クラスタネットワークの停止が原因でノードがCLAMクォーラムのメンバーでありません
環境
- ONTAP 9
- NetAppから購入したBroadcom BES-53248スイッチ
問題
- いずれかのノードで CLAM パニックが発生します。
PANIC : Received PANIC packet from partner, receiving message is (Coredump and takeover initiated because Connectivity, Liveliness and Availability Monitor (CLAM) has determined this node is out of quorum.)- パニックノード（FAS8200）のクラスタポートは10Gの速度でBES-53248スイッチに接続します。FAS8700
- のFAS8700のクラスタポートは100Gの速度でBES-53248スイッチに接続します。
- 大規模
