适用场景

  • ONTAP FCP

问题描述

  • FC主机/客户端无法访问LUN、但其他主机可以访问
  • 具有访问权限的主机受性能问题的影响
  • Microsoft Hyper-V 系统日志报告事件ID 153
  • Microsoft Hyper-V设备管理器报告存储适配器HBA端口处于未知状态、并显示"This device is not f횰 正常"(此设备未正常工作)
  • ONTAP事件日志每隔几分钟报告一次 FC IO错误状态= 5 和 AEN 0x8048错误
  • ONTAP ASUP和监控显示FC端口SFP传输光功率下降一半
ONTAP事件日志示例:
Cluster::*> event log show -message-name *fcp*
