适用场景

问题描述

  • 向Fabric Name Server Manager注册 的LIF不是 "NS Registration Done"(NS注册完成)、可能会出现超时或失败

net int show -vserver * -data-protocol fcp -fields status-oper,status-extended

  • 主机在重新启动后丢失LUN。
  • 主机配置有四条存储路径、但LUN只能通过一条路径查看。
  • 分区和配置遵循NetApp的建议、交换机和存储端端口的接收(Rx)和传输(Tx)速率均在最佳范围内。
  • 尽管FC端口在NetApp端显示为联机、但不会通过这些端口进行数据传输。

  • 在没有I/O操作的端口上、LUN不会通过这些端口在主机端可见。
  • 创建的新FC LIF未出现operational status up
  • 在 ONTAP上完成接管(到)/ Givback (GB)之前、主机无法连接到LUN
  • ONTAP升级后、LUN与主机断开连接
  • 重新启动主机不会解决问题描述问题
  • 启动程序 将报告 not logged in 状态

  • ONTAP上的多个适配器报告 超时 、导致与多个主机断开连接
示例:
cluster01::> network fcp adapter show -node node1 -adapter Xa
Error: show failed: Timeout while getting fabric information
cluster01::> network fcp adapter show -node node01 -adapter Xb
Error: show failed: Timeout while getting fabric information
  • MGWD.log 观察到的超时消息:

示例:[kern_mgwd:info:2548] 0x83771bf00: 0: ERR: SAN::FCP::ADAPTER_KERNEL: src/tables/san/fcp_adapter_internal.cc:get_imp:95 returning: 418/24 - Timeout while getting fabric information
[kern_mgwd:info:2548] 0x83771bf00: 0: ERR: SAN::FCP::ADAPTER: src/tables/san/fcp_adapter.cc:get_imp:719 returning: 418/24 - Timeout while getting fabric information

  • ONTAP中的停机/启动端口会暂时解析、但问题描述将在一两小时后返回
  • 无法解决交换机端的关闭/打开端口问题
  • 主机可能会记录类似以下内容的错误消息:

May 16 15:41:28 Host_name: qla2xxx [0000:b1:00.0]-5037:11: Async-login failed: handle=d pid=011703 wwpn=XX:XX:XX:XX:XX:XX:XX:XX comp_status=31 iop0=18 iop1=92900
