Thank you both Donald and Paul. That's it, i have 2 "ifaces" in my isci/ifaces: libvirt-iface-08bf216d libvirt-iface-33d9c275
I don't know how they appear there. deleting them and all my nodes config and rebooting, i am getting just one new: libvirt-iface-3e97ef13 discory seems to work fine now. login mount the resource just once, but i still see something about "multiple" mentionned while loggin in (see bellow) #iscsiadm -m node -T iqn.2001-05.com.equallogic:4-52aed6-65a51e6aa-5157080d44c5447a-slash -p 192.168.99.55:3260 --login Logging in to [iface: libvirt-iface-3e97ef13, target: iqn.2001-05.com.equallogic:4-52aed6-65a51e6aa-5157080d44c5447a-slash, portal: 192.168.99.55,3260] (multiple) Login to [iface: libvirt-iface-3e97ef13, target: iqn.2001-05.com.equallogic:4-52aed6-65a51e6aa-5157080d44c5447a-slash, portal: 192.168.99.55,3260] successful.
