若要確認 NVDIMM 狀況良好，且您是否正在執行此 KB 中所述的問題，請執行下列四個命令：
 

# isi_hwmon -b NVDIMMHealthMonitoring
# isi_hwmon -b NVDIMMPersistence
# /opt/dell/DellPTAgent/tools/pta_call get agent/info
# /opt/dell/DellPTAgent/tools/pta_call post "host/sensordata?sensorSelector=iDRAC.Embedded.1%23SystemBoardNVDIMMBattery&sensorType=DellSensor"

這些命令僅為查詢命令，應視為不中斷。

此狀態下節點的命令輸出應類似：
 

# isi_hwmon -b NVDIMMHealthMonitoring
DIMM SLOT A7: OK

# isi_hwmon -b NVDIMMPersistence

此處提供的輸出為範例，您得到的輸出可能有所差異。重要零件是輸出看起來類似，而且您沒有收到錯誤訊息而非輸出。

- 如果有任何通訊問題/錯誤的指示，您必須繼續疑難排解問題，並視需要聯絡 HW L2/SME 及/或 PowerEdge 支援小組。 

- 如果輸出表示 NVDIMM 處於良好狀態且沒有問題，您可以使用下列命令手動清除 RO 狀態：

# /usr/bin/isi_hwtools/isi_read_only --unset=system-nvdimm-failed

套用修正步驟後，請監視節點約 10 分鐘，確保不會回到 RO 模式。如果節點已重新開機或重新開機，則可能會再次發生此問題，而且可能需要重新套用此因應措施。PowerScale 工程部門已察覺此問題，並正在調查即將于 OneFS 9.1 版中實施的緩解步驟。在此同時，若要永久解決此問題，您可以將叢集升級至 OneFS 9.2 或更新版本。
