NAME

       ndctl-inject-smart - perform smart threshold/injection operations on a DIMM

SYNOPSIS

       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.

       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

       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.

       --media-temperature-uninject
           Uninject any media temperature previously injected.

       -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.

       --ctrl-temperature-uninject
           Uninject any controller temperature previously injected.

       -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.

       --spares-uninject
           Uninject any spare percentage previously injected.

       -f, --fatal
           Set the flag to spoof fatal health status.

       --fatal-uninject
           Uninject the fatal health status flag.

       -U, --unsafe-shutdown
           Set the flag to spoof an unsafe shutdown on the next power down.

       --unsafe-shutdown-uninject
           Uninject the unsafe shutdown flag.

       -N, --uninject-all
           Uninject all possible smart fields/values irrespective of whether they have been
           previously injected or not.

       -v, --verbose
           Emit debug messages for the error injection process

       -u, --human
           Format numbers representing storage sizes, or offsets as human readable strings with
           units instead of the default machine-friendly raw-integer data. Convert other numeric
           fields into hexadecimal strings.
