Hi again,

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.
