Migration from NetApp to VNX File
We are migrating a FAS250 to VNX5500 with multiprocol shares.
Issue 1.
We added the server_params.
server_param server_2 -facility cifs -modify acl.mappingErrorAction -value 3
server_param server_2 -facility cifs -modify acl.retryAuthSid -value 600
server_param server_2 -facility cifs -modify acl.FailOnSDRestoreError -value 0
From pervious posts, we have run LGDUP to copy the groups to the VNX.
lgdup.exe -v c:\lgdup.txt \\netapp \\vnxfile://\\new
When I run the following emcopy, I receive copious error messages, below.
C:\emc\CifsTools\emcopy\nt\emcopy64 \\netapp\share \\vnx\share /o /s /d /q /secfix /purge /stream /c /r:1 /w:1 /log:c:\emcopylog_share.txt
We are running this from a CMD prompt with elevated privledges (Domain Admin account), CTRL+SHIFT, right click on CMD shortcut.
Any assistance with resolving these error messages would be greatly appreciated.
Issue2.
There is a ~snapshot directory that is being copied for each file system, is there a way to exclude this from the copy?
====================
I have removed the file names and listed single instances of the messages.

what permissions do you have on the target ? (share and ACL)

Another way to exclude the ~snapshot directory is to hide it from the controller side.
ontap> vol options nosnapdir on
The directory will still exist, but will not show up when you scan for it.

Error 112 is a space reservation error (use net helpmsg XXX from a command prompt)
Could be sparse files or copying too many files at the same time (by default EMCopy uses 64 threads I think)
If there are local groups on the source (or local users) then look at the /lg and /lu switches
You can use the /xd switch to exclude directories (such as snapshots)

From Computer Mangement, the account is in the Administrators group.
From the Copy engine Statistics some of the files and directories have copied correctly, that is what is perplexing.

Thank you all for pointing me in the correct path.
The file system was full. The ~snapshot was consuming capacity, more than the actual file system. Once I was able to exclude that, the emcopy was able to complete successfully.

Spase file ?
Also remember that blocks on Netepp are 4k but 8k on Celerre

Very true, the file system is the same size as the original. So, the capacity should be ok. There are no quotas on this file system.

very odd error message (unable to reserve file space), there is plenty of capacity and not hard quotas that could be interfering ?
