It wouldn't be a matter of the number of disks in a shelf, but the raid group size and number of disks in the aggregate. Even if it would work, you would end up with wasted disk space as the largest aggregate you can have is 16TB. With 320GB disks, that would be roughly 56 disks, with 1TB disks, it would only be 16. So, if you have more than 16 disks in your current aggregate, you would exceed your max aggregate capacity after 16 1TB disks if the filer were to see them as 1TB disks.

Hi all,
We have a ton of shelves with 320gb sata in them. We'd like to replace them with 1tb satas, but we have no power to power new shelves, or much space for them for that matter.
I know that if I swap out one 320gb disk with a 1tb one, the netapp will only use 320gb of the 1tb disk. But if I did all 14, one at a time so it syncs, what happens after I change the 14th disk? Will the netapp still only use 320gb per disk, or will it realise it has a whole 1tb to play with?
