i. Run ps -ef |grep cm tocheck the CM process number. The CM process number includes snas_cm.
ii. Run kill -9 process number to end the CM process. The daemon will automatically start the CM process.
d. Restart the DeviceManager. Run cd/opt/deviceManager/bin to go to the /bin directory.Then, run sh restart.sh.
