Frank,

Do you have any special software options on the filers? NDMPCopy?
SnapMirror?

You can use volcopy I believe. This is how we moved our disk storage from
SCSI to fibre a while back. Also, ndmp copy, from ndmp.org works well.

Hi

I want to transfert all users data from a F85 to a F87
is there some command to "safely" do such transfert
I expect tar from a third remote machine would be very
slow to do the job.

The two filers are attached to the LAN with a gigabit
fiber link on the same switch.

Frank,

If the ndmp or snap utilities aren't available,
using multiple remote machines for the tar/cp will speed
things up. Mount source and target filers on each box,
and run cp commands for each subdirectory on the vol.
When I did this, I listed the subdirs, then split that
list by n boxes (12 I think it was) with a shell loop on
each one doing something like the below. Parallel tuning
applies, but it'd probably take more than a dozen cp on
different hosts to saturate the filer.

for f in `cat $list`
do
cd $source/$f
find . | cpio -dmpv $target/$f
done

Hello Frank,
If any of your filers is running Ontap 6.2 or above, then you should be able to use the 'ndmpcopy' command on the filer itself to make the copy. Ndmpcopy was designed specifically for such migrations, so it pretty much will work.

The other ndmpcopy from ndmp.org that Simon mentioned will also work, but you will require to install it on a solaris client machine within your network.

Hope that helps,
Amol.

Or if you don't have a solaris box at all, there is a java version of ndmpcopy
available at ftp://ftp.ndmp.org/pub/version.3/contrib/jndmpcopy.tar.gz
I used that perviously to move 12gb of data between filers and it worked
without a problem.

Ndmpcopy is in Data ontap? Excellent! It is a very easy to use tool, and
produces a very reliable copy. one point though - and I am sure you know
this - the byte count for your newly created directories will be different
from your originals. Not a great deal off, but if you df them you will some
differences (well we did)
