TARGETS

183       -dimm [DimmIDs]
184           Restricts output to the sensors on specific PMem modules by
185           supplying the DIMM target and one or more comma separated PMem
186           module identifiers. The default is to display sensors for all
187           manageable PMem modules.
188

EXAMPLES

190       Gets all sensor information for all PMem modules.
191
192           ipmctl show -sensor
193
194       Shows the media temperature sensor for the specified PMem module.
195
196           ipmctl show -sensor MediaTemperature -dimm 0x0001
197

LIMITATIONS

199       In order to successfully execute this command:
200
201       •   The caller must have the appropriate privileges.
202
203       •   The specified PMem modules must be manageable by the host software.
204

RETURN DATA

206       This command displays a table with a row for each sensor on each PMem
207       module. Applying a specific PMem module or sensor type target limits
208       the number of rows. Applying options can be used to expand or restrict
209       the output.
210
211           Note
212           Supported thresholds for a given sensor are listed as a part of the
213           return data when using the -all or -display flag. Only the alarm
214           threshold is settable.
215
216       DimmID
217           (Default) The PMem module identifier
218
219       Type
220           (Default) The sensor type. Refer to the sensor table above.
221
222       CurrentValue
223           (Default) The current reading followed by the units of measurement
224           (e.g., 57 °C or 25%)
225
226       AlarmThreshold
227           The threshold value at which an alarm for the respective sensor
228           will be triggered.
229
230       AlarmEnabled
231           Current state of the alarm threshold, where applicable. One of:
232
233           •   0: Disabled
234
235           •   1: Enabled

237           •   N/A
238
239       ThrottlingStopThreshold
240           The threshold value at which firmware will stop throttling to
241           reduce overall thermals and keep the PMem module within safe
242           operating temperatures.
243
244       ThrottlingStartThreshold
245           The threshold value at which firmware will start throttling to
246           reduce overall thermals and keep the PMem module within safe
247           operating temperatures.
248
249       ShutdownThreshold
250           The threshold value at which device shutdown will occur.
251
252       MaxTemperature
253           The highest temperature reported in degrees Celsius for a given
254           media or controller sensor. This value is persistent through Power
255           Loss and is read-only.
