ADR946I
(ttt)-mmmmm(yy), A FAILURE OCCURRED WHILE ATTEMPTING TO PERFORM FLASHCOPY FROM EXTENT src_starting_c:h-src_ending_c:h TO EXTENT tgt_starting_c:h-tgt_ending_c:h. DIAGNOSTIC INFORMATION: return_code-reason_code[-reason_code_modifier]

Explanation

DFSMSdss attempts to process the extent using FlashCopy® and the System Data Mover (SDM) fails with listed diagnostic information. The system might issue this message for diagnostic purposes if the DEBUG(FRMSG(MIN | SUM | DTL)) or the FASTREPLICATION(REQ) keyword is specified.

System action

DFSMSdss attempts to move this extent using traditional data movement methods unless FASTREPLICATION(REQUIRED) is specified. DFSMSdss DEFRAG operation continues and FlashCopy will be attempted for the rest of the extents. The return code is zero.

Operator response

None.

Programmer response

See System data mover return and reason codes following DFSMSdss messages in z/OS MVS System Messages, Vol 1 (ABA-AOM) for an explanation of return_code and reason_code.
