Thanks for the reply Matt. I've been doing more digging and found a couple of article:
https://kb.netapp.com/app/answers/answer_view/a_id/1030813/loc/en_US
'...........the NetApp software can be negatively impacted if the file path name exceeds 255 characters on a Windows host operating system.'
And https://kb.netapp.com/app/answers/answer_view/a_id/1000976/loc/en_US
'On the storage system, the maximum length of a file name is 255 characters for NFS clients and CIFS clients that support PC's long file name format.'
