Client accepts SRESTART subcommand, but server rejects RESTART

Use the following checklist if the client accepts SRESTART subcommand, but server rejects RESTART:

• Verify that the server supports stream mode restarts by issuing a FEAT command to the server. The FEAT reply l includes the keyword REST_STREAM if the server supports stream mode restarts.
• Some FTP servers other than z/OS® FTP servers reply to the FEAT command with REST_STREAM when they support stream mode restarts in one direction only, such as server to client file transfers. Contact the provider of the FTP server software to verify the server support stream restarts for the direction of the transfer you are attempting.
• See z/OS Communications Server: IP User's Guide and Commands for information about the feature subcommand.
• Verify that the server has recreated the environment extant during the failed file transfer.
• Did you restart a retrieve and SBSENDEOL is configured to a value other than CRLF at the server, and the server is a z/OS FTP server? If so, you cannot restart the file transfer. Retrieve the file from the server again.
