[INS-40401] The Installer has detected a configured Oracle Clusterware home on the system.

RAC installation fail due to some misconfiguration

When we reinstall RAC,we see the below error

It is better to deconfigure and cleanup the debris which are partially configured in grid home

Deconfigure the oracle high availability using perl script on the grid home
