環境

  • ONTAP 9
  • Link Aggregation Control Protocol(LACP)
  • インターフェイスグループ(ifgrp)

問題

  • LACPが有効なifgrpでアクティブでないインターフェイスまたは停止しているインターフェイスがあります。

cluster::> ifgrp show
node    ifgrp    ports       down-ports
------------------ ----- --------------- ----------
node1    a0a   e0a,e0b,e0c,e0d    e0c,e0d

  • 物理ポートのステータスは「稼働」です。

cluster::> net port show -node node1 -port e0c,e0d
Node: node1
                                                     Ignore
                          Speed(Mbps) Health   Health
Port    IPspace    Broadcast Domain Link MTU  Admin/Oper  Status   Status
--------- ------------ ---------------- ---- ---- ----------- -------- ------
e0c     Default    Default      up  1500  auto/1000  healthy  false
e0d     Default    Default      up  1500  auto/1000  healthy  false
2 entries were displayed.

  • ifconfig -v は、同じifgrpの異なるポートに複数のシステムIDがあることを示します。

例:

  • LACPピアが2つの異なる system IDs (AA-BB-CC-DD-EE-FFとFF-EE-DD-CC-BB-AA)を送信している
  • のifgrpにはインターフェイスが1つだけ残っています。 ACTIVE state

::> system node run -node <node> -command ifconfig -v
