The HP Management Base scripts examine the running kernel version to assist in the selection of the appropriate binaries
for the HP-supplied Open IPMI modules. If the kernel version is changed,
the selection process will probably need to be executed again. This
situation might not be apparent until a reboot of the new kernel when hpmgmtbase fails to initialize or when other programs that
are dependent on the Open IPMI driver fail to start. A careful examination
of boot time logs can help to isolate this behavior.
This version change can happen because of a planned,
supported kernel upgrade (such as, an errata from Red Hat) or user-initiated
patching and rebuild. After the new kernel is installed, hpmgmtbase can be reconfigured to recognize the new version,
as follows:
Shut down any other products
and programs that rely on Open IPMI (such as, the HP Insight Manager
SNMP agents).
Stop HP Management Base:
# /etc/init.d/hpmgmtbase stop
Reconfigure HP Management
Base:
# /etc/init.d/hpmgmtbase reconfigure
Start HP Management Base:
# /etc/init.d/hpmgmtbase start
After a short time (up to 30 seconds) hpipmid should be running and hpbmc Summary should work (as outlined in the Chapter 4. If this fails, then the changes made
to the kernel may require a complete rebuild of the IPMI modules.
Remember that the source modules shipped with your distribution might
not actually work on your particular model of HP Integrity Server.
HP does not expect the source to be synchronized until RHEL4.4 or
SLES 10.
To fulfill GPL requirements, HP Management Base
includes the HP-modified source in /opt/hp/hpmgmtbase/OpenIPMI/src. These files are not patches but full source files for each of
the source components. To incorporate them into your new kernel,
the source files must be fully copied into your kernel source tree,
as follows:
Copy the appropriate source
files from /opt/hp/hpmgmtbase/src to ../drivers/char/ipmi in your kernel source tree.
For any 2.6 kernel, use
the source files under kernel 2.6.
For a 2.4 kernel and RHEL3,
use the source files under kernel2.4/K22. Red
Hat backported some of the 2.4.22 kernel source into their kernel,
even though it identifies itself as 2.4.21 base.
For other 2.4.21 kernels,
use the source files under kernel2.4/K21
Rebuild and install your
modules in the fashion appropriate for your kernel major/minor release
(2.4 is slightly different than 2.6).
Implement a mechanism
that loads your newly compiled modules at boot time (an /etc/init.d/rcX.d script) and runs before the HP Management
Base scripts.
Enter one of the following:
# modprobe ipmi_si (2.6 kernel)
or
# modprobe ipmi_si_drv
or
# ipmi_kcs_drv.
For all kernels, enter:
# modprobe ipmi_devintf .
Reconfigure HP Management
Base:
# /etc/init.d/hpmgmtbase
reconfigure.
The reconfiguration should recognize that modules
are loaded from some other source and ignore any HP-supplied binaries.
