Server: ORA_SRVR
Path:/u00/grid/oracle/product/12201/grid
Step 1) Change directory to grid and run deinstall command
[oracle@ORA_SRVR grid]$
[oracle@ORA_SRVR grid]$ ./deinstall
-bash: ./deinstall: Is a directory
[oracle@ORA_SRVR grid]$
[oracle@ORA_SRVR grid]$
[oracle@ORA_SRVR grid]$ cd deinstall/
[oracle@ORA_SRVR deinstall]$
