Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
Example one
As shown in fig. 1-2, the present invention provides a method for implementing BMC dual activity of a server, including:
s1, setting a first logic partition and a second logic partition in an EEPROM chip of the BMC, wherein the first logic partition is a BMC working version, and the second logic partition is a BMC activated version;
s2, monitoring the BMC working state in real time, judging whether the BMC works abnormally, if so, executing a step S3, and if not, executing a step S2;
and S3, the second logic partition receives the command to replace the BMC working version in the first logic partition and enters a working state.
In step S1, the BMC version in the first logical partition is a working version, and the BMC version in the second logical partition is an active version, and both versions are the same, and may be in a replacement state or a replaced state in real time.

The state of the BMC version can be written into a state register for storage, and the BMC working version state is determined by checking the value of the state register. For example, 00 is active, 01 is inactive, and 10 is active.
And setting two pointers in the state register, wherein the first pointer points to the BMC working version state in the first logic partition, the second pointer points to the BMC activated version state in the second logic partition, and the BMC working version state and the BMC activated version state are determined according to the value stored in the state register.
In step S3, the second logical partition receives the command to replace the B MC working version in the first logical partition, and the entering into the working state specifically includes: when the watchdog monitors that the BMC works abnormally, a command is sent to the second logic partition, and after the second logic partition receives the command, the BMC working version of the first logic partition is replaced, and the BMC enters a working state.
