适用场景

  • ONTAP 9
  • Brocade交换机
  • ESXi

问题描述

  • ESXi上报告IO错误。
  • C3 discard 主机连接的交换机端口报告错误。

portstatsshow 输出小数- 

er_rx_c3_timeout     20876         Class 3 receive frames discarded due to timeout
er_tx_c3_timeout     0           Class 3 transmit frames discarded due to timeout
er_unroutable       0           Frames that are unroutable
er_unreachable      0           Frame with unreachable destination
er_other_discard     20876         Other discards

  • 连接到主机的交换机端口上报告的Rx电源不在建议范围内

RX Power:   -10.7  dBm (84.6 uW)
TX Power:   -1.1   dBm (770.3 uW)

 

  • 按照以下步骤进一步隔离问题描述:
    • 将从服务器到交换机的缆线连接到空闲的交换机端口。
    • 如果新交换机端口出现问题、则故障组件 可能是服务器端SFP或缆线。
    • 首先更换服务器和交换机端口之间的缆线。
    • 如果服务器和交换机之间的POST电缆更换问题仍然存在,则继续执行解决方案。
