[ovirt-users] Problem about connecting iscsi server

I'm trying to setup oVirtManager on Centos 7. Here is the configurations: oVirtEngine Machine: Centos 7 minimal + GNOME multipath, firewall, iptables services are stopped and disabled. Host Machine: Centos 7 minmal VDSM is installed and working iscsi is installed and working multipath, firewall, iptables services are stopped and disabled. Situtation: oVirtEngine installed. DataCenter is set. Cluster is set. Host is set and active. I can see iqn of iscsi from oVirtEngine Machine via terminal. Like this: # iscsiadm -m discovery -t st -p 192.168.1.44:3260 192.168.1.44:3260,1 iqn.2016-01.vdsm.localhost:SCSI1 But I cannot connect same machine form oVirtManager. I get this error: No new devices were found. This may be due to either: incorrect multipath configuration on the Host or wrong address of the iscsi target or a failure to authenticate on the target device. Please consult your Storage Administrator. Thanx İren
