MetroCluster IP 远程站点多个磁盘失败
适用于
- ONTAP 9
- MetroCluster
问题
- 已在群集交换机的 MetroCluster IP 端口上禁用流量控制。
- 多磁盘故障事件：报告来自 Cluster1-1a 的 HA 组通知（文件系统磁盘未响应）错误。
- 我们可以在集群中看到以下错误

站点 A：Cluster2
节点：
Cluster2-1a - 没有问题
Cluster2-1b - 没有问题
站点 B：Cluster1
节点：
Cluster1-1a ---> 所有远程磁盘都出现故障/缺失
Cluster1-1b ---> 没有问题
- 存储和交换机没有潜在的硬件问题。
