Function test optimization method of dual-use hard disk backplane of server

The present invention discloses a function test optimization method of a dual-use hard disk backplane of a server. The function test optimization method comprises the following steps: 1) a machine is started from a UEFI (Unified Extensible Firmware Interface) shell; 2) the UEFI starts a script and guides the script into a test USB (Universal Serial Bus) flash disk; 3) the script is subjected to examination that whether an NVME (Non-volatile Memory Express) PASS marked file exists in the script; if not, an NVME hard disk starts to be tested, and the NVME PASS marked file is written if the test passes; if yes, an operation system is called to guide the file into the operating system for the test of the module function of a common hard disk; 4) if the test of the module function of the common hard disk passes, the function of the whole dual-use hard disk backplane is normal, the dual-use hard disk backplane is a good product, otherwise, the dual-use hard disk backplane is a defective product. Compared with the prior art, the function test optimization method solves the problem of long consumed time as the hard disk needs to be replaced in a shutdown state and the operating system needs to be started twice due to two parts of the existing test, thereby saving the testing time and the labor cost; moreover, the function test optimization method is high in degree of automation.
