254 Implementing an Open IBM SAN
By implementing two zones, we limit the access of a particular host FC port to
only one ESS FC port. We do this because we like to have only two paths to a
ESS logical volume.
These two paths are created by giving the two host FC ports of one server
access to the particular ESS logical volume using ESS LUN masking.
In Figure 3-67 we show how these ports are physically attached to the INRANGE
director.
