Symptoms
- 在「iDRAC UI > 散熱」頁面中，將 iDRAC 韌體更新至 7.20.10.05 版後，平均速度會顯示介於 8% 到 100% 之間。
- 由於風扇速度增加，系統的噪音水準也會增加。
- 啟用偵錯選項時，您可以從 SupportAssist 記錄 （TSR） 中識別故障簽章。在 iDRAC 中
dumplogs一個NDC_ASIC觀察到感應器錯誤：
Cause
將 NDC 或 NIC 散熱屬性讀入 iDRAC 共用記憶體的時間間隔 （30 秒） 不足，導致 iDRAC 版本 7.20.10.05 中的風扇速度出現波動。
Resolution
此問題已在 iDRAC 版本 7.20.30.50 中修正，方法是將時間增加至 180 秒。
建議的因應措施是重設 iDRAC （racadm racreset 或從任何 iDRAC 介面進行一般重設），這可暫時解決此問題。伺服器冷開機或重新開機後會再次觀察到此情況。
