IPMCTL-CHANGE-SENSOR(1) ipmctl IPMCTL-CHANGE-SENSOR(1)

NAME

ipmctl-change-sensor - Changes the threshold or enabled state for PMem modules sensors

SYNOPSIS

ipmctl set [OPTIONS] -sensor (SENSORS) [TARGETS]
AlarmThreshold=(temperature) AlarmEnabled=(0|1)

DESCRIPTION

Changes the alarm threshold or enabled state for one or more PMem modules sensors. Use the command Show Sensor to view the current settings.

OPTIONS

-f, -force

Changing the sensor settings is a potentially destructive operation which requires confirmation from the user for each PMem module. This option suppresses the confirmation.

-h, -help

Displays help for the command.

-ddrt

Used to specify DDRT as the desired transport protocol for the current invocation of ipmctl.

-smbus

Used to specify SMBUS as the desired transport protocol for the current invocation of ipmctl.


Note

The -ddrt and -smbus options are mutually exclusive and may not be used together.

-o (text|nvmxml), -output (text|nvmxml)

Changes the output format. One of: "text" (default) or "nvmxml".

SENSORS

MediaTemperature

The PMem module media temperature in Celsius.

ControllerTemperature

The PMem module controller temperature in Celsius.

PercentageRemaining

Remaining PMem module’s life as a percentage value of factory expected life span.

TARGETS

-dimm [DimmIDs]

Update specified sensors on specific PMem modules by optionally supplying the PMem module target and one or more comma separated PMem module identifiers. The default is to update the specified sensors for all manageable PMem modules.

PROPERTIES

AlarmThreshold

The threshold value at which an alarm for the respective sensor will be triggered. The upper (for temperatures) or lower (for percentage remaining) alarm threshold of the sensor. Temperatures may be specified to a precision of 1 degree Celsius.

Table 1. Allowed AlarmThreshold

Sensor Allowed AlarmThreshold values Units
MediaTemperature 0-2047 Celsius
ControllerTemperature 0-2047 Celsius
PercentageRemaining 1-99 %

AlarmEnabled

Enable or disable the alarm threshold, where applicable. One of:

•"0": Disable

•"1": Enable

EXAMPLES

Changes the media temperature alarm threshold to 51C on the specified PMem module and enables the alarm.

ipmctl set -sensor MediaTemperature –dimm 0x0001 AlarmThreshold=51 AlarmEnabled=1

LIMITATIONS

In order to successfully execute this command:

•The caller must have the appropriate privileges.

•The specified PMem modules must be manageable by the host software.

RETURN DATA

For each PMem module, the CLI will indicate the status of the operation. If a failure occurs when modifying multiple PMem modules, the process will exit and not continue modifying the remaining PMem modules.

SAMPLE OUTPUT

Modify (Sensor) settings on DIMM (DimmID): Success
