Background
If the hard disk backboard of the front window of the server case is a hard disk backboard designed by 2 hard disk backboard with Expander (expansion) chips and is matched with a single RAID card of 8i, the phenomenon that the hard disk ordering of backboard 1 and backboard 2 is opposite occurs probabilistically, once the hard disk is fixed after ordering is completed under the system, the hard disk cannot return any more, and the correct hard disk ordering can be guided back by switching 2 backboard by manual mode and then electrifying again, for example: the single 8i RAID card has 2 output ports (ports) which are respectively port 0 and port1, and mainly provides uplink bandwidth links for the hard disk backboard with an expander chip, if the expander chip hard disk backboard is a 12-port hard disk and a 24-port hard disk configuration is needed in the front window of a server, then the combination of 2 hard disk backboard with the expander chip is needed to be integrated into a 24-port hard disk, because the single 8i RAID card is only used, the port 0 and the port1 are respectively connected to the same 2 hard disk backboard with the expander chip, the front window of the server is divided into an upper layer and a lower layer, the port 0 of the 8i RAID card in the system is the 12-port hard disk backboard with the expander chip connected to the upper layer, the port1 is the 12-port hard disk backboard with the expander chip connected to the lower layer, the hard disk sequence recognized under the normal system is the HDD 0-HDD 11, and the lower layer is the HDD 12-23. However, the priority order of port 0 and port1 is not set in the design of the single 8i RAID card, but the arrangement order of the access IDs is obtained according to the RAID card and the 2 hard disk backplanes of the Expander, because the port 0 and the port1 of the 8i RAID card are connected with the backplanes of the same design of 2 blocks, if the port1 of the RAID card preferentially recognizes the 2 nd hard disk backplane and then recognizes the 1 st hard disk backplane, the RIAD card and the 2 nd hard disk backplanes complete the establishment of the access list and record the access list in the FRU ROM of the RAID, and the access of the hard disk under the OS is fixed and can not be changed after the system is started every time.

And S3, responding to the completion of the power-on of the hard disk backboard, and initializing the firmware of the hard disk backboard where the first sequence is located in the identification sequence.
S4, responding to the completion of the firmware initialization of the hard disk backboard, initializing the firmware of the next hard disk backboard in the identification sequence, and repeating the current steps until the firmware initialization of all the hard disk backboard is completed.
When an 8i PCIe RAID card is inserted into a PCIe card slot on a server main board, 2 output ports 0 and 1 are shared, 2 SAS x4 signal bandwidths can be provided for uplink interface connection of two 12-port expander hard disk backplates, 12 SAS/SATA hard disks are expanded by expander chips on the hard disk backplates, the arranged disk sequence of the two hard disk backplates is 0-11 in the upper layer, and the lower layer is 12-23. The BMC chip is communicated with the PCIe RAID card through the I2C bus to read the information about the Expander chip on the RIAD card and the downstream Expander hard disk backboard, and the information can be used for inquiring the unclosed ID under the Expander chip and distinguishing the disk sequence of the 1 st or 2 nd Expander hard disk backboard.
The invention is mainly used for the condition that a single 8I RAID card is connected with two Expander hard disk backplanes, and also can be used for the condition that a plurality of RAID cards are connected with a plurality of Expander hard disk backplanes, and the invention is mainly described in the first condition, firstly, the I2C bus of the BMC is connected with the I2C buses on the Expander chips of the two backplanes, so that the BMC can inquire the two backplanes through the I2C buses and know which block is connected to the upper layer and which block is connected to the lower layer, the FW code (stored in the flash) can be modified through the Expander SDK software, the FW code communicated between the BMC and the Expander chips is added into the source code (Expander source code) of the Expander chips, and the operation of initializing the firmware is stopped when the power-up is completed, and the firmware code can be initialized after the BMC is required to inform the Expander through the I2C bus issuing instruction. After the two hard disk backplates are powered up under the system, the firmware codes in the NOR flash are loaded first and the modified firmware codes are executed, after the instruction issued by the BMC is received, the initialization firmware is continuously executed to complete the subsequent mechanism of the Expander chip, the BMC can inquire whether the identification program of the unclosed list of the RAID card and the first hard disk backplate is completed or not, if so, the BMC can issue the instruction again to the 2 nd hard disk backplate to inform the Expander chip of initializing the firmware, and the operation can avoid the problem that the 2 nd hard disk backplate with the same design cannot control the acquisition sequence from the RAID card and the Expander chip and can control which priority is identified for the RAID card port 0 and the port 1.
By the technical scheme, the problem of disorder in the identification of the hard disk backboard can be solved, and time cost and labor cost can be saved.
In a preferred embodiment of the present invention, querying the location of the hard disk backplane connected to the RAID card and setting the identification order of the hard disk backplane according to the location of the hard disk backplane comprises:

adding a firmware code of the hard disk backboard extension chip into an extension chip source code;
and setting the condition for initializing the firmware to the condition that the hard disk backboard is powered on to finish the initialization of the non-execution firmware.
The Expander FW settings on the two backplates are stored in the NOR flash attached and mounted under the Expander chip, firmware can be modified through Expander SDK software to add the FW code communicated between the BMC and the Expander chip into Expander source code, the operation of initializing the firmware is stopped when the power-on is set, and the operation of initializing the firmware can be continued after waiting for the BMC to send a command to notify the Expander through the I2C bus. After the modified Expander FW codes are respectively updated to the NOR flash of the two Expander hard disk backplanes, the Expander hard disk backplanes can be unloaded into firmware attached to the NOR flash after the system is powered on each time, and after the two Expander hard disk backplanes are powered on, the BMC issuing instruction can be waited to be received.
In a preferred embodiment of the present invention, in response to the hard disk backplate powering up being completed, initializing firmware of the hard disk backplate in which the first sequence of the identification sequences is located comprises:

and initializing the firmware on the hard disk backboard in the first identification sequence in response to the hard disk backboard being in the firmware initialization waiting execution state.
The invention solves the problem that when a single PCIe 8i RAID card is used for tie-through configuration and output port 0 and port1 are respectively connected to two hard disk backplates with expanders, the backplates under the connection port1 are preferentially identified to the hard disk, the problem that the probability is generated can be solved without correcting through manual maintenance action, and meanwhile, the operation that after the system is configured, a part of system enters under an OS to check whether the sequence of the hard disk is inconsistent with that of the BIOS is also omitted, so that the problem that the sequence of the hard disk is opposite is solved, and meanwhile, a lot of manpower and maintenance time are saved in production test.
