ANR4975E
No Tcp port available for backup from NAS node to server.

Explanation

The server was unable to set up a TCP/IP port for use in backing up or restoring from or to NAS nodes and the server. The server uses a range of ports as defined by the NDMPPORTRANGE option. If none of these ports can be set up for use, backups or restores from or to NAS nodes and server native storage pools will fail. If the NDMPPORTRANGE option is not specified, the server uses ephemeral ports ( ports that the operating system assigns from a dynamic pool ). If the system runs out of usable ports, operations to or from NAS nodes and server native storage pools will fail.

System action

The specific operation is ended and server operation continues.

User response

Operating specific utilities, e.g. netstat, may be used to examine ports which are in use. It may be necessary to specify the NDMPPORTRANGE option ( which requires a server restart ), to provide a sufficient number of ports.
