The XRC Control Address space (ANTAS000) could not disable or enable clustering, because of existing coupled XRC sessions. The change_requested field might be either ENABLE or DISABLE depending on the type of change requested.
Cluster status remains unchanged.
See System data mover return and reason codes for an explanation of the return code, which describes the specific condition impeding the status change. Check the ANTXIN00 Parmlib member for incorrect ClusterMSession and MHLQ values. If they correctly reflect the desired configuration, issue XCOUPLE DELETE or XCOUPLE PURGE commands for all XRC sessions previously coupled through the cluster, or coupled to the master session currently specified in ClusterMSession. Then issue command F ANTAS000,CREFRESH to reinitiate cluster setup processing
