问题描述

更换故障节点上的主板后，HA 互连保持离线状态。
系统反复出现链路抖动，最终停机。

系统 ha-interconnect status show 的输出：

Node A: Logical Link status is Down Node B: Logical Link status is Down NODE-A slot 0: Interconnect HBA: Generic OFED Provider Port Name: ic0a GID: fe80:0000:0000:0000:0000:0000:0000:0104 Base LID: 0x104 Active MTU: 8192 slot 0: NTB Interconnect (PLX87b0) Max HW Data Rate: PCIe Gen 3 x 8 HW Data Rate: PCIe Gen 1 x 0 SW Data Rate: PCIe Gen 1 x 0 Logical Link: Down <<<<<< Port State: Enabled

NODE-B slot 0: Interconnect HBA: Generic OFED Provider Port Name: ic0a GID: fe80:0000:0000:0000:0000:0000:0000:0105 Base LID: 0x105 Active MTU: 8192 slot 0: NTB Interconnect (PLX87b0) Max HW Data Rate: PCIe Gen 3 x 8 HW Data Rate: PCIe Gen 1 x 8 SW Data Rate: PCIe Gen 3 x 0 Logical Link: Down <<<<< Port State: Enabled

通过从底盘上卸下控制器来执行 HA 对的硬电源循环
- HA 对暂时恢复但出现震荡并再次失败
在插入伙伴节点的情况下，尝试对节点 A 进行主板重新就位，但没有变化
在插入伙伴节点的情况下，对节点 A 执行了主板更换，但没有变化
在机箱中插入伙伴节点的情况下，对节点 B 执行了主板重新就位，但没有变化
