Thanks, but I cannot access this document. Can you please post the content of this KB ? Looks like it is an Internal KB. I just need to know the switches.

Thanks,

Procedure

Perform the following steps:

Enable NDMP. For more information, see the following article:
Enter node shell on the cluster:

::> node run local

Run the following command to dump to null:

filer*> ndmpcopy -sa root:<root-password> -da root:<root-password> -st text -dt text -e "DUMP_TO_NULL=y" <source-address>:/<SVM>/<volume> <dest-address>:/<SVM>/<path>

(Note: root user password may differ on source and destination)
