Documenting server problems

If the problem is not caused by any of the common errors described in this section, collect the following documentation before calling the IBM® Support Center.

Documentation is divided into the following categories: essential and helpful (but not essential).

Essential
- Precise description of problem, including expected results and actual results
- z/OS UNIX FTP server dump (for abends)
- z/OS UNIX FTP server traces (see Diagnosing FTP server problems with traces for information about collecting FTP server traces)
  - Minimum for initial problem reporting: DEBUG BAS
Helpful
- FTP client output
  - If the FTP client is a z/OS® client, include a trace in the output by one of these methods:
    - Coding DEBUG statements in the client's FTP.DATA file.. See z/OS Communications Server: IP Configuration Reference for information about the DEBUG statement.
    - Invoking the FTP client with the -d or TRACE invocation option. See z/OS Communications Server: IP User's Guide and Commands for more information.
    - Specifying a DEBUG subcommand in the client command input stream before the affected transfer. Use this option only if the problem does not involve the initial establishment of the FTP control session.
- Server FTP.DATA data set
- TCPIP.DATA data set
- PROFILE.TCPIP data set
- ETC.SERVICES data set
- The reply from the STAT or XSTA command issued to the server.
  Guidelines:
  - Issue the STATus subcommand from the z/OS FTP client to retrieve STAT command output from the server. From non z/OS clients, you may have to issue QUOTE STAT to retrieve the output from the server.
  - Issue the STATus subcommand with a parameter from the z/OS FTP client to issue the XSTA command to the server. The XSTA command retrieves output related to that parameter only. From z/OS clients prior to V1R8, or from non-z/OS clients, issue QUOTE XSTA (parameter to retrieve the output from the server.
- Any console messages issued for resources experiencing errors.
- If applicable, sample data to re-create the problem
