INS-40915 : Installer detected the presence of Clusterware

There was a failed installation of Oracle 12c grid infrastructure due to some storage issues, later these nodes were cleaned using the deinstall procedure.

Once the nodes are cleaned, proceeded back with the installation and encountered the following error:

To solve this issue check "/etc/oracle" directory on nodes for which its failing. When we check both nodes, we found this directory existed on node2 and not deleted by deinstall procedure.

Action Plan:

- Delete "/etc/oracle" directory

- Retry the Installation and it should proceed without issues.

thanks for reading :)
