If I understand you correctly, I don't think you can do what you want to do. It sounds like you want a volume to have space allocated in multiple aggregates. That won't work. You could copy an entire volume into a new aggregate, but you can't have a flex vol span aggregates. At least not in ONTAP 7. ONTAP GX can do this, but that's a very different configuration and you'd need to work closely with your sales team to see if it's appropriate for your environment.

We currently have a fas 940 with the following config:
3x 144GB FC shelves all but 2 disks are in aggr1 which equates to approx 3.9TB useable space which is approx 5.7TB raw (excluding the 2 spares) containing 4 volumes
5x 72GB FC shelves with 8 assigned to aggr2 (60 spares) containing 1 volume
We would like to increase the size of aggr1 and therefore plan to repalce 2 of the 72GB shelves with 144Gb, 4 of which will be retained as spares, thus giving us an extra 3.4TB of raw space to add to aggr1. Looking at the system configuration guide for the fas940 it states that the max raw aggregate size is 8TB therefore this would take aggr1 over the limit.
Is it possible to create a new aggregate (aggr3) assign the new 144GB drives to it but assign the space to the volumes held on aggr1?
As it stands if we were to replace 2 shelves with 144GB drives and remove 1 72GB shelf we would have a max size (based on 5x 144GB and 2x 72GB shelves) of 12TB which takes us to the max raw capacity of this filer using FC-AL drives.
Thanks
