環境

  • ONTAP 9
  • NS224 シェルフ
  • スイッチ接続ストレージ

問題

  • システムが完全にサポートされている構成でケーブル接続されている場合に NoPathToNSMアラートを受信します。
  • 健全性アラートで複数のノードが報告されます
  • NSM AとNSM Bの両方が報告されます。
  • すべてのケーブルはプラットフォームに適したポートに接続されています。
  • スイッチへの物理的な接続に問題は見られません。
  • EMSログには、cshmを含むノードからのメッセージがスパムとして送信され、両方のNSMが呼び出されるため、ヘルス監視プロセスが抑制される可能性があります:
