Hi, For oracle.install.option I chose HA_CONFIG, looks like I should have used CRS_SWONLY. OK I worked this out by actually been given the means to run an interactive session and then save a response file. I have not gone through it in detail but it includes settings for "scanName" and "clusterName" that do not exist in reality. No way I would have worked this out myself.
