Explanation
 VTAM® started
an SVC dump (SDUMP) for an abend, or for a first-failure-data-capture
(FFDC) detected error, and the system could not complete the dump
successfully.   code indicates the return code received from MVS™ SDUMP and might be one of the
following:  4
The system obtained only a partial dump.  The dump data set or
file might be too small.  When code is 4, reason will
be X'00'.
8
The system was unable to schedule a dump.  When a return code
of 8 is received, a hexadecimal reason code (reason)
is returned.

  reason indicates the cause
of the SDUMP failure.

System action
 VTAM takes
no further action to obtain a dump.  Other processing continues.

Operator response
 Save the system log for problem determination. 

System programmer response
 If code is 4,
look for system message IEA911E for further information.  Message
IEA911E includes reason codes that explain why the system could not
execute a complete dump. Message IEA911E is documented in the z/OS MVS System Messages, Vol 6 (GOS-IEA).
 If code is 8,
see z/OS MVS Programming: Authorized Assembler Services
Reference LLA-SDU for an explanation of the return code and
reason code for the SDUMP macro.
