Platform-Specific Information

For related platform documentation, refer to “Supported Platforms” in the Sun SNMP Management Agent Release Notes.

The sunPlat Class Definitions

This section contains platform-specific information relating to class definitions and attributes.

Equipment

sunPlatEquipmentAdministrativeState

The sunPlatEquipmentAdministrativeState is read-only and reports unlocked(2).

sunPlatEquipmentUnknownStatus

For all slots, bays, and PCI cards, the precise operational state cannot be determined from available sensors or be derived from other components. Therefore, these all report sunPlatEquipmentUnknownStatus as true(1).

sunPlatEquipmentLocationName

For all objects this provides a string of the form:


serial number/hostname/NAC
Name

Where:

  • serial number is the serial number of the chassis, or blade serial number for the T6300, T6320, and T6340 platforms.

  • NAC Name provides a unique Network Access Control (NAC) name for each hardware component.

sunPlatEquipmentHolderPowered

Only read accesses are supported for this object.

Replaceable and Hot-Swappable Components

The following attributes are used to indicate a replaceable or hot-swappable component:

  • sunPlatCircuitPackReplaceable - A component is replaceable if it can be removed and replaced with a physically different component.

  • sunPlatCircuitPackHotSwappable - A component is hot-swappable if the power can be on when the component is removed or inserted. All hot-swappable components are replaceable.

  • isFRU - A component is a field-replaceable unit (FRU) if it is an identifiable part that can be obtained and replaced in the field.

Binary Sensors

Changes in binary sensors that result in sunPlatBinarySensorCurrent not taking the same value as that specified by sunPlatBinarySensorExpected generate an alarm with a sunPlatAlarmPerceivedSeverity of major(3). For example, when disconnecting a cable from a power supply on the Sun Fire V240 platform, an alarm is sent with a sunPlatAlarmPerceivedSeverity of major(3) and the value of sunPlatEquipmentAlarmStatus is set to major(2).

Numeric Sensors

The following table shows the mappings that exist between the configured threshold, the severity reported in the alarm (sunPlatAlarmPerceivedSeverity) and the severity (sunPlatEquipmentAlarmStatus) recorded against the related object for all numeric sensors.


TABLE 4-1   Numeric Sensor Mapping
Threshold sunPlatAlarmPerceivedSeverity sunPlatEquipmentAlarmStatus
lowerThresholdNonCritical(0) warning(5) warning(5)
upperThresholdNonCritical(1) warning(5) warning(5)
lowerThresholdCritical(2) major(3) major(2)
upperThresholdCritical(3) major(3) major(2)
lowerThresholdFatal(4) critical(2) critical(1)
upperThresholdFatal(5) critical(2) critical(1)

For numeric sensors, the following objects are not instrumented:


Note - sunPlatNumericSensorEnabledThresholds is read only.


Fan Tachometer Thresholds

The only threshold for fan tachometers configured is the lowerThresholdNonCritical(0). When the detected speed of the fan falls below the configured non-critical threshold, an alarm is raised and the sunPlatEquipmentAlarmStatus is assigned a severity of warning(5). As no further thresholds are set, no additional alarms are raised even if the speed of the fan drops further or stops.

Logical and Log Table Population

In the current version of the agent, the following tables are not used and are not populated:
