状态信息

适用场景

  • ONTAP 9
  • 节点发出HA组通知(控制器接管完全自动)警报

事件摘要

如果成功自动接管配对节点、则会显示此消息。

  • 当节点接管其配对节点时、它会继续提供并更新配对节点的聚合和卷中的数据。HA可用性概述

默认情况下、在以下任何情况下都会自动发生接管:

  • 导致崩溃的节点上发生软件或系统故障。HA对控制器会自动故障转移到其配对节点。

    • 配对节点从崩溃中恢复并启动后、节点将自动执行交还、使配对节点恢复正常运行。

  • 节点发生系统故障、节点无法重新启动。例如、当某个节点因断电而发生故障时、HA对控制器会自动故障转移到其配对节点、并从运行正常的存储控制器提供数据。

解决方法

  1.  验证节点是否仍 处于接管状态 正在等待交还
    1. 如果 正在等待交还、 请按照 交还的工作原理 执行手动交还
    2. 如果节点仍 处于接管 状态且尚未启动、NetApp支持部门将请求SP/BMC提供日志以供进一步分析。
