If we check on oracle support, we can use [ID 949073.1] ... That's helpful issue to fix.
To run older databases on 11gR2 ASM and Clusterware we need to create a persistent configuration for the nodes(pinning a node). Because Cluster configuration in 11gR2 is dynamic. This dynamic configuration is incompatible with older database releases.
On Oracle Document about "Pinning Cluster Nodes for Oracle Database Release 10.x or 11.x".

Hi Surachart,
I am planning an upgrade of an oracle RAC database 11gR1 to 11gR2 which is sharing the ASM instance (same ASM disk groups) and the clusterware with one other 11gR1 instance. can you please let me know if i need to pin the other 11gR1 instance while doing the upgrade to 11gR2 for the first one?
thank you for you help
Kumar
I'm curious what you want to do. You should upgrade 11gR1 Cluster -> 11gR2 Grid Infrastructure ....
After you've done ... you are upgraded RAC + ASM .... you may check "./olsnodes -t -n" ... nodes are pinned .. if not you can pin them
and then upgrade database
thank you for your quick reply. it's just that i am not clear on the different steps to followin.
here is the current environment:
1) 2 databases 11gR1 (1 RAC UPLTEST, 1 standalone UPLDEV) both using same ASM instance)
2) cluster has one home, database one home seperate
3) ASM under database home
can you please let me know the steps? basically i want to upgrade UPLTEST to 11gR2 (use SCAN and move OCR and voting under ASM).
no technical commands required just steps and order (should it be done on the 2 nodes?)
thank you for your help
Kumar.
1. Upgrade Cluster -> Grid Infrastructure (RAC + ASM)
*** on 11gR2, ASM is used in Grid Infrastructure.
2 . If you not upgrade database. You can start database (rac) and database standalone. If error as me ... check nodes and pin them
