The rack server is used for uniformly managing and controlling a plurality of hosts by transversely placing the hosts in the chassis, so that the storage space of the hosts is saved. The main benefit of saving space is to facilitate centralized maintenance and management, whereby the cost for hosting in the machine room is also lower.
In the past, no matter the remote control is required or when each Unit Under Test (UUT) inserted in a rack server is tested, the MAC address (i.e., physical address) and the IP address of each dut are obtained, however, when the operator submits the information, if the unit to be tested inserted in the rack server is not the model produced by the company to which the operator belongs, the information related to the unit to be tested corresponding to the model produced by the company to which the operator belongs cannot be submitted exactly, therefore, for the tester, the rack server acts as a black box, and the physical addresses of the units to be tested are unknown.
The tester should actually disassemble each unit to be tested installed on the rack server, then query the physical address corresponding to each unit to be tested, manually record the physical address corresponding to each unit to be tested, and finally test the unit to be tested according to the physical address of each unit to be tested and the internet protocol address. Alternatively, commercially available software such as NMAP may be used to scan all ip addresses of the dut plugged into the rack server, and the ip addresses obtained by this method are not verified and therefore are not highly accurate, so that a solution is needed.

FIG. 2 is a flow chart illustrating an embodiment of the method for detecting IP addresses and physical addresses of the present invention.
[ detailed description ] embodiments
Referring to fig. 1, the embodiment of the method for detecting ip addresses and physical addresses of the present invention is adapted to detect an ip address and a physical address of each of a plurality of dut 11 installed in a rack server 1, and is implemented by a test server 2. The rack server 1 is further provided with an exchanger 12 and a power distribution unit 13 for controlling the power of each unit under test 11 and electrically connected to the exchanger 12. Each DUT 11 is electrically connected to the switch 12 and the power distribution unit 13. In the present embodiment, the test server 2 is electrically connected to the switch 12 and includes a Dynamic Host Configuration Protocol (DHCP) server 21 and a processor 22, and the processor 22 executes an application program containing a plurality of instructions to implement the method for detecting an ip address and a physical address of the present invention, but is not limited thereto.
Referring to fig. 1 and 2, an embodiment of the method for detecting an ip address and a physical address of the present invention includes the following steps.
In step 30, for each DUT 11, when the test server 2 receives an IP address request including a physical address from the DUT 11, the test server 2 assigns and transmits an IP address to the DUT 11 and stores the physical address and the assigned IP address in a first mapping table.
In step 31, for each dut 11, when the test server 2 receives a power-on request from the dut 11, the test server 2 transmits power-on configuration data associated with the power-on of the dut 11 to the dut 11. In this embodiment, the boot configuration data includes a boot management program and a core file.
In step 32, the test server 2 detects a connection status of at least one communication port corresponding to each unit under test 11 by using a Network mapping (Nmap) technique to determine whether each unit under test 11 is executing an operating system. When the test server 2 determines that each unit under test 11 is executing the operating system (i.e. the connection status of at least one communication port corresponding to each unit under test 11 is connected), the process proceeds to step 33. Otherwise, the flow returns to step 30. In this embodiment, the at least one communication port includes a Secure Shell (SSH) communication port, and the SSH can provide a Secure transmission and use environment for a Shell (Shell) on the computer. The SSH protocol can effectively prevent the information leakage problem in the remote management process, and all the transmitted data can be encrypted through the SSH protocol, so that the data leakage can be prevented. It should be noted that, when testing the units 11 to be tested installed on the rack server, the tester should test each unit 11 at the same time, so that, in the testing stage, the ip address and the physical address corresponding to each unit 11 to be tested are known, and each unit 11 to be tested should enter the operating system (i.e., each unit 11 to be tested should be executing the operating system), so if there is at least one unit 11 to be tested that does not enter the operating system, the flow should return to step 30 again until each unit 11 to be tested enters the operating system. That is, in step 32, the test server 2 must confirm that all of the DUTs 11 issuing IP address requests in step 30 have entered the operating system before proceeding to step 33.
In step 33, the test server 2 sets the IP address corresponding to each physical address in the first mapping table as a static IP address, reads a corresponding relationship between the physical address and the connection port of each DUT 11 from the switch 12, and stores the connection port corresponding to the physical address in the first mapping table. In this embodiment, the test server 2 sets the IP address as the static IP address by storing each physical address in the first mapping table and the IP address assigned thereto in a static IP address table included in a dynamic host configuration protocol (DHCP configuration file). It should be noted that the test server 2 automatically reads the corresponding relationship between the physical address and the connection port of each unit under test 11 from the switch 12 by executing at least one of the instructions of the application program, and stores the connection port corresponding to the physical address in the first mapping table.
In step 34, the test server 2 sends a power control command associated with the dut 11 to the power distribution unit 13 to restart the dut 11 of the rack server 1. The power distribution unit 13 first stops supplying power to the units under test 11 to turn off the units under test 11 according to the power control command, and then supplies power to the units under test 11 again to turn on the units under test 11.
In step 35, for each DUT 11, when the test server 2 receives the IP address request including the physical address from the DUT 11, the test server 2 assigns and transmits the static IP address corresponding to the physical address to the DUT 11 according to the static IP address table.
In step 36, the test server 2 identifies a plurality of types of dut 11, which are Baseboard Management Controllers (BMCs), according to the physical addresses of the dut 11 stored in the first mapping table. As known to those skilled in the art, for each two physical addresses with partially identical codes, the type of the unit 11 to be tested corresponding to the physical address with the larger hexadecimal value is the BMC, so the test server 2 can identify the unit 11 to be tested corresponding to the physical address with the larger hexadecimal value as the BMC from each two units 11 to be tested with the partially identical codes according to the physical addresses.
In step 37, the test server 2 sends a plurality of inquiry requests to the units under test 11 according to the identified ip addresses of the units under test 11 whose kind is the bmc. In the embodiment, each query request includes an Intelligent Platform Management Interface (IPMI) instruction.
In step 38, when the test server 2 receives at least one reply message from at least one of the units under test 11 of the baseboard management controller type, the test server 2 verifies each of the at least one unit under test 11 as a successful connection. And for each of the units under test 11 that has not received a response to the corresponding inquiry request within a predetermined period of time, the test server 2 verifies it as a connection failure.
In summary, the method for detecting IP addresses and physical addresses of the present invention automatically assigns the IP address corresponding to each physical address according to the physical address corresponding to each DUT 11 through the test server 2, and sets the IP address corresponding to each physical address as the static IP address to automatically obtain the IP address and physical address information corresponding to each DUT 11. In addition, the test server 2 transmits the query requests to the units under test 11, respectively, and when the test server 2 receives the at least one reply message from at least one of the units under test 11, the test server 2 verifies each of the at least one unit under test 11 as successful connection, so as to know which bmcs are probably abnormal, thereby achieving the purpose of the present invention.
The detailed description and examples of the present invention are given above with reference to the accompanying drawings, but the scope of the present invention is not limited thereto, and the equivalent modifications and variations within the scope of the claims of the present invention should be considered as falling within the scope of the present invention.
