Swapping one size of disks for larger ones


We have a couple of DS14 shelves of 750GB SATA disks and we'd like to grow an aggregrate contained on them.

Is it possible (NetApp's selling policy willing!) to swap these 750GB disks for 1TB disks, one at a time, like you would say an HP server array and would you end up with more capacity at the end.

Just looking at cheaper alternatives to buying more shelves as these were purchased by a specfic dept not by general IT budget.



No, it is not possible.

What could be done – temporary loan shelf, install larger disks, copy data over (ndmpcopy, vol copy, SnapMirror – whatever is available) and then install disks back in original shelf. This obviously requires some downtime.
