I have three machines; one manage and two hypervisors. I've configured power management for the two hypervisor nodes to use ipmilan as the power management type, with the options "power_wait=4,lanplus=yes". When I press the test button, the test fails. The error message on the manager is: 2012-04-12 10:48:54,610 INFO [org.ovirt.engine.core.bll.FencingExecutor] (http--0.0.0.0-8443-8) Executing <Status> Power Management command, Proxy Host:rhevh2.jfa.unibet.com, Agent:ipmilan, Target Host:, Management IP:10.0.102.150, User:root, Options:power_wait=4,lanplus=yes 2012-04-12 10:48:54,615 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-8) START, FenceVdsVDSCommand(vdsId = 242132ee-83ab-11e1-8e45-2c768aac9498, targetVdsId = cd224c12-83aa-11e1-a177-2c768aac9498, action = Status, ip = 10.0.102.150, port = , type = ipmilan, user = root, password = ******, options = 'power_wait=4,lanplus=yes '), log id: 643e7825 2012-04-12 10:48:56,824 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.FenceVdsVDSCommand] (http--0.0.0.0-8443-8) FINISH, FenceVdsVDSCommand, return: Test Failed, Host Status is: unknown. The fence-agent script reported the following error: Getting status of IPMI:10.0.102.150...Chassis power = Unknown On the proxy hypervisor, I get this message: Thread-48608::DEBUG::2012-04-12 10:58:32,009::API::954::vds::(fenceNode) fenceNode(addr=10.0.102.150,port=,agent=ipmilan,user=root,passwd=XXXX,action=status,secure=,options=) Thread-48608::DEBUG::2012-04-12 10:58:33,029::API::980::vds::(fenceNode) rc 1 in agent=fence_ipmilan ipaddr=10.0.102.150 login=root option=status passwd=XXXX out Getting status of IPMI:10.0.102.150...Chassis power = Unknown Failed err Thread-48610::DEBUG::2012-04-12 10:58:33,110::API::954::vds::(fenceNode) fenceNode(addr=10.0.102.150,port=,agent=ipmilan,user=root,passwd=XXXX,action=status,secure=,options=) Thread-48610::DEBUG::2012-04-12 10:58:34,129::API::980::vds::(fenceNode) rc 1 in agent=fence_ipmilan ipaddr=10.0.102.150 login=root option=status passwd=XXXX out Getting status of IPMI:10.0.102.150...Chassis power = Unknown Failed err It looks to me like the options are dropped, especially since the fenceNode line from the hypervisor says "options=". What's going on here? When I try to save the power management configuration, the Options-field is empty the next time I go to Edit Host. Running fence_ipmilan manually works fine, both from the hypervisors and the manager. I also can't find the "ovirt-manage-domains" command, so I'm starting to think this might be a problem with the CentOS build of oVirt I'm using ( http://www.dreyou.org/ovirt/).
