Re: [ovirt-users] Host cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center

Hi Fawzy, After you rebooted your 3 hosts you need to make sure you are confirming the hosts are actually rebooted. You can do it by right clicking on each host and select "confirm host has been rebooted" Thanks, Raz Tamir Red Hat Israel On Wed, Feb 10, 2016 at 8:50 PM, Fawzy Ibrahim <fawzy_ibrhim(a)yahoo.com <mailto:fawzy_ibrhim@yahoo.com>> wrote: Dear All; I have oVirt Engine Version: 3.5.6.2-1.el6 with three nodesrunning standard Centos 6.7 64bit. The main data storage storage is on OpenFiler iScsi volume. After rebooting the three nodes; the main data storage domain is down and all the three hosts are marked as "Non Operational" When I try to activate any host; I get the below error message:- "Host XXXXX cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center Default. Setting Host state to Non-Operational." I have attached the engine and vdsm log.
