The 300G disk will be right-sized to the usable space of a 72G disk (68G?) and the extra space from the larger disk will be lost/unusable.

Do you have a shelf of 300G disks or were you just planning on buying a set of 300G disks to migrate into the shelf enclosure that the 72G disks are in?
If you have a shelf of 300G disks, attach it with a new loop and snapmirror or ndmpcopy migrate the data to the new shelf. Then detach the 72G shelf. Of course that is trickier with the 270's since the head IS a shelf.

Hi,
I have 'inherited' several filers including FAS 270's and FAS 940's which only have 72GB drives and we are now running very low on spares and the company I work for is reluctant to buy another shelf, it has therefore it has been proposed that we remove a disk at a time from a volumes raid group and replace it with a larger drive (300GB) and then once the raid has recovered then remove the next disk and repeat the procedure until all the disks in the volumes raid raid group have been replaced with larger ones.
My initial question is - is this possible and if so once all the drives in a particular raid group that makes up a volume have been replaced with larger ones will that show immediately as free space available in that volume or will we need to do something else to get the filer to see the additional free space?
Thanks
