問題

両方のノードが同時に「シャーシファンFRU障害: 複数のファンが故障しました」と報告します。

HA Group Notification from Cluster-01 (CHASSIS FAN FRU FAILED: Multiple fans have failed) ERROR HA Group Notification from Cluster-02 (CHASSIS FAN FRU FAILED: Multiple fans have failed) ERROR

EMS エラーは複数のセンサーが利用できないことを示します:

[Cluster: env_mgr: callhome.c.fan.fru.fault:error]: Call home for CHASSIS FAN FRU FAILED: Multiple fans have failed

以下の試行では問題は解決されませんでした。アラートをクリアできません。

BIOSとBMCファームウェアを最新バージョンにアップグレードしました。
両ノードのBMCを再起動しました。
マザーボードを装着し直し、交換を試みました。新しいマザーボードを使用しても、装着後、すべてのノードが以下のエラーで起動できません。
