550: command command is not available for pathname

Explanation

The client issued the command command to the FTP server. The FTP server was not able to execute the command for pathname, for one of the following reasons.
  • The file was not a z/OS® UNIX file. command is supported only for z/OS UNIX files.
  • An I/O error occurred while the FTP server was reading from the file system.
  • For FILETYPE=JES, a pathname must be in the form of JOBxxxxx, TSUxxxxx, APCxxxxx, or TSUxxxxx.
If command is SIZE, additional reasons might cause the command to be rejected:
  • The file size is too large to be represented by a C int type variable (two words of storage). Command is not supported for files of sizes larger than can be represented as an int type variable.
  • The file is a z/OS UNIX file, but it is not a regular z/OS UNIX file as defined by UNIX System Services. SIZE is supported for regular z/OS UNIX files only.

System action

The command command is rejected. The FTP server waits for the next command from the client.

User response

Verify pathname was entered correctly, and that pathname represents a z/OS UNIX file of a supported size and type, as applicable. Correct any errors, then issue command again. If the problem recurs, report it to the system programmer.

System programmer response

Error messages related to pathname retrieval are written to syslogd if ftp server traces are enabled. If syslogd is not active, the error messages will be written to the operator console. Correct any errors, then have the user issue command again.
