This is completely supported. I would suggest putting loopback plugs on the unused ports. This was best practice on FAS900, but I'm not sure about FAS3000. The loopback plugs slightly improve takeover and reboot times by not having the filer wait for timeout on an open loop.

LC loopback is X6521-R6 http://now.netapp.com/eservice/partDetails.do?partNumber=X6521-R6&produc tId=60420&rohsCompliant=R6 I know it says FAS270 on there, but it is used on any LC connector where loopback is needed. You can even use it to test Ethernet ports, although there is no value in terminating unused Eth ports.

Enjoy!

We have a 3050c clustered pair where both filers have 4 shelves of 144G FC disks each. We want to add two shelves of 500G SATA drives to one filer. We are not allowed to mix FC and SATA on the same FC Loop, so the two new shelves must be on a separate loop. Since this is a CF configuration, we will connect these shelves to both filers. The filer that owns the shelves will connect using the "A" port of its adapter while the partner filer will use its "B" port. But since we are not adding any shelves to the partner filer, this leaves us with a vacant "B" port on the filer that owns the shelves and a vacant "A" port on the partner. Does anyone know if this is a problem?
