10g database with 11g Grid infrastructure

11gR2 Grid Infrastructure with lower version DB

I had a situation where I need to have 11gR2 infrastructure Grid with lower version Database 10gr2.
faced issues starting the database after 11gr2 grid install.

Steps I have done before starting the DB

x. Install Grid Infrastructure 11.2.0.3
x. Install 10.2.0.1
x. Apply patch set on 10.2.0.1 to 10.2.0.4


DB start up was giving the error

[oracle@xd3cfp001 dbs]$ sqlplus '/as sysdba'

SQL*Plus: Release 10.2.0.4.0 - Production on Thu Nov 17 14:28:08 2011

Connected to an idle instance.

SQL> startup nomount
ORA-29702: error occurred in Cluster Group Service operation
SQL> exit

This is due to the fact that nodes were not pinned to grid infrastructure.

atsdb1.ea.com[ATS4A]$ /opt/oracle/grid/11.2.0/bin/olsnodes -t -n
atsdb1        1       Unpinned
atsdb2        2       Unpinned


To pin, I had to run the below commands


/opt/oracle/grid/11.2.0/bin/crsctl pin css -n atsdb1  atsdb2


atsdb2.ea.com[APF11G]$  /opt/oracle/grid/11.2.0/bin/olsnodes -t -n
atsdb1        1       Pinned
atsdb2        2       Pinned
