ANR4794E
The NAS file server File server name failed to open an NDMP data connection to the TSM tape server. Please verify that the file server is capable of outbound data connections.

Explanation

During a NAS filer-to-server backup operation the data connection from the file server to the TSM server failed. This may occur because a firewall exists between the file server and the TSM server and is preventing outbound network connections on the file server. This may also occur if the network configuration of the system running the TSM server is reporting an invalid TCP/IP host address, for example "127.0.0.1".

System action

The TSM server backup operation on the file server fails.

User response

Verify that the NAS file server is capable of starting outbound network connections to the TSM server. Verify that the file server supports NDMP 3-way operations. Verify that the network configuration of the system running the TSM server is reporting a valid TCP/IP host address. .
