 According to the mapping spec, maximum power capability sensor is deprecated and
provided only for backward compatibility.
 The max value of Assigned Power Sensors for the Managed FRU slots shall not be set. HPI
users can check the Max value for the Assigned Power Sensor of the Managing FRU slots, to
determine the total power capability of that slot along with all slots being managed under
the same hardware address.
4.3 Working with the Multishelf Library
The multishelf HPI library allows your application to connect to and manage several shelves at
the same time. For this purpose the multishelf library provides several HPI controls which allow
the application to manage the connection to shelves and also to dynamically add and remove
shelves to the HPI environment. This section provides all the information that you need to
know in order to use these HPI controls and work with the HPI multishelf library.
4.3.1 Overview
HPI uses the concept of domains. Generally, a domain represents one shelf. Furthermore there
is a default domain. It acts as a container for all other domains and does itself not represent
actual hardware.
It is possible for multiple domains to represent the same physical shelf. This is for example the
case in typical AdvancedTCA systems which often provide two shelf managers with an HPI
daemon running on each of them.
