Yes, just to be clear with everyone it was about moving the data from FC storage to SATA storage.
We have started this by doing a vol copy to move the LUN's that were offline from FC to SATA and we are going to look at ReplicatorX for the rest.
If anyone has any further suggestions please let me know :)
Take care.

This isn't really moving a volume. It's just publishing a different path name. The data stays right where it is. I believe the question was about physically moving the data from one aggregate to another.

I found this on earlier threads;
in exportsfs, you can export a path that uses a different backing store, via the "actual" option.
so, if you have a volume called (e.g.) "changeme", but you want users to see it as "newname", use:
/vol/newname/QTREE -actual=/vol/changeme/QTREE
According to this the volumes can be moved.

Is there any way this can be done that is fully transparent to the end users of the storage.
We have a similar situation and while we will be moving to GX in the long term this is not something that can be done in the short term and we are fast running out of space on our original aggr.
If a volume cannot be moved to another aggr without the end users noticing can a LUN be moved to another volume without end users noticing?
Kind regards,

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
