The server refuses a request to start a server session because the requesting server name is not defined in the server database, or the requesting server definition does not have a SERVERPASSWORD, or a password or node name is not setup for virtual volume use on the source server.
Server operation continues.
Register the requesting server name with the server before establishing a session, or update the existing requesting server definition and set a SERVERPASSWORD. An authorized administrator must use the DEFINE SERVER or UPDATE SERVER command to register the requesting server and set the password. For a virtual volume environment, the source server must have a definition for the target server which includes a node name and password.
