All right, I understand what are you trying to do... so does the NetApp support FC in order to connect a Tape backup now? (last time I saw this boxes was only SCSI for tapes, just couriosity)
Ok, I guess that a FC is possible now in the NetApp filer... does this HBA (in the filer) support fabric config? (I mean no FC-AL). If this support fabric, then you could connect the NetApp to the switch...
Will you connect the netapp to a tape library?
****************
There is no compatibility certification in EMC with NetApp filers and I think it will never be... ;o)
You could ask the compatibility matrix both McData and NetApp.

My guess: if you can configure the FC HBA in the NetApp as FC-SW then you are done!! you create the zone to connect the tape and done.
Cheers.
