Does this always occur or does it only occur if you run the exact commands you listed above? Does the session ever get logged into properly (does the session state very show logged in)? Does this just happen with one session? If you can replicate it easily can you dun iscsid by hand with debugging on: iscsid -d 8 -f iscsiadm -m node -L automatic iscsiadm -m node -U all Send all the outpout from iscsid for both the login and logout command. -- You received this message because you are subscribed to the Google Groups open-iscsi group.
