Can you recompile the libiscsi module with debugging? uncomment this: /* #define DEBUG_SCSI */ in libiscsi.h You might also want to add some debugs in iscsi_eh_abort.

If the initiator dropped the session then you should see the conn error 1011 or a "target reset succeeded" or "host reset succeeded" message or a failure message if we did not log back in. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
