适用于

  • NetApp AFF-A300
  • QLogic CNA 8324/8362 适配器
  • Dell EMC S5296F-ON (SmartFabric OS10)

问题

  • 在核心网络交换机迁移期间,AFF-A300 集群的两个控制器在其接口组内经历了所有物理网络接口(e0e、e0f、e0g、e0h)的严重且反复的抖动。
  • 端口间歇性地离开并重新加入接口组,导致连接中断和数据访问丢失。
  • 多个生产应用程序中断和损坏报告
  • 多个 SQL 集群仍处于降级状态,引发管理层对存储平台可靠性的担忧。
  • 事件发生期间,在受影响的端口上观察到 CRC 错误。
  • 该问题仅出现在 AFF-A300 系统上;其他 NetApp 系统(AFF-A800、FAS-8300)在连接到相同的新交换机时未出现类似问题。
