获取网络结构信息时、FC链路关闭并显示错误超时

• ONTAP 9.1
• Fabric OS 8.2.2D (FOS)
• Fabric OS 9.0.1.c (FOS)

• 在FC交换机更换联机ONTAP节点LIF后、可能会发生PLOGI/FLOGI故障 
• 适配器端口状态错误：

::> fcp adapter show -node node-01 -adapter 3c
  (network fcp adapter show)

Error: show failed: Timeout while getting fabric information

• 分区信息不可用：

::> net fcp zone show -node node-01 -adapter 3c
  (network fcp zone show)

Warning: Unable to list entries for kernel on node "node-01": Fabric query operation timed out or was rejected.
Error: show failed: Fabric query operation timed out or was rejected

• ::> event log show 表示在(交换机和/或主机适配器)端口回弹之后发生PLOGI故障

DEBUG      scsitarget.slifct.wqeError: FC port 3c has a WQE processing failure of type SLI_ELS_REQ, command PLOGI, subtype x0, with status of 3 and an extended status x8 for NPIV port 0.

• 链路上存储SFP和交换机SFP的功率值 处于正常范围

• fos命令 # nsshow -r 用于指示 适用于此SIFs的： 
  • NPIV Unknown as Device Type
  • SCR: none /也用表示 0x00000000
  • 否 FC4s/FC4 Feature 条目
