5.3.2 Verifying User Privileges to Update Remote Nodes
You must insure that operations that are performed on multiple nodes can be performed during installation of the Oracle Grid Infrastructure software.
For the installation to be successful, you must use the same user name and password on each node in a cluster or use a domain user. You must explicitly grant membership in the local Administrators group to the installation user on all of the nodes in your cluster.
If the remote node does not appear in the registry tree or you are prompted to fill in a username and password, then you must resolve the permissions issue at the operating system level before proceeding with the Oracle Grid Infrastructure installation.
