From df4da5cdfca05b37b366b9c69925b68586969c1c Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 31 Dec 2010 02:22:18 -0600 Subject: [SCSI] libiscsi: add more informative failure message during iscsi scsi eh This adds a more informative error code and message for the iscsi scsi eh session drop paths. This allows you to distinguish if the session was dropped due to a connection failure vs the iscsi layer dropping the session due to scsi eh failure processing.
