It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The method for controlling the hard disk state indicating device provided by the application can be applied to an application environment as shown in fig. 1, and comprises a RAID controller 102, a microcontroller 104 and a hard disk state indicating device 106, wherein the RAID (Redundant Arrays of Independent Drives, disk array) controller 102 is a hardware device or a software program for managing a hard disk drive or a solid state hard disk in a computer or a storage array, and the microcontroller 104 is a single-chip microcomputer integrating a main part of the microcomputer on a chip. The RAID controller 102 serves as a master device, and sends SGPIO signals carrying hard disk information to the microcontroller 104 through SGPIO protocol, where the SGPIO signals include a SClock signal, a SLoad signal, and a sdata out signal; when the microcontroller 104 detects that the falling edge of the SClock signal triggers an interrupt and the SLoad signal is at a low level, SDataOut signals are collected; analyzing the SDataOut signal to obtain a hard disk state signal; according to the hard disk status signal, a hard disk status indication signal is output to the hard disk status indication device 106 to be controlled. The microcontroller 104 may include an ARM (Advanced RISC Machine, advanced reduced instruction set machine) microcontroller, a CPLD microcontroller, an FPGA (Field-Programmable Gate Array, field programmable gate array) microcontroller, etc., and the hard disk status indicator 106 may be a device that reflects an operation status of the hard disk, and may include an LED (Light Emitting Diode ) lamp, an LED display screen, a voice player, etc. For the sake of more clear explanation of the present application, the RAID controller 102 will be exemplified by a RAID card chip, the microcontroller 104 is exemplified by an ARM microcontroller, and the hard disk status indicating device 106 is exemplified by an LED lamp.
In one embodiment, as shown in fig. 2, a method for controlling a hard disk status indication device is provided, and the method is applied to an ARM microcontroller for illustration, and includes the following steps:
in step S200, an SGPIO signal is received, where the SGPIO signal includes a SClock signal, a SLoad signal, and a SDataOut signal.
The RAID controller is configured to indicate the state of the hard disk in three manners, i.e., GPIO, SGPIO and I2C, where SGPIO is the most commonly used manner among the three manners, and the SGPIO signal is a signal output by the RAID card chip through the SGPIO bus, as shown in fig. 3, the SGPIO bus is divided into four pieces, i.e., SClock, SLoad, SDataOut and sdaatain, and its corresponding output signals are four signals, i.e., a SClock signal, a SLoad signal, a sdaataout signal and a sdaatain signal, where the SClock signal is a clock signal output by the RAID card chip; the SLoad signal is the last clock mark signal of the bit stream string, and the clock immediately following the last clock mark signal is the beginning of a new bit stream string signal; the SDataOut signal is a serial data output bit stream signal; the sdaatain signal is a serial data input bitstream signal. In this embodiment, the ARM microcontroller is explained by using M051 series of microcontrollers M054, numicro TM M051 series is as follows-M0 is a 32-bit microcontroller of the kernel, applied in the field of industrial control and requiring rich communication interfaces. NuMicro TM M051 series including M052xBN/xDN/xDE, M054xBN/xDN/xDE, M058xBN/xDN/xDE and M0516xBN/xDN/xDE SGPIO (serial Universal input output) are one method of serializing a general IO signal. SGPIO defines the communication of an initiating device (e.g., host bus adapter) and a target device (e.g., backplane of a pluggable hard drive). The target device converts the output signal to a number of parallel hard disk state signals and provides an input signal to the universal input signal line. The initiating and target devices may be comprised of one or more chips. If multiple chips are used, the signals driving the bus should be sorted to meet this criterion. Specifically, the microcontroller M054 passively receives the SGPIO signal sent by the RAID card chip through the SGPIO protocol.
In step S400, when the falling edge of the SClock signal triggers an interrupt and the SLoad signal is at a low level, the SDataOut signal is collected.
In the present embodiment, in the digital clock circuit, the instant at which the digital level changes from the high level (digital "1") to the low level (digital "0") is called a falling edge. The interruption refers to that when some unexpected situations occur and the host intervention is needed, the machine can automatically stop the running program and transfer to the program for processing the new situation, and the program which is suspended originally is returned to continue running after the processing is finished. The falling edge interruption is generated when the target signal changes from high level to low level. In this embodiment, after receiving the SGPIO signal, the microcontroller M054 initializes four signals of the SClock signal, the SLoad signal, the SDataout signal, and the SDatain signal in the SGPIO signal, initializes the SClock signal and the SLoad to be a falling edge interrupt, initializes the time period of the timer to be 64ms, configures the flicker frequency of the hard disk state indicating device, and when the SClock signal is a falling edge trigger interrupt, responds to the interrupt, and collects the SDataout signal. Specifically, the start of SGPIO signal transmission is not the start of each frame signal, but the SGPIO signal starts transmission. When the SGPIO signal does not work, the SClock, the SLoad and the SDataout are all at high level, when the SGPIO signal starts to work, the level of the SClock signal is pulled down (the falling edge is interrupted), which indicates that the SGPIO signal starts to transmit, the SLoad signal is synchronously pulled down, and the level of the SDataout signal changes when the rising edge is caused, so that at the moment, the SDataout is at high level, and the SDataout level signal sampled by the falling edge (interruption) of the next SClock signal is the first frame data. End of SGPIO signal transmission, which is not the end of each frame signal, but the SGPIO signal ends transmission. In the process of SGPIO signal transmission, when the SClock signal is detected to have no level change (continuously high level) in 64ms, the SGPIO signal transmission is considered to be ended, and all hard disk state indicating devices are closed. The end and start of each frame of the SGPIO signal, after the SGPIO signal starts to transmit, will send data in a frame-by-frame manner, and according to the SGPIO protocol, there are at least 5 low levels on the SLoad line in succession, and then there are high levels, indicating the end of this frame of data and the start of the next frame of data (the SDataOut signal detected by the next SClock falling edge is another frame of data). It will be appreciated that in this embodiment, the time period may be set to different values according to the specific circumstances.
Step S600, analyzing the SDataOut signal to obtain the hard disk state signal.
The SDataOut signal line carries hard disk running state information, and the microcontroller M054 parses the information according to the falling edge interrupt. Each frame of the SDataOut signal carries a plurality of drivers, each driver has three bits, bit0 is an Activity signal disc and has data interaction), bit1 is a State signal (hard disk insertion), and bit2 is Error signal disc Error. One driver manages one hard disk and a group of SGPIOs manages 4 hard disks, so the first 4 drivers (driver 0-driver 3) on the SDataOut signal are used. The correspondence is as follows:
activity signal State signal Error signal
Hard disk 0 Driver0.bit0 Driver0.bit1 Driver0.bit2
Hard disk 1 Driver1.bit0 Driver1.bit1 Driver1.bit2
Hard disk 2 Driver2.bit0 Driver2.bit1 Driver2.bit2
Hard disk 3 Driver3.bit0 Driver3.bit1 Driver3.bit2
After the microcontroller M054 collects the SDataOut signal, the SDataOut signal is analyzed according to the falling edge interruption, bit information carried by the SDataOut signal is read, and a hard disk state signal is obtained.
Step S800, according to the hard disk state signal, outputting a hard disk state indication signal to the hard disk state indication device to be controlled.
The hard disk state signal is a signal representing the operation state of the hard disk, and the operation state of the hard disk can include a read-write state, a hard disk in-place state, a hard disk error reporting state and the like, and the hard disk state indicating signal is used for controlling the to-be-controlled hard disk state indicating device to display the state of the hard disk.
In the method for controlling the hard disk state indicating device, an SGPIO signal is received, where the SGPIO signal includes an SClock signal, a SLoad signal, and an SDataOut signal; when the SClock signal falling edge triggers an interrupt and the SLoad signal is at a low level, SDataOut signals are collected; analyzing the SDataOut signal to obtain a hard disk state signal; and outputting a hard disk state indicating signal to the hard disk state indicating device to be controlled according to the hard disk state signal. The technical scheme can be completed by the ARM processor, and solves the problem that the ARM processor cannot analyze data and control the state of the hard disk at the same time, so that the ARM processor reduces cost and power consumption on the premise of realizing a good control effect.

Specifically, when the microcontroller M054 analyzes the hard disk status signals sent by the RAID card chip, different hard disk status indication signals are output to the hard disk indicator light to be controlled according to the different hard disk status signals. The hard disk status indication signal may include a hard disk in-place indication signal, a hard disk read-write indication signal, and a hard disk failure indication signal. The number of the hard disk indicator lamps can be one or more, and in this embodiment, a plurality of hard disk indicator lamps are adopted, including hard disk in-place indicator lamps, hard disk read-write indicator lamps and hard disk fault indicator lamps. When the hard disk state signal is a Locate signal, outputting a hard disk on-site indication signal to a hard disk on-site indication lamp to be controlled, and executing red flashing when the hard disk on-site indication lamp receives the hard disk on-site indication signal, wherein people can judge that the hard disk is in a selected state according to the flashing state of the red lamp; when the hard disk state signal is an Activity signal, outputting a hard disk read-write indicating signal to a hard disk read-write indicating lamp to be controlled, and executing green flashing when the hard disk read-write indicating lamp receives the hard disk read-write indicating signal, wherein people can judge that the hard disk has data interaction in a read-write state according to the state that the hard disk read-write indicating lamp is green flashing; when the hard disk state signal is an Error signal, a hard disk fault indication signal is output to a hard disk fault indication lamp to be controlled, and when the hard disk fault indication lamp receives the hard disk fault indication signal, red flashing is executed, and people can judge that the hard disk breaks down according to the red flashing state of the hard disk fault indication lamp. Therefore, the detection of the running state of the hard disk is not needed, the state of the hard disk indicator lamp is controlled through the hard disk state information fed back by the RAID card chip, so that a person can judge the current running state of the corresponding hard disk through the state of the hard disk indicator lamp, and the time and labor cost are saved.

The method is also compatible with providing the functions of an in-place indicator light and a read-write indicator light for the SAS/SATA hard disk only when the RAID controller is not available. In this embodiment, the hard disk state indicating device is an LED lamp, and the device connected with the ARM microcontroller may be SAS or SATA interface device, and may be directly connected with 8-12 hard disks at most; the device and the ARM microcontroller are directly connected through the SAS1_STATE-, the LED_SAS1_ACT1 and the ARM microcontroller, the STATE information of the device can be directly fed back to the ARM microcontroller, the ARM microcontroller and the LED lamp are connected with the ARM microcontroller through the GPIO, 8 groups are formed, and each group comprises LED_State and LED_active signals. The ARM controller can control the LED through the GPIO according to the information fed back by the Device, and feeds back corresponding information to a user. Specifically, SAS 1_state-is a hard disk detection signal, led_sas1_act1 is a hard disk read/write signal, when a hard disk is inserted, the ARM microcontroller hard disk detection signal is in a low level STATE, and when the hard disk has read/write activity, the ARM microcontroller detects that the hard disk read/write signal is in a low level STATE. After the ARM controller receives the signals and carries out logic judgment, the ARM controller outputs a hard disk state indication signal to the LED lamp to be controlled through the GPIO to realize the function of indicating the state of the hard disk. In this embodiment, when there is no RAID controller, the functions of the bit indicator light and the read/write indicator light are provided for only SAS/SATA hard disk, so as to realize functional diversification of ARM microcontrollers.
