Description

A method and device for realizing server BMC active-active

Technical field

The present invention relates to the field of server BMC design, and in particular, to a method and device for realizing server BMC dual-activity.

Background technique

As the functions of server products become increasingly powerful, BMC, as the management center, is also playing an increasingly important role. It plays its value at all times from daily server function management, system remote debugging and system log analysis. While enjoying the convenience brought by BMC, there is also the risk of damage to BMC. Once BMC fails, the server will be derailed from the control platform and lose contact.

During the server debugging phase, the BMC chip fails due to artificial refresh signal interruption or sudden power outage, causing the entire server self-check to fail to start, causing the entire machine to stop working; during the server operation phase, the BMC function fails, As a result, the entire server is lost, and the computer room management system cannot obtain the running status of the server, resulting in service interruption and management failure.

At present, BMC chips are all single versions. One chip can only accommodate one version and has no restore and failure activation functions. Once the BMC function fails, the entire server will stop working, which is not conducive to improving the server's work and management efficiency.

Embodiment 1

As shown in Figures 1 and 2, the present invention provides a method for realizing server BMC dual-active, including:

S1, set the first logical partition and the second logical partition in the EEPROM chip of BMC, where the first logical partition is the BMC working version and the second logical partition is the BMC activated version;

S2, monitor the BMC working status in real time and judge whether the BMC is working abnormally. If the judgment result is yes, execute step S3. If the judgment result is no, execute step S2;

S3: The second logical partition receives the command, replaces the BMC working version in the first logical partition, and enters the working state.

Among them, in step S1, the BMC version in the first logical partition is the working version, and the BMC version in the second logical partition is the activated version. The two versions are the same and can be in a state of replacing and being replaced in real time.

In step S2, the real-time monitoring of the BMC working status is specifically: the watchdog in the BMC monitors the status register value of the BMC working version in real time. The status of the BMC version will be written to the status register and stored. The status of the BMC working version can be determined by checking the value of the status register. For example, 00 means active, 01 means disabled, and 10 means working.

Set two pointers in the status register. The first pointer points to the BMC working version status in the first logical partition, and the second pointer points to the BMC activated version status in the second logical partition. The BMC working version status is determined based on the value stored in the status register. and BMC activation version status.

In step S3, the second logical partition receives the command, replaces the BMC working version in the first logical partition, and enters the working state. Specifically: when the watchdog detects that the BMC is working abnormally, it sends the command to the second logical partition, and the second logical partition receives the command. After receiving the command, replace the BMC working version of the first logical partition and enter the working state. The command may be implemented through an IPMI (IntelligentPlatform Management Interface) command.

The invention effectively solves the problem of server work stopping due to BMC failure due to a single version of the BMC chip, and effectively improves the work and management efficiency of the server.

S2, monitor the BMC working status in real time and judge whether the BMC is working abnormally. If the judgment result is yes, execute step S3. If the judgment result is no, execute step S2;

S3, the second logical partition receives the command, replaces the BMC working version in the first logical partition, and enters the working state;

S4, set up a third logical partition in the EEPROM chip of the BMC. The third logical partition stores the BMC version image file. When an abnormal working status of the BMC is detected, the BMC version image file is decompressed and refreshed to activate the BMC version again.

In step S4, the BMC version image file can be the BMC version stable version or the latest BMC version. In order to achieve efficient management, the BMC version stable version is generally preferred, so that the BMC working version or BMC activated version can be more stable after the refresh. . The space occupied by the third logical partition can be half of the second logical partition. The BMC version image file is a compressed package in zip format. Use the BMC built-in decompression tool to decompress the zip file first. The decompressed file defaults to a bin file, and then use The BMC writing tool writes the decompressed bin file to the first logical partition (or second logical partition) to be refreshed. The first logical partition and the second logical partition can be encoded to realize the first logical partition and the second logical partition. The difference between the second logical partition.

In the same way, when the BMC activated version of the second logical partition is in the working state and the BMC version in the first logical partition is refreshed, once the BMC abnormality occurs again, the BMC version of the first logical partition (the original BMC working version, is now in Activated state) will replace the BMC version of the second logical partition (the original BMC activated version, now in the working state), and at the same time, the BMC version in the second logical partition (the original BMC activated version, now in the working state) will work abnormally again. in an invalid state) to refresh.

The BMC working version automatically backs up the configuration information when working and saves it in the configuration file. You can save the BMC configuration information into a config file (configuration file) through the BMC web interface and save it). When the BMC version image file is decompressed and refreshed, BMC is realized. After the reactivation of the version is completed, import the configuration file to realize BMC's management connection to the server and ensure that server management is not dropped.

The present invention encapsulates the third logical area in the EEPROM of the BMC chip, and the third logical partition stores the BMC version image file. When an abnormality in the BMC working status is detected, the BMC version image file is decompressed and refreshed to make the BMC in the BMC chip work. The version and BMC activation version are activated in real time. Once the BMC works abnormally, the original BMC working version can be refreshed and replaced, ensuring the efficiency and reliability of server operation.
