Method and system for detecting hard disk information before startup of server and storage medium

The invention relates to a method for detecting hard disk information before startup of a server. The method comprises the following steps: S1, adding a logic switch between an out-of-band system and a hard disk backboard; s2, when the server is powered on and not started, using the standby voltage of the server to supply power to the out-of-band system, the hard disk backboard and the logic switch; s3, enabling the logic switch to be connected with the SMBus, enabling the out-of-band system to read the connection state of the SMBus and then directly communicate with the hard disk backboard, and collecting and detecting hard disk information; and s4, starting up the server, disconnecting the logic switch from the SMBus after starting up, and completing information collection and detection. Hard disk information is monitored and collected before the server is started up, hard disk exceptions are found and processed in advance, and hard disk faults after the server is started up are reduced. 本发明涉及一种服务器开机前硬盘信息检测
