ISCSI says "Session Doesn't Exist"

[Santhapur Naveen <naveens@amiindia.co.in>]

Hello all,

    I've a question about IScsi and any suggestions would be helpful

[Issue Summary]
If I add an ISCSI attempt and on the next reboot, a connection will be established in between the initiator and the target. Till now, it is fine. Now if I do an immediate reset with in 20 seconds, on the next boot, the initiator is trying to establish a session, but the target rejects saying "Session does not exist". If I reset after 20 seconds or so, the connection would have been established with the same login details.

To dive deeper, I've checked the RFC documentation on this and found the following information. But when I checked the wireshark capture, I found my TSIH is ZERO even for the immediate session. If I want to make my immediate session also into a successful one, what should I be doing? I'm aware that there's a function available IScsiSessionAbort(). Would it help me or provide your suggestions to get me going.
