dmi_chassis_element

Synopsis

#include <opendmi/entity/chassis.h>

typedef struct dmi_chassis_element {
    dmi_type_id_t type;
    dmi_baseboard_type_t board_type;
    size_t minimum_count;
    size_t maximum_count;
} dmi_chassis_element_t;

Description

The dmi_chassis_element_t structure describes a kind of element a system enclosure contains, and how many of them it takes. The elements field of dmi_chassis_t is an array of them.

An element is named either by the type of the SMBIOS structures describing it, for example DMI_TYPE(power_supply) for power supplies, or by a baseboard type, for example DMI_BASEBOARD_TYPE_SERVER_BLADE for blades. One of type and board_type is set, and the other one holds the value telling that it is not used.

Fields

type

Type number of the SMBIOS structures describing the element, or DMI_TYPE_ID_INVALID if the element is named by board_type.

board_type

Baseboard type of the element, or DMI_BASEBOARD_TYPE_UNSPEC if the element is named by type.

minimum_count

Number of such elements the enclosure needs to work properly, 0 to 254, or SIZE_MAX if the data carries 255, a value the specification reserves.

maximum_count

Number of such elements the enclosure can hold, 1 to 255, or SIZE_MAX if the data carries 0, a value the specification reserves, which the library takes as no maximum.
