Adding Eli, that may want to give some input on this issue.

Subject: Re: [ovirt-users] Host remains Non-Responsive after reboot
I have done a bit more investigating on this matter. If I restart the node
from within oVirt using the power management option "restart", then the
node restarts and vdsmd DOES NOT start. If I go into the DRAC and issue
the command to power cycle the machine, then the machine restarts and vdsmd
DOES start. I can run the following command from another node in the
cluster:
fence_drac5 -a 192.168.200.105 -l root -p <password> -x -o reboot
and the node restarts and vdsmd DOES start.

Hi Rob,
Thanks for this report.
Would you please provide these logs, at the time frame, the host failure
occur:
1. oVirt Engine: /var/log/ovirt-engine/engine.log
2. host: /var/log/vdsm/vdsm.log
If it is reproducible, please add this info as well.
You can also check vdsm service status, on host, while host reported as
Non responsive,
by running on host 'service vdsmd status'
There might some problem, that might have prevented from vdsm service to
come up, on host.

Subject: [ovirt-users] Host remains Non-Responsive after reboot
I am running oVirt Engine Version 3.5.0.1-1.el6. I have 4 hosts in the
cluster. Each host has a drac5 and it is configured and working. I am
trying to simulate a node failure. I am running one HA VM on one of the
hosts for testing. I simulate the failure by powering off the host with the
VM running.
Here is what is happening.
* Host is powered off
* ~4 minutes pass and the host is recognized as not responding
* Automatic fence runs and the VM migrates. Another host in the node
is chosen as a proxy to execute Status command on the host.
* Same host is chosen as proxy to execute Start command on the host.
* Same host is chosen as proxy to execute Status command on the host.
* The host DOES physically start.
* The host never shows status of UP.
* I select “confirm host has been rebooted” and I see a manual fence
start.
* Host stays non-responsive.
* I put the host in maintenance and then activate it.
* Host still non-responsive
* I put the host in maintenance and do a reinstall
* Reinstall finishes and host becomes UP
So, everything seems to go fine with the HA functionality, but the host
never recovers without being reinstalled. Please let me know which logs you
need to look at to help me out with this.
Thanks
