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.
Step 5.2 Verify the LAN-free Configuration
To verify that you have configured your system correctly for LAN-free data
movement, perform the following procedure:
1. Specify the DISPLAYLFINFO=YES option in your server options file. This will
allow the accounting records and summary table entries to report the storage
agent name. Be aware that this option may cause existing outboard automation
that relies on the summary table or accounting records not to recognize some
activities for a given client. Make sure to consider how this may impact your
environment before setting this option.
2. Issue the VALIDATE LANFREE command to determine which destinations for
your node are capable of LAN-free data movement. For those nodes that are
not capable of LAN-free data movement, this command provides an
explanation as to why they are not capable. You can use this information to
correct your configuration before proceeding to the next step.
3. Run a backup operation from the client.
4. Ensure the following if you receive a message saying that the backup has
failed:
a. The Tivoli Storage Manager server is running. If the Tivoli Storage Manager
server is not running, the storage agent will not start.
b. The client, storage agent, and server are communicating with each other as
expected.
c. The paths to the drives are correctly defined.
d. All drives in a library have defined paths from the server.
Note:
If you retry the backup operation after the first failure, the client attempts to
use the LAN connection for data movement. The client will continue to use
the LAN until the client is stopped and restarted.
Determining Whether the Data Movement was LAN-free
Use the following guidelines to help determine whether the data is moving on the
LAN-free path:
v When the data transfers on a LAN-free path, a message displays informing you
that the client is starting a session with the storage agent:
ANR0415I Session session number proxied by storage agent name for node your node name
This message confirms that LAN-free data movement has occurred.
v You can also view the backup report issued when backup processing completes.
When LAN-free data movement has occurred, the number of ″LAN-Free Bytes
Transferred″ is greater than zero.
v Monitor the QUERY SESSION output against the node that is running the
LAN-free backup. Review the Bytes Sent and Bytes Received. You can perform
this action by using a Tivoli Storage Manager administrative command-line
client to login to the Tivoli Storage Manager server and storage agent to verify
that the proper sessions have been established. When LAN-free data movement
is occurring, a QUERY SESSION on the storage agent should show bytes
received (displayed as Bytes Recvd) for the node increasing to the total amount
of data being backed up. The QUERY SESSION on the Tivoli Storage Manager
