Hello Senthil,
Check the contents of the folder /usr/sap/G1X/SYS/global/sapcontrol.
There, you should see only one file per instance of the G1X system.
Each filename will have some numbers separated by the underscore character ("_"), and it will end with the hostname (or virtual hostname) where the instance is running.
If you see duplicate files related to the ASCS instance, check out the SAP note 1873918, as its solution could also help you in this case.
Regards,
Isaías
