I agree with the above and have stated to similar effect in my response
to Matt. A practical usage of ISID within an initiator node name space
is to assign it as unique across all targets, allowing the same ISID to
be used as a lookup key of the session for any given target port/node.

Not applying uniqueness in ISID assignment across all targets would then
require initiators to implement a second key mechanism for target
lookup.
