Physical and Logical Properties

The Sun Management Center console presents hardware information for the supported platforms using a common set of tables and fields. This chapter provides a summary of the classes and properties by table.

The chapter contains the following sections:

System Properties

Physical Component Properties

Logical Device Properties

Environmental Sensor Properties

In the following tables, some fields can be filled with "--" or be blank in the following circumstances:

The table or field is not currently used.

For example, for many physical components a serial number is not available and therefore the Serial Number field of the corresponding table will contain "--". This is also the case with other common properties.

The field normally contains data under certain conditions.

For example, the Additional Info field contains textual information only when an alarm condition exists.

Logical Device Properties

Devices represent the logical devices. For example, a CPU module could contain one or more processors, hence the CPU module would be represented as a physical component, whereas the processors within it would be represented here as logical devices. The following tables enumerate the logical devices included in the common model.

FIGURE 3-2 Part of the Logical Device Table Showing Indicators (Sun Fire V250 Shown)

Logical devices introduce an Availability property. The Availability values are:

Other

Unknown

Running/Full Power

Warning

In Test

Not Applicable

Power Off

Off Line

Off Duty

Install Error

Power Save - Unknown

Power Save - Low Power Mode

Also introduced with logical devices is the Redundancy Status property. For devices that are part of a redundancy group, this indicates the current rôle played by this component. For example, a service processor may be operating in an active/standby pairing with another service processor. Similarly a network interface may be the primary or secondary member of a redundant network pair. Valid values for Redundancy Status are:

Not Applicable
