Hot plug of storage devices is often frequently performed during hardware maintenance of computing devices, and currently, aiming at NVMe hard disks, a notification type hot plug scheme is required. That is, before extracting the NVMe hard disk, the user needs to issue a command to unload the NVMe hard disk through the operating system before extracting the NVMe hard disk manually. However, this scheme for issuing commands is complex and prone to error, and requires the user to be familiar with the operating system commands, so that the scheme has a high technical threshold requirement.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In order to clearly describe the technical solution of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", etc. are used to distinguish the same item or similar items having substantially the same function and effect, and those skilled in the art will understand that the terms "first", "second", etc. are not limited in number and execution order.

Related terms related to the embodiments of the present application will be explained first.

1. Hot plug: the plug-and-play operation method refers to external devices such as a board card, a daughter card and a hard disk in the computing device, and the operations such as plug-in and pull-out are performed under the condition that the computing device is not reset and powered down, but the normal operation of the computing device is not affected, and the plug-and-play effect is realized.

2. NVMe: the non-volatile memory host controller interface specification (non-volatile memory express) is a new generation of logical device interface specification. The NVMe hard disk is a storage device conforming to the NVMe protocol, and can be directly communicated with the processor through a high-speed serial computer expansion bus standard (PERIPHERAL COMPONENT INTERCONNECT EXPRESS, PCIe) bus, so that the communication efficiency is high.

As described in the background, hard disks are one of the most common and important accessories in computing devices, and it is often necessary to plug NVMe hard disks hot-swapped during the operation and maintenance of the computing device. The current hot plug scheme of the NVMe hard disk mainly comprises violent hot plug and notification hot plug. Violent hot plug requires support of Volume MANAGEMENT DEVICE (VMD) functions, which is a deployment solution for storage devices that supports hot upgrade and replacement (replacement may include plug-in, plug-out) of NVMe hard disks from the PCIe bus without shutting down the computing device, while standardizing the flow of hard disk lighting, which may help users to more quickly identify the working state of NMVe hard disks. However, the VMD function requires a user to pay for use and requires a specific model of operating system to use the VMD function.

The notification hot plug may not require support of the VMD function, but may require the user to issue a command to the operating system to perform hard disk uninstallation before the hard disk is unplugged. The scheme of issuing the command is complex in process and easy to make mistakes, so that a user is required to be familiar with the command of the operating system, and correct input of the command is ensured. In addition, in the process of issuing the command, the user is required to explicitly uninstall the slot identifier (slot IDentity) of the hard disk on the operating system, so that the operating system can directionally uninstall the hard disk. But the slot IDs of different models have different corresponding relations, and users are required to inquire the corresponding relations, so that the operation complexity is further improved.

Based on this, the embodiment of the application provides a management method of a hard disk, which is characterized in that a management controller displays the distribution condition of at least one slot position in a computing device on the computing device and the in-place condition of the hard disk in each slot position. The user can clearly determine the location of the hard disk to be offloaded through the interface display. Further users can select the slot position of the hard disk to be unloaded through interface operation. According to the slot position specified by the user, the management controller can execute related unloading operation on the hard disk on the slot position, so that the hard disk is unloaded. The interface visual operation mode does not need the user to issue commands step by step, so that the use threshold of the user can be reduced, the time of manual configuration can be reduced, and the hard disk plug efficiency is improved. In addition, by replacing manual configuration, the configuration accuracy can be ensured, and the occurrence of error operation of configuration can be reduced.

It should be understood that the method for managing a hard disk provided in the embodiment of the present application may be applicable to an NVMe hard disk, or may be applicable to other hard disks that need to be unloaded by a command.

The embodiments of the present application will be described in detail below with reference to the drawings attached to the specification.

The technical scheme provided by the embodiment of the application can be applied to the computing equipment, and the computing equipment can be a blade server, a high-density server, a rack server or a high-performance server and the like. Fig. 1 is a schematic system architecture diagram of a computing device, as shown in fig. 1, including a processor, a basic input output system (basic input output system, BIOS) chip, a management controller, at least one slot, and a complex programmable logic device (complex programmable logic device, CPLD). The processor, the BIOS chip and the management controller can be deployed on the motherboard, and the CPLD and at least one slot can be deployed on the backplane. The processor is respectively connected with the BIOS chip, the management controller and the CPLD, the management controller is connected with the CPLD on the backboard, and the CPLD is connected with at least one slot position.

Wherein the processor runs on an Operating System (OS), and the processor can call the BIOS in the BIOS chip and run.

Wherein the management controller is a non-business management unit. For example, a management controller that is completely independent of the operating system of the computing device may communicate with the BIOS and operating system through an out-of-band management interface of the computing device may remotely maintain and manage the computing device through a dedicated data channel. The processor may include a central processing unit (central processing unit, CPU) including one or more CPU cores, and operations of the CPU to process data are performed by the CPU cores. The more CPU cores included in the CPU, the faster the data is processed.

The CPLD can manage the power on and off of each slot, and each slot can support the plugging of the hard disk.

BIOS, a set of programs that solidify onto the BIOS chip of a motherboard within a computing device. The BIOS has the main function of providing the bottommost and most direct hardware setting and control for the computing device, and can be used for initializing and detecting various hardware devices in the starting process of the computing device. The BIOS program is stored in a BIOS chip on the motherboard.

An operating system is a computer program that manages and controls the hardware and software resources of a computing device, and any other software must run with the support of the operating system. After the server is powered on, the processor calls the BIOS program to start a series of operations such as self-checking, initializing and the like, and then guides the operating system to start, so that a user can normally use the computing device.

By way of example, the management controller may include a management unit for the running state of the computer, a management system in a management chip external to the processor, a computing device motherboard management unit (baseboard management controller, BMC), a system management module (SYSTEM MANAGEMENT mode, SMM), and the like. It should be noted that the embodiments of the present application are not limited to the specific form of the management controller, and the above is merely exemplary. In the following embodiments, only a management controller will be described as an example of a BMC.

A BMC is a stand-alone system that does not rely on other hardware (e.g., CPU, memory, etc.) on a computing device nor on a BISO, operating system, etc., but rather the BMC may interact with the BIOS or operating system to enable management of the computing device. In addition, the BMC also provides a remote operation function, a user can access an operation interface of the BMC through a network, can know the running state of the computing device through the operation interface, and can issue commands to the computing device through the operation interface.

It should be noted that servers of different companies have different names for BMCs, for example, some companies are called BMCs, some companies are called iLO, and another company is called iDRAC. Either the BMC or iLO or iDRAC may be understood as a BMC in embodiments of the invention.

It should be noted that, the system architecture and the application scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is also applicable to similar technical problems.

As shown in fig. 2, an embodiment of the present application provides a method for managing a hard disk, which may include the following steps:

s201, the management controller displays a first interface.

Wherein the first interface includes a distribution of at least one slot on the computing device and an in-place condition of the hard disk in each slot.

In the embodiment of the application, a user can check the running state of the computing device or realize the control of the computing device by accessing the management controller of the computing device. The management controller may display a first interface that presents to the user the slot distribution of the computing device, as well as the on-site status of the hard disk (i.e., whether to plug).

For example, fig. 3 is a schematic diagram of a first interface according to an embodiment of the present application. As shown in FIG. 3, the first interface includes a front view of the computing device, showing six slots, slot 1-slot 6, respectively. Wherein, the hard disk is inserted into the slot 1-5 (i.e. in place), and the slot 6 is not inserted into the hard disk (i.e. out of place).

S202, the management controller responds to the operation of the first slot position in the first interface to display the second interface.

The first slot is one slot of at least one slot, in which the hard disk is inserted, and the second interface comprises a first control. The first control is used for unloading the hard disk on the first slot.

It can be seen that the management controller enables a user to intuitively determine the number of slots, the distribution condition and the in-place state by displaying the first interface. In the embodiment of the application, if the user needs to execute the unplugging operation on the hard disk on a certain slot (the first slot), the clicking operation can be executed on the first slot on the first interface. In response to the operation, the computing device further displays a second interface. The second interface comprises a first control for unloading the hard disk on the slot.

In one implementation, the second interface further comprises: slot identification (slot ID) of the first slot and related information of the hard disk on the first slot. Wherein the related information may include at least one of: health status, disc type, capacity size, manufacturer, wear rate, estimated life.

It should be understood that the computing device may read the running condition of the hard disk during the running process, and display the running condition to the user through the management controller, so as to facilitate the management of the user. In addition, slot IDs corresponding to different slots can be configured in the BMC in advance and displayed when the second interface is displayed, so that a user can conveniently maintain the computing device.

For example, fig. 4 is a schematic diagram of a second interface according to an embodiment of the present application. Referring to fig. 3, as shown in fig. 4, the hard disk in the slot 3 is required to be pulled out by the user, so that after the user clicks the slot 3 in the first interface, the second interface in fig. 4 is displayed. The second interface shows the slot identification of the slot 3 corresponding to the operating system and the information of the hard disk in the slot. For example, the location is slot 10, the health status is normal, the disk type is NVMe SSD, the capacity is 1.92T, the manufacturer is xFusion, the wear rate is 0%, and the estimated lifetime is 60 months. Meanwhile, the second interface also comprises a first control (namely, a control for removing the hard disk in the figure).

It should be understood that the second interface may be displayed on the first interface in the form of a floating window, or may be a separate interface, which is not particularly limited in the embodiment of the present application. Fig. 4 illustrates a second interface in the form of a floating window according to an embodiment of the present application.

And S203, the management controller responds to the operation of the first control, controls the CPLD to power down the first slot and controls the processor to unload the drive of the hard disk, and then outputs first prompt information.

The first prompt message is used for prompting that the hard disk on the first slot position can be pulled out.

In the embodiment of the application, after the user clicks the first control in the second interface, the management controller can respond to the clicking operation, on one hand, control the CPLD to power down the first slot, and on the other hand, control the processor to unload the hard disk to execute the unloading operation, complete the unloading flow before the hard disk is pulled out, and then output the first lifting information to inform the user that the hard disk on the first slot is pulled out.

The first prompt information may be output by directly displaying the prompt information on a display interface of the BMC to indicate that the user hard disk is removable, or by controlling the lighting condition of the lamp on the back plate to indicate that the user hard disk is removable, or by combining the two modes to prompt, which is not particularly limited in the embodiment of the present application. For example, the user may observe the status of the hard disk indicator, and if the green indicator is turned off and the yellow indicator is flashing (0.5 Hz), it indicates that the hard disk has been unloaded, and the user may currently pull out the hard disk slowly.

It should be understood that if the hard disk is directly pulled out while the read/write operation is being performed, damage to the hard disk may result. Therefore, the hard disk is powered down and the drive is unloaded before unloading, and is pulled out after the working state is finished, so that the service life of the hard disk can be effectively prolonged, and the data loss is avoided.

In some implementations, as shown in fig. 5, controlling the CPLD to power down the first slot in S203 may be implemented as follows:

s501, the management controller sends a first instruction to the CPLD. The first instruction comprises a slot identification of the first slot.

S502, the CPLD responds to the first instruction and electrifies the first slot according to the slot identification.

For the above S501-S502, after the first control is clicked by the user, the management controller of the computing device may determine, in response to the clicking operation of the user, a slot identifier of the slot clicked by the user, and send a first instruction including the slot identifier to the CPLD, so as to instruct the CPLD to power down the first slot. Correspondingly, the CPLD responds to the first instruction, stops supplying power to the first slot according to the slot identification, and completes the power-down flow. In addition, the CPLD may feed back a response to the management controller indicating that power down is complete.

In some implementations, as shown in fig. 6, the controlling the processor to unload the hard disk in S203 may be implemented as follows:

S601, the management controller sends a second instruction to the processor. The second instruction comprises a slot identification of the first slot.

S602, the processor responds to the second instruction, and the hard disk drive is unloaded according to the slot position identification.

For S501-S502 described above, the management controller may send a second instruction including a slot identification. Accordingly, the processor, in response to the second instruction, runs the operating system to execute the following commands: echo n >/sys/bus/pcb/slots/slot ID/power to complete the drive offloading of the hard disk on the first slot. The slot ID is a slot identifier of the first slot.

As one possible implementation, the processor may accomplish the unloading of the hard disk drive under the control of the CPLD. After the CPLD completes the power-down operation on the first slot, the CPLD can send an interrupt signal to the processor through an interrupt controller of the CPLD, wherein the interrupt signal is used for indicating the processor to run an operating system to unload the drive of the hard disk. Further, the processor may run the operating system for drive offloading in response to the interrupt signal. In addition, the processor may feedback a response to the management controller indicating that the drive offload is complete.

In some scenarios, the operating system may initiate an interrupt distribution service (irqbalance services) to optimize interrupt distribution. The service may cause the computing device to distribute interrupts evenly to the various CPUs to enhance the performance of the computing device. In the scene of hard disk plug, the hard disk can generate interrupt signals in the normal use process, and the computing equipment needs to reasonably distribute the interrupt signals to each CPU for processing. When the hard disk is pulled out, the hardware environment of the computing device is changed, which may cause uneven allocation of interrupt resources, so that the interrupt allocation service needs to be restarted, so that the computing device reallocates the interrupt resources according to the new hardware environment, and full utilization of computing performance of the computing device is ensured.

Therefore, the method for managing the hard disk provided by the embodiment of the application further comprises the following steps a-b:

And a step a, detecting whether an operating system running by the processor starts interrupt distribution service.

And b, under the condition that the operating system enables the interrupt distribution service, the management controller controls the operating system running by the processor to restart the interrupt distribution service.

For steps a and b above, the management controller may send instructions to the processor to cause the processor to run the operating system to detect whether the operating system is currently initiating interrupt distribution services. If enabled, this indicates that the service needs to be restarted. The processor runs the operating system to restart the interrupt distribution service, so that the correct distribution of interrupt resources is ensured.

It should be understood that, in the embodiment of the present application, the execution sequence of the power-down process, the drive unloading process, and the interrupt distribution service restart process is not specifically limited, and may be sequentially executed or may be simultaneously executed.

In some scenarios, after S201, as shown in fig. 7, the method for managing a hard disk according to the embodiment of the present application further includes the following S701-S702.

S701, the management controller responds to the operation of the second groove position in the first interface to display a third interface.

The second slot is one slot of the at least one slot, which is not connected with the hard disk in an inserted mode, and the third interface comprises a second control, wherein the second control is used for installing the hard disk on the second slot.

S702, responding to the triggering operation of the second control, and outputting second prompt information.

The second prompt information is used for indicating that the hard disk can be inserted into the second slot.

For the above S701-S702, if the user needs to plug in the hard disk on a certain slot (the second slot), the clicking operation may be performed on the second slot on the first interface. In response to the operation, the computing device further displays a third interface. The third interface comprises a second control for installing the hard disk on the slot. Further, the user clicks the second control, and the computing device can determine that the user needs to install the hard disk on the slot, and then output second prompt information to indicate that the user can insert the hard disk.

For example, fig. 8 is a schematic diagram of a third interface provided in an embodiment of the present application, as shown in fig. 8, a hard disk is not inserted into the slot 6, and after a user clicks the slot 6 in the first interface, the third interface in fig. 8 is displayed. The third interface shows the corresponding slot identification of slot 3 on the operating system, and a third control (hard disk mounted control).

Further, after the user inserts the hard disk, the computing device may detect the state of the hard disk and output a prompt message to prompt the user of the state of the hard disk. For example, by means of lighting prompt, the green indicator lamp is constant and the yellow indicator lamp is turned off, so that the hard disk is in place and has no fault, and the user can use the hard disk normally. Or the CPLD informs the management controller that the hard disk is inserted into the second slot, and the management controller prompts the user that the hard disk is in place (i.e. updates the first interface) through the display interface.

In some scenarios, a user may need to make a switch in the switch state of the VMD function. In the related art, if a user opens a VMD function to be started, the user needs to operate the computing device to enter a BIOS interface, find configuration parameters of the VMD function by searching step by step, and save the configuration and restart the computing device after setting an enable VMD function to enable the configuration to take effect. Similarly, if the user opens the VMD function to be closed, the computing device needs to be operated to enter the BIOS interface, the configuration parameters of the VMD function are found by searching step by step, and after the closing (disabled) VMD function is set, the configuration is saved and the computing device is restarted to enable the configuration to be effective.

In addition, under the condition of closing the VMD function, the user also needs to additionally configure kernel parameters to ensure the correct operation of the hard disk on the operating system. The process of configuring the kernel parameters requires a user to log in an operating system, after finding out a corresponding configuration file, newly adding a configuration command to the content of the configuration file, and then restarting the computing device after saving so as to enable modification to be effective. It can be seen that this manual configuration is extremely inconvenient to operate, affecting the maintenance efficiency of the computing device. Moreover, manual configuration is unavoidably subject to error, which can result in abnormal operation of the computing device.

Based on this, the method for managing a hard disk provided by the embodiment of the present application may also realize convenient switching of the switch state of the VMD function, which is specifically described as follows:

Before S201, as shown in fig. 9, the method for managing a hard disk further includes: and S901, displaying a fourth interface by the management controller. Wherein the fourth interface includes a switch state of the VMD function. It should be appreciated that in the case of closing the VMD function, the hard disk does not support violent hot plug, and the user needs to uninstall the hard disk by command. Therefore, in the case of executing S901, the above S201 specifically includes: and when the VMD function is in a closed state, the management controller displays a first interface. The method is convenient for a user to select the hard disk to be unloaded through the first interface without manually issuing a command.

Wherein, the fourth interface may include a third control and/or a fourth control. Wherein the third control is used to turn on the VMD function. The fourth control is used to turn off the VMD functionality. It should be appreciated that BIOS configuration parameters are typically stored in the BIOS chip, and the BMC may access this memory through the I2C bus, reading the switch state of the VMD function in the current BIOS. When the VMD function is turned off, the user may click on the third control to turn on, and when the VMD function is turned on, the user may click on the third control to turn off.

For example, fig. 10 is a schematic diagram of a fourth interface according to an embodiment of the present application. As shown in fig. 10, the switch state of the current VMD function of the computing device is shown in an off state (in the case of a default configuration). Meanwhile, a prompt message of "the current configuration can install the hard disk, please confirm whether the VMD needs to be enabled", and a control (fourth control) including a control (third control) to open the VMD and a control (fourth control) to close the VMD are also included. It should be appreciated that the fourth interface may not display the third control, or may display the third control but the user cannot click when the VMD function is in an on state. Likewise, the fourth interface may not display the fourth control when the VMD functionality is in the off state, or the fourth control may be displayed but not clicked by the user. The embodiment of the application does not limit the specific display mode.

Fig. 11 is a schematic flow chart of starting VMD function according to an embodiment of the present application. As shown in fig. 11, after S901, the steps of:

s1101, in a case where the switch state of the VMD function is the off state, the management controller configures a first configuration parameter of the BIOS chip in response to an operation on the third control, and restarts the computing device.

The first configuration parameter is used for indicating that the VMD function is in an on state.

S1102, outputting third prompt information.

The third prompting information is used for prompting the computing device to support hot plug of the hard disk.

For the above S1101-S1102, when the user needs to turn on the VMD function, the third control in the fourth interface is clicked. In response to this operation, the management controller performs the following: 1. the management controller sends a third instruction to the processor; 2. the processor responds to a third instruction, and runs the BIOS to acquire a first configuration parameter from the management controller; 3. the processor runs the BIOS and modifies the target option of the BIOS chip into a first configuration parameter; the target option is the switch state of the VMD function. After the modification is completed, the processor informs the management controller, which controls the computing device to restart to validate the first configuration parameters. After confirming that the validation is completed (the management controller reads new BIOS parameters after restarting to confirm whether the validation is completed), a third prompt message is output on the display interface, and the third prompt message is used for prompting the user that the VMD function is started, so that the plug-and-play of the hard disk can be supported.

That is, when the user clicks the third control, the management controller generates the first configuration parameter corresponding to the third control, and sends the instruction to notify the processor. Further, the processor runs the BIOS to send an IPMI command to the management controller via an intelligent platform management interface (INTELLIGENT PLATFORM MANAGEMENT INTERFACE, IPMI), and the management controller responds to the command to send a first configuration parameter to the BIOS chip via a communication channel (configured by BT over eSPI) between the management controller and the BIOS chip, so that the processor runs the BIOS to modify the first configuration parameter to turn on the VMD function.

Among them, IPMI is an open standard for managing and monitoring platform management interfaces of server hardware. The BIOS may obtain some information of the BMC, such as system status, hardware configuration, sensor information, etc., through the IPMI. BT over eSPI is a setting of the BIOS in a computing device that can be used to start Bluetooth (BT) and communicate through a serial peripheral interface (SERIAL PERIPHERAL INTERFACE, eSPI) for connecting the BIOS chip to an external device.

Fig. 12 is a flowchart illustrating a VMD function closing process according to an embodiment of the present application. As shown in fig. 12, the method comprises the following steps:

S1201, in the case where the VMD function is in the on state, the management controller configures a second configuration parameter of the BIOS chip in response to the operation on the fourth control, and restarts the computing device.

The second configuration parameter is used for indicating that the VMD function is in a closed state.

S1202, updating the switch state of the VMD function in the fourth interface to be an off state.

For the above S1201-S1202, when the user needs to turn off the VMD function, the fourth control in the fourth interface is clicked. In response to this operation, the management controller performs the following: 1. the management controller sends a fourth instruction to the processor; 2. the processor responds to a fourth instruction, and runs the BIOS to acquire a first configuration parameter from the management controller; 3. the processor runs the BIOS and modifies the target option of the BIOS chip as a first configuration parameter; the target option is the switch state of the VMD function. After the modification is completed, the processor informs the management controller, which controls the computing device to restart to validate the second configuration parameters. After the management controller confirms that the validation is completed (the management controller reads new BIOS parameters after restarting to confirm whether the validation is completed), the VMD function is updated to be in a closed state on a fourth interface, and the user is indicated that the current computing device does not support violent hot plug.

The process of obtaining and modifying the second configuration parameter may refer to the description corresponding to fig. 11, and the description is not repeated again.

As previously described, VMD function shutdown requires reconfiguration of kernel parameters to ensure proper operation of the hard disk. Fig. 13 is a flowchart illustrating a process for configuring kernel parameters according to an embodiment of the present application. As shown in fig. 13, the technical solution of the embodiment of the present application may be configured by the following steps:

S1301, the management controller configures kernel parameters of an operating system operated by the processor.

The kernel parameter is used for supporting the hard disk to normally run on the operating system.

S1302, restarting the computing device.

For the above S1301-S1302, the management controller may execute the following: 1. the management controller sends a fifth instruction to the processor. 2. The processor executes a preset script to configure kernel parameters of the operating system in response to the fifth instruction. Wherein the preset script may be stored in a target location of the memory. The kernel parameters may include a high performance transmission mode to enable the PCIe device, a performance optimization mode to enable the PCIe bus, and so on. The management controller may issue instructions to the processor to cause the processor to run the operating system to complete the modification of the kernel parameters and then restart the computing device to validate the modified content.

As an example, the preset script may include the steps of: 1. the "/etc/default/grub" file is opened. 2. Entering edit mode, find "grub_ CMDLINE _linux=" crashkernel =auto. Lvm.lv= rhel/rootrd. Lvm.lv= rhel/swap rhgb quiet ", and enter pciehp.pciehp_force=1pci= pcie _bus_perf later (there is a space between the added content and the above, and no line feed). 3. The modification is saved. 4. Executing the command validates the modification, the validation command in different modes being as follows:

legacy mode: grub2-mkconfig-o/boot/grub2/grub.cfg;

UEFI mode: grub2-mkconfig-o/boot/EFI/EFI/redhat/grub. Cfg;

5. After the modification is completed, the computing device is restarted.

It should be appreciated that restarting a computing device, as referred to herein, is one way to indicate a restart after a processor modification is completed, and to confirm that the modification is completed by reading the kernel parameters after the restart is completed, and to inform the management controller. Or the processor informs the management controller after the modification is completed, the management controller instructs the restart, and after the restart is completed, the management controller confirms whether the kernel parameter is effective or not by re-reading the kernel parameter, and if the kernel parameter is not effective, the steps S1301-S1302 are re-executed. Embodiments of the present application are not limited to this specific implementation.

Fig. 14 is a management flowchart provided in an embodiment of the present application, and is described in detail with reference to fig. 14. Firstly, 1, the management controller reads the switch state of the VMD, and 2, judges whether the VMD needs to be started or not. If the starting is needed (corresponding to the user clicking the third control), starting the VMD function of the computing device configuration BIOS. 4. The management controller controls the computing device to restart. 5. And judging whether the VMD is started, if so, prompting violent hot plug and ending. If not, the step 3 is re-executed.

And if the user does not need to start the VMD (corresponding to the user clicking the fourth control), the management controller configures kernel parameters of the operating system, and the management controller controls the computing equipment to restart. 9. And judging whether the kernel parameters are configured correctly (namely, whether the computing equipment detects that the high-performance transmission mode is started or not) and returning to the step 7 if the kernel parameters are not configured correctly. If so, a first interface is displayed 10 to indicate whether the hard disk is in place. When the user needs to unload the hard disk (corresponding to the user clicking the first control), the power-on and unloading driver is controlled by the management controller 11, and the computing device prompts that the unloading is completed and ends. When the user needs to install the hard disk (corresponding to the user clicking the second control), 13, prompting the user to access the hard disk, 14, prompting the hard disk to be in place and run normally after the hard disk is inserted, and ending.

The user can clearly determine the location of the hard disk to be offloaded through the interface display. Further users can select the slot position of the hard disk to be unloaded through interface operation. According to the slot position specified by the user, the management controller can execute related unloading operation on the hard disk on the slot position, so that the hard disk is unloaded. The interface visual operation mode does not need the user to issue commands step by step, so that the use threshold of the user can be reduced, the time of manual configuration can be reduced, and the hard disk plug efficiency is improved. In addition, by replacing manual configuration, the configuration accuracy can be ensured, and the occurrence of configuration errors can be reduced.

Further, through interface operation, the complicated switching of VMD functional states is replaced, the convenience of operation is further improved, and various requirements of users are met.
