This problem resolved. It was found that it is 4096 not 8192 per consistency group. So we have hit this maximum. For the cestpair commands the AG000 parameter should be AG010 for consistency group 01. This has enabled another 4096 pairs which will be in consistency group 1.
CESTPAIR DEVN(X'C5A9') PRIM(X'C005' AG000 X'A9' X'05') + SEC(X'C805' 11462 X'A9' X'05') + MODE(COPY) PACE(15) CRIT(NO) MSGREQ(NO) Where “AG000” parameter : A = Asynchronous mode G = Consistency group “00” = Consistency group number. “0” = Normal delay for command retry Hope it helps. Many thanks for help.
