Managed System for SAN Storage Agent User's Guide
During this final step you will start the storage agent and verify
the LAN-free configuration.
Start the storage agent by changing to the storage agent directory and
issue the following command:
dsmsta
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.
To verify that you have configured your system correctly for LAN-free data
movement, perform the following procedure:
- 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.
- 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.
- The TSM server is running. If the TSM server is not running, the
storage agent will not start.
- The client, storage agent, and server are communicating with each other as
expected.
- The paths to the drives are correctly defined.
- All drives in a library have defined paths from the server.
Use the following guidelines to help determine whether the data movement is
using the LAN-free environment:
