The "Login negotiation failed" message looks customized but is coming from iscsi_target_login_sess_out(), which is only called when a login fails. That's likely because the login is failing to read the ISCSI header (which is 48 bytes), as noted by the "rx_data return 0, expecting 48" message. So the login is failing at the initial ISCSI Header phase. Has something occurred, like systems or the target rebooting? -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
