Bonjour,

 I'm not sure why it's saying (multiple).  But you notice it does that on
each separate login session.  Possibly Mike Christie will chime in with an
answer.   It isn't anything I would worry about.

Run this to see the existing sessions.

#iscsiadm -m session

e.g.  My environment is using MPIO and IPv4/IPv6 at same time.   You should
just see one entry per EQL volume.

And for more detail:

#iscsiadm -m session -P 1


 Out of curiosity, why don't you want to use MPIO, possibly getting better
performance and get redundancy as well?
