While it supposes to be:

This can happen for the following cases.

Case I

With 11.2 Grid Infrastructure, using dbca to create a RAC database from a 10.x or 11.1.x ORACLE_HOME.

$ORACLE_HOME/cfgtoologs/dbca/trace.log shows:

[main] [10:36:4:10] [OCR.<init>:259] Primary Group of Current user: oracle
[main] [10:36:4:11] [HASContext.getInstance:200] Module init : 24
[main] [10:36:4:11] [HASContext.getInstance:223] Local Module init : 24

Case II

RDBMS is at the same release as CRS or Grid Infrastructure, RDBMS is installed with Real Application Cluster option

Case III

RDBMS is at the same release as CRS or Grid Infrastructure, RDBMS is installed on each individual node without selecting Real Application Cluster option.

Case IV,  V,  VI & VII

Grid Infrastructure and RDBMS are on the same release, they are installed as different user: grid and oracle. Grid Infrastructure is running on all nodes, RDBMS is installed with RAC option.
