[INS-06006] Passwordless SSH connectivity not set up between the following nodes(s)

Symptom: Installing 11.2.0.4 Grid Infrastructure patch set, runInstaller reports error: [INS-06006] Passwordless SSH connectivity not set up between the following nodes(s): [racnode1].

Root cause: Hostname is in mixed case (upper and lower)

Passwordless set up between the nodes in the RAC cluster was done using hostnames in lower case.

Solution: change the hostnames to lower case in the /etc/hosts file and re-run the installer.
