Verifying the LAN-free configuration

To ensure LAN-free data movement, you must verify that the hardware and software components are configured correctly.

Verify LAN-free configuration by completing the following steps:

1. Start the storage agent:

   Change to the storage agent directory and issue the DSMSTA command.

   

   1. Change to the storage agent directory.
   2. Issue the DSMSTA command.
   

   1. Open the Windows Services management console.
   2. Right-click the TSM Stagent service and click Start.

   When the storage agent starts, it contacts all available shared libraries, including those libraries that do not have a defined path. As a result, a delay might occur during startup processing. The storage agent also determines if the Tivoli® Storage Manager server is a library client or library manager. If the server is a library client, the storage agent attempts to define itself to the library manager if it is not known to the library manager. When the storage agent communicates with the Tivoli Storage Manager server, Secure Sockets Layer (SSL) information is displayed to indicate when SSL is in use.

2. Specify the DISPLAYLFINFO=YES option in your server options file. Doing so allows the accounting records and summary table entries to report the storage agent name.
   Important: This option might cause existing outboard automation that relies on the summary table or accounting records to fail to recognize some activities for a selected client. Before you set the DISPLAYLFINFO option, consider how this outcome can affect your environment.
3. Determine which destinations for a node are capable of LAN-free data movement by issuing the VALIDATE LANFREE command. The output of this command also provides explanations about destinations that are not LAN-free capable. Use this information to correct your configuration before you proceed to the next step.
4. Run a backup operation from the client.
5. If you receive a message that indicates that the backup failed, verify the following items:
   • The Tivoli Storage Manager server is running. If the Tivoli Storage Manager server is not running, the storage agent will not start.
   • The client, storage agent, and server are communicating with each other as expected.
   • The device driver on the storage agent is running.
   • The paths to the drives are correctly defined.
   • All drives in a library are defined paths from the server.
   If you try the backup operation again after the first failure, the client attempts to use the LAN connection for data movement. To force LAN-free data movement, stop and restart the client.
