4.4.8 HPI Daemon Switchover Control
This HPI control handles the switchover between the active and deactivated HPI-B daemon.
The location (active/deactivated) of the HBI daemon cannot be controlled directly. Instead,
this HPI control can be used to initiate a switchover. After the switchover is completed, if
eventing is enabled for the active HPI-B daemon sensor, the HPI Implementation will send an
event with the Resource Id of the new Resource hosting the active HBP daemon.
Note that the initiation of a switchover is meaningful only when the state of the HPI daemon
redundancy sensor is SAHPI_ES_FULLY_REDUNDANT. If there is no standby HPI daemon
present, an attempt to initiate a switchover will return the error code
SA_ERR_HPI_INVALID_REQUEST.
