Enabling SSH and running 

esxcli storage nfs list

Listed no NFS Datastores either 

esxcli storage nfs add -H %IP-OF-SAN% -s /NFSNAME -v /NFSNAME 

brought up the Name was already in use. Removing and re-adding brought up an error that the IP of the NFS Share could not be access

esxcli storage nfs remove -v /NFSNAME 

Trying to Ping the Storage Server IP from the host did not reply a any pings

Login to the EMC and reboot the primary Storage Processor
