No suitable storage found while trying to use Western Digital NAS

Hi I’m trying to use a Western Digital NAS WD PR4100 to move at an off of my HA Green. Share is mounted under my MAC O/S filer.

When I try to move the data disk I get No Suitable Storage Found. Can the data not be moved from the HA Green to the NAS because it’s not locally attached to the NAS? All permissions on the NAS are read/write and I’m trying to use as a CIFS Share.

Any Ideas?
