It is not supported hot. You can panic the filer if you are unlucky doing this hot. If DOT happens to be performing a CP write to disk when you are plugging the loop in a new port it will dump core. This happened to a customer & we did a root cause analysis with tech support to find this out.
On a not-busy FAS you have a 1-in-10 second chance this will happen each time you plug in a cable. So, you have to ask yourself, "do I feel lucky?"

I want to attach FC tape drives to this filer. My TGA told me that tape drives are not supported on the FC cards I have in slots 3/4, but that they are supported on the onboard adapters 0a -> 0d. My disk shelves are supported in slots 3/4 with the FC cards that are there now. So instead of buying new FC cards for slots 3/4, I was going to move the disk shelves there and use the onboard for the tape drives. Is there a bigger issue with that plan ... above from doing it hot or cold ? When I plugged the tape drive into the adapters in slots 3/4, it didn't work, I got:
[fci.adapter.error:warning]: Fibre Channel adapter driver encountered error "Failed to get connection type" on adapter 3a.
continuously on the console until I unplugged it. Same story for 3b, 4a, and 4b.
My TGA followed up with:
... those cards are for disk shelf storage, not tape drives. For tape drives you'll need a part number X2053A-R6. Not a X2055A.
This 3040 was bought 3 years ago now, so its hard to remember everything. But it was configured with those cards to eventually add FC tape drives. My thought was that the disks were meant to be on the expansion cards from the get go, and leave the onboard for tape drives...
So to make it short.. my goal is to attach FC tape drives to this filer.
Thanks, Paul

There are some risks involved, so lets start with the basic question. Why do you want to move the loops to the expansion cards in the first place?
