Allen,
The method that I have used in the past which I believe works better than vol copy is the tar command:
mount both filesystems to your adminhost:
mount tornado:/vol/users /tornado/vol/users mount tempest:/vol/vol0/users /tempest/vol/vol0/users
cd to /tornado/vol/users and issue the tar command:
tar -cf - . | (cd /tempest/vol/vol0/users ; tar -xvpf -)
Doing this should also defrag the filesystems which I don't believe vol copy does...Someone can correct me here if I fell asleep during that part of the class.

Hi all,
I have an existing 740 (tornado) with two volumes - vol0 and users. I have a new 740 (tempest) with just vol0 and a qtree named "users". I want to copy all the user directories from torando:/vol/users to tempest:/vol/vol0/users in the easiest and quickest method possible. Both of the filers are connected via gig-ethernet to our main switch so using a filer-to-filer transfer would be the fastest.
Do any of you know if the "vol copy" command can be used in this case. Can I specify that the destination is actually a qtree?
The documentation for the vol command also says that the destination volume must be offline but that the root volume can't be taken offline. Is this a catch-22?
Thanks for the help!

Use this as long as you don't want to keep NT ACL's and attributes !-)
ndmpcopy is probably the best method (i've moved terabytes between filers using it). Especially as it's almost all filer-to-filer - the host you run the command on just controls the connections. Since it uses dump, it will save all the NT ACL's and file attributes.
