550: Command `cmd` fails: `filename` is a pipe or FIFO.

Explanation

The FTP server received a command that specified an existing file on the FTP server host while UNIXFILETYPE=FILE was configured. The existing file is a z/OS® UNIX named pipe or FIFO special file. The command must specify a z/OS UNIX regular file when UNIXFILETYPE=FILE is configured.

In the message text:

cmd: The command that the FTP server received.
filename: The path name of the named pipe or FIFO special file.

User response

Do one of the following actions:

Reissue the command with the name of a file that is not a pipe or FIFO special file specified.
Change the UNIXFILETYPE configured value by sending a SITE command with the UNIXFILETYPE=FIFO parameter to the FTP server, and reissue the file transfer.
- If your client is z/OS FTP, use the SIte subcommand.
- For other clients, use the QUOTE subcommand to send a SITE command to the server.
See the SIte subcommand in z/OS Communications Server: IP User's Guide and Commands for more information.
