适用场景

ONTAP 9

问题解答

  • 总线超限是 一个字段ifstat <interface>
  • 总线溢出 会计算 适配器的接收FIFO (先进先出)缓冲区溢出和数据包被丢弃的次数
  • 当总线繁忙且适配器无法将数据传输到主机内存时、会发生此错误
  • 出现总线超限时的建议
    • 监控来自计算机或最终用户的访问问题报告
    • 如果有访问问题报告、 并且数据包跟踪分析 表明端口(作为发生原因)丢失、请    与网络团队讨论如何在存储器和交换机端口上启用L2流量控制
      • 注意:在文件管理器端口上启用流量控制并不意味着已在连接的交换机端口上启用流量控制
      • TR-4182 和 "流量控制最佳实践" 提供了以下建议
        • 在Data ONTAP集群中的集群网络端口上禁用流量控制。
        • 其余网络端口(提供数据、管理和集群间连接的端口)上的流量控制应配置为与环境其余部分中的设置匹配。 
    • 减少ONTAP中的工作负载
