Problems Creating a 10.2.0.4/11.1.0.7 DB on ASM 11.2.0.1

Hello,

I am having some problems creating a 10.2.0.4/11.1.0.7 DB on top of ASM 11.2.0.1 using dbca. I can't get passed step 7 when I select ASM as storage.

Here are the steps that I've done:

- Install a 2 node 11.2.0.1 RAC cluster with ASM and Clusterware, this worked fine.
- Set the parameter 'DB Compatibility' to 10.1.0.0.0 on the disk groups in ASM.
- Installed & configured a 11.2.0.1 Database on this cluster, this worked fine.
- Installed 10.2.0.1 DB software in separate Oracle Home.
- Upgraded the 10.2 installation to 10.2.0.4.
- Installed 11.1.0.6 DB software in separate Oracle Home.
- Upgraded the 11.1 installation to 11.1.0.7.

Now, when I run dbca (this occurs both from the 10.2 and 11.1 O_H) at step 7 in the Wizard I select "Select ASM as Storage" then when I press next I get this error message:

'DBCA could not startup the ASM instance configured on this node. To proceed with database creation using ASM you need the ASM instance to be up and running. Do you want to recreate the ASM instance on this node?'

In the dbca log file I can see "ASM present but not startable, querying user.."

What do I need to do in order to be able to create a 10.2 DB on 11.2 ASM? I have also tried to set TNS_ADMIN to the network/admin directory under the grid infrastructure, however, this did not work eitther, I still get the same problem.

Any ideas what measures I need to do in order to be able to create a 10.2 / 11.1 DB on top of the 11.2 Grid Infrastructure?

Thanks
