Goal

Localconfig command is used for single instance RDBMS to config cssd which support ASM.
On RAC system, cssd is part of CRS, ASM will be supported once CRS is installed and running.
There is absolutely no requirement to run localconfig on RAC system and it should never be used on RAC system as it will destroy CRS configuration.

In this note, we will discuss a few scenarios related with localconfig command being run on RAC system, include "localconfig delete" and "localconfig reset" and how to restore CRS configuration if localconfig script accidentally run on RAC system for any reason.
