Entity Paths

Entities represent the physical components in the system. Each entity has a unique identifier called an entity path. The entity path is defined by the component's location in the physical containment hierarchy of the system. An entity path consists of a series of {entity type, entity location} pairs, starting from the entity and ending at the root of the system hierarchy.

For example, the entity path of a blade in slot 4 of an ATCA chassis at position 3 would be:

{SAHPI_ENT_SBC_BLADE,1},
{SAHPI_ENT_PHYSICAL_SLOT,4},
{SAHPI_ENT_ADVANCEDTCA_CHASSIS, 3},
{SAHPI_ENT_ROOT, 0}

TABLE A-1 contains an abbreviated example of the resource table for a Sun Netra CT900 server. In this example, the system contains two ShMM 500 shelf managers, two CP3140 switch blades (slots 7 and 8), one CP3010 blade (slot 3), one CP3020 blade (slot 14), and one CP3060 blade (slot 12).
