Out-of-band management method and device for multi-path server system

The invention discloses an out-of-band management method and device for a multi-path server system, in the method, each CPU in the multi-path server system is connected with an out-of-band access device through an LPC bus, the out-of-band access device is further connected with each CPU through an IC bus, and in the out-of-band management method, the LPC bus and the IC bus are jointly used as an out-of-band management channel, and the out-of-band access device is connected with each CPU through an IC bus. Wherein the out-of-band access device accesses RAS information of different CPUs through the IC bus channel, and the IC bus channel is configured to be an out-of-band access channel of the out-of-band access device to the CPUs; each CPU transmits the actively reported RAS information to the out-of-band access device through the LPC bus channel, and the LPC bus channel is configured to be a CPU active report information channel. The method can realize efficient bidirectional access of out-of-band management,
