Some ideas?

Actually, I'm not sure that IPMI will work with your hardware. Some of the HP machines come with "ILO MP", which does support IPMI. In that case, you would want to use IPMI to do fencing. I'm not familiar with your hardware, but I am guessing that you don't have ILO MP, and thus IPMI is not going to work.

Hi,

Do you have IPMI turned on in your kernel. It should be if you didn't recompile your kernel, but it not you can install that module. As far as recompiling your kernel, RedHat does not support that so you will have to download the vanilla kernel from kernel.org. This will be the source kernel. Once you have that I would open up a second screen and do a make menuconfig on the kernel that you do have installed under /usr/src/kernels/<kernel-version>. In the other screen install the source kernel with rpm -ivh <kernel src version>. Then build the kernel by going over to /usr/src/redhat/SPECS and doing rpmbuild -bp kernel<version>.spec. Below is a list of options:

-ba Build binary and source packages (after doing the %prep, %build, and %install stages).

       -bb    Build a binary package (after doing the %prep, %build,
and %install stages).

-bp Executes the "%prep" stage from the spec file. Normally this involves unpacking the sources and applying any patches.

       -bc    Do  the "%build" stage from the spec file (after doing
the %prep stage). This generally involves the equivalent of a "make".

-bi Do the "%install" stage from the spec file (after doing the %prep and %build stages). This generally involves the equivalent
              of a "make install".

-bl Do a "list check". The "%files" section from the spec file is macro expanded, and checks are made to verify that each file
              exists.
After that you need to make a symbolic link over in the
/usr/src/kernel/ directory linking back to your source directory of the kernel.(/usr/src/kernels/BUILD)

As far as with HP hardware, you can look on the disk. Or check this
link out:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lan
g=en&cc=us&mode=3&taskId=135&swItem=MTX-UNITY-I25296

I would go with the HP drivers . This should have came in hpasm
package. I have include the instructions from the hp site:

*Installation:*
Login as the system administrator (root), download the RPM to a directory on your hard drive and change to that directory.

If a previous version of the hp-OpenIPMI package has been installed, it must be removed before this package can be installed. To remove the previous version and any packages dependent on it, type the following:

      rpm -e hp-OpenIPMI

To install the package, type:

      rpm -ivh hp-OpenIPMI-< version >.rpm

The drivers will be installed to the /opt/hp/hp-OpenIPMI directory but not inserted. For HP ProLiant servers, the hpasm package will automatically load the hp-OpenIPMI drivers if required for a particular HP ProLiant server.

Additional information and help is available by typing either of the following:

      man hp-OpenIPMI

Additional information about features, installation, use, and troubleshooting the HP Server Management Drivers and Agents is available in the HOWTO documents available here: http://www.compaq.com/products/servers/linux/documentation.html.

Well hope this helps,
Tameika

Hi
We are having some problems to get fence working with this hardware.

Proliant 360 G5.. iLo firmware 1.42
and os is, RedHat 5-> 2.6.18-8.el5 Cluster/GFS

This script: fence_ilo
Fence shutdown works fine, but it don't restart it.
agent "fence_ilo" reports: failed to turn on

Have someone working script to get this work?
Enable IPMI on the iLO2 management card and use it instead.
