ndmpcopy Connection setup for transfer failed

Hi,
I'm trying to copy a volume between two different Ontap systems with ndmpcopy command but it fails with the error "Connection setup for transfer failed" with no more details.

clusterA::*> node run -node clusterA_1 ndmpcopy -d -sa ndmp:passwordA -da ndmp:passwordB 192.168.1.10:/svm_A/test_vol 192.168.2.46:/svm_B/test_vol
Ndmpcopy: Starting copy [ 22 ] ...
Ndmpcopy: 192.168.1.10: Notify: Connection established
Ndmpcopy: 192.168.2.46: Notify: Connection established
Ndmpcopy: 192.168.1.10: Connect: Authentication successful
Ndmpcopy: 192.168.2.46: Connect: Authentication successful
Ndmpcopy: 192.168.1.10: Log: Session identifier: 18428
Ndmpcopy: 192.168.2.46: Log: Session identifier: 70732
Ndmpcopy: Connection setup for transfer failed
Ndmpcopy: Done

Can the reason be a firewall issue between both systems ? Is there any way to have more details ?

Thanks for your help

David

Hi @Sergey_Osipov ,
thanks for the reply, but I finally resolve my issue.
The destionation LIF was not on the same node than the volume.

After migrating the LIF, it's working find.
Problem resolved.
