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 ?

 

Venlig hilsen / Kind regards
