Oralce DB 10g on Oracle 11gr2 Grid

$ olsnodes -t
node1        Unpinned
node2        Unpinned

If the cluster is a newly created 11.2 Grid Infrastructure (CRS), and you want to create pre 11.2 RAC db, you need to pin the corresponding nodes. In our case their status are showing as Unpinned. If Grid Infrastructure was upgraded to 11.2, then you no need to pin. Read more Installing Pre 11.2 Database in 11GR2 Grid Infrastructure environment at My Oracle Support Document Id: 948456.1
