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