Inactive ESXi NFS Mounts

After moving an ESXi host from one site to another, I realized we didn't unmount all the NFS mounts.  Upon restarting, the original datastores were still listed but greyed out.  Clicking on "Delete" resulted in an error message.










This is easily fixable:

1. SSH to your host
2. Use esxcfg-nas -d <datastore name>
3. Reboot host
