Managed System for SAN Storage Agent User's Guide


Step 6. Client System

During this final step you will start the storage agent and verify the LAN-free configuration.

Start the Storage Agent

Start the storage agent as follows:

When the storage agent starts, it determines if the TSM server is a library client or library manager. If the TSM server is a library client, the storage agent uses information about the library manager from the library client in order to cross define itself to the library manager.

Verify the LAN-free Configuration

To verify that you have configured your system correctly for LAN-free data movement, perform the following procedure:

  1. Run a backup operation from the client. Verify that the backup is LAN-free by using a TSM Administrative Command Line client to login to the TSM server and storage agent to verify 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 TSM server should show a very small amount of bytes received (metadata) for the same node. If the node's session exhibits this behavior, and you receive a message stating that the backup has been successful, you have configured your system correctly.
  2. Ensure the following if you receive a message saying that the backup has failed.
    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.
    1. The TSM server is running. If the TSM server is not running, the storage agent will not start.
    2. The client, storage agent, and server are communicating with each other as expected.
    3. The paths to the drives are correctly defined.
    4. All drives in a library have defined paths from the server.

Determining Whether the Data Movement was LAN-free

Use the following guidelines to help determine whether the data movement is using the LAN-free environment:
