1つのNICポートで受信したCRCエラーがケーブル交換で解決
環境
- ONTAP 9
- FAS / AFFシステム
- 単一のデータポートでのCRCエラーレポート
- SFPおよび光ケーブルを使用するデータポート
問題
- イベントログでは、物理 ポートまたは論理ポートのハードウェアエラーが報告されます。
[node-01: vifmgr: vifmgr.cluscheck.crcerrors]: Port e0c on node node-01 is reporting a high number of observed hardware errors, possibly CRC errors
[node-02: vifmgr: vifmgr.cluscheck.crcerrors]: Port e0c on node node-02 is reporting a high number of observed hardware errors, possibly CRC errors
[node-02: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e0d on node node-02 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped)
ifstatONTAPがエラーを受信している場合は、出力にCRCエラーが表示されます。
