Cause
此問題已在 2025 年 8 月 14 日發佈的韌體版本 32.46.3048 中確認並已解決。
這是已知的 NVIDIA 問題。在 PCIe 網路初始化期間,裝置韌體會影響訓練程序,且從韌體版本 32.46.3048 開始,問題已解決。
韌體演算法已經過最佳化,可改善 PCIe 連結穩定性。已確認新出貨的 NVIDIA 卡已包含更新的韌體版本 32.46.3048 或更新版本。
Resolution
執行完整的電源週期,確認介面卡是否再次可偵測到。
- 如果故障的插卡在電源重新啟動後恢復:
將 BlueField-3 韌體更新至 v32.46.3048 或更新版本,並確保 BFB 映像與更新後的韌體對齊。您可以使用 NVIDIA DOCA 軟體框架下載適當的檔案:
