[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] iSCSI: session login and ISIDThere seems to be a problem in distinguishing session logins, using only the ISID field in the Login Command. It is possible that different initiators could try to start a session using the same ISID value. One of those attempts will get rejected, since the ISID is the sole key to find if a session already exists. (note: TSID was sent as zero for the leading connection of session) The initiator WWUI does not seem to be available at this time. a) Appendix D.10 states that InitiatorWWUI is optional and defaults to iSCSI. b) Section 2.10.9 on Login Command states that "initiator MAY provide some basic parameters". On the other hand, Section 1.2.7 states that "the initiator MUST present both its initiator WWUI and target WWUI to which it wishes to connect during the login phase". The WWUI is also needed if we are to support multiple I_T nexuses between the same initiator and target. So it seems like Section 1.2.7 has the right spec. Appendix D and Section 2.10.9 must then be corrected. The descriptions in Sec 4.1 and Section 1.2.3 may also need to be changed to reflect the fact that initiator WWUI must be supplied at session login. -Sandeep
