Hope this is enough of the log, no idea why it's saying invalid fence agents:

Hi Martin,

Sure is there a way to trigger the check (I cleared the alerts), or do I just need to have a poke around the engine log next time it happens?

Regards,
Brett

Hi,

I recently upgraded my testlab to oVirt 4.2-pre and have been having some issues.

One of which is fencing with Dell Drac 8 remote access cards.
The configuration I'm using works fine on my other (4.1.6) cluster...

Error:
Health check on Host host.example.com indicates that future attempts to Start this host using Power-Management are expected to fail.

Hi,

Could you please share engine.log around above message? We are executing get power management status call to check, so if this get PM status failed, the above error is raised.

Thanks

Martin

Fence agent setup for the host appears to be working though:

Which logs would be helpful in debugging this issue ?

Regards,
Brett
