Proper Function

In a properly functioning system the following should be observed:

No errors occur during installation of hpmgmtbase.
Three IPMI kernel modules are visible from lsmod.
An IPMI character device major number is visible from cat /proc/devices
The character device files /dev/ipmi0 and /dev/ipmidev/0 exist with the major number seen in the previous item.
hpseld is running as a daemon.
When run as root, hpbmc Summary runs to completion without error.
Any additional HP-supported programs (such as SNMP agents) run without any BMC or IPMI errors.

hpmgmtbase installation performs two major steps to determine the appropriate kernel modules. hpmgmtbase ships with a set of binary modules compiled for the known releases from the major vendors. The installation script examines the run-time environment and selects the correct module set.

However, if there is already a set of IPMI modules loaded from some other source (by other user actions), then hpmgmtbase assumes these are functioning properly, is properly reloaded at reboot, and takes no further action (by trying to use precompiled modules).

When hpmgmtbase is started using the following command, the following actions are taken:

# /etc/init.d/hpmgmtbase start

The module set designated by the installation process is loaded.
The major number allocated to the driver is used in the creation of the following device files:
/dev/ipmi0
/dev/ipmidev/0
These are well-known names in the Open IPMI community and are the defaults for hpbmc as well as open source programs such as ipmitool.
The BMC SDRR is read and cached in a file. This takes over 20 seconds on certain HP Integrity servers, but it speeds up all subsequent operations.
hpseld is started.
The hpmgmtbase script is linked into the appropriate /etc/rcX.d directories to ensure early start-up.
