That is weird. I have never seen it before for this type of setup. The iscsi tools are able to do tcp connections through the different iscsi faces and nics, but in this case the target is returning a error: ----------------------------------------------------------------- Out of | 0302 | The target has insufficient session, resources | | connection, or other resources. ----------------------------------------------------------------- You probably need to contact EMC to get info on its limitations or on how to set it up for this type of setup. When you only have one session connected, if you do iscsiadm -m node -T yourtarget -p ip -I iface_you_are_already_logged_in -o new does this login ok? If you do iscsiadm -m session -P 3 do you see 2 sessions? -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
