Re: iSCSI: multiple sessions b/n a pair of WWUIs.

John,

By the name-disc definition, an iSCSI initiator or target port is a
logical entity that constitutes the end points of a session.

Hence, there never can be 2 sessions b/n the *same* 2  initiator &
target port. Each session established spawns a *new* initiator and
target iSCSI port.

Going by the above semantics, there is always only 1 ISID/TSID per iSCSI
Initiator/Target port. 

Hence, I'm unable to understand your statements below.

As for the uniqueness of ISID across all initiators, is there any reason
not to allow implementations to do that ? I would have thought that is
the most typical use of an ISID and also allows initiators to lookup
their target structures based on ISID.

Regards,
Santosh
