Conceptual Overview

Because there is no assurance of a kernel build environment being present on any given target system, the Open IPMI driver is shipped as compiled binaries. The source code is also included for GPL compliance. The hpmgmtbase installation matches the correct binary to the running kernel. If none match, warnings are printed and the system administrator will have to build binaries per the provided instructions. hpmgmtbase can be reconfigured to use customer-generated modules.

hpmgmtbase includes the following:

A set of binary drivers for multiple revisions of multiple distributions
Source code to those patched drivers for GPL compliance
Startup scripts (/etc/init.d/hpmgmtbase and helpers) to configure and load the correct driver and set up device file
hpbmc, a general-purpose tool to access the information maintained by the BMC. This includes
- Chassis identity (model number, serial number, and so on)
- Sensor Data Record Repository (SDRR, defined in IPMI), the material list of the BMC
- System Event Log (SEL, defined in IPMI), where the BMC stores low-level chassis events (sensor conditions, firmware events)
- Forward Progress Log (FPL, an HP extension) where the BMC stores informational events (similar to the POST log in x86 platforms)
- Current sensor readings
- CPU, DIMM, and PCI slot population
- Cell and partition assignments (midrange and high-end systems only)
- MP card information (IP address)
hpuid (named after a similar utility on Compaq Proliant hardware) — a utility that controls the Locator LED on a system.
hpseld — a utility to monitor the SEL for overflow and other critical events.
Shared libraries and lookup tables to support these tools and other HP products (such as SNMP agents and WBEM providers)
