Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The hard disk control method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. In one embodiment, a computer device is provided, which may be a server, the internal structure of which may be as shown in fig. 1. The computer device includes a processor, a memory, and a network interface connected by a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program, and a database. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The database of the computer device is used for storing hard disk control data. The network interface of the computer device is used for communicating with an external terminal through a network connection. The computer program is executed by a processor to implement a hard disk control method.
Those skilled in the art will appreciate that the architecture shown in fig. 1 is merely a block diagram of some of the structures associated with the disclosed aspects and is not intended to limit the computing devices to which the disclosed aspects apply, as particular computing devices may include more or less components than those shown, or may combine certain components, or have a different arrangement of components.
In an embodiment, as shown in fig. 2, a hard disk control method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
step 201, in the process of powering on the server, controlling other hard disks in the server except the hard disk where the operating system is located to be in a power-down state.
The hard disk where the operating system is located refers to a hard disk loaded with an operating system installation package or an operating system image file, that is, the operating system of the server can be started or installed by driving the hard disk. Generally, the number of hard disks in which the operating system is located is one. The hard disk in the server may include a plurality of them. In the actual operation process of the server, the plurality of hard disks can automatically trigger the power-on operation in the power-on process of the server, that is, the plurality of hard disks are in a parallel execution state in the power-on process of the server.
In this case, in order to avoid the problem of confusion of configuration disk identifiers caused by parallel execution, the server may preferentially ensure that the hard disk where the operating system is located is in a power-on state, so as to normally start the operating system of the server, control other hard disks except the hard disk where the operating system is located to be in a power-off state, and in the process of starting the operating system, the initialization of the hard disk where the operating system is located is not affected.
Alternatively, the server may disconnect the high-speed serial computer expansion bus standard PCI-E link of each of the other hard disks by controlling the disconnection of the PCI-E link, so that each of the other hard disks is in a power-down state.
In this embodiment, the server may execute a PCI-E Link disconnection operation on a controller where the other hard disk is located through a Basic Input Output System (BISO), so that the other hard disk is in a power-Down state.
Optionally, the server may further set the value of the register of each of the other hard disks to a second value, so that each of the other hard disks is in a power-down state.
In this embodiment, the server may also control the states of the other hard disks by modifying the values of the registers corresponding to the other hard disks, for example, modifying the values of the registers corresponding to the other hard disks to a second value, where the second value may be "1" or "0", so as to control the other hard disks to be in a power-down state.
Step 202, after the operating system is started, a drive letter is configured for the hard disk where the operating system is located.
In this embodiment, after the server is powered on, it is detected that the hard disk where the operating system is located is in a powered-on state, the hard disk where the operating system is located is driven to run, and the operating system in the hard disk is started. After entering the operating system, the server performs initialization processing on the hard disk where the operating system is located, and configures a corresponding drive letter for the hard disk where the operating system is located, for example, the drive letter may be a preset C drive, which is not limited in this embodiment.
And step 203, controlling other hard disks to sequentially enter a power-on state, and configuring corresponding disk identifiers for the other hard disks.
In this case, the server needs to control each of the other hard disks to sequentially enter a power-on state to perform hard disk initialization processing on each of the other hard disks, and configure corresponding disk identifiers for the other hard disks.
In this embodiment, since the hard disk is in the firmware with the non-hot-plug function, after the server enters the operating system, the server cannot acquire the actual power-on state of the other hard disks. Based on this practical situation, after the server enters the operating system, the state of each of the other hard disks needs to be detected by the preset hot plug driver, and the controller drivers corresponding to the other hard disks are enabled, that is, the other hard disks are controlled to sequentially enter the power-on state by the preset hot plug driver, so that after the server enters the operating system, the power-on states of the other hard disks can still be detected, and corresponding disk identifiers are configured for the other hard disks.
In the hard disk control method, in the power-on process of the server, other hard disks except the hard disk where the operating system is located in the server are controlled to be in a power-off state, after the operating system is started, the hard disk where the operating system is located is configured with the disk identifier, the other hard disks are controlled to sequentially enter the power-on state, and the other hard disks are configured with the corresponding disk identifiers. In the embodiment, the server controls all the hard disks except the hard disk where the operating system is located to be in a power-down state in the starting process, after the server is started up and the operating system is started based on the hard disk where the operating system is located, only the hard disk where the operating system is located is in the power-on state, namely, only the hard disk where the operating system is located is configured with the disk identifier, the situation that the disk identifier configuration is disordered between the hard disk where the operating system is located and other hard disks due to the fact that the hard disk where the operating system is located and other hard disks are executed in parallel is avoided, and furthermore, after the operating system is started, the server controls other hard disks to sequentially enter a power-on state, and sequentially distributes disk identifiers for the other hard disks, so that the condition that the disk identifier configuration is disordered among the other hard disks due to the parallel execution of the other hard disks is avoided, and the problem that the hard disks float before different hard disks under Linux is effectively solved.
In order to avoid confusion of the disk signatures distributed at the same time, in an alternative embodiment, as shown in fig. 3, the server controls each of the other hard disks to sequentially enter the power-on state, and configures corresponding disk signatures for each of the other hard disks, including:
step 301, controlling other hard disks to sequentially enter a power-on state according to a preset hard disk control sequence.
The preset hard disk control sequence can be determined according to user requirements; the size of the hard disk space may also be determined, which is not limited in this embodiment.
Optionally, the server may control the high-speed serial computer expansion bus standard PEI-e link of each other hard disk to recover the connection, so that each other hard disk is in a powered-on state.
In this embodiment, the server may execute the PCI-E Link connection operation Link retry on the hard disk controllers of other hard disks except the hard disk where the operating system is located through the BISO, so that the other hard disks are in a powered-on state.
Optionally, the server may further set the value of the register of each of the other hard disks to the first value, so that each of the other hard disks is in a power-on state.
The server may also control the state of the other hard disks by modifying the values of the registers corresponding to the other hard disks except the hard disk where the operating system is located, for example, modifying the values of the registers corresponding to the other hard disks to a first value, where the first value may be "0" or "1", so as to control the other hard disks to be in a powered-on state.
In this embodiment, the server respectively controls, according to a preset hard disk control sequence and based on the hard disk identifier, each of the other hard disks except the hard disk where the operating system is located to sequentially enter a power-on state.
Step 302, calling a preset hot plug driver to detect the state of each other hard disk, sequentially performing hard disk initialization processing on the hard disk in the powered-on state, and configuring corresponding disk characters for the hard disk in the powered-on state.
In this embodiment, the computer device controls the hard disk to enter the power-on state, and a situation of hard disk power-on failure may also occur, so that the computer device needs to detect the states of the other hard disks controlled to execute the power-on operation, except for the hard disk where the operating system is located, again through the preset hot-plug driver, and determine the hard disk that is successfully in the power-on state from the hard disks, thereby performing initialization processing and disk identifier configuration processing on the hard disk that is already in the power-on state. For example, the hard disk control sequence is a hard disk B and a hard disk C, the server controls the hard disk B to be in a power-on state, meanwhile, the server calls a preset hot plug drive PEI-e Hotpug to detect whether a PEI-e device is in hot access or not, if so, the PEI-e Hotpug detects that the hard disk B is in hot access, the PEI-eHotpug enables the hard disk B to be driven by a controller, the server can acquire information of the hard disk B after the system is started, initialize the hard disk B and configure a corresponding disk identifier for the hard disk B; after configuring the corresponding disc symbol for the hard disc B, the server controls the hard disc C to be in a power-on state, meanwhile, the server calls a preset hot plug drive PEI-e Hotpug to detect whether the PEI-e device is in hot access or not, if so, the PEI-e Hotpug detects that the hard disc C is in hot access, the PEI-e Hotpug enables the controller drive where the hard disc C is located, the server can obtain the information of the hard disc C after the system is started, initialize the hard disc C and configure the corresponding disc symbol for the hard disc C. If there are multiple hard disks, the method for controlling power-on and configuring the disk identifier is similar, and this embodiment does not limit this.
In this embodiment, since the hard disk belongs to the non-hot plug firmware, the server may detect the state of the hard disk and enable the drive by using the PEI-e hot plug, so that after the server enters the operating system, the server may still perform initialization processing on the hard disk and configure corresponding disk identifiers for the hard disk, and the server is executed based on a preset hard disk control sequence, and under the condition that a plurality of other hard disks are not executed in parallel, the situation that the disk identifiers are configured for the hard disk is disordered is avoided.
In an optional embodiment, the method further includes that the server determines that the disk where the operating system is located is intended to drive the hard disk to start the operating system in a process of starting the server, where:
and determining the hard disk where the operating system is located according to the parameter information of all the hard disks in the server.
In this embodiment, the server obtains parameter information of each hard disk by detecting the in-place state of the hard disk, and determines the hard disk where the operating system is located and other hard disks. The parameter information of the hard disk includes a hard disk identifier, a hard disk space size, a hard disk address, information of a register corresponding to the hard disk, and the like, which is not limited in this embodiment.
In this embodiment, the server determines the hard disk where the operating system is located according to the parameter information of the hard disk, and in the subsequent hard disk control process, the system where the operating system is located is always kept in a normal power-on state, so that the operating system of the server can be ensured to be started normally.
To better explain the above method, as shown in fig. 4, this embodiment provides a hard disk control method, which specifically includes:
s101, determining a hard disk where an operating system is located according to parameter information of all hard disks in a server;
s102, in the process of powering on the server, controlling other hard disks except the hard disk where the operating system is located in the server to be in a power-down state;

and S105, calling the preset hot plug drive to detect the states of other hard disks, sequentially carrying out hard disk initialization processing on the hard disks in the powered-on state, and configuring corresponding disk symbols for the hard disks in the powered-on state.
In the embodiment, the server controls all the hard disks except the hard disk where the operating system is located to be in a power-down state in the starting process, after the server is started up and the operating system is started based on the hard disk where the operating system is located, only the hard disk where the operating system is located is in the power-on state, namely, only the hard disk where the operating system is located is configured with the disk identifier, the situation that the disk identifier configuration is disordered between the hard disk where the operating system is located and other hard disks due to the fact that the hard disk where the operating system is located and other hard disks are executed in parallel is avoided, and furthermore, after the operating system is started, the server controls other hard disks to sequentially enter a power-on state, and sequentially distributes disk identifiers for the other hard disks, so that the condition that the disk identifier configuration is disordered among the other hard disks due to the parallel execution of the other hard disks is avoided, and the problem that the hard disks float before different hard disks under Linux is effectively solved.
