Verifying and updating client node information (z/OS media server environments)

When you configure LAN-free data movement, you must register client nodes and provide policy information about client nodes. You can also restrict when a client node uses a LAN-free path.

Procedure

Complete the following steps to verify client node information:

  1. Identify the client node or nodes that uses the storage agent.
    In a typical environment, a storage agent is used only by the client node that is on the same system as the storage agent. However, you can configure two or more client nodes to use the same storage agent.
  2. Verify that the nodes are registered. If they are not registered, you must register them.
  3. Verify the policy information for the nodes.
    The copy group for backup and archive must point to a storage pool that has a LAN-free path for a particular storage agent. You define drive LAN-free paths and make them available for the storage pool. To view the destinations that are capable of LAN-free data movement, you can issue the VALIDATE LANFREE command on the server.
  4. After you verify the registration and policy information for the nodes, you can place restrictions on when a node can use the LAN-free path.
    The node attributes DATAWRITEPATH and DATAREADPATH determine the restriction that is placed on the node:
    • To use only the LAN-free path on backup and archive operations, specify DATAWRITEPATH.
      Important: Backup and archive operations can fail if the LAN-free path is unavailable.
    • To use the LAN path on restore and retrieve operations, specify DATAREADPATH.
