Running the utility dcacheck reports the below error message
DCA_CHECK_ERROR host(smdw): Error: Database state Up. DB is not the active DB and the gpsyncmaster processes are not running
This is a known issue with dcacheck and worked internally using the bug DCA-9424
The issue is fixed at the version ISO 184.108.40.206 for any other previous version the error can be ignored if the standby is in sync as per the output from "gpstate -f".
