The method for determining the operating state of the hard disk includes receiving an original signal of the operating state of the hard disk from a serial universal input and output port, determining whether the original signal of the operating state indicates normal or abnormal operation, and determining whether the operating state original signal indicates an abnormal operation is receiving operation Status original signal The previous operating status of the hard disk received before. The original signal indicates normal or abnormal operation. The original signal of the current operating status indicates normal operation based on the original signal of the hard disk's operating status and the serial universal input/output port.

The above description of the disclosure and the following description of the implementation manners are used to demonstrate and explain the spirit and principle of the present invention, and to provide a further explanation of the patent application scope of the present invention.

The detailed features and advantages of the present invention will be described in detail in the following embodiments. The content is sufficient to enable anyone familiar with the relevant art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of patent application and the drawings. Anyone who is familiar with relevant skills can easily understand the purpose and advantages of the present invention. The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention by any viewpoint.

The method for determining the operating status of a hard disk provided by one or more embodiments of the present invention is used to determine the operating status of an electronic device including a serial universal input and output port and a hard disk, especially the actual operating status of the hard disk. Please refer to FIG. 1. FIG. 1 is a functional block diagram of an operating system applicable to the method for determining the operating state of a hard disk in one or more embodiments of the present invention. The operating environment may include an electronic device 1, a processor 2, and a substrate. Baseboard management controller (BMC) 3. The electronic device 1 includes a hard disk 11 and a serial general purpose input/output (Serial general purpose input/output, SGPIO) port 13. The hard disk 11 is, for example, a serial ATA hard disk (SATA HDD) or a serial-connected SCSI hard disk. (SAS HDD), etc., are electrically connected to the serial universal input/output port 13. FIG. 1 exemplarily shows that the electronic device 1 includes a hard disk 11. In another embodiment, the electronic device 1 may also include a plurality of hard disks 11 electrically connected to the serial universal input and output ports 13. For example, the electronic device 1 can be a host bus adapter (HBA), a fault-tolerant array of independent disks (RAID), a platform controller hub (PCH), or Other devices that use serial general-purpose input and output to capture the status of the hard disk.

The processor 2 is, for example, a complex programmable logic device (CPLD), a field programmable gate array (FPGA), etc., and can be electrically connected to a serial universal input and output port 13. In this way, information about one or more hard disks 11 can be obtained. The processor 2 may include a register (such as a custom register) to temporarily store the acquired information of each hard disk 11. In one embodiment, the processor 2 is a complex programmable logic device arranged on a backplane (BP). The baseboard management controller 3 can be electrically connected to the processor 2 to read the information of each hard disk 11 of the electronic device 1 from the register to obtain the status of each hard disk 11, such as activity and presence ( locate) and abnormal (fail) status.

Please refer to FIG. 1 and FIG. 2 together. FIG. 2 is a flowchart of a method for determining the operating state of a hard disk according to an embodiment of the present invention.

In step S101, the processor 2 receives an original signal of the operating state of the hard disk 11 from the serial universal input/output port 13, where the original signal of the operating state may include the activity state signal of the hard disk 11, and the location (locate). ) Status signal and abnormal (fail) status signal. As mentioned above, in the operating system shown in Figure 1, since the processor 2 obtains the information of the hard disk 11 through the serial universal input and output port 13 instead of directly from the hard disk 11, the information obtained may be affected by The serial universal input/output port 13 is unstable and incorrect. The original signal of the operating state of the hard disk 11 obtained from the serial universal input/output port 13 in step S101 does not necessarily represent the actual operating state of the hard disk 11. Therefore, the processor 2 will perform the following steps again.

In step S102, the processor 2 determines whether it has received the original signal of the previous operating state of the hard disk 11 before receiving the original signal of the operating state. Furthermore, when the electronic device 1 just starts to operate (turn on), an unstable situation often occurs. Step S102 can be used to determine whether the electronic device 1 is just turned on. When the processor 2 determines that it has not received the original operating state signal of the hard disk 11 before receiving the original operating state signal, that is, when it determines that the electronic device 1 has just been turned on, step S103 is executed. In addition, the start-up phase of the electronic device 1 can also be defined as an operation period after the electronic device 1 receives power and is turned on. In this embodiment, the processor 2 determines whether the original signal of the previous operating state of the hard disk 11 has been received before an operating period before the original signal of the operating state is received. For example, the operation cycle may be the first and second cycles of the load signal (SLoad signal) of the serial universal input/output port 13. Among them, the load signal is used to indicate when the bit stream ends and when it restarts.

In step S103, the processor 2 generates an operating status correction signal based on the original operating status signal of the hard disk 11 and the enabling status signal of the serial universal input/output port 13. Among them, the enabling state signal can indicate that the serial universal input and output port 13 is in the enabled or disabled state. Furthermore, the processor 2 can select the abnormal state signal in the original operating state signal of the hard disk 11 to perform operation with the enable state signal of the serial universal input and output port 13 to generate the operating state correction signal. Assuming that the abnormal state signal in the original signal of the operating state is defined as sgpio_fail (the value is 0 when the normal state is indicated; the value is 1 when the abnormal state is indicated), and the enabled state signal is defined as sgpio_active_n (the value is when the disabled state is indicated 0; when the enabled state is indicated, the value is 1), the processor 2 will use the following arithmetic logic to generate the operating state correction signal hdd_fail (the value is 0 when the normal state is indicated; the value is 1 when the abnormal state is indicated) :

hdd_fail=sgpio_fail&(!sgpio_active_n), that is, perform the inverse operation on the enable state signal, and perform the AND operation on the result of the inverse operation and the abnormal state signal to generate the operating state correction signal.

In step S104, the processor 2 executes a delay procedure on the operating state correction signal according to a preset time to generate and output the operating state determination signal. Among them, the delay procedure is, for example, a de-bounce function. Assuming that the preset time is t seconds, the processor 2 will wait for t seconds in this step and then use the generated operating state correction signal as an operating state determination signal to store in the register or output to the baseboard management controller 3 . Further, the preset time may depend on the reading period of the baseboard management controller 3. Furthermore, the preset time may be between 2 to 5 times the reading period, and 4 times is Better. In one embodiment, the baseboard management controller 3 receives the operation status determination signal from the processor 2 and generates and outputs corresponding operation status information accordingly.

In the embodiment shown in FIG. 2, when the determination result of the processor 2 in step S102 is that it has received the original signal of the previous operating state of the hard disk 11 before receiving the original signal of the operating state, the processor 2 will determine the electronic device 1 It is not in the initial startup stage, so the original signal of the operating state can be directly stored or output. In the embodiment defined as the first operation period after the electronic device 1 receives power and is turned on in the just booting stage, the processor 2 has received the previous operation of the hard disk 11 before determining the operation period before receiving the original signal of the operation state. When the original signal is in the state, it is determined that the electronic device 1 is not in the just-starting stage, and the original signal in the operating state is directly stored or output.

In one embodiment, the method for determining the operating state of the hard disk may further include using the processor 2 (especially a complex programmable logic device) to analyze the original operating state signal obtained before the above step S103 is executed. Furthermore, the active state signal, the presence state signal, and the abnormal state signal in the original operating state signal provided by the serial universal input and output port 13 are serial signals. Therefore, the processor 2 can first connect the serial form of the active state signal, the presence state signal, and the abnormal state signal. The original signal of the operating state is decoded and converted into parallel active state signals, in-position state signals, and abnormal state signals to capture the abnormal state signals to execute the signal processing procedure of step S103 described above.

Through the above steps, the processor 2 can perform special judgment and signal processing procedures on the signal received from the serial universal input and output port 13, so as to avoid the unstable state of the electronic device 1 when it is turned on, thereby improving the hard disk The accuracy of the operation status determination.

The method for determining the operating status of the hard disk of the present invention can be applied to the boot phase of an electronic device including a hard disk and a serial universal input/output port as described above, as well as other operating phases. Please refer to FIG. 1 and FIG. 3 together, in which FIG. 3 is a flowchart of a method for determining the operating state of a hard disk according to another embodiment of the present invention.

In step S201, the same as step S101, the processor 2 receives the original signal of the operating state of the hard disk 11 from the serial universal input and output port 13, where the original signal of the operating state may include the active state signal of the hard disk 11, the presence signal Status signal and abnormal status signal.

In step S202, the processor 2 determines whether the original operating state signal indicates normal operation. Furthermore, this step may include using the processor 2 (especially a complex programmable logic device) to analyze the original signal of the operating state obtained. In detail, the active state signal, the presence state signal and the abnormal state signal of the original operating state signal provided by the serial universal input and output port 13 are serial signals, so the processor 2 can first connect the serial form The original signal of the operating state is decoded and converted into parallel active state signals, in-position state signals and abnormal state signals, and the abnormal state signals are captured to determine whether they indicate normal operation. For example, when the value of the abnormal state signal is 0, it indicates normal operation; and when the value of the abnormal state signal is 1, it indicates abnormal operation. When the processor 2 determines that the original signal of the operating state is not indicative of normal operation but abnormal, step S203 is executed.

In step S203, the processor 2 determines whether the previous operating state original signal of the hard disk received before receiving the operating state original signal indicates that the operation is normal. When the processor 2 determines that the original signal of the previous operation state indicates that the operation is normal, steps S204 and S205 are executed. In step S204, the processor 2 generates an operating status correction signal based on the original operating status signal of the hard disk 11 and the enabling status signal of the serial universal input/output port 13. In step S205, the processor 2 executes a delay procedure on the operating state correction signal according to a preset time to generate and output an operating state determination signal. Among them, the detailed implementation content of steps S204 and S205 are similar to the implementation content of the aforementioned steps S103 and 104, and therefore will not be repeated here. In one embodiment, the baseboard management controller 3 receives the operation status determination signal from the processor 2 and generates and outputs corresponding operation status information accordingly.

In the embodiment shown in FIG. 3, when the determination result of the processor 2 in step S202 is that the original signal of the operation state indicates that the operation is normal, or the determination result of step S203 is that the original signal of the previous operation state indicates that the operation is abnormal, processing is performed The device 2 will determine that the electronic device 1 is not in an unstable state, so it can directly store or output the original signal of the operating state.

When the processor 2 judges that the state of the hard disk 11 changes from normal to abnormal, because the processor 2 obtains the information of the hard disk 11 through the serial universal input and output port 13 instead of directly from the hard disk 11, the change from normal to abnormal The abnormal situation may be caused by the instability of the serial universal input/output port 13 rather than the actual condition of the hard disk 11. Therefore, through the above steps, the processor 2 can perform special judgment and signal processing procedures on the signal received from the serial universal input and output port 13, thereby improving the accuracy of determining the operating state of the hard disk and reducing the occurrence of false alarms. .

The embodiment of FIG. 2 described above is used for signal processing when the electronic device 1 is just turned on; the embodiment of FIG. 3 is used for signal processing when the operating signal output by the electronic device 1 changes from normal to abnormal. In another embodiment, the method for determining the operating state of the hard disk will perform special signal processing when the electronic device 1 is just turned on and when the operating signal changes from normal to abnormal. Please refer to FIGS. 1 and 4 together. FIG. 4 is a flowchart of a method for determining the operating state of a hard disk according to another embodiment.

Steps S301 to S304 shown in FIG. 4 are the same as steps S101 to S104 shown in FIG. , Or the signal processing performed during an operation period after the power is received), the details of which are as described in the previous embodiment, and will not be repeated here. When the processor 2 determines that the electronic device 1 is not in the just-turned-on state, it will perform step S305: determining whether the original signal of the operating state indicates that it is operating normally. When the processor 2 determines that the original operating state signal is not indicative of normal operation but is abnormal, it performs step S306: determining whether the previous operating state original signal of the hard disk received before receiving the original operating state signal indicates normal operation. When the processor 2 determines that the original signal of the previous operating state indicates that the operation is normal, which means that the processor 2 determines that the original signal of the operating state changes from normal to abnormal, it will execute the signal processing procedures of steps S303 and S304. Among them, steps S305 and S306 are respectively the same as steps S202 and S203 shown in FIG. 3, and the details are not repeated here.

In the embodiment shown in FIG. 4, when the determination result of the processor 2 in step S305 is that the original signal of the operating state indicates that the operation is normal, or the determination result of step S306 is that the original signal of the previous operation state indicates that the operation is abnormal, processing is performed The device 2 will determine that the electronic device 1 is not in a state of signal change, so it can directly store or output the original signal of the operating state.

With the above content, the method for determining the operating state of the hard disk disclosed in this case can determine whether the applied electronic device is in an unstable state to selectively execute a special operating state signal processing program, thereby improving the accuracy of determining the operating state of the hard disk To reduce the occurrence of false alarms.
