 If you try to google it, you get plenty of results about 11g installation, which do not really help. **Turns out, this is actually a bug in 12.1.0.2. Clusterware fails to configure if IP address contains octet with value 255.** Yeah, I was installing in subnet xxx.xxx.255.xxx/24 so it was my case. Oracle released a patch 19777496 which solves this "failure occurs when you install clustering software version 12.1.0.2 on some valid IP addresses".
-In the original post there is also a howto on installing 12.1.0.2 in such setup. In a hutshell, it is patching GRID after installation but before running root.sh. I'm not a big fan of this approach so for me the solution is simpler - use different subnet. ;-)
