Validating your LAN-free Configuration

Once you have configured your Tivoli Storage Manager client for LAN-free
data movement, you can verify your configuration and server definitions
by using the VALIDATE LANFREE command. This command allows you to
determine which destinations for a given node using a specific storage
agent are capable of LAN-free data movement. 

The VALIDATE LANFREE command can also be used to determine if there is a
problem with an existing LAN-free configuration. You can evaluate the
policy, storage pools, and path for a given node using a given storage
agent to ensure that an operation is working properly. 
To determine if there is a problem with the client node FRED using the
storage agent FRED_STA, issue the following: 

     validate lanfree fred fred_sta 

The output will allow you to see which management class destinations for
a given operation type are not LAN-free capable. It will also report the
total number of LAN-free destinations. 
See the VALIDATE LANFREE command in the Administrator's Reference for
more information.
