Cause

There is a firewall blocking NFS server connectivity between the scan host and the storage server.

Solution

See the RedHat documentation for configure NFS on the firewall:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/storage_administration_guide/s2-nfs-nfs-firewall-config

Review the rpcinfo configuration on the NFS server to see port requirements:
