Unless specified otherwise, it will use your Operating System's Default Route Interface for the network you are trying to discover to. What does your routing table look like? Also, the README shipped with the open-iscsi package talks about Offload configuration in section 5.1.2. To quote it... 5.1.2 Setting up a iface for a iSCSI offload card ================================================= This section describes how to setup ifaces for use with Chelsio, Broadcom and QLogic cards. By default, iscsiadm will create a iface for each Broadcom, QLogic and Chelsio port. The iface name will be of the form: $transport/driver_name.$MAC_ADDRESS Running: # iscsiadm -m iface default tcp,<empty>,<empty>,<empty>,<empty> iser iser,<empty>,<empty>,<empty>,<empty> cxgb3i.00:07:43:05:97:07 cxgb3i,00:07:43:05:97:07,<empty>,<empty>,<empty> qla4xxx.00:0e:1e:04:8b:2e qla4xxx,00:0e:1e:04:8b:2e,<empty>,<empty>,<empty> Will report iface configurations that are setup in /etc/iscsi/ifaces. The format is: iface_name transport_name,hwaddress,ipaddress,net_ifacename,initiatorname iface_name: name of iface transport_name: name of driver hwaddress: MAC address ipaddress: IP address to use for this port net_iface_name: Net_ifacename will be <empty> because change between reboots. It is used for software iSCSI's vlan or alias binding. Now, you could relate it to what you have, and see if your settings are complete. But please do share your routing table too. > > > But no information about connecting to target.

Maybe I might package it, but like I said, without access to hardware, I will not be doing a good job in maintaining its quality. -- Ritesh Raj Sarraf RESEARCHUT - http://www.researchut.com "Necessity is the mother of invention."
