适用于

  • ONTAP
  • 使用链路聚合控制协议 (LACP) 的接口组

问题

  • 在 ONTAP 升级期间重新启动存储节点,并且某些 LACP 成员处于关闭状态。

::> ifgrp show -fields down-ports,up-ports

  • 节点的网络端口已关闭并处于无链接状态。

::> network port show -node <node_name>

  • ​​​​​​从存储侧没有任何迹象表明存在任何链路抖动或从 Active IQ IFCONFIG-VVV 部分或 node run -node <node> ifconfig -v 测量的任何协商 LACP 的尝试:

a0a: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
lagg statistics:
active ports: 0
flapping: 0
laggport: e0a flags=20000<DEFAULT> state=41<ACTIVITY,DEFAULTED>
     input/output LACPDUs: 0 / 0
laggport: e2c flags=20000<DEFAULT> state=41<ACTIVITY,DEFAULTED>
     input/output LACPDUs: 0 / 0
status: no carrier

  • 对 Cisco 网络交换机进行调查,确定相应的交换机接口处于 Link Flap error-disable 状态。
  • Cisco 交换机日志记录显示重复的链路故障并禁用:

%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETH_PORT_CHANNEL-8-PORT_SUSPENDED: Ethernet1/1/2: Ethernet1/1/2 is suspended.
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_ERROR_DISABLED: Interface Ethernet1/1/2 is down (Error disabled. Reason:Too many link flaps)
