Diskgroup is not compatible for database usage

Diskgroup "+DATA" is not compatible for
database usage. Database compatible attribute of
diskgroup should be the same or lower than the database
compatible initialization parameter value.
Database compatible parameter is set to "11.2.0.0.0"
and the diskgroup database compatibility attribute is set
 to "11.2.0.2".  

Solution: go to OH/assistants/dbca/templates
and edit the line name="compatible" value="11.2.0.0.0"

   <InitParamAttributes>
      <InitParams>
         <initParam name="db_name" value=""/>
         <initParam name="dispatchers" value="(PROTOCOL=TCP) (SERVICE={SID}XDB)"/>
         <initParam name="audit_file_dest" value="{ORACLE_BASE}/admin/{DB_UNIQUE_NAME}/adump"/>
         <initParam name="compatible" value="11.2.0.0.0"/>
         <initParam name="remote_login_passwordfile" value="EXCLUSIVE"/>
