Method and device for server self-healing

Abstract

Provided is a server self-healing method, said method comprising: a baseboard management controller (BMC) receives exception information sent by a basic input / output system (BIOS), said exception information comprising memory exception type and exception memory module identifier; according to said exception information, the BMC or system management module (SMM) generates quarantine memory information, and processes the board accordingly; the BMC sends the quarantine memory information to the BIOS, said quarantine memory information being used for instructing the BIOS to quarantine the corresponding exception memory. By means of the coordination of the BMC, the BIOS, and the SMM, the described solution accomplishes automatic self-healing of a server, which reduces the possibility of on-site manual intervention and operation and restores the server to a state of normal operation as quickly as possible.

Description

technical field [0001] The invention relates to the server field, in particular to a server self-healing method and device. Background technique [0002] At present, operators are facing huge challenges. They must be able to quickly integrate network resources to provide users with the latest services, and at the same time must reduce network procurement costs, operation and maintenance costs, and fault recovery time. A large number of servers owned by operators are installed with a large amount of memory, because memory failures lead to server abnormalities, which reduces the stability of services provided by operators and increases the recovery time and maintenance costs of failures. [0003] In the server, the BMC (Baseboard Management Controller, out-of-band management module) monitors the working status of the server, manages the power-on and power-off of the server, handles it in time and issues an alarm when the server is abnormal. BMC exists as an independent firmwa...

AI Technical Summary

Problems solved by technology

The reliability of the server's memory directly affects the stability and reliability of the board. Memory problems directly lead to business interruption, and in serious cases, there will be downtime

Although most high-performance and high-reliability servers use memory with ECC (Error Checking and Correcting, error checking and correction) functions, the improvement of system reliability is also limited.

There are mainly the following aspects: First, after a correctable ECC error occurs, although the memory with this ECC function can automatically correct the error, if it occurs frequently, it means that there is a serious hidden danger in the memory, so this automatic error correction The processing method is relatively passive, because serious hidden dangers in the system have not been ruled out; second, after uncorrectable ECC or other unrecoverable errors occur, the system will have serious consequences such as blue screen or downtime. If such serious consequences do not involve out-of-band , only the on-site personnel can shut down the server and replace the memory
