環境

  • ONTAP 9.3以降
  • マルチモードLACP

問題

  • 物理ポートは稼働していますが、ifgrpは停止しています。

ifgrp down.png

  • 両方のポートをダウンしているifgrpの例:
Cluster::> network port ifgrp show
Port    Distribution              Active
Node   ifgrp   Function    MAC Address    Ports  Ports
------  -------  ------------ --------------   ------- ---------------
node0   a0a    ip       02:a0:98:11:22:33 none  e0c
  • LACPDUが増分しない

:このカウンタは ifconfig -v ONTAP 9.3で追加されました。

のしんだ

  • 2分待ってから再度実行し、LACPDUが増加しているかどうかを確認します。

  • 物理リンクの接続を確認しました。
  • ifgrpからポートを削除 しようとし、 [1] ifgrpがdownと表示されるポートを再追加しました。
  • 物理ポートの ステータスが同じまま切り替えられました。
  • 以下のリンク停止メッセージがEMSログに表示されます。
