Description

A system and method for displaying the status of the server's hard disk using a serial port {SYSTEM AND METHOD FOR DISPLAYING HARD DISK STATUS OF SERVER USING SERIAL PORT}

The present invention relates to a system and method for displaying hard disk status of a server using a serial port. In particular, a display device having a minimum hardware status of a server hard disk using Unix or Linux as an operating system (OS), and the display device. The present invention relates to a system and method for displaying a hard disk status of a server using a serial port, which is displayed using a processor included in the server and connected through a serial port.

In general, a RAID (Redundant Array of Independent Disks) system is a hardware device for securing data stability of a hard disk used as a main storage device in a server. Among them, taking RAID Level-1 as an example, it uses a technique called mirroring, and when two identical hard disks are installed and data is recorded, the same data is simultaneously recorded on two hard disks. Only one disk capacity is secured, but if an abnormality occurs in one hard disk, it informs the administrator and requests the replacement of the device. When a new hard disk device is replaced, the RAID system automatically copies the contents of the normal device to the new device so that the two devices are always in the same state. Since this method rarely breaks two devices at the same time, it can be a very safe system for data preservation if the administrator responds quickly.

In the RAID system, as shown in FIG. 1, LEDs are installed on each storage device to indicate whether the device is operating normally or not. For example, when an error occurs in storage device-1, the error indicator LED flashes so that the system administrator can be notified to take action, and depending on the system, an alarm sound is generated to inform the system more actively.

As an OS (Operation System) mainly used in various server systems including Internet servers, there are Unix and Linux, which have the same functions as derivatives thereof. These OSs have built-in soft-RAID, so you can use the RAID function without having a RAID system (hereinafter referred to as hardware RAID) composed of expensive hardware. However, since soft-RAID is operated by software, its speed is much lower than that of hardware RAID, so it is mainly used in small servers or simple servers.

Soft-RAID also has several levels depending on the internal function, but the explanation is based on the simplest RAID Level-1. Soft-RAID, like hardware RAID, installs two identical hard disks and manages them as one hard disk. When any data is recorded on the server, the same data is stored on each of the two hard disks by the OS's RAID management software. At this time, it takes twice as much time as compared to a single hard disk or hardware RAID system, but the same data stability as hardware RAID can be secured without additional cost.

Unlike hardware RAID, soft-RAID is implemented by software, so it cannot report errors using hardware such as LEDs, so it records the status of hard disk devices in a specific file (a file named mdstat) from time to time. You can check the status of the hard disk devices by browsing this file.

Soft-RAID is basically a system operated by software, so there are some limitations, the biggest of which is that it cannot quickly and easily notify the administrator when an abnormality occurs in the hard disk device. If an error occurs among the hard disks that make up the server system, the system administrator must recognize and take action as soon as possible to ensure data stability. In hardware RAID, when an error occurs, an alarm and a warning lamp indicating which hard disk has a problem Mark through the etc. In contrast, in the case of Soft-RAID, even if the OS detects that a problem has occurred in the hard disk and records it in the status report file, the administrator must access the server and check it to recognize it. Because there is no way to inform, it often happens that the timing of repairs is missed.

The procedure for the administrator to check the server system status is as follows.

1) Enter ID

Turn on the console device (monitor) of the server system and enter the system administrator ID. System management is generally configured to be impossible remotely for server security, so the administrator must move to the location where the server is located and input it from the console device installed on the server.

2) Enter password

Enter the system administrator's password to log-in. If the log-in status is always maintained, the 1) and 2) processes may be omitted. However, due to the security of the server, it is configured to automatically log-out after a period of time, so such a measure may become a security flaw.

3) Enter the confirmation command of the status report file

Move to the directory where the status report file is located and enter the confirmation command to confirm.

As described above, the status report file can be checked only after a minimum of 3 steps of input procedure, and the administrator can recognize which device is abnormal only when this file is decrypted. It is difficult to maintain stability at its best.

For this reason, although soft-RAID is a method that provides significant data stability, it is considered to be ineffective among actual system administrators and is not widely used.

The team that developed Soft-RAID also recognized these limitations and recently improved to send error reports to the administrator's e-mail to improve them. This method has to go through a complicated process such as installing a mail processing daemon on the server, monitoring the status of RAID devices, and installing another daemon that sends mail to the server, and these programs increase the load on the server. There is this.

However, although the installation process is complicated, this method was a very effective means of reporting errors to the administrator at the beginning of development, but recently, it disguises itself as such an error reporting email and transmits various hacking programs or ransomware. As the security of the security is weakened, even if a report e-mail is received, it is not viewed but ignored, so it is not getting a great effect.

2 is a detailed circuit diagram of a hard disk status display system of a server using a serial port according to an embodiment of the present invention, (a) is a detailed circuit diagram of the system, and (b) is a diagram showing an arrangement example of LEDs.

In the hard disk status display system of a server using a serial port according to an embodiment of the present invention, as shown in FIG. 2, the processor 100 and the serial port P of the processor 100 and the server S are connected to each other. It includes a display device 200 connected through.

The processor 100 is included in the server S and opens the status report file in which the status of the first and second hard disks are recorded in a read mode, and extracts the first and second hard disk operation status data in the status report file. Close the report file and open the serial port (P) of the server (S) to determine whether the serial port (P) is in use, and if it is not in use, the first and second hard disk operation status data are transferred to the serial port (P). It outputs to and closes the serial port (P).

The processor 100 is connected to the display device 200 through the serial port P of the server S and controls the on and off operations of the display device 200.

On the other hand, in the case of a server in which the serial port (P) is not installed, a module that outputs the serial port through USB can be used, so it is more flexible than the method using the parallel port.

The status report file in which the status of the hard disk is recorded, as illustrated in FIG. 3, is a specific file (a file named mdstat), and the status of the first and second hard disks is recorded.

The parts indicated by arrows ⓐ and ⓑ indicate the status of the first and second hard disks, respectively, and have the following meanings.

Ⓐ line

md0: Indicates that two hard disks (ie, the first and second hard disks) are bound together under the name md0. That is, when a user writes data to a virtual hard disk named md0, it is actually all recorded on each hard disk constituting md0.

active raid1 hdc1[0] hdd1[1]: two hard disks named hdc1 (first hard disk) (serial number [0]) and hdd1 (second hard disk) (serial number [1]) are raid1( RAID Level-1), which means it is in operation. If any of the two hard disks have a problem, the device name is removed from this list and displayed.

Ⓑ line

Number: 117218176

It represents the capacity of the hard disk in block units (a block is a unit in which data is recorded by being bundled with RAID).

[2/2]: Indicates that both the first and second hard disks are operating normally.

[UU]: This is the first and second hard disk operation status data. When both the first and second hard disks (hdc1, hdd1) are normal, [UU] is displayed, and the first and second hard disks (hdc1, hdd1) 1 When an error occurs in the hard disk (hdc1), [_U] is displayed, and when an error occurs in the second hard disk (hdd1), [U_] is displayed.

Of the various types of information above, the [UU] at the end of the ⓑ line is the most important. If it is marked under-bar, it can be confirmed that there is a problem with the corresponding device.

Here, the identification code D represents the hard disk operation state data, D1 represents the first data, and D2 represents the second data.

The display device 200 is connected to the processor 100 through the serial port (P) of the server (S) and reads the first and second hard disk operation status data from the processor 100 through a communication port to obtain LED display data. It is assembled and serves to display the operating states of the first and second hard disks based on the assembled LED display data.

As shown in FIG. 2, the display device 200 is connected to the server S through a wire through a connector 210.

As described above, since the display device 200 is configured as a separate device from the server S, installation and maintenance are very easy, and the location can be freely changed. In particular, if the display device 200 is disposed in front of the server S The hard disk status of the server S can be intuitively observed.

The display device 200 includes a connector 210, a converter 220, a buzzer 230, an initialization switch 240, a first hard disk normal display LED 260, a first hard disk abnormal display LED 260', A second hard disk normal display LED 270, a second hard disk abnormal display LED 270', a resistor R1, a resistor R2, and a microcontroller 250 are included.

The connector 210 is a connector that receives serial data (especially, first and second hard disk operation status data) from the serial port P of the server S, from the serial port via the USB port in the server S. It can also be supplied.

The connector 210 can be configured as, for example, an RS-232C connector.

The converter 220 serves to convert the voltage (eg, RS-232C voltage) of the serial port P into a voltage of a preset level (a voltage of a level required by the microcontroller).

The converter 220 converts, for example, a 12V voltage level signal received from the connector 210 into voltages of 0V and +5V.

The buzzer 230 plays a role of actively notifying an administrator by generating an alarm sound when an abnormality occurs in one or more of the first and second hard disks.

When the initialization switch 240 is turned on, it initializes the display device 200 and stops driving of the buzzer 230.

The initialization switch 240 is for initializing the hard disk status display system of the present invention before the administrator recognizes the abnormal situation and manages the server S. Since the hard disk status display system of the present invention is configured separately from the server (S), when the power of the server (S) is turned off in order to manage the server (S), the buzzer 230 receives a normal signal from the server (S). This is because the alarm keeps sounding until it arrives, so the administrator stops it.

When the first hard disk normal display LED 260 and the first hard disk abnormal display LED 260' are lit, each of the normal and abnormal states of the first hard disk is displayed.

The first hard disk normal display LED 260 and the first hard disk abnormality display LED 260' have different emission colors. That is, as illustrated in FIG. 2B, the first hard disk normal display LED 260 may use a green (G) LED, and the first hard disk abnormal display LED 260' uses a red (R) LED. I can.

When the second hard disk normal display LED 270 and the second hard disk abnormal display LED 270' are lit, each of the normal and abnormal states of the second hard disk is displayed.

The second hard disk normal display LED 270 and the second hard disk abnormality display LED 270' have different emission colors. That is, as illustrated in FIG. 2B, the second hard disk normal display LED 270 may use a green (G) LED, and the second hard disk abnormal display LED 270' uses a red (R) LED. I can.

One side of the resistor R1 is connected to the first hard disk normal display LED 260 and the first hard disk abnormal display LED 260', and the other side is grounded.

One side of the resistor R2 is connected to the second hard disk normal display LED 270 and the second hard disk abnormal display LED 270', and the other side is grounded.

The microcontroller 250 serves to control the entire display device 200 by receiving operation status data of the first and second hard disks through a communication port.

In more detail, the microcontroller 250 initializes the hardware when the driving power is applied, and when the initialization switch 240 is turned off, it reads the state of the communication port to determine whether the first and second hard disk operation state data are received. When it is determined and received, the first and second hard disk operation status data are read from the communication port to assemble the LED display data, and the assembled LED display data is transferred to the first hard disk normal display LED 260 and the first hard disk. The operation of these LEDs is controlled by outputting to the disk abnormality display LED 260', the second hard disk normal display LED 270, and the second hard disk abnormality display LED 270', and one of the first and second hard disks. When an abnormality occurs in the abnormality, the buzzer 230 is operated to generate an alarm sound.

When the initialization switch 240 is turned on, the microcontroller 250 initializes by turning on the first hard disk normal display LED 260 and the second hard disk normal display LED 270, and then turns off the buzzer 230. Debounce processing.

Meanwhile, in the above description, the first hard disk normal display LED 260 and the first hard disk abnormal display LED 260' are two LEDs that emit light in different colors, such as a green (G) LED and a red (R) LED. It was configured, but instead, it may be configured with one two-color LED that emits light in two colors.

Meanwhile, in the above description, the second hard disk normal display LED 270 and the second hard disk abnormality display LED 270' are two LEDs that emit light in different colors, such as a green (G) LED and a red (R) LED. It was configured, but instead, it may be configured with one two-color LED that emits light in two colors.

A method of displaying a hard disk status using a system for displaying a hard disk status of a server using a serial port according to an embodiment of the present invention configured as described above will be described.

4A, 4B, and 4C are flow charts for explaining a method of displaying a hard disk status using a hard disk status display system of a server using a serial port according to an embodiment of the present invention, and FIG. 5 is a report data assembly of FIG. As a detailed flow chart for step S130, where S stands for step.

First, the processor 100 opens a status report file for recording the status of the first and second hard disks in a read mode (S10), and searches the first and second hard disk operation status data in the status report file. Extract (S20).

Next, since the processor 100 has extracted all the necessary data, it closes the status report file (S30) and opens the serial port (P) of the server (S) (S40).

Subsequently, the processor 100 determines whether the serial port P is in use (S50).

If the serial port (P) is being used in the step (S50) (Y), this step (S50) is repeated.

On the other hand, if the serial port (P) is not in use (N), the processor 100 outputs the first and second hard disk operation status data to the serial port (P) (S60), and then connects the serial port (P). Close (S70).

Subsequently, when the driving power is applied, the microcontroller 250 initializes the hardware (S80) and determines whether the initialization switch 240 is turned on (S90).

When the initialization switch 240 is turned off (N) in the step S90, the microcontroller 250 reads the state of the communication port (S100), and whether the first and second hard disk operation status data are received. It is determined (S110).

If the first and second hard disk operation status data are not received in step S110 (N), the process proceeds to step S90.

Meanwhile, when the first and second hard disk operation state data are received (Y), the microcontroller 250 reads the first and second hard disk operation state data from the communication port (S120).

Next, the microcontroller 250 assembles the LED display data (S130).

The assembly process of the LED display data will be described in detail with reference to FIG. 5.

First, it is determined whether the first hard disk state data is in a normal state by the microcontroller 250 (S131).

For example, in FIG. 3, it is checked whether the number 1 data D1 representing the state of the first hard disk hdc1 is a'U'.

In the step S131, if the first hard disk state data is in a normal state (Y) (that is, if the first data D1 is a'U' character), the microcontroller 250 turns on the first hard disk normal display LED ( 260) is configured to turn on (S132) [for example, 1 is substituted for a data variable. That is, data is configured to turn on the first hard disk normal display LED 260 as a binary number (0000 0001)].

Subsequently, it is determined whether or not the second hard disk status data D2 in the status report file is in a normal state by the microcontroller 250 (S133).

For example, in FIG. 3, it is checked whether the number 2 data D2 representing the state of the second hard disk hdd1 is a'U'.

In the step S133, if the second hard disk state data is in a normal state (Y) (that is, if the second data D2 is'U'), the microcontroller 250 turns on the second hard disk normal display LED ( 270) is configured to turn on the data (S134) (for example, 4 is added to the data variable. That is, as the binary number (0000 0100) is added, data is configured to turn on the second hard disk normal display LED 270].

In this case, the addition is performed in order to set only bit 3 of the data variable to '1' without affecting the display data of the first hard disk (hdc1) has already been assigned to the data variable.

Meanwhile, in the step S131, if the first hard disk state data is in an abnormal state (N) (that is, if the first data D1 is not'U'), the microcontroller 250 is more than the first hard disk. After configuring the data to turn on the display LED 260' (S135) (for example, 2 is substituted for the data variable. That is, data is configured to turn on the first hard disk abnormality display LED 260' as a binary number (0000 0010)], and the process proceeds to step S133.

Meanwhile, in the step S133, if the second hard disk state data is in an abnormal state (N) (that is, if the second data D2 is not'U'), the microcontroller 250 is more than the second hard disk. Data is configured to turn on the display LED 270' (S136) (eg, 8 is added to the data variable. That is, the data is configured to turn on the second hard disk error display LED 270' as a binary number (0000 1000)].

Next, the microcontroller 250 is assembled with the LED display data of the first hard disk normal display LED 260, the first hard disk abnormal display LED 260', the second hard disk normal display LED 270, and the second. The operation of these LEDs is controlled by outputting the hard disk abnormality indication LED 270' (S140).

Subsequently, the microcontroller 250 determines whether there is an abnormality in at least one of the first and second hard disks (S150).

When an error occurs in at least one of the first and second hard disks in step S150 (Y), the microcontroller 250 operates the buzzer 230 to generate an alarm sound (S160), and the step S90 ).

On the other hand, when the initialization switch is turned on in step S90 (Y), the microcontroller 250 initializes by turning on the first hard disk normal display LED 260 and the second hard disk normal display LED 270. (S170), the buzzer 230 is turned off (S180).

Subsequently, the microcontroller 250 performs a debounce process (S190), and it is determined whether or not the initialization switch 240 is turned on (S200).

When the initialization switch 240 is turned off (N) in the step S200, the microcontroller 250 performs a debounce process (S210), and then the process proceeds to the step S90.

On the other hand, the execution method of the processor and the microcontroller implementing the method of displaying the hard disk status of the present invention is periodically, for example, once every hour or once every 30 minutes by setting a timer in the OS of the server S. You can use how to do it. Or, whenever the soft-RAID that manages the hard disk is activated, it can be activated immediately after each operation and monitor the status report file. However, if the server is configured as a web-server, the home-page providing service is continuously performed. Therefore, if the present invention is applied to a program that displays the status of the hard disk on the home-page, a greater effect can be obtained. The program that displays the status of the hard disk on the home-page can be checked remotely because the hard disk information is displayed on the home-page, and it is executed every time the user uses the home-page. When the server's hard disk status display system is operated together, a warning is output from the display device 200 even if the manager does not directly check the home-page, so that the manager can be actively informed of the device status.

6 shows the results of configuring and testing the hard disk status display system of the present invention.

Fig. 6A shows that both hard disks (a first hard disk and a second hard disk) of the server S are normal.

6(b) shows that the connector of the second hard disk of the two hard disks of the server S was deliberately disconnected, and an abnormality occurred as the red of the LEDs indicating the state of the second hard disk was lit. Informing.

By using the hardware of the display device 200 and the processor 100 of the server S through the above process, the status of the hard disk devices can be actively and intuitively notified to the administrator, so that it has almost the same function as the expensive hardware RAID system. Can be equipped with. Therefore, there is an advantage that it can significantly increase the stability of the server and the management efficiency of the administrator by supplementing the shortcomings of the soft-RAID system, in which only the administrator must check the status report file to know the error situation.

According to the system and method for displaying the hard disk status of the server using the serial port according to the embodiment of the present invention configured as described above, the processor opens a status report file for recording the status of the first and second hard disks in a read mode to After extracting the operation status data of the first and second hard disks in the report file, the status report file is closed, and the serial port of the server is opened to determine whether the serial port is in use, and if not in use, the first and second hard disks Outputting disk operation status data to the serial port, and closing the serial port; A display device is connected to the processor through the serial port, and the first and second hard disk operation state data are read through a communication port to assemble LED display data, and the first and second display data are based on the assembled LED display data. , 2 By being configured to display the operating status of the hard disk, it is possible to immediately inform the administrator of the status of the hard disk device by using a minimum amount of hardware, similar to the hardware RAID, and has excellent flexibility compared to the method using a parallel port.
