Support for the iLO3 fence device has been added to the fence_ipmilan fence device in the following errata: http://rhn.redhat.com/errata/RHEA-2010-0876.html.

The iLO3 firmware should be a minimum of 1.15 as provided by HP.

On both cluster nodes, install the following OpenIPMI packages used for fencing:

$ yum install OpenIPMI OpenIPMI-tools

Stop and disable the 'acpid' daemon:

$ service acpid stop; chkconfig acpid off

Test ipmitool interaction with iLO3:

$ ipmitool -H <iloip> -I lanplus -U <ilousername> -P <ilopassword> chassis power status

The desired output is:

Chassis Power is on

Test that fencing is successful.  From node1 attempt to fence node2 as follows:

$ fencenode node2
