[0002] In general-purpose server systems, there is usually a large demand for SATA SSDs, and general-purpose servers typically have front-mounted and rear-mounted hard drives. The functions of the front and rear hard drives may differ depending on the application scenario, and the installation and inspection strategies for the front and rear hard drives may also differ during server assembly and re-inspection on the production line. Therefore, it is necessary to distinguish between the front and rear hard drives.

[0003] However, during the server production line testing process, the machine has already been assembled and cannot be disassembled for inspection. Therefore, it is necessary to automatically detect and distinguish the front and rear hard drives in the operating system to improve the efficiency of production line testing.

[0056] In general-purpose server systems, there is usually a large demand for SATA SSDs, and general-purpose servers typically have front-mounted and rear-mounted hard drives. The functions of the front and rear hard drives may differ depending on the application scenario, and the installation and inspection strategies for the front and rear hard drives may also differ during server assembly and re-inspection on the production line. Therefore, it is necessary to distinguish between the front and rear hard drives.

[0057] However, during the server production line testing process, the machine has already been assembled and cannot be disassembled for inspection. Therefore, it is necessary to automatically detect and distinguish the front and rear hard drives in the operating system to improve the efficiency of production line testing.

[0058] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0059] like Figure 1 As shown, this embodiment of the invention provides a method for automatically distinguishing between front and rear hard drives under an OS, including the following steps:

[0060] Step 1: Select the corresponding slot number according to the defined disk order and the number of hard drives in place on the front and rear backplanes to initially determine the front and rear hard drives;

[0061] Step 2: According to the initially determined sequence number of the front and rear hard drives, turn on the position lights of the corresponding hard drives according to their slot numbers;

[0062] Step 3: Detect the level change of the position light and query the I2C address corresponding to the lit position light;

[0063] Step 4: Compare the queried I2C address with the preset actual I2C address of the front and rear backplanes, and finally determine the front hard drive and the rear hard drive based on the comparison results.

[0064] like Figure 2 As shown, this embodiment of the invention provides a method for automatically distinguishing between front and rear hard drives under an OS, including the following steps:

[0065] S1: Check the number of hard drives in place on the front and rear backplanes;

[0066] S2: Check the disk order defined by the expander chip and CPLD on the front and rear backplanes to determine the cascading order of the front and rear hard drives;

[0067] S3: Check the slot number identified under the RAID card in the operating system and generate a slot number table.

[0068] S4: Match the slot number table according to the disk order defined by the CPLD and the number of hard drives in place on the front and rear backplanes, select the corresponding slot numbers, and initially determine them as front hard drives and rear hard drives respectively.

[0069] S5: According to the initially determined sequence number of the front and rear hard drives, turn on the position lights of the corresponding hard drives in turn according to the slot number;

[0070] S6: Detect changes in the level of the position indicator;

[0071] S7: Obtain the unique correspondence table between each slot number, position light number, and I2C address on the hard drive backplane;

[0072] S8: Query the I2C address corresponding to the detected position light in the light number correspondence table, and generate the first I2C address table.

[0073] S9: Query the second I2C address table generated from the predefined real I2C addresses of the front and rear hard disks;

[0074] S10: Compare the first I2C address table and the second I2C address table; if the I2C addresses of the front and rear hard drives are consistent in both tables, the check is correct, and the front and rear hard drives are finally determined.

[0075] In a configuration where front and rear hard drives are cascaded under the same RAID card, the first step is to check the number of hard drives present on the front and rear backplanes in the operating system. Then, check the disk order defined by the expander chip and CPLD on the hard drive backplane to determine the cascading order of the front and rear hard drives. Next, check the slotIDs identified by the RAID card in the operating system to create a slotID table. Match the slotID table according to the disk order defined by the CPLD and the number of hard drives present on the front and rear backplanes, selecting the corresponding slotIDs to initially identify the front and rear hard drives. Then, according to the initially determined sequence numbers of the front and rear hard drives, sequentially illuminate the corresponding SATA hard drive's location LED using the slotID. The CPLD on the hard drive backplane detects changes in the location LED level. Each slot number on the hard drive backplane corresponds to a unique LED number and I2C address. Look up the corresponding I2C address in the CPLD's LED number mapping table to form I2C address table 1; then look up the actual I2C address table 2 defined at the beginning of the design for the front and rear hard drives. By comparing I2C address table 1 with the actual I2C address table 2 of the front and rear hard drives, if the I2C addresses of the different hard drives in the front and rear are consistent in both tables, the check is correct, and the front and rear hard drives can be finally identified.
