Hi Martin
I see no firewall issues.
I have made some more tests :
RHEV 3.6 host khk9dsk30 test to khk9dsk34 & khk9dsk35 - OK
RHEV 3.6 host khk9dsk31 test to khk9dsk34 & khk9dsk35 - OK
RHEV 3.5 host khk9dsk32 test to khk9dsk34 & khk9dsk35 - OK
RHEV 3.5 host khk9dsk33 test to khk9dsk34 & khk9dsk35 – OK
OVIRT 4.01 host khk9dsk34 test to khk9dsk34 & khk9dsk35 – FAIL
OVIRT 4.01 host khk9dsk35 test to khk9dsk34 & khk9dsk35 – FAIL
OVIRT 4.01 host khk9dsk34 test to khk9dsk30 & khk9dsk31 – FAIL
Could you check in the code that ipmilan sends on port udp 623 ?
Yes, this is the default port
All hosts are on same VLAN
[root@khk9dsk31 ~]# fence_ipmilan -a khk9dsk35-mgnt.ip.tdk.dk -l mgntuser –p xxxxxxxx -o status
Status: ON
[root@khk9dsk31 ~]# fence_ipmilan -a khk9dsk34-mgnt.ip.tdk.dk -l mgntuser -p xxxxxxxx -o status
Status: ON
[root@khk9dsk35 ~]# fence_ipmilan -a khk9dsk33-mgnt.ip.tdk.dk -l mgntuser -p xxxxxxxx -o status
Failed: Unable to obtain correct plug status or plug is not available
[root@khk9dsk35 ~]# fence_ipmilan -a khk9dsk30-mgnt.ip.tdk.dk -l mgntuser -p xxxxxxxx -o status
Failed: Unable to obtain correct plug status or plug is not available

From the above I can say that there are some networking issues on host khk9dsk35, you said that firewall is OK, so are IPMI hostnames resolvable? Please also try to execute above with '-v' as we may get a bit more info about the issue.
[root@ khk9dsk35 ~]# fence_ipmilan -a khk9dsk35-mgnt.ip.tdk.dk -l mgntuser -p xxxxxxxx -o status
Failed: Unable to obtain correct plug status or plug is not available
This is normal, you are usually not able to connect to IPMI port of the host from the host Thanks Martin Perina Br,

Hi Martin
I was wondering if this could be a firewall problem. We have recently introduced new fw rules, and I have not tested fencing on the 2 hypervisors before I switched them to ovirt 4, but there was no alarm in the old setup before I switched. - I will investigate this further to be sure, and will return. Thanks for your help

Hmm, it's really strange that this is working on 3.6 and not on 4.0, I don't see any obvious error, so we need to find out what are correct parameters for your fencing device.
The easiest way is to execute fence_ipmilan, according to vdsm.log following are your current options:
fence_ipmilan -a khk9dsk35-mgnt.ip.tdk.dk -l mgntuser -p <PASSWORD> -o status
Does the above works if it's execute from khk9dsk34-mgnt.ip.tdk.dk? Btw is username correct? Shouldn't be there 'mgmtuser'?
If all of above is correct and you are still not able to get power status, here are options you could try:
-v
--lanplus -4

Hi,
Thank you for answering.
Here is the logs, one from each node.
I see the test from khk9dsk34 goes over khk9dsk35 and vice versa.
Same setup as on my redhat 3.6 setup, and no custom options.
Thanks
Peter

Hi Peter,
could you please share with us vdsm.log from the host that was used as fence proxy (the one that actually executed fence_ipmi agent)?
Also could you please check that fence agent options are the same as on 3.6 setup? Do you any any custom options for this specific agent?
Thanks
Martin

Hi
I’m testing on Ovirt 4.01 and got errors when testing fencing on the hosts
I use IBM x3550M4 as host and ipmilan as fence agent.
I get this error when testing.
[Failed: Unable to obtain correct plug status or plug is not available, , ]
I also have a 3.6 setup and there it works.
Ovirt Node 4.02
oVirt Engine Version: 4.0.1.1-1.el7.centos
Is this list the correct way to report errors ?
