  • AFF A400
  • 修正不能なマシンチェックエラー

問題

PCI分析ツールによって呼び出されたスロット3のNICを交換した後、ノードで新しいUncorrectable Machine Check Error(修正不可能なマシンチェックエラー)が発生しました。

  • NICを2回交換しても問題が解決しない
  • 最初のパニックは、ツールによってスロット3を呼び出しました。

Uncorrectable Machine Check Error at CPU18. SKL_IIO Error: STATUS<0xbb80000000000e0b>(VALID,UC,EN,MISCV,PCC,S,AR,CORR_ERR_STATUS(0),CORR_ERR_CNT(0),MSCOD(0),MCACOD(0xe0b))MISC<0x00000000ae000000>(UCR_BUS_LOG(174),UCR_DEVICE_LOG(0),UCR_FUNCTION_LOG(0), UCR_SEGMENT_LOG(0))I

スロット3でNICを交換したあとにパニック状態になる:
