OK, we finally have a working Oracle Cluster. Praise God! I wanted to add some of the new things that have been discovered since the last post.
Make sure if you are not going to use HP ServiceGuard on your RAC cluster, that all of ServiceGuard has been stopped and uninstalled. Don't leave any libraries laying around. We found out this the hard way, after spending over a week trying to figure out why the Oracle Installer was acting so crazy and bizarre.
Here are the symptoms: First, if the OUI does not give you the option to add the other nodes and you have to use a configuration file, this is a red flag that the OUI thinks that you are using some vendor cluster software (in this case HP ServiceGuard) instead of using Oracle's. Secondly, if you have some variables that are not assigned (see previous post) in the rootconfig script this indicates that it is not really trying to install rather it is trying to upgrade/update the OCR.
If for some reason, you get the clusterware services running on one of the nodes but it doesn't start on the others and locks up. It probably means that your removal of ServiceGuard was incomplete and left a few SG libraries laying around.
We found all of this out the hard way because HP installed and started ServiceGuard when they installed the HP 9000 Superdome!
Finally, here is an undocumented procedure for HP-UX Itanium Clusterware 10gR2 installation: Shutdown the VIP interface BEFORE beginning the install. If you don't, an error message will appear saying that the VIP interface is being used by another system. Then you have to shut the VIPs down before continuing the install. This is weird because the VIP must be up in order for cluvfy nodecon to work.
