openhpi - an implementation of the SA Forum’s Hardware Platform
OpenHPI is an implementation of the SA Forum’s Hardware Platform
Interface, which provides a standard C library interface to manage,
monitor, and control hardware (both local and remote).
OpenHPI 2.x implements the HPI B.01.01 specification.
The OpenHPI client library (libopenhpi) provides all the connection
functionality needed by the client application to connect to the
OpenHPI daemon running on the local or remote server.
Some of OpenHPI’s functioning can be changed by setting environment
variables. This documents all client environmental settings.
URL for the host running the daemon. This can be "localhost"
(default) if the daemon is running on the local host or an ip
The port number the host is listening on for clent connections.
Default port is 4743.
OpenHPI provides a number of plugins that talk to different hardware
types. The following is a list of tested plugins in OpenHPI 2.x.
An IPMI plugin that can talk locally (via smi interface and
OpenIPMI device driver) or remotely (via IPMI over LAN). It
supports IPMI 1.5 for standard rackmount servers, and some of IPMI
2.0 for support of ATCA chassis.
IPMI plugin depends on libOpenIPMI version 1.4.x.
An IPMI plugin designed specifically for ATCA chassis. It
implements IPMI commands directly in the plugin.
An SNMP based plugin that can communicate with IBM BladeCenter, as
well as IBM xSeries servers with RSA 1 adapters.
SNMP_BC plugin depends on net-snmp > 5.0.7.
