Upgrade clusterware from 10.2.0.4 to 11.2.0.2 on HP-UX Itanium
I ran the runInstaller on the 11.2.0.2 while all my databases are up in a RAC cluster 10.2.0.4
Because the option "Upgrade Oracle Grid Infrastructure or Oracle ASM" did not allow me to ugrade ONLY the clusterware (since I can do rolling upgrade my clusterware but I have to have a complete outage if I upgrade my Clusterware and ASM at the same time)
Thus
I had selected "Install Oracle Grid Infrastructure Only".
So how can I upgrade the Clusterware to 11.2.0.2 after completing the "Install Oracle Grid Infrastructure Only" .
I assume this will be a rolling upgrade for the clusterware (one node down at a time)
