問題

一方のノードでCLAMパニックが発生した

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速度でBES-53248スイッチに接続します
FAS8700のノードのクラスタポートは、100G速度のBES-53248スイッチに接続します
vifmgr.cluscheck.ctdpktlossパニック発生前には大量のアラートが発生する可能性があります
