事件摘要

如果MetroCluster 切换操作失败、则会显示此消息。故障可能为部分或完整。

验证

事件日志

event log show -event *switchover*

命令行：

在尝试执行切换操作的集群上运行以下命令。

metrocluster operation show

Operation: switchover
State: failed
Start Time: xxx
End Time: xxx
Errors: Failed to validate the node and cluster components before the switchover operation.
xxx(non-overridable veto): <Failure reason>

解决方法

  1. 验证MetroCluster 的当前状态

metrocluster node show

  1. 检查SVM是否联机：

vserver show

  1. 按照MetroCluster operation show输出中所述的恢复步骤进行操作。

  2. Please contact NetApp Technical Support or log into the NetApp Support Site to create a case. Reference this article for further assistance.

追加信息

注意： MetroCluster operation show输出仅会报告上次MetroCluster 操作。如果在切换失败后运行了后续MetroCluster 操作、则输出将与故障无关。

要获取有关先前MetroCluster 操作的更多详细信息、请执行以下操作：

  1. 运行MetroCluster operation history show命令查看所有先前的MetroCluster 操作：

metrocluster operation history show -fields operation,start-time,state,operation-uuid

  1. 在输出中、确定失败或部分失败操作的operation-uuid：

ClusterA::> metrocluster operation history show -fields operation,start-time,state,operation-uuid
operation-uuid                       operation           start-time         state
------------------------------------ ------------------- ------------------ ----------
b6fe95a4-dc12-11ec-881e-00a0985bd305 switchover-simulate mm/dd/yyyy hh:mm:ss successful
bffaf8b3-b9a4-11ec-881e-00a0985bd305 switchover-simulate mm/dd/yyyy hh:mm:ss successful

2f258258-59b4-11e9-b2d2-00a0985bd305 switchover          mm/dd/yyyy hh:mm:ss completed-with-manual-recovery-needed

  1. 使用已标识的操作uuid运行MetroCluster operation history show命令：

metrocluster operation history show -operation-uuid <operation-uuid>

ClusterA::> metrocluster operation history show -operation-uuid d719de7e-5a23-11ea-93d9-00a0985bd305
      Operation: switchover
          State: failed
         Errors: Failed to validate the node and cluster components before the switchover operation.
