The server received an APPE (append) or STOR (store) command while UNIXFILETYPE=FIFO was configured. The FTP server attempted to create the named pipe while processing the command, but could not. See the UNIXFILETYPE (FTP client and server) statement in z/OS Communications Server: IP Configuration Reference for more information about the UNIXFILETYPE configuration option.
Command:
put /tmp/a /tmp/a/b/a
Binary tagged file translated with current data connection translation table
>>> PORT 9,2,1,3,4,49
200 Port request OK.
>>> STOR /tmp/a/b/a
550 command STOR fails - unable to create named pipe /tmp/a/b/a
Command:
The command is rejected.
Report the error to the system programmer.
Inspect the FTP server syslog trace for information about the failure. Activating any FTP server trace option is sufficient to capture trace information when FTP cannot create a named pipe. If FTPLOGGING is active, messages EZYFS68I and EZYFS69I in syslog will include diagnostic information. Use the information in the syslog trace to correct the problem.
See the system programmer response.
