适用场景

  • FAS2552
  • SFP-H10GB-CU3M 直连铜缆( DAC )
  • 光纤扩展器( FEX )
  • Cisco Nexus 5000 交换机

问题描述

  • 存储每小时报告以下消息:

vifmgr.cluscheck.crcerrors: Port on node is reporting a high number of observed hardware errors, possibly CRC errors.

  • 这一点也反映在 IFstat 命令的输出中:

Cluster::> system node run -node <node name> -command ifstat

-- interface e0d (18 days, 14 hours, 50 minutes, 56 seconds) --

  • 将缆线从 FEX 移至 Nexus 交换机时,问题描述仍存在。
  • 将缆线从同一个 Nexus 交换机移动到另一个存储端端口时,问题描述将遵循以下说明。
