NDCTL-INJECT-SMART(1) ndctl Manual NDCTL-INJECT-SMART(1)

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

SYNOPSIS
       ndctl inject-smart  []

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  for the media temperature smart attribute.

       -M, media-temperature-threshold=
           Set  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  for the controller temperature smart attribute.

       -C, ctrl-temperature-threshold=
           Set  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  for the spares smart attribute.

       -S, spares-threshold=
           Set  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.
