If you open Disk Management, and you right click on the Disk number on the right, hit properties, it should show the LUN ID. You also grab the iSCSI initiator or WWN at this time.
Then you can look on your filer to see which lun it is by running lun show -m, which will show the lun, the initiator, and the LUN ID.

Thanks for everyone's responses. We did the above and did not actually get the netapp WWN, but we got a port and target number that we were able to decipher from other LUN information. We have a CF pair each serving half of the LUNs. Fortunately, they were not set up identically and some of the LUNs with the same LUN ID were different sizes, which determined which filer was "target 0" and which was "target 2". We have a third filer on a completely different SAN and LUNs from that filer also come up with "target 0", but the port number is different because the Windows host accesses the other SAN with a different FC port.
Is there any "standard" Windows way (something to do with MPIO?) that maps the port and target numbers to, say, the filer's node WWN?
