Ok that seems right, but on my case I have 4connections per HBA total of
8per Lun
The info I got regarding zoning is that each HBA is connected/zoned to
only one Storage controller
So that would make 2connections per Lun
What I suspect is that the Fabric here is made of 4switchs and that
makes 4x plus. The SAN people just configured it with a generic "big"
fabric zoning just one connection. but Linux shoes 4. could this be the
reason?

If one connection goes to one switch, and that switch is connected to
two controllers on the storage, then you'll see two paths on that HBA in
your host. If you have two HBA's and second is connected to second
switch, which is also connected to two controllers of the stroage, then
you'll see 4 of them.
That is the situation in my company. It goes like this:
________Hitachi controller0
/
HOST----switch0
\
\_______Hitachi controller1
