Redundancy switching method of chassis management board, storage medium and chassis management board

Abstract

The invention discloses a redundancy switching method of a chassis management board, a storage medium and a chassis management board. The storage medium and the chassis management board are executed by the local management board. The method comprises the following steps of: sending a heartbeat signal to the opposite management board at a fixed time; judging whether it is mandatory or not; if the mandatory standby instruction sent by the management platform is received, judging to be mandatory standby, and the state being switched to be standby; timing detecting of heartbeat signals, informingsignals and in-situ signals sent by the opposite end management board; judging whether it is used primarily or not; when it is standby, judging whether the working state of the opposite management board is changed according to the detected heartbeat signal, the notification signal and the on-site signal; when the working state of the peer management board changes, the state being switched to be standby. The invention realizes that the software forces the switch management board to be in standby state, and the switch of the main standby state when the management board is abnormal.

Description

technical field [0001] The invention belongs to the field of redundant switching of chassis management boards, and in particular relates to a redundant switching method of the chassis management board, a storage medium and the chassis management board. Background technique [0002] Redundancy technology is a commonly used technical means in the reliability design of computer systems. In order to maintain the long-term stable and reliable operation of the system, a redundant system with dual management boards is often used. When the system is running, set one of the management boards as the master and the other as the backup. If the main management board fails and cannot work normally, switch the standby management board to continue working as the main one, thus ensuring the normal operation of the entire system. However, the existing redundancy management mechanism has the following defects: the existing chassis management board redundancy management technology generally sw...
