Hello Ting, I've configured iSCSI target in Windows Server 2012. And the procedure is similar as in https://blogs.technet.microsoft.com/filecab/2012/05/21/introduction-of-iscsi-target-in-windows-server-2012/ Please let me know if I had to make any changes to my iSCSI server.
Thank you, Naveen ________________________________________ From: Ye, Ting [ting...@intel.com] Sent: Monday, February 27, 2017 1:23 PM To: Santhapur Naveen; edk2-devel@lists.01.org Subject: RE: ISCSI says "Session Doesn't Exist" Hi Naveen, According to the table you shared (defined in RFC 3720), it seems when TSIH is ZERO, the target should not fail the login with "session does not exist". +------------------------------------------------------------------+ |new | zero | any | instantiate a new session | +------------------------------------------------------------------+ |existing | zero | any | do session reinstatement | | | | | (see section 5.3.5) | +------------------------------------------------------------------+ I checked the latest code in NetworkPkg/IScsiDxe, the Tsih is always set to ZERO in IScsiSessionInit. The immediate reset will also trigger driver binding start so IScsiSessionInit will be executed. It seems to me your iSCSI target does not comply with the rules defined in RFC documentation. If possible, would you please tell us which iSCSI target are you using? Thanks, Ting -----Original Message----- From: edk2-devel [mailto:edk2-devel-boun...@lists.01.org] On Behalf Of Santhapur Naveen Sent: Friday, February 24, 2017 9:59 PM To: edk2-devel@lists.01.org Subject: [edk2] ISCSI says "Session Doesn't Exist" 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. +------------------------------------------------------------------+ |ISID | TSIH | CID | Target action | +------------------------------------------------------------------+ |new | non-zero | any | fail the login | | | | | ("session does not exist") | +------------------------------------------------------------------+ |new | zero | any | instantiate a new session | +------------------------------------------------------------------+ |existing | zero | any | do session reinstatement | | | | | (see section 5.3.5) | +------------------------------------------------------------------+ |existing | non-zero | new | add a new connection to | | | existing | | the session | +------------------------------------------------------------------+ |existing | non-zero |existing| do connection reinstatement| | | existing | | (see section 5.3.4) | +------------------------------------------------------------------+ |existing | non-zero | any | fail the login | | | new | | ("session does not exist") | +------------------------------------------------------------------+ Thanks, Naveen _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
