When one of the paths fails no fail-over occurs (waited for 15 minutes). The device appears in /dev/mapper/ I know that on open-iscsi initiator the fail-over does happen. 1. Are there any known problems that can cause fail-over not to happen in linux-iscsi? 2. Is there any way to get debug information in order to understand more in-depth what's going on? 3. How can I know what the timeouts are and how to change them? 4. If you need more specific information, please write what can help. Michael
