28.5. Troubleshooting

Some NVDIMMs support Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) interfaces for retrieving health information.

Note

On some systems, the acpi_ipmi driver must be loaded to retrieve health information using the following command:
# modprobe acpi_ipmi
To access the health information, use the following command:
# ndctl list --dimms --health --dimm=nmem0
