Hi Kyle,

Below is the documentation from Ontap 6.3.1 - I would check you authentication {md5|text) - see below

Copying data with ndmpcopy What ndmpcopy is The ndmpcopy command calls a filer-resident data migration tool that controls the transfer of file system data between filers that support NDMP v3 or v4 and the UFS dump format. The ndmpcopy command supports both full and incremental data transfers; however, incremental transfers are limited to a maximum of two levels (one full and up to two incremental). The ndmpcopy command can transfer full or partial volumes, qtrees, or directories, but cannot be used to copy individual files.

ndmpcopy functions as a simple NDMP data management application (DMA) that performs data transfers by initiating a backup operation on the source filer and recovery operation on the destination filer. It establishes separate NDMP control connections with the source and destination filers, creates a single NDMP data connection between the filers, and initiates backup and recovery operations that result in the desired data transfer between the source and destination.

Because ndmpcopy is an NDMP application rather than an NDMP server, it can be executed at the command line of the source filer, the destination filer, or a filer that is neither the source nor the destination of the data transfer. It is also possible to execute ndmpcopy on a single filer that is both the source and the destination of the data transfer. See the ndmpcopy examples, next, for more information on supported data transfer topologies.

How to copy data using ndmpcopy To copy data within a filer or between filers using ndmpcopy, complete this step.

Note The command can also be entered from a filer that is not the source or the destination.

Step Action

1 Enter the following command:

ndmpcopy [options][source_filer:]source_path [destination_filer:]destination_path

options can be one or more of the following:

-sa username:[password]--Source authorization specifies the user name and password to be used when connecting to the source filer.

-da username:[password]--Destination authorization specifies the user name and password to be used when connecting to the destination filer.

-st {md5|text}--Sets the source authentication type to be used when connecting to the source filer.

-dt {md5|text}--Sets the destination authentication type to be used when connecting to the destination filer.

By default, md5 is the authentication type used. The text authentication type exchanges the user name and password over the network in clear text. The md5 authentication type exchanges the user name and password over the network in encrypted form.

-l level--Sets the dump level used for the transfer to the specified value of level. Valid values for level are 0, 1, and 2, where 0 indicates a full transfer and 1 or 2 an incremental transfer. The default level is 0.

-d--Enables generation of ndmpcopy debug log messages. ndmpcopy debug log files appear in the root volume /etc/log directory. The ndmpcopy debug log file names are in the form ndmpcopy.yyyymmdd.

-f -- Enables forced mode. This mode enables overwriting system files in the /etc directory on the root volume. See Example 5 for details.

-h--Prints the help message.

source_filer and destination_filer can be host names or IP addresses.

Examples of the ndmpcopy command In these examples, network host names are used for the filers. ("myhost" is used for a local filer and "remotehost1" and "remotehost2" are used for remote filers.) If you specify host names when you use the ndmpcopy command, the filer running the ndmpcopy command should be able to resolve these names to their IP addresses. In UNIX, you can use the ping command to make sure that host name resolution works.

Example 1: This command migrates data from a source path (source_path) to a different destination path (destination_path) on the same filer (myhost).

myhost> ndmpcopy -sa username:password -da username:password myhost:/vol/vol0/source_path myhost:/vol/vol0/destination_path

This shorter form of the command achieves the same purpose:

myhost> ndmpcopy /vol/vol0/source_path /vol/vol0/destination_path

Because you are running the ndmpcopy command on myhost and the source and destination filer are the same as myhost, you can omit the source and destination filer names on the ndmpcopy command line. When your ndmpcopy command is running on the same filer as the source filer or destination filer, you can also omit the -sa or -da options.

Example 2: This command migrates data from a source path (source_path) to a different destination path (destination_path) on remotehost1.

myhost> ndmpcopy -da username:password /vol/vol0/source_path remotehost1:/vol/vol0/destination_path

The destination filer must be specified in this case, because it is a remote filer. The destination authorization is needed, but not the source authorization.

Example 3: This command migrates data from a source path (source_path) on remotehost2 to a destination path (destination_path) on myhost.

myhost> ndmpcopy -sa username:password -st text remotehost2:/vol/vol0/source_path /vol/vol0/destination_path

The source authentication type specified by -st is text. The ndmpcopy command tool running on myhost will authenticate with the source filer using text authentication.

Example 4: This command migrates data from a source path (source_path) on remotehost1 to a destination path (destination_path) on remotehost2.

myhost> ndmpcopy -sa username:password -da username:password -l 1 remotehost1:/vol/vol0/source_path remotehost2:/vol/vol0/destination_path

The -l 1 option is used to do a level 1 transfer.

Example 5: Without the -f option, the /etc directory and its contents on the root volume of remotehost1 are protected from being overwritten with the /etc directory from myhost, preventing unintentional changing of the system characteristics after the root volume migration is completed.

myhost> ndmpcopy -da username:password /vol/rootvol remotehost1:/vol/rootvol

To overwrite intentionally the /etc directory during the root volume migration, use the -f flag as in the following copy.

myhost> ndmpopy -da username:password -f /vol/rootvol remotehost1:/vol/rootvol

I know that this isnt the correct forum to ask about ndmpcopy, but I do know that some use ndmpcopy with their filers. What I am trying to do is use ndmpcopy to copy a volume from a filer to a linux server running a ndmp server(ndmpsdk).

Info:

Linux 2.4.18smp kernel, ndmpcopy 1.2

NetApp filer Release 6.1R1

I run the ndmpcopy command correctly(I believe; usage is below), but on my filer console I get:

Wed Jan 29 13:33:22 EST [Java Thread:warning]: Ndmpd27: Top level IOException Wed Jan 29 13:33:22 EST [Java Thread:warning]: Ndmpd27: IO exception: Socket closed.

My usage:

ndmpcopy $filer:/vol/vol0 -sport 10000 $linux_server:/$path -dport 10000 -v -dpass

Has anyone use ndmpcopy successfully? Is my usage incorrect?

Thanks,

K.
