NAME

6       ndctl-inject-smart - perform smart threshold/injection operations on a
7       DIMM
8

SYNOPSIS

10       ndctl inject-smart <dimm> [<options>]
11

DESCRIPTION

13       A generic DIMM device object, named /dev/nmemX, is registered for each
14       memory device indicated in the ACPI NFIT table, or other platform
15       NVDIMM resource discovery mechanism.
16
17       ndctl-inject-smart can be used to set smart thresholds, and inject
18       smart attributes.
19

EXAMPLES

21       Set smart controller temperature and spares threshold for DIMM-0 to
22       32C, spares threshold to 8, and enable the spares alarm.
23
24           ndctl inject-smart --ctrl-temperature-threshold=32 --spares-threshold=8 --spares-alarm nmem0
25
26       Inject a media temperature value of 52 and fatal health status flag for
27       DIMM-0
28
29           ndctl inject-smart --media-temperature=52 --health=fatal nmem0
30

OPTIONS

32       -b, --bus=
33           A bus id number, or a provider string (e.g. "ACPI.NFIT"). Restrict
34           the operation to the specified bus(es). The keyword all can be
35           specified to indicate the lack of any restriction, however this is
36           the same as not supplying a --bus option at all.
37
38       -m, --media-temperature=
39           Inject <value> for the media temperature smart attribute.
40
41       -M, --media-temperature-threshold=
42           Set <value> for the smart media temperature threshold.
43
44       --media-temperature-alarm=
45           Enable or disable the smart media temperature alarm. Options are on
46           or off.
47
48       --media-temperature-uninject
49           Uninject any media temperature previously injected.
50
51       -c, --ctrl-temperature=
52           Inject <value> for the controller temperature smart attribute.
53
54       -C, --ctrl-temperature-threshold=
55           Set <value> for the smart controller temperature threshold.
56
57       --ctrl-temperature-alarm=
58           Enable or disable the smart controller temperature alarm. Options
59           are on or off.
60
61       --ctrl-temperature-uninject
62           Uninject any controller temperature previously injected.
63
64       -s, --spares=
65           Inject <value> for the spares smart attribute.
66
67       -S, --spares-threshold=
68           Set <value> for the smart spares threshold.
69
70       --spares-alarm=
71           Enable or disable the smart spares alarm. Options are on or off.
72
73       --spares-uninject
74           Uninject any spare percentage previously injected.
75
76       -f, --fatal
77           Set the flag to spoof fatal health status.
78
79       --fatal-uninject
80           Uninject the fatal health status flag.
81
82       -U, --unsafe-shutdown
83           Set the flag to spoof an unsafe shutdown on the next power down.
84
85       --unsafe-shutdown-uninject
86           Uninject the unsafe shutdown flag.
87
88       -N, --uninject-all
89           Uninject all possible smart fields/values irrespective of whether
90           they have been previously injected or not.
91
92       -v, --verbose
93           Emit debug messages for the error injection process
94
95       -u, --human
96           Format numbers representing storage sizes, or offsets as human
97           readable strings with units instead of the default machine-friendly
98           raw-integer data. Convert other numeric fields into hexadecimal
99           strings.
