Yes, if you create that export and chmod -R 777 that directory, then I'd have it configured like this:
[xcp]
catalog = utility-mgmt-004:/opt/NetApp/xFiles/xcp/catalog
If utility-mgmt-004 isn't in DNS, add it to /etc/hosts so that it resolves.
And then try to mount manually from the XCP system:
sudo mkdir /mnt/test
sudo mount -t nfs utility-mgmt-004:/opt/NetApp/xFiles/xcp/catalog /mnt/test
sudo touch /mnt/test/test.txt
If OK, umount that share and use XCP.
That's how I got it to work last time I tried.
If this doesn't work, I will try tomorrow using the latest release.
