HP Management Base Installation and User's Guide (May 2009)

Improper Function
Almost all problems with HP Management Base are related to the version and loading of the
three kernel modules that make up the Open IPMI driver. Specifically, it is the System Interface
(SI) module that causes the problems.
SI Module NameDistributionsKernel
ipmi_kcs_drv.o
RHEL 2.1, SLES 82.4 (old)
ipmi_si_drv.o
RHEL 32.4 (recent)
ipmi_si.ko
RHEL 4, RHEL 5, SLES 9, SLES 10,
SLES 11
2.6
The other two modules are always named impi_msghandler and ipmi_devintf.
The SI module shipped with the distributions has been out of synchronization with HP Integrity
server hardware for most of its life. Sometimes the SI module does not load at all; in other cases
it loads but functions improperly.
Sometimes other user or system actions cause the distribution's drivers to be loaded before HP
Management Base is installed, which is incorrect. Use the following steps to remedy the situation:
1. Stop any HP IPMI programs that might be running:
# /etc/init.d/hpima stop
# /etc/init.d/hpwebm stop
# /etc/init.d/hpmgmtbase stop
2. Erase the current knowledge of appropriate IPMI drivers:
# /etc/init.d/hpmgmtbase unconfigure
3. Show any IPMI driver modules that may have been loaded before HP Management Base
was originally installed:
# lsmod | grep ipmi
4. For each of the modules listed above, rmmod ipmi_msghandler must be last. This removes
any offending IPMI modules.
5. Probe and select appropriate IPMI modules:
/etc/init.d/hpmgmtbase configure
If messages indicating you must rebuild your IPMI driver are displayed, see the
corresponding section of this document.
6. To cache the SDRR and start hpipmid:
# /etc/init.d/hpmgmtbase start
Wait 30 seconds, and then verify that hpipmid is running. If that works, then you must disable
whatever mechanism was loading the offending IPMI modules.
