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=
           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict the operation to
           the specified bus(es). The keyword all can be specified to indicate the lack of any
           restriction, however this is the same as not supplying a --bus option at all.

       -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.
