<br>
I have oVirt Engine Version: 3.5.6.2-1.el6 with three nodesrunning<br>
standard Centos 6.7 64bit.<br>
<br>
The main data storage storage is on OpenFiler iScsi volume.<br>
<br>
After rebooting the three nodes; the main data storage domain is down<br>
and all the three hosts are marked as "Non Operational"<br>
<br>
When I try to activate any host; I get the below error message:-<br>
<br>
"Host XXXXX cannot access the Storage Domain(s) <UNKNOWN> attached<br>
to the Data Center Default. Setting Host state to Non-Operational."<br>
<br>
<br>
I have attached the engine and vdsm log.<br>
<br>
Best Regards<br>
Fawzy Ibrahim<br>
