4.5.7 Active and Stand-By HPI Daemon Sensor
The Artesyn HPI-B implementation provides two sensors which allow to detect which of the
two HPI daemons in a system is the currently active, and which is the currently deactivated
one. There are two sensors: one which represents the currently active HPI daemon, and one
which represents the currently deactivated daemon. Both sensors are Artesyn OEM sensors,
but the structure of their RDR is similar to the RDR of the standard Active and Standby Shelf
Manager sensors which are described in the HPI-to-AdvancedTCA mapping specification.
Both Sensors are logical Sensors which do not have counterparts in the IPMI or AdvancedTCA
realm. Applicable events and readings are generated by the HPI implementation.
Both Sensors are modeled as Presence Sensors.
