TSIH (Target Session Identifying Handle) is missing?

Hello, I wonder to know about the commentary at https://github.com/sebastiangraf/jSCSI/blob/master/bundles/target/src/main/java/org/jscsi/target/TargetServer.java#L232 It says about TSIH that should be implemented at the future. I would like to help to implement it based at http://www.ietf.org/rfc/rfc3720.txt:

• TSIH (Target Session Identifying Handle): A target assigned tag for a session with a specific named initiator. The target generates it during session establishment. Its internal format and content are not defined by this protocol, except for the value 0 that is reserved and used by the initiator to indicate a new session. It is given to the target during additional connection establishment for the same session. Based on the RFC 3720 I should get the session IDs and build these actions:

+------------------------------------------------------------------+ |ISID | TSIH | CID | Target action | +------------------------------------------------------------------+ |new | non-zero | any | fail the login | +------------------------------------------------------------------+ |new | zero | any | instantiate a new session | +------------------------------------------------------------------+ |existing | zero | any | do session reinstatement | +------------------------------------------------------------------+ |existing | non-zero | new | add a new connection to | +------------------------------------------------------------------+ |existing | non-zero |existing| do connection reinstatement| +------------------------------------------------------------------+ |existing | non-zero | any | fail the login | +------------------------------------------------------------------+

Looks like the TargetSession has the ISID and TSIH but CID (ConnectionID) where is? Am I correct? Could you give me any advice? Like if I have to create new classes? Which methods? Thanks in advanced. Felipe

Hi, I have some thing I think is related to it. The original problem is that after 10 hours of my microsoft iscsi initiator connect to the jSCSI target, the initiator try to reconnect, maybe a connection reinstatement, and it can't. I think it is related to ERROR_RECOVERY_LEVEL https://github.com/sebastiangraf/jSCSI/blob/master/bundles/target/src/main/java/org/jscsi/target/settings/SessionSettingsNegotiator.java#L155 that is set to 0 (zero) at target and 2 (two) at microsoft iscsi initiator. Is that possible? Should I set both to zero?
