如果SnapMirror活动同步复制链路无法完成写入IO、因为集群无法将更改复制到相反站点。
站点 A
在站点A上、复制链路发生故障会导致写入IO处理暂停大约15秒、因为ONTAP会在确定复制链路确实无法运行之前尝试复制写入。15秒后、站点A上的ONTAP集群将恢复读写IO处理。SAN路径不会更改、LUN将保持联机状态。
站点 B
由于站点B不是SnapMirror主动同步首选站点、因此其LUN路径将在大约15秒后变得不可用。
复制链路在时间戳15：19：44处断开。当200秒超时(由Oracle RAC参数disktimeout控制)接近时、Oracle RAC发出的第一条警告会在100秒后到达。

达到200秒表决磁盘超时时间后、此Oracle RAC节点将从集群中退出并重新启动。
