psexec allows you to execute commands on remote windows servers and "inq -hba" will provide WWN. It's just a matter of putting this in a perl/vbscript and collect the info.

why not get them from the switch ?

If you have to get them from the host, look into using psexec and inq utility.

Thanks, but I don't have access to the switch.  Only the server side.

Just thought someone must have had to do this previously.

I'd still try to get access to the switches and run a SAN Health (Brocade tool that also works on Cisco SANs).

In Navisphere / Unisphere you can use the "connectivity status" or similar tools on other arrays.

On the servers themselves "inq" (or the full blown EMCGRAB) does the trick as well.

If the Windows hosts are already on your SAN then you can retrieve the hba wwns' from the masking database in your ECC6\ECC6.1 Server with this command.
