MetroCluster切换失败
适用场景
- MetroCluster IP
- ONTAP 9
问题描述
- 启动协商切换(NSO)后、操作失败并显示错误消息
Cluster_A::> metrocluster operation show
Operation: switchover
State: successful
Start Time: 5/24/2023 06:35:38
End Time: 5/24/2023 06:35:44
Errors: Failed to execute the switchover operation for the node components. Cluster_A (fatal): Unable to determine the result of the negotiated switchover operation for the remote nodes. Ensure the remote nodes are shut down and then retry the switchover operation with the "-forced-on-disaster true" option.- MetroCluster处于不一致状态
