MetroCluster 切回失败—AutoSupport 消息

适用场景

• MetroCluster
• ONTAP 9
• 切回失败

•  callhome.mcc.switchback.failed:EMERGENCY

事件摘要

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

验证

解决方法

1. 验证远程集群的状态
   • 修复完成后、应启动所有节点
2. 解决"Errors"部分中发现的任何问题、然后重试切回
3. 请联系NetApp技术支持并参考此文章以获得进一步帮助

追加信息

注意： MetroCluster operation show输出仅会报告上次MetroCluster 操作。如果在切回失败后运行了后续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

2. 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
------------------------------------ ---------- ------------------  ----------
ce744f8d-3926-11e7-9a03-00a0985bd73d switchback mm/dd/yyyy hh:mm:ss failed
4d33e0bb-3566-11e7-97f2-00a0985bd73d switchback mm/dd/yyyy hh:mm:ss failed

3. 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 ce744f8d-3926-11e7-9a03-00a0985bd73d
