OpenHPI is an open source project created with the intent of providing an implementation of the SA Forum
's Hardware Platform Interface (HPI). HPI provides an abstracted interface to managing computer hardware, typically for chassis and rack based servers. HPI includes resource modeling; access to and control over sensor, control, watchdog, and inventory data associated with resources; abstracted System Event Log interfaces; hardware events and alerts; and a managed hotswap interface.
OpenHPI provides a modular mechanism for adding new hardware and device support easily. Many plugins exist in the OpenHPI source tree to provide access to various types of hardware. This includes, but is not limited to, IPMI based servers, Blade Center, and machines which export data via sysfs. For up to date status on these components, please check out the status page.
The OpenHPI project is always looking for more participants. If you are interested in using OpenHPI, or taking a part in the evolution of OpenHPI, please join our mailing list and drop us a line.

and the Changelog for 2.6.2
SNMP Subagent 2.3.4 has been released (09/13/06)
An updated OpenHPI SNMP Subagent, version 2.3.4, was released with a much needed update of the SAF
- MIB files have been updated to latest version available from the SAF
- Installation now also installs the needed mibs under $prefix/share/snmp/mibs
- Patched up to work with OpenHPI 2.6 latest stable.
PyOpenHPI - OpenHPI wrapper for Python programs! (9/1/2006)
Yes, you heard right. The OpenHPI team presents its python binding module. There is no official release for this yet, but you can get it from the subversion repository. Even though this is in beta state, the module already features all of the APIs made available through libopenhpi and the very handy libopenhpiutils.
We would very much like to know what people think of this python module. So check it out, take a look at and try the examples. Make sure you read the README file before you start as there is some good information about usage and system requirements for building the module. I think you'll be surprised by how well the APIs have been adapted to python, but you be the final judge on that.
Assuming you have subversion installed, type the following to checkout the PyOpenHPI python module:
svn co https://svn.sourceforge.net/svnroot/openhpi/python/trunk pyopenhpi
Enjoy and post your impressions on the mailing list
OpenHPI 2.6.0 has been released! (7/31/2006)
The 2.6.0 stable release is available on SourceForge (http://sourceforge.net/projects/openhpi). This version places the OpenHPI daemon as the standard way to get HPI data. The old non-daemon configuration is still available for debugging purposes, but you have to recompile the library with the right options, and it will not be the supported way for using OpenHPI.
Various features had been added to the 2.5.x development line for this release including:
- Blade Center Telco H support
- IPMI ATCA support
- Blade Center topology is now 'ATCA topology friendly'
- More blade sensors supported
- PowerPC support
- Unicode text buffer validation added
Highlights for 2.6.0 are:
- Persistence of Domain Alarm Table - Alarms are now persisted to disk per domain. This feature has to be enabled in openhpi.conf.
- Hotswap management enhancements - More plugin abi functions where added to give them a better control over insertion and extraction events.
- Daemon enhancements - The daemon is the standard way to use OpenHPI now. The advantage of the daemon is that you now have a default installation in which automatic discovery starts out much earlier regardless of any client connection. It also allows multiple connections to see the exact same HPI domain from different places in the network. Also, the daemon now logs to /var/log/messages for any error condition.
- Blade Center plugin improvements - Added blade bmc reset control and made blade operational sensors readable.

OpenHPI 2.5.2 released! (6/13/2006)
2.5.2 is out the door. A lot of clean up has been done in several areas to make the code nimbler and more bug-free. Note that for this release, threaded mode is always on. The option to choose otherwise has been eliminated. This is to prepare for a related change coming in 2.6.x concerning the integration of the standard core library into the daemon.
- Blade Center H support - Yes, support for the new blade center model is already in OpenHPI through the snmp_bc plugin.
- More blade sensors - snmp_bc has added code to detect additional sensors (see changelog for details).
- Client programs cleaned up - Obsolete programs deleted. hpiel was revamped and now accepts long-style options. The rest of the client programs will follow this trend in future releases.
- Fixed client library connection bug - Default timeout for connections to the daemon is now unlimited. Used to be 30 minutes unless you specified a different one when running openhpid.
- Code cleanup - Thanks to patches from the community, there where a couple of HPI conformance bugs fixed, better error checking added, and other build related issues ironed out.

OpenHPI 2.3.1 Development Release is out! (1/12/2006)
Happy New Year 2006! The OpenHPI Team welcomed the new year with a new 2.3.1 development release. Bugs have been fixed in the core library that came out of conformance testing. The Blade Center plugin went through some live testing where several bugs were found and fixed, along with added improvements. Here are the highlights:
- Blade Center plugin - now recognizes more types of events from the Management Module.
- Blade Center simulator - Along with more test cases, more types of resources were added in order to simulate the additional types of events.
- Better initialization - OpenHPI now initializes itself at linked time rather than waiting for the first session open. This is an advantage in threaded mode as it improves how quickly the resource presence table gets populated.

OpenHPI 2.3.0 Development Release is out! (11/19/2005)
After a long wait, the first development release since the latest stable version is finally out. The wait was worth it, though, as this release comes with many important fixes and improvements to both the library and plugins.
- C++ wrappers to SaHpi structures - an experimental set of wrappers has been created that enables coders to use SaHpi strucures using C++ syntax. Check it out under the top cpp directory in the source tree.
- saHpiEventGet Optimization - The code responsible for fetching HPI events has been tightened up and is now leaner, meaner, and quicker. Any delays to get existing events is reduced.
- Improved Blade Center plugin - Much better mappings of hardware have been added to this plugin
- IA64 cleanliness
- Client library improvement - sharing of session ids between threads is now possible (experimental).

Quality and Testing:
The OpenHPI team has worked very hard to achieve a high-quality implementation.
As noted above, the current bug count is very low and is primarily in platform support versus interface
implementation, feature support and/or specification conformance.
The current release was based on a criteria taking into account both conformance and functional aspects of the code.
Platform: Intel Carrier Grade TIGPR2U Server with IPMI 1.5 .
OpenHPI Plug-in: IPMI
OpenIPMI Version: 1.3.16 (latest)
Conformance results (hpitest):
Total test cases: 530
Pass: 341 (64%)
Fail: 3 (<1%)
N/A: 186 (35%)
Total test cases: 81
Pass: 51 (63%)
Fail: 0 (0%)
N/A: 186 (35%)
Changelog for 2.0.0
*Note: N/A means platform does not support tested features.
IPMI plug-in currently does not support Inventory write/add functionality due to lack of support in
current supported version of OpenIPMI (1.3.16). This will be resolved once we start using
OpenIPMI 1.4.x tree.
