适用场景

  • 所有NetApp FAS   / AFF 硬件平台
  • 所有Data ONTAP版本

问题描述

  • EMS日志中将显示类似于以下内容的错误字符串:

NETAPP01: fct_tpd_thread_3: fcp.io.status:debug]: STIO Adapter:0e AEN 0x8048 (RECV_ERROR) MboxStatus1 0x1002 MboxStatus2 0xa1

  • 此外、主机可能会也可能不会在通过上述适配器上的LIF访问的LUN上显示I/O错误
  • 对于报告上述事件的节点提供的LUN/Volumes、主机会报告高延迟。
  • 需要执行以下检查以进一步隔离问题描述:
    • 在最近的完整或每周ASUP中检查FCP-ADAPTER.XML 、或者运行fcp adapter show -instance 以验证接收(RX)和传输(TX)激光功率值
    • 查看交换机端口以及连接到存储端口的Tx和Rx电源。
    • 如果所报告端口中的SFP的TX值比其他端口低得多(经验法则:小于50%)、请更换SFP
    • 如果所报告端口中的SFP的RX值比其他端口低得多(经验法则:小于50%)、请检查交换机端SFP的TX值
    • 如果对应交换机端口中的SFP的TX值比其他端口低得多、请更换SFP。
    • 要 进一步隔离问题描述、请将缆线移至另一个交换机端口并检查问题描述是否继续、这意味着它是需要进一步检查的缆线。
    • 如果SP Tx和Rx电源两端都正常、则需要进行电缆测试。
