I am looking for iSCSI traffic to go through e0M interface. But, iSCSI client error out saying "Login I/O error, failed". On NetApp Filer console I see below error
"Mon Dec 16 03:26:31 GMT [bgl-ucsm-netapp-filer-A: iscsi.warning:warning]: ISCSI: network interface e0M disabled for use; discarding incoming connection from initiator IP addr 10.106.189.197"
I do understand that e0M should not be used for data traffic, but I am not looking for any performance here. I went through discussion https://communities.netapp.com/thread/17020. but I did not find any answer. My Data ONTAP version is 8.0.1 -7-mode. Any help appreciated.

A case where you have to check multiple places...you can disable from iscsi interface, or you can block with options (and disabled or blocked will prevent access). In this case e0b isn't allowed because of options even though in the interface show list since it is in the blocked list. But even though the management interface isn't blocked it isn't showing in the interface list as an available interface so it won't work. I wouldn't use e0M for any data though (no VLAN support, and if a 3200 it is 100Megabit)...and in most new installs we don't use e0M just to prevent any issues. Even for cDOT node management I prefer gigabit or 10 gigabit NIC or ifgrp for the lif.
