Loading WWN from file Hitachi Storage Navigator

Is anybody familiar with the Hitachi Storage Navigator tool?

We are in the process of building a large number of SAN connected
servers. Currently we collect the WWN numbers from servers using a
script and then make a printout from which a SAN person enters the WWN
numbers manually and assigns disks through the Hitachi Storage
Navigator tool. This process is very prone to errors and delays the
build schedule. My question is there some way to import the WWNs to
the Hitachi SAN system from a file instead of typing all (hundreds)
WWNs manually? Can this be done using the Storage Navigator or some
other tool. Ideally we would like to avoid buying a separate software
package for this.

I hope my explanation makes sense and I would greatly appreciate any
pointers. Ziba.
