"Oracle Grid Infrastructure is not configured properly. ASMCA needs Oracle Grid Infrastructure to configure ASM" error while creating ASM instance using ASMCA

While creating a ASM instance for standalone server using "asmca", we received the following error.

Intially the Oracle Grid Infrastructure was installed using following option "Install Oracle Grid Infrastructure software Only"

Solution

Execute the "root.sh" again as root user. "root.sh" can be found on grid home.

------------------------

[root@coltdb08 grid]# ./opt/11.2.0/grid/root.sh

Performing root user operation for Oracle 11g

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /opt/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of "dbhome" have not changed. No need to overwrite.

Finished running generic part of root script.

Now product-specific root actions will be performed.

To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:

/opt/11.2.0/grid/perl/bin/perl -I/opt/11.2.0/grid/perl/lib -I/opt/11.2.0/grid/crs/install /opt/11.2.0/grid/crs/install/roothas.pl

To configure Grid Infrastructure for a Cluster execute the following command:

/opt/11.2.0/grid/crs/config/config.sh

This command launches the Grid Infrastructure Configuration Wizard. The wizard also supports silent operation, and the parameters can be passed through the response file that is available in the installation media.

---------------------

You can see there is separate script for creating Grid Infrastructure for stand-alone server. Execute the script as root user

--------------------

[root@coltdb08 grid]# /opt/11.2.0/grid/perl/bin/perl -I/opt/11.2.0/grid/perl/lib -I/opt/11.2.0/grid/crs/install /opt/11.2.0/grid/crs/install/roothas.pl

Now try to create the ASM instance using "asmca", it will successfully create the ASM instance.
