A method and apparatus for determining a target hard disk backplane

The invention discloses a method and a device for determining a target hard disk backplane. The method comprises the following steps: firstly, obtaining preset display information of a target I2C interface including front/rear data of a hard disk backplane actually connected to the target I2C interface and a preset sequence number; Then, according to the preset display information and the preset display information-hard disk backplane correspondence table of each I2C interface of the motherboard, determining a target hard disk backplane corresponding to the preset display information. As can be seen, since the default display information for the target I2C interface is no longer the I2C interface location, but according to the front/back data and the preset serial number of the actual connected hard disk backplane, when the hard disk backplane or the hard disk fails, the preset display information-hard disk backplane correspondence table of each I2C interface of the main board stored in advance is searched ba
