For the sake of better clarity of explanation, the RAID controller 102 will be described with a RAID card chip, the microcontroller 104 is an ARM microcontroller, and the hard disk status indication device 106 is described with an LED lamp.
In one embodiment, as shown in fig. 2, a method for controlling a hard disk status indicator is provided, which is described by taking an example of applying the method to an ARM microcontroller, and includes the following steps:
step S200, receiving an SGPIO signal, wherein the SGPIO signal comprises an SClock signal, an SLoad signal and an SDataOut signal.
The RAID controller is used for indicating the state of the hard disk in three ways, namely, GPIO, SGPIO and I2C, the SGPIO is the most common way of the three, an SGPIO signal is a signal output by the RAID card chip through an SGPIO bus, as shown in fig. 3, the SGPIO bus is divided into four pieces, namely, SClock, SLoad, SDataOut and SDataIn, and corresponding output signals thereof are four signals, namely, an SClock signal, an SLoad signal, an SDataOut signal and an SDataIn, where the SClock signal is a clock signal output by the RAID card chip; the SLoad signal is a clock mark signal at the last of the bit stream string, and a clock immediately following the SLoad signal is the start of a new round of bit stream string signals; the SDataOut signal is a serial data output bit stream signal; the SDataIn signal is a serial data input bit stream signal. In this embodiment, the ARM microcontroller is explained by using a microcontroller M051 series M054, NuMicroTMM051 series is
M0 is a 32-bit microcontroller with a kernel, which is used in industrial control and in fields requiring rich communication interfaces. NuMicroTMThe M051 series including M052xBN/xDN/xDE, M054xBN/xDN/xDE, M058xBN/xDN/xDE and M0516xBN/xDN/xDE SGPIO (Serial Universal input output) is a method of serializing a general IO signal. SGPIO defines a boot device (e.g. aHost bus adapter) and a target device (e.g., a backplane that plugs into a hard drive). The target device converts the output signal to a plurality of parallel hard disk state signals and provides an input signal to the universal input signal line. The initiator and target devices may be comprised of one or more chips. If multiple chips are used, the signals driving the bus should be conditioned to meet this standard. Specifically, the microcontroller M054 passively receives an SGPIO signal sent by the RAID card chip through the SGPIO protocol.
In step S400, when the SClock signal falls to trigger an interrupt and the SLoad signal is at a low level, an SDataOut signal is collected.
In this 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 means that when some unexpected situations occur in the running process of the computer and the host needs to intervene, the machine can automatically stop the running program and transfer to the program for processing the new situation, and after the processing is finished, the original suspended program is returned to continue running. The falling edge interrupt 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, namely, an SClock signal, a SLoad signal, an SDataOut signal, and an SDataIn signal, in the SGPIO signal, initializes the SClock signal and the SLoad signal as a falling edge interrupt, initializes a timer period of 64ms, configures a flash frequency of the hard disk state indicating device, and acquires the SDataOut signal in response to the interrupt when the SClock signal triggers the interrupt for the falling edge. Specifically, the start of the SGPIO signal transmission is not the start of each frame signal, but the SGPIO signal transmission is started. When the SGPIO signal does not work, the level of the SClock signal is pulled low (falling edge interruption), which indicates that the SGPIO signal starts to transmit, the level of the SLoad signal is pulled low synchronously, and the level of the SDataOut signal changes at the time of rising edge, so that the SDataOut signal is at high level, and the SDataOut level signal sampled at the falling edge (interruption) of the next SClock signal is the first frame data. The end of the SGPIO signal transmission, which is not the end of each frame signal, but the SGPIO signal ends the transmission. During the process of transmitting the SGPIO signal, when the SClock signal is detected to have no change in level (continuously at a high level) within 64ms, the SGPIO signal is considered to be transmitted to be finished, and all hard disk state indicating devices are turned off. The end and start of each frame of the SGPIO signal, after the SGPIO signal starts to transmit, data is transmitted in a frame-by-frame manner, and according to the SGPIO protocol, there are at least 5 low levels and then high levels consecutively on the SLoad line, indicating the end of the frame data and the start of the data of the next frame (the SDataOut signal detected at the next SClock falling edge is another frame data). It is understood that, in the present embodiment, the time period may be set to different values according to specific situations.
Step S600, the SDataOut signal is analyzed, and a hard disk state signal is obtained.
The SDataOut signal line carries the hard disk running state information, and the microcontroller M054 parses the information according to the falling edge interrupt. Each frame of the SDataOut signal is provided with a plurality of drivers, each driver is provided with three bits, bit0 indicates that an Activity signal panel has data interaction, bit1 indicates a State signal (hard disk insertion), and bit2 indicates that an Error signal panel has errors. One driver manages one hard disk and a group of SGPIOs manages 4 hard disks, so the first 4 drivers on the SDataOut signal (driver0-driver3) are used. The corresponding relationship is as follows:
| activity signals | 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 acquires the SDataOut signal, the SDataOut signal is analyzed according to the falling edge interrupt, and the bit information carried by the SDataOut signal is read to acquire the hard disk state signal.
Step S800, according to the hard disk state signal, outputting a hard disk state indicating signal to a hard disk state indicating device to be controlled.
The hard disk state indicating signal is used for controlling the hard disk state indicating device to be controlled to display the hard disk state.
In the control method of the hard disk state indicating device, an SGPIO signal is received, wherein the SGPIO signal comprises an SClock signal, an SLoad signal and an SDataOut signal; when the SClock signal falling edge triggers interruption and the SLoad signal is at a low level, acquiring an SDataOut signal; 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 the problem that the ARM processor cannot analyze data and simultaneously control the state of the hard disk is solved, so that the cost and the power consumption are reduced on the premise of realizing a good control effect by the ARM processor.

Specifically, when the microcontroller M054 analyzes the hard disk state signal sent by the RAID card chip, different hard disk state indication signals are output to the hard disk indicator lamp to be controlled according to different hard disk state signals. The hard disk state indication signal may include a hard disk on-site indication signal, a hard disk read-write indication signal, and a hard disk fault indication signal. The hard disk indicating lamps can be one or multiple, and in the embodiment, a plurality of hard disk indicating lamps are adopted, including a hard disk on-site indicating lamp, a hard disk reading and writing indicating lamp and a hard disk fault indicating lamp.

Therefore, the running state of the hard disk does not need to be manually detected, the state of the hard disk indicator light is controlled through the hard disk state information fed back by the RAID card chip, a user can judge the corresponding current running state of the hard disk through the state of the hard disk indicator light, and time and labor cost are saved.
In one embodiment, the method further comprises receiving a hard disk detection signal and a hard disk read-write signal; and responding to the hard disk detection signal and the hard disk read-write signal, and outputting a hard disk state indicating signal to the hard disk state indicating device to be controlled through the GPIO.

In this embodiment, the hard disk status indicator is an LED lamp, and the device connected to the ARM microcontroller may be a SAS or SATA interface device, and may be directly connected to 8 to 12 hard disks at most; the equipment and the ARM microcontroller are directly connected with the ARM microcontroller through the SAS1_ STATE and the LED _ SAS1_ ACT1, STATE information of the equipment can be directly fed back to the ARM microcontroller, the ARM microcontroller and the LED lamp are connected with the ARM microcontroller through GPIO, the number of the ARM microcontroller and the LED lamp is 8, and each group of the ARM microcontroller comprises LED _ State and LED _ Active signals.
