(DP) Support Tip: Number of devices used is smaller than MIN value of load balancing.

Problem
-------
Data Protector backups to a StoreOnce device fail with
   "Number of devices used is smaller than MIN value of load balancing."



Solution
--------
In this case the problem was because the Gateway was not configured correctly.
The client machines could not resolve the Gateway's hostname.
So the Clients could see Zero devices, hence the message.

Entering the Gateway's hostname/ip address in the client's host file,
so clients could resolve the gateway, resolved the problem.
