I found the problem. Openfiler was connected two networks but iscsi
connections allowed only one of them. When I set both interfaces as
allowed, it worked.
My main iscsi storage is in a saperate network and connected with only
servers like you mentioned above. But this machine is backup purposes
only and connected to both servers and public network.
Meanwhile I decided to use NFS for VM backups and removed iscsi
connections from servers.
Thanks and regards.
