I'm trying to upload a file from linux to z/OS via ftp (with filezilla). The upload fails with this error:
550-SVC99 RETURN CODE=4 S99INFO=0 S99ERROR=38668 HEX=970C S99ERSN code X'000042CE'.
550 Unable to create data set TESTUSER.UNIX.USERLIB.SOME for STOR command.
Does anyone know how to interpret this message?
SVC99, also known as DYNALLOC, is the dynamic allocation routine on z/OS. Documentation is voluminous, see the IBM Documentation for z/OS and look under z/OS MVS -> z/OS MVS Programming: Authorized Assembler Services -> Dynamic Allocation -> Requesting Dynamic Allocation Functions -> Interpreting Error Reason Codes from DYNALLOC. For z/OS 2.2 that path should take you here.
Meaning: Severe SMS VTOC service error.
Application programmer action: Check field S99ERSN for a non-zero value. A non-zero value in S99ERSN is a reason code. See SMS reason code (S99ERSN) for the possible reason codes. If the system displayed message IKJ56893I, SMS messages for the error follow IKJ56893I. If the system displayed message IKJ56894I, no messages were returned. Request the message processing option of dynamic allocation to obtain related messages and resubmit the request. Because SMS creates entries in the logrec data set, if you still cannot obtain messages, locate the logrec data set entry for the error that corresponds to the reason code. If you need further assistance contact your system programmer.
Corresponding Messages: IKJ56893I (messages were displayed) or IKJ56894I (messages not displayed).
Following the link, your S99ERSN code is documented as...
42CE (17102)
Meaning: While trying to define a non-VSAM data set, a catalog error or exceptional condition caused the allocation attempt to fail.
Application Programmer Action: Examine the return code and reason code in accompanying message IGD17102I in z/OS MVS System Messages, Vol 8 (IEF-IGD).
So there should be an accompanying message IGD17102I in the system log with even more information. Looking at the documentation, I'd contact your support staff as this doesn't look like something you can fix yourself.
