Re: How to install 2 set of Oracle Clusterware into the same machines?

the situation is complicated. I didn't mention the whole story in my original post because I think it is not related to technology.

Actually the story is:
these 2 machines are the backup site of a 2-node 10.2.0.4 RAC product database, using the storage replication method instead of using dataguard, the OCR and Voting and all the datafiles are synced in disk volume level, the disk volume cannot be opened, and cannot be changed when they are in sync mode. In case the product database is crash and can't recover easily, we will open the synced volume, startup the clusterware and the database. We don't want to lose this backup site, so we can't deinstall the 10.2.0.4 clusterware.

And now we want to use these 2 machines to build a new 10.2.0.5 RAC, so we have to install another clusterware and another RAC. since the synced storage can't be opened, so I assume it's just like the storage is not connected.
