| ===================== |
| |
| NAME |
| ---- |
| ndctl-inject-smart - perform smart threshold/injection operations on a DIMM |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'ndctl inject-smart' <dimm> [<options>] |
| |
| DESCRIPTION |
| ----------- |
| A generic DIMM device object, named /dev/nmemX, is registered for each |
| memory device indicated in the ACPI NFIT table, or other platform NVDIMM |
| resource discovery mechanism. |
| |
| ndctl-inject-smart can be used to set smart thresholds, and inject smart |
| attributes. |
| |
| EXAMPLES |
| -------- |
| |
| Set smart controller temperature and spares threshold for DIMM-0 to 32C, spares |
| threshold to 8, and enable the spares alarm. |
| [verse] |
| ndctl inject-smart --ctrl-temperature-threshold=32 --spares-threshold=8 --spares-alarm nmem0 |
| |
| Inject a media temperature value of 52 and fatal health status flag for DIMM-0 |
| [verse] |
| ndctl inject-smart --media-temperature=52 --health=fatal nmem0 |
| |
| |
| OPTIONS |
| ------- |
| -b:: |
| --bus=:: |
| Enforce that the operation only be carried on devices that are |
| attached to the given bus. Where 'bus' can be a provider name or a bus |
| id number. |
| |
| -m:: |
| --media-temperature=:: |
| Inject <value> for the media temperature smart attribute. |
| |
| -M:: |
| --media-temperature-threshold=:: |
| Set <value> for the smart media temperature threshold. |
| |
| --media-temperature-alarm=:: |
| Enable or disable the smart media temperature alarm. Options are |
| 'on' or 'off'. |
| |
| -c:: |
| --ctrl-temperature=:: |
| Inject <value> for the controller temperature smart attribute. |
| |
| -C:: |
| --ctrl-temperature-threshold=:: |
| Set <value> for the smart controller temperature threshold. |
| |
| --ctrl-temperature-alarm=:: |
| Enable or disable the smart controller temperature alarm. Options are |
| 'on' or 'off'. |
| |
| -s:: |
| --spares=:: |
| Inject <value> for the spares smart attribute. |
| |
| -S:: |
| --spares-threshold=:: |
| Set <value> for the smart spares threshold. |
| |
| --spares-alarm=:: |
| Enable or disable the smart spares alarm. Options are 'on' or 'off'. |
| |
| -H:: |
| --health=:: |
| Smart attribute for health status. Provide either 'fatal' or 'nominal' |
| to set the state of the attribute. |
| |
| -U:: |
| --unsafe-shutdown=:: |
| Set the flag to spoof an unsafe shutdown on the next power down. |
| |
| -v:: |
| --verbose:: |
| Emit debug messages for the error injection process |
