Recommendations for adding new bigger disk shelves to existing system

Hey there,

I just got two new DS4243 450GB 15k SAS Shelves and am about to add them to our FAS3240HA. Right now, 4 DS4243 300GB 15k SAS disks are attached to this HA pair, 2 shelves for each controller.

Since 300GB disks cannot be purchased anymore, we got the 450GB shelves and I'm reluctant to just "throw away" about 5TB of usable SAS space by downsizing the 450GB disks to 300GB when adding them to the existing aggregates, or does this only apply to RAID groups? So if I create new RAID groups in the existing aggregates, will I then be able to use the "full" [0] size of the 450GB disks?

Thanks,

[0] After rightsizing and all other nice things NetApp does to the full capacity of the disks :)
