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.

No, it is not. Aggregate space is linked to the raidgroups that exist within the aggregate, limiting an aggregate to physical disks. Also, you cannot remove disks from an aggregate without destroying the aggregate completely.
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.

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?

You can use snapmirror to migrate the volume to a new aggregate. When you are ready to make the final cutover, rename the original volume then rename the new volume to match the original volume name. You will also need to move your CIFS shares (if you have any). Then you can grow the new volume to the size you need. This will be a minimal disruption to users and transparent as far as their applications, etc are concerned.

With LUN data, you may want to talk to your NetApp account team about NetApp's ReplicatorX software. This should be able to do what you want.

Hello,
Would ReplicatorX allow us to move individual LUN's to another volume within the filer with no or minimal downtime?
If not is there any other way we can move a few of the LUN's on our FC based storage to our SATA based storage with minimal or no downtime?
I am sorry my question was not as clear as it could have been the first time.
Thanks again.
I'm not a RepX expert, but as I understand it (admitadly at 10000 feet) you install RepX on the host and it can move LUN data from one place to another, where "place" can be a given filer, a different filer, or even someone else's storage. This can be done with minimal to no downtime (probably depending on the situation). Your account team can pull in a RepX expert to give you the gory details. In the mean time, here's a link to the marketing stuff if that's helpful.

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.

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.

We are running an application called QAD that runs one of our manufacturing plants. According to our pSeries administrator it can only run on RAID1, does anyone have information about this? I am dubious but want to be certain.
It's on a pSeries that would be FC connected to the filer.

I would be shocked, *shocked*, to find out that the application technically requires RAID-1. More likely, the vendor has specified that they "recommend RAID-1", and the admin has taken it as gospel.

i would love to see how the application determines what level of RAID if any was on the mountpoint it was installed on. :)
it's similar to oracle dba's who ask how many physical drives are on each mountpoint even after you explain the concept of aggregates and flexvols 500 times...
give him a mountpoint/lun and tell him it's RAID1.

Heh, does the application also have a preference over disk manufacturer?
I seriously *highly* doubt an application has that much insight into the RAID config of the disk volume it accesses. All of that is masked by the storage controller that presents the storage to the host.
I could easily be very wrong, so I'd be very interested if there is merit to their claim.

We are running an application called QAD that runs one of our manufacturing plants. According to our pSeries administrator it can only run on RAID1, does anyone have information about this? I am dubious but want to be certain.
It's on a pSeries that would be FC connected to the filer.

Hi Jeremy,
That is because QAD stores its data in the Progress database, which is VERY I/O write intensive because of the Progress before- and after-image logs. That is why they do not want RAID5 as it sucks with high I/O writes. You may give them RAID4 or RAID_DP without problems - trust me. I have been involved in quite a few of the QAD implementations before.
The AIX admin is also still under misconception regarding the above - just correct him as well please. :-)
Kind regards,
