RE: use of ISID

[Eddy Quicksall <eddy_quicksall@ivivity.com>]

The new login I was talking about was when it is the same "initiator". The
client may do several login/logouts during its initialization. If it uses a
different ISID each time, each login will be a different "initiator".

True, but that's the point, isn't it? Initiator Name + ISID is the
initiator designator (the I in I_T nexus), and an initiator can only have
one connection to a given target via a given portal. So you shouldn't try
to make a new login that re-uses the ISID, if you already have an existing
session.

Take care,
