Message: unexpected data received

Explanation: Message communications (handshaking) was not correct.

Recommended Action:

  • Verify that the correct version of software is running on all servers.

  • Examine the command output (if available) and the daemon and reqlib debug logs for a more detailed message on the protocol error.

    See "Setting Media Manager debug logging to a higher level" in the NetBackup Logging Reference Guide.

  • Retry the operation and examine the logs.

  • Ensure that no embedded whitespaces exist in the fields that do not allow embedded whitespace.
