If the change of AllowEnhancedReader from YES to NO is correct, follow the procedure in z/OS DFSMS Advanced Copy Services for the enhanced multiple reader disablement before continuing with volume resynchronization through the XADDPAIR command. If the parameter change is incorrect, issue the XSUSPEND command with TIMEOUT parameter, update the PARMLIB, and issue XSTART command again.
