, at least one slot 1031 is disposed on each hard disk back plate 103. Each slot 1031 may be used in connection with one hard disk 200. For example, the hard disk 200 may be inserted into the slot 1031. A hard disk positioning lamp (not shown in the figure) for positioning the hard disk 200 may be disposed on each slot 1031, and when a hard disk 200 is inserted into a certain slot 1031, the hard disk 200 may light up, extinguish, flash, or change the color of the hard disk positioning lamp on the slot, for example, when the hard disk normally transmits data, the hard disk positioning lamp may always light up a green light, and when the hard disk fails, the hard disk positioning lamp may always light up a yellow light or flash a yellow light. When the hard disk 200 is not inserted into a certain slot 1031, the hard disk positioning lamp is turned on and turned off.

At least one SAS interface 1032 is provided on each hard disk back plate 103. One SAS interface 1032 on each hard disk backplane 103 may be used to connect with one RAID card 102, thereby enabling connection between the hard disk backplane 103 and the RAID card 102. The SAS interface 1032 connected to the RAID card 102 may be connected to each slot 1031 on the hard disk back plate 103 to which the SAS interface belongs. Specifically, SAS interface 1032 may include a plurality of subinterfaces, each subinterface coupled to one slot 1031. It should be appreciated that a SAS interface (not shown) is also provided on the RAID card 102 so that it may be connected to the hard disk back plane via a SAS cable.

In some embodiments, the hard disk backplane may also be directly connected to the BMC101 through the SAS interface 1032, but when the hard disk backplane is directly connected to the BMC101, the BMC may obtain whether the hard disk is in place or not and whether the hard disk has a problem through the CPLD1033 on the hard disk backplane.

A CPLD1033 may be provided on each disk back plate 103. For the CPLD1033 on a certain hard disk back plane 103, the CPLD1033 may read the state information of the hard disk 200 after the hard disk 200 is inserted into the hard disk back plane 103 to which the CPLD1033 belongs. For example, the status information of the hard disk 200 may include whether the hard disk 200 is inserted in a slot, and the status of a hard disk positioning lamp (e.g., whether the hard disk positioning lamp is lit, blinks, whether the color is changed, etc.). In addition, the CPLD1033 may also obtain the slot numbers of the slots 1031 on the hard disk back plate 103 to which the CPLD belongs, and different slot numbers may be used to distinguish different slots. Furthermore, CPLD1033 may be coupled to BMC101, for example, via an integrated circuit bus (inter-integrated circuit, I2C). After a certain CPLD1033 obtains the status information of the hard disk positioning lamps corresponding to the hard disk inserted into the slots on the hard disk backboard 103 to which the CPLD1033 belongs, the BMC101 may obtain the status information of the hard disk positioning lamps of each hard disk 200 connected to the hard disk backboard to which the CPLD1033 belongs from the CPLD1033, and the slot numbers of each slot on the hard disk backboard to which the CPLD1033 belongs.

Each RAID card 102 may send a signal for inquiring whether the hard disk is successfully connected to the hard disk 200 inserted into the slot of the hard disk backplane 103 connected thereto after it establishes a connection with the corresponding hard disk backplane 103. When a connection of a hard disk 200 is successful, the hard disk 200 may return a signal of the successful connection to the corresponding RAID card 102 through the slot into which it is inserted. In this way, the RAID card 102 can acquire information on whether or not the hard disk 200 inserted into the slot of the hard disk back plate 103 connected thereto is successfully connected. In addition, the RAID card may obtain some parameters of the hard disk, for example, capacity of the hard disk, firmware state of the hard disk, temperature of the hard disk, and the like, access time of the hard disk, and the like.

In addition, each RAID card 102 may be connected to the BMC101. For example, the two may be connected by PCIE bus or I2C bus. When the RAID card 102 is connected to the BMC101, the BMC101 may issue a command to the hard disk 200 inserted on the hard disk backplane 103 through the RAID card 102, for example, the BMC101 may control the hard disk 200 to light up a hard disk positioning lamp in a slot position.

In the current scenario, the connection relationship between the hard disk 200, the hard disk backplane 103 and the RAID card 102 is fixed, and when the BMC101 obtains the data of the hard disk 200, the data may sequentially reach the BMC101 via the hard disk 200, the hard disk backplane 103 and the RAID card 102. This fixed connection is recorded in the chip of the BMC101. When the BMC101 obtains that the data transmission of the hard disk 200 is problematic, fault diagnosis can be performed on the components of the whole data link according to the connection relationship recorded in the BMC101, so that the management of the hard disk 200 is realized.

In this embodiment, since the connection relationship between the RAID card and the hard disk back plate is fixed, it is possible to perform failure diagnosis when there is a problem in hard disk data transmission. However, when the connection relationship between the RAID card and the hard disk back plate through the SAS cable is not fixed, for example, when the first hard disk back plate should be connected to the first RAID card and the second hard disk back plate should be connected to the second RAID card, but when the user connects the hard disk back plate to the RAID card, the first hard disk back plate is connected to the second RAID card by mistake, and when the second hard disk back plate is connected to the first RAID card, the fault diagnosis cannot be performed through the connection relationship when the BMC obtains that the hard disk data transmission occurs.

In view of this, the embodiments of the present application provide a method for managing a hard disk, where in the method, when a connection relationship between a RAID card and a hard disk back plate through an SAS cable is not fixed, a BMC may allocate slot identifiers for slots on the hard disk back plate, and a RAID card may allocate a hard disk identifier for a hard disk connected through the hard disk back plate, then, the BMC may send a command for lighting a hard disk positioning lamp associated with a slot on the hard disk back plate to a hard disk corresponding to a certain hard disk identifier through the RAID card, and then determine whether the slot identifier of the slot associated with the lighted hard disk positioning lamp is lighted by reading a CPLD on the hard disk back plate, so as to identify the connection relationship among the hard disk, the hard disk back plate, and the RAID card.

The present method is described in detail below with reference to the accompanying drawings.

By way of example, fig. 2 shows a schematic diagram of a method of hard disk management. The method may be implemented, but is not limited to, by the motherboard of fig. 1. The BMC in FIG. 2 may be BMC101 in FIG. 1, the RAID card in FIG. 2 may be RAID card 102 in FIG. 1, and the hard disk backplane in FIG. 2 may be hard disk backplane 103 in FIG. 1. In this embodiment, the connection relationship between the RAID card and the hard disk back plate is not fixed, and may be that a first RAID card is connected to the first hard disk back plate, a second RAID card is connected to the second hard disk back plate, or that the first RAID card is connected to the second hard disk back plate, and the second RAID card is connected to the first hard disk back plate.

As shown in fig. 2, the hard disk management method may include the steps of:

s201: the BMC acquires slot position information of the slots on each hard disk backboard from the CPLD on each hard disk backboard through the first bus.

In this embodiment, the BMC may read, through the first bus, slot information of each slot on the hard disk backboard where the BMC is located from the CPLD located on the hard disk backboard when the motherboard is powered on each time. Of course, the BMC may also periodically (e.g., every 1 day, 10 days, etc.) read the slot information of the slot of the hard disk backplane from the CPLD located on the hard disk backplane where it is located. Illustratively, the first bus may be a bus to which the BMC is connected to the CPLD, such as: I2C bus, PCIE bus, etc. The number of the hard disk backboard can be one or a plurality of.

For example, referring to fig. 3, two hard disk backplates, namely, hard disk backplate 1 and hard disk backplate 2, are disposed on the motherboard, and CPLDs are disposed on each hard disk backplate. There are 12 slots on the hard disk back plate 1, and 6 slots on the hard disk back plate 2. The hard disk backboard 1 and the hard disk backboard 2 share 18 slots. The BMC on the motherboard may communicate with CPLDs on the hard disk backplanes 1 and 2 via the I2C bus. The BMC may obtain slot information of 12 slots on the hard disk backboard 1 stored in the CPLD by communicating with the CPLD on the hard disk backboard 1. The BMC can obtain slot information of 6 slots on the hard disk backboard 2 stored in the CPLD by communicating with the CPLD on the hard disk backboard 2.

S202: the BMC allocates a slot number for each slot on each hard disk backboard based on the slot information acquired by the BMC, and stores the slot number and the association relation between each slot and the slot number allocated for the BMC.

In this embodiment, the BMC on the motherboard may allocate a number to each slot based on the acquired slot information. In addition, the BMC can record the slot number allocated to each slot and record the association relation between each slot and the slot number allocated to each slot, so that the BMC can quickly position the slot after acquiring the slot number. The BMC allocates a number to each slot, which may be a random number.

For example, referring to fig. 3, the bmc obtains slot information of each of 12 slots on the hard disk back plate 1 and slot information of each of 6 slots on the hard disk back plate 2, and can uniformly allocate slot numbers, namely slot 1, slot 2, slot … and slot 18, to the 18 slot numbers based on the slot information of each of the 18 slots.

In some embodiments, in the case that there are a plurality of hard disk backplates, the slot numbers corresponding to the slots on each hard disk backplate are different.

In this embodiment, when the BMC assigns a slot number to each slot, the assigned slot numbers are all different numbers. Thus, when numbering, the same number is allocated to different slots, and management confusion is prevented. Illustratively, when the BMC assigns a slot number to each slot, it may be a sequential number, such as slot 1, slot 2, …, slot 18.

S203: the RAID card acquires state information of each hard disk connected with the RAID card, wherein the state information comprises whether the hard disk is successfully connected.

In this embodiment, the RAID card is connected to the hard disk back plate, and a hard disk is connected to a slot of the hard disk back plate (the connection mode may be plug-in, that is, the hard disk is inserted into the slot). At this time, the RAID card is connected with the hard disk through the hard disk backboard. The RAID card may obtain, when the device is powered on, status information of the hard disk inserted in the slot of the hard disk backplane, where the status information may include whether the hard disk is in place (i.e., whether the hard disk has been inserted in the slot). When the hard disk is in place (i.e., the hard disk is inserted in a slot), the RAID card may obtain information as to whether the connection with the hard disk was successful. When the connection is successful, the RAID card can acquire the state information of the hard disk connected with the RAID card.

S204: the RAID card distributes a subgroup number for each hard disk connected with the RAID card to form a subgroup number sequence. The subgroup sequence is stored.

In this embodiment, when the RAID card obtains connection information of the hard disk connected to the RAID card, the connection information may be recorded, and based on the connection information, a subgroup number is allocated to each hard disk, where the subgroup numbers form a sequence, which may be referred to as a subgroup number sequence. The connection information may include that the RAID card is connected to an SAS interface on the hard disk back plate through an SAS cable, a sub-interface of the SAS interface is connected to a slot on the hard disk back plate, and a hard disk is connected in the slot. In addition, the RAID card can store the association relation between the hard disk connected with the RAID card and the subgroup number, so that the RAID card can know the hard disk associated with the subgroup number based on the subgroup number. Illustratively, the subgroup numbers are logical numbers, not physically present numbers, nor reflect the actual slot positions of the hard disk on the hard disk back plate.

For example, in fig. 3, there are a RAID card 2 and a hard disk back plate 1 on the motherboard, and there are 12 slots on the hard disk back plate 1, but only 6 slots have the hard disk inserted therein. At this time, the hard disks connected to the RAID card 2 are the hard disks 1 to 6 on the hard disk backplane 1, and the subgroup sequences allocated to the hard disks by the RAID card 2 are S1, S2, …, S6. Wherein S1 is a subgroup sequence allocated by the RAID card to the hard disk 1, S2 is a subgroup sequence allocated by the RAID card to the hard disk 2, …, and S6 is a subgroup sequence allocated by the RAID card to the hard disk 6.

In some embodiments, the number of RAID cards is multiple, and in the case that there are multiple RAID cards, each RAID card is connected to the hard disk backplane and the control chip, at this time, each RAID card is connected to a hard disk in a first group of slots, and each RAID card separately performs subgroup numbering on the hard disk in the first group of slots connected to itself. The first type of slot refers to a slot that can communicate with the BMC on the motherboard through a RAID card.

In this embodiment, there are multiple RAID cards, each of which is connected to the hard disk backplane and the BMC, and at this time, the RAID cards may individually perform subgroup numbering for the hard disk connected thereto. For example, in fig. 3, there are 2 RAID cards on the motherboard, namely RAID card 1 and RAID card 2; the two hard disk back plates are respectively a hard disk back plate 1 and a hard disk back plate 2. Wherein, there are 12 slots on the hard disk backboard 1, but only insert the hard disk in 6 slots; the hard disk backboard 2 is provided with 6 slots, and the hard disk is inserted into each of the 6 slots. At this time, the RAID card 2 is connected to 6 hard disks on the hard disk backplane 1 through the hard disk backplane 1, and the RAID card 2 assigns subgroup numbers S1, S2, …, and S6 to the 6 hard disks. The RAID card 1 is connected to 6 hard disks on the hard disk backplane 2 through the hard disk backplane 2, and the RAID card 1 assigns subgroup numbers S1, S2, …, and S6 to the 6 hard disks.

S205: the BMC acquires a subgroup number sequence stored by the RAID card from the RAID card, and stores the association relation between the subgroup number sequence and the RAID card.

In this embodiment, after the RAID card allocates a subgroup number to the hard disk connected thereto, the RAID card may send a subgroup number sequence formed by the allocated subgroup numbers to the BMC. Thus, the BMC can acquire the subgroup number allocated by the RAID card for the hard disk connected with the RAID card and store the subgroup number sequence. When the BMC stores the subgroup number sequence, the BMC may further store an association relationship between the RAID card and the subgroup number allocated to the RAID card, so that the BMC may obtain, through a certain subgroup number, the RAID card associated with the subgroup number.

For example, the RAID card 1 performs allocation identification on the hard disk 1 to the hard disk 6 connected thereto, and obtains a subgroup number sequence S1, S2, …, S6. Wherein S1 is a subgroup sequence allocated by the RAID card to the hard disk 1, S2 is a subgroup sequence allocated by the RAID card to the hard disk 2, …, and S6 is a subgroup sequence allocated by the RAID card to the hard disk 6. RAID card 1 may send the subgroup number sequence S1, S2, …, S6 to the BMC. After the BMC acquires the subgroup serial number sequence, the subgroup serial number sequence can be stored; meanwhile, the BMC may store an association relationship between the subgroup sequence and the RAID card 1.

S206: when the RAID is multiple, the BMC controls the hard disk associated with the j subgroup number allocated by the i RAID card to light the hard disk positioning lamp of the slot position of the hard disk through the i RAID card, and the initial values of i and j are both 1. The lighting may be that the hard disk indicates that the hard disk positioning lamp is changed from a normally-off state to a normally-on state, or that the hard disk positioning lamp is changed from the normally-off state to a blinking state.

In this embodiment, the BMC may control, through the ith RAID card, the hard disk associated with the jth subgroup number allocated to the ith RAID card, so that the hard disk associated with the jth subgroup number may light the hard disk positioning lamp of the slot position where the hard disk associated with the jth subgroup number is located. Wherein the initial values of i and j are both 1. For example, the BMC may send an instruction to the ith RAID card to instruct the ith RAID card to control the hard disk associated with its assigned jth subgroup number. Then, the ith RAID card may send an instruction to the hard disk associated with the jth subgroup number allocated to the ith RAID card, so as to instruct the hard disk associated with the jth subgroup number allocated to the ith RAID card to light the hard disk positioning lamp of the slot position of the hard disk. When the hard disk associated with the jth subgroup number acquires the instruction sent by the RAID card connected with the hard disk, the hard disk associated with the jth subgroup number can light the hard disk positioning lamp of the slot position of the hard disk.

For example, with continued reference to fig. 3, the bmc may send an instruction to the RAID card 1, where the instruction may be used to instruct the RAID card 1 to control the hard disk 1 associated with its assigned 1 st subgroup number (i.e. S1) to light the hard disk positioning light of the slot in which the hard disk 1 is located. Next, the RAID card 1 may send an instruction to the hard disk 1 to instruct the hard disk 1 to light the hard disk positioning light in the slot. Finally, the hard disk 1 can light the hard disk positioning lamp at the groove position.

S207: and the BMC acquires the slot number of the slot where the lighted hard disk positioning lamp is located through the CPLD on the hard disk backboard connected with the ith RAID card.

In this embodiment, after the hard disk associated with the jth subgroup number lights the hard disk positioning lamp of the slot position, the CPLD on the hard disk backboard to which the slot position belongs can read the slot position number of the slot position to which the hard disk positioning lamp belongs. The CPLD may then actively send the slot number to the BMC so that the BMC obtains the slot number. In addition, the BMC may actively read the information in the CPLD to obtain the slot number.

For example, the hard disk 1 associated with the first slot on the hard disk back plate 2 lights up the hard disk positioning light of the first slot, the slot of the first slot being denoted as slot 13. At this time, the BMC may obtain the slot 13 associated with the turned-on hard disk positioning lamp through the CPLD on the hard disk backboard 2.

S208: the BMC records the corresponding relation between the hard disk and the subgroup number corresponding to the hard disk, the slot number of the slot where the hard disk is positioned and the RAID card connected with the hard disk, wherein the subgroup number corresponds to the hard disk.

In this embodiment, the jth hard disk lights up the hard disk positioning lamp of its associated slot, and at this time, the BMC may obtain, through the CPLD on the hard disk back plate, the slot number of the slot where the hard disk positioning lamp is turned up is located. At this time, the BMC may correlate the hard disk with the subgroup number corresponding to the hard disk, and the slot number of the slot where the hard disk is located.

For example, the hard disk with the subgroup number S2 lights up the hard disk positioning lamp of the slot 14, and at this time, the BMC obtains, through the CPLD on the hard disk back plate, the slot number of the slot where the hard disk with the hard disk positioning lamp is lighted up as the slot 14. At this time, the BMC may record the corresponding relationship between the hard disk and the subgroup numbers S2 and slots 14.

S209: the BMC makes j=j+1 and determines whether j is greater than the number of subgroup numbers allocated to the i-th RAID card.

In this embodiment, after the BMC determines the j-th hard disk connected to the i-th RAID card, the mapping relationship (i.e. the corresponding relationship between the hard disk and the subgroup number corresponding to the hard disk and the slot number of the slot where the hard disk is located) of the next (i.e. j+1th) hard disk connected to the current RAID card may be determined. At this time, it is necessary to determine whether the hard disk with the association relationship determined is the last hard disk connected to the current RAID card, i.e. let j=j+1, and determine whether j is greater than the number of subgroup numbers allocated to the current RAID card. When the determination result is no, it indicates that the association relationship between the slot identifier, the RAID card and the hard disk is not yet determined by the current hard disk, and at this time, execution may return to S206. And when the judgment result is yes, the fact that all the hard disks connected with the current RAID card have determined the association relationship of the slot number, the subgroup number, the RAID card and the hard disk is indicated. At this time, the association relationship between the hard disk on the next RAID card and the slot number, the RAID card, and the subgroup number may be determined, that is, S210 is performed.

S210: the BMC makes i=i+1 and determines whether i is greater than the number of RAID cards connected to the BMC.

In this embodiment, the BMC has obtained the association relationship between the slot numbers of all the hard disks connected to the ith RAID card and the subgroup number, and may obtain the association relationship of the hard disk on the next RAID card. At this time, it is necessary to determine whether or not the RAID cards have all determined the association relationship, that is, in the case where i=i+1, it is determined whether or not i at this time is greater than the number of RAID cards. If the determination result is no, it indicates that the association relationship between the hard disk and the slot number, the RAID card, and the subgroup number is not yet determined by the hard disk connected to the current RAID card, and step S211 may be executed. When the judgment result is yes, the fact that all RAID cards connected with the BMC have determined the association relation between the hard disk and the slot number, the association relation between the RAID cards and the subgroup number can be achieved, and the method can be ended.

S211: the BMC will initialize the value of j and return to executing S206.

In this embodiment, the value of j may be initialized, and the process returns to S206.

In some embodiments, when any one of the first type of slots is inserted into the hard disk, the RAID card sends an interrogation signal to the hard disk in any one of the slots, where the interrogation signal is used to interrogate the hard disk in any one of the slots as to whether the connection was successful; when the RAID card receives a confirmation signal returned by the hard disk in any slot, the RAID card allocates a subgroup number for the hard disk in any slot; the BMC records the corresponding relation between the hard disk in any slot position and the subgroup number and the slot position number.

In this embodiment, when one slot is empty, a hard disk may be inserted into the slot. When a hard disk is inserted, the RAID card may send an interrogation signal to the inserted hard disk to interrogate whether the connection was successful. After the RAID card receives the acknowledgement signal returned from the hard disk, the RAID card may assign a subgroup number to the hard disk (i.e. execute step S204). After assigning the subgroup number to the hard disk, the subsequent operations may refer to steps S205-S212, which are not described herein.

In some embodiments, when the hard disk in any one of the first class of slots is unplugged, the RAID card deletes the subgroup number of the hard disk in any one of the slots recorded by the RAID card; the BMC deletes the corresponding relation between the hard disk and the subgroup number and the slot number in any slot recorded by the BMC.

In this embodiment, when the hard disk connected to the RAID card is pulled out, the RAID card may delete the recorded subgroup number corresponding to the hard disk. Meanwhile, the RAID card can inform the BMC of the deleted subgroup numbers, and the BMC deletes the corresponding relationship between the hard disk corresponding to the subgroup numbers and the slot numbers.

In some embodiments, when the second type slot is switched to the first type slot, the RAID card sends an interrogation signal to the target hard disk, where the interrogation signal is used to interrogate the target hard disk whether the connection was successful; the second class slot is a slot which is directly communicated with the BMC, and the target hard disk is a hard disk connected with the second class slot; when the RAID card receives a confirmation signal returned by the target hard disk, the RAID card allocates a subgroup number for the target hard disk; the BMC records the corresponding relation between the target hard disk and the subgroup number and the slot number.

In this embodiment, the connection mode of the hard disk is changed from directly connecting the BMC through the hard disk back plate to connect the BMC through the RAID card. This is equivalent to inserting a new hard disk into the hard disk backplane connected to the RAID card, and the specific management process is described in detail in the foregoing description of inserting any slot of the first type slots into the hard disk, which is not described herein.

In some embodiments, when the first class slot is switched to the second class slot, the RAID card deletes the subgroup number of the target hard disk recorded by the RAID card; the BMC deletes the corresponding relation between the recorded target hard disk and the subgroup number and the slot number.

In this embodiment, the connection mode of the hard disk is changed from the connection of the BMC through the RAID card to the direct connection of the BMC through the hard disk back plate. This is equivalent to the fact that the hard disk in any one of the first type of slots is pulled out, and the specific management process refers to the related description of the pulling out of the hard disk in any one of the first type of slots, which is not repeated here.

After the BMC records the connection relation between all RAID cards and all hard disks, when the BMC cannot acquire hard disk data, the BMC can quickly locate the problematic component and prompt the problematic component to a user. Specifically, the BMC may first obtain whether a problem occurs in the hard disk. The hard disk can be checked by a short self-checking mode, the RAID card is informed by the hard disk backboard after the short self-checking finds that the hard disk is problematic, and then the RAID card informs the BMC of the wrong subgroup number of the hard disk through the SAS cable. Or the BMC sends detection information to the hard disk through the RAID card, the hard disk detects itself after receiving the detection information, and returns error state information to the BMC after finding a problem. After the BMC acquires the subgroup numbers of the hard disks, the slot numbers of the slots of the hard disks with problems can be determined according to the established association relationship among the slot numbers, the RAID cards and the subgroup numbers of the hard disks, and the user is informed of the slot numbers of the slots of the hard disks with problems. The RAID card can also acquire the parameters of the hard disk, and can know what problems the hard disk has, such as overhigh temperature or over-high rotating speed of the hard disk. When the component with problems is not a hard disk, the BMC can detect the phy error code of the whole data link, the error code refers to the number with errors when data is transmitted in the data link, if the phy error code in the data link increases or grows too fast, the BMC indicates that the SAS cable in the data link has problems, and the BMC can prompt a user on the basis of the recorded connection relation which connected SAS cable between the hard disk backboard and the RAID card has faults.

According to the embodiments, the BMC performs uniform allocation identification on the hard disk slots on all the hard disk backboard, each RAID card performs allocation identification on the hard disk connected with the control of the BMC, the BMC can light the hard disk positioning lamps of the hard disk one by one according to the hard disk identifications by issuing instructions to the RAID cards, and meanwhile, the BMC acquires the slots of the hard disk where the hard disk positioning lamps are light through the CPLD chip on the hard disk backboard, so that the connection relation of the hard disk (subgroup number), the hard disk backboard (slot number) and the RAID card can be accurately acquired, and when the hard disk data is read out, the BMC can quickly acquire the positions of the error components (such as the hard disk or the SAS cable) according to the corresponding mapping relation.
