Does it applicable for LUN copy? Or only volume level? I saw the manual for ndmpcopy and looks like it used to copy from different storage. What about vol copy? And if ndmp copy works, what is the correct step would be?
Yes, ndmpcopy can copy single file. It can be used within the same system or between two different systems. Vol copy copies the whole volume with all content. It can be used to copy single file.
ndmpcopy /vol/vol1/lun1 /vol/vol2/lun2
