scp issue while copying the file from source to destination

I am trying to copy a file from the source server to destination server. Two scenarios bot failed. What could be the potential issue and how to diagonise?

1. [root@tensdnu1 stage]# scp –p -v /var/mmfs/ssl/stage/dave root@ttpkglu5.xxx.xxx:/var/mmfs/ssl/stage/dave
