[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] spec revs to make TargetName reqd on every connectionJulian, Attached is an attempt to pull together all the required spec updates to make InitiatorName required on every login, TargetName required on every normal login, and clarify related text. Does this look good to everyone? Any places I missed? Andre Asselin IBM ServeRAID Software Development Research Triangle Park, NC Appendix D, TargetName option: Remove "LO" from Use. Change This key MUST be provided by the initiator of the TCP connection to the remote endpoint before the end of the login phase. The iSCSI Target Name specifies the worldwide unique name of the target. The TargetName key may also be returned by the "SendTargets" text request (and that is its only use when issued by a target). To This key must be provided by the initiator of the TCP connection to the remote endpoint in the first login request if the initiator is not establishing a discovery session. The iSCSI Target Name specifies the worldwide unique name of the target. The TargetName key may also be returned by the "SendTargets" text request (and that is its only use when issued by a target). Appendix D, InitiatorName option: Remove "LO" from Use. Change This key MUST be provided by the initiator of the TCP connection to the remote endpoint at the first Login of login phase for every connection. The Initiator key enables the initiator to identify itself to the remote endpoint. To This key must be provided by the initiator of the TCP connection to the remote endpoint at the first Login of login phase for every connection. The InitiatorName key enables the initiator to identify itself to the remote endpoint. The current version of the 6th paragraph in chapter 5 reads: The initial Login request of the first connection of a session (leading login) MUST include the InitiatorName key=value pair. The leading Login request MAY also include the SessionType key=value pair in which case if the SessionType is not "discovery" then the leading Login Request MUST also include the key=value pair TargetName. A suggested rewrite would be (building on the text suggested by Bob Russell): All initial Login requests MUST include the InitiatorName key=value pair. If the initial Login request is also a leading Login (TSID=0) and the new session is to be a discovery session, then the initial Login request MUST also include the SessionType=discovery key=value pair. If the initial Login request is a leading Login and the new session is to be a normal session, then the initial Login request MUST also include the TargetName key=value pair and MAY also include the SessionType=normal key=value pair. All initial Login requests that are not also a leading Login (TSID != 0) MUST include the TargetName key=value pair. Also, this text appears in 2.2.7: The initiator MUST present both its iSCSI Initiator Name and the iSCSI Target Name to which it wishes to connect in the first login request of a new session. The only exception is if a discovery session (see 2.4) is to be established; the iSCSI Initiator Name is still required, but the iSCSI Target Name may be ignored. The key "SessionType=discovery" is sent by the initiator at login to indicate a discovery session. A suggested rewrite would be: The initiator must present its iSCSI Initiator Name in the first login request. If the initiator is not establishing a discovery session (see 2.4), it also must present the iSCSI Target Name to which it wishes to connect in the first login request. The key "SessionType=discovery" is sent by the initiator on the Initial Login request to indicate a discovery session. See chapter 5 for a more detailed description of the Login process. Section 3.12.8 currently reads: The TSID is the target assigned component of the session identifier (SSID). Together with the ISID provided by the initiator, this uniquely identifies the session with that initiator. Suggested rewrite (melding current text w/John's rewrite): The TSID is the target assigned component of the session identifier (SSID). Together with the ISID provided by the initiator, this uniquely identifies a session from that specific target to that specific initiator. That is, the TSID is a unique value within the scope of a specific target (not necessarily unique within the iSCSI Target Network Entity).
