To catch up on what I've learned so far:
"vol move" is not a new feature, in fact it seems to be a little-used older feature intended more for block-level services. I've used it to successfully move a test vfiler to a different aggregate but only by stopping and destroying the vfiler, then removing the default exports for the root and data volumes from vfiler0, and then running vol move sequentially for the volumes. Then I used the vfiler create NAME -r /vol/vfiler_root_volume to recreate the vfiler (and then corrected the broken network settings).
Usable if necessary but I'm looking at this as a last-ditch option.
To tell the whole story, we have a new 3240 that we installed running 8.0.2. Before putting it into production we decided to upgrade to 8.1GA, and did so with no trouble. Now I'm trying to blow away the old aggregates so I can build new ones with more spindles. But we do have one volume in production use, a whopping 100GB of data, but containing binaries for some HPC processing that is a problem to interrupt for more than a few seconds. I need a graceful way to move that vfiler to one of the new aggregates so I can nuke the remaining older ones and finish carving out the disks optimally for 8.1.
We also need to finally get a grip on NetApp's management options. We run a badly outdated NOM server, primarily for metrics for customer viewing. We've used a lot of filerview and the CLI until now, as most of our filers are still running 7.x or in a few cases 8.0x. But with 8.1 (no filerview) in the house we need to get modern. I do have OnCommand System Manager 2.0 on my workstation.
Now I understand I need the NMC, which is part of the OnCommand Core. I've found the installer for the Core, which needs Windows Server (or Linux).
So am I looking at bringing up another "NOM" like server? I get the NM Console described below from a distribution point on that server? If so, I can live with that, but when I try to install the Core, I get asked for a license key. I've found multiple references to the Core being free. One tip on finding a license key on my NOW page. But if I search my NOM license page for ONCMD I get No Results Found.
I'd be grateful if anyone can point me toward a noob-level breakdown of NetApp's management tools in their present state including what is and isn’t included as stock. I have a similar request out to both our VAR and our NA contacts.
Hope to hear from you,

Subject: Re: DataMotion for Volumes in 8.1?
Randy,
have you tried using the Netapp Management Console (NMC) for this?
I've done a few dozen vFiler migrations using the NMC vFiler migration "wizard" -
it asks you for all the parameters you would otherwise need on the command line and is robust and reliable in my experience.
You get it from the "OnCommand Core Package", via:
I only had resort to a command line vfiler migrate for an offline migration for a special vfiler once.
I'm currently planning 32, 64 bit upgrades with data motion,
Good luck,
Fletcher.

Hello All,
Running 8.1GA on a 3240 and trying to move two vfilers from one aggregate
to another (both are 64 bit aggrs). Ultimately I just need to move the
root and data volumes for these vfilers.
Not finding a wealth of examples on the "vol move" command, not surprising
as this is a pretty new feature.
http://www.netapp.com/us/communities/tech-ontap/tot-data-motion-1102.html
NetApp's blurb says this can be done without interruption, but also talks
a lot about when to do the "cutover." They say the cutover can be
triggered manually or automatically. But I can't make the "vol move"
command do anything but return a usage blurb unless I include a "start"
switch.
Also, their website claims this can be done nondisruptively. But "vol move
start" keeps failing because I have CIFS and/or NFS running. In fact, if I
turn them both off it still complains that I have NFS exports configured
and that I need to remove them first.
Anyone have experience moving volumes from one aggr to another, hopefully
live?
