要验证 NVDIMM 是否运行状况良好并且您遇到了本知识库文章中所述的问题，请运行以下四个命令：
 

# 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"

这些命令是仅查询命令，应视为无中断。

处于此状态的节点的命令的输出应类似于：
 

# isi_hwmon -b NVDIMMHealthMonitoring
DIMM SLOT A7: OK

# isi_hwmon -b NVDIMMPersistence
NVDIMM Index 0

此处提供的输出是一个示例，您获得的输出中可能存在差异。重要部分是输出看起来类似，并且您不会收到错误消息而不是输出。

- 如果有任何通信问题/错误迹象，您必须继续对问题进行故障排除，并根据需要联系硬件 L2/SME 和/或 PowerEdge 支持团队。 

- 如果输出指示 NVDIMM 处于良好状态且没有问题，您可以使用以下命令手动清除 RO 状态：

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

应用纠正步骤后，请监视节点约 10 分钟，以确保它不会恢复到 RO 模式。如果节点重启或重新启动，则可能会再次出现此问题，并且可能需要重新应用此解决方法。PowerScale 工程部门已意识到此问题，并正在研究即将发布的 OneFS 9.1 版本中要实施的缓解步骤。同时，要永久解决此问题，您可以将群集升级到 OneFS 9.2 或更高版本。
