Scenario
When High Availability Manager detects a heartbeat connection failure in your high-availability (HA) cluster, it may display an error message such as "An abnormality occurred in the heartbeat connection." When this happens, the failover mechanism is suspended. In such cases, you should immediately check the connection between the two nodes.
Solution
- Check the physical heartbeat connection.
- Verify the network cable status: Ensure the network cable used for the heartbeat connection is securely connected and not loose, damaged, or oxidized.
- Use a direct connection: Make sure the heartbeat cable directly connects the two nodes without passing through any network devices (such as switches).
- Check the passive node status.
- Power status: Ensure the passive node is powered on and operating normally. A powered-off or unresponsive node will result in a heartbeat disconnection.
- Network interface configuration: Verify that the network interface used for the heartbeat connection is configured correctly (e.g., no DHCP issues or IP conflicts).
- Restart the passive node: Restarting the passive node may help clear abnormal statuses.
- Review system logs for further diagnosis.
- Open QuLog Center and review system logs related to high availability to identify the root cause of the heartbeat connection issue.

场景
当 High Availability Manager 检测到您的高可用性（HA）群集中的心跳连接故障时，可能会显示错误信息，例如“心跳连接出现异常”。发生这种情况时，故障转移机制会暂停。在这种情况下，您应立即检查两个节点之间的连接。
解决方案
- 检查物理心跳连接。
- 验证网络电缆状态：确保用于心跳连接的网络电缆连接牢固，没有松动、损坏或氧化。
- 使用直接连接：确保心跳电缆直接连接两个节点，不经过任何网络设备（如交换机）。
- 检查被动节点状态。
- 电源状态：确保被动节点已开机并正常运行。断电或无响应的节点会导致心跳连接中断。
- 网络接口配置：验证用于心跳连接的网络接口配置正确（例如，没有 DHCP 问题或 IP 冲突）。
- 重启被动节点：重启被动节点可能有助于清除异常状态。
- 查看系统日志以进一步诊断。
- 打开QuLog Center并查看与高可用性相关的系统日志，以识别心跳连接问题的根本原因。
