适用场景

ONTAP

问题描述

  • 在维护 接管/ 交还 期间、会注意到 使用同一HBA 应用程序专用集成电路(ASIC)个端口未启动
  • 主机MPIO会使用同一ASIC上的FC目标端口检测到LUN的故障路径或丢失访问权限
  • 此外、还可以观察 到、同一HBA/ ASIC上的两个FC目标端口 在过去不可靠
    • 示例: 排除故障后、如果报告2b脱机、则2A自动重置始终会恢复联机一小段时间
  • 系统日志(EMS)中可能会显示STIO和适配器错误
  • 启动/关闭交换机端口不会更改ONTAP 目标端口状态、status-admin已启动 
  • 已检查更换交换机以及ONTAP SFP和FC缆线
示例:
Cluster::> network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended
vserver          lif                   status-oper status-extended      status-admin
---------------- --------------------- ----------- -------------------- ------------
svm1              Node_1_4c             down        LIF not initialized  up
svm1              Node_1_4d             down        LIF not initialized  up
Cluster::>network fcp adapter show
Node  Adapter  Est  Address Admin Status  Status
---- --------  ---- -------  --------     -------
