But if Ping and SSH did work between nodes via interconnect interface and still ocssd log did complain about interconnect HeartBeat (no network HB) then interconnect interface is jammed. You can try to restart it to get it fixed (NOTE! It is usually the working node interconnect interface that is needed to restart (like error message is saying in ocssd.log (it is complaining node1)). For example if node2 CRS is not starting then restart node1 interconnect interface ) :
[root@<node1> <node1>]# ifdown eth1
[root@<node1> <node1>]# ifup eth1
And check that eth1 is looking ok:
[root@<node1> <node1>]# ifconfig

Best idea : upgrade Gi to 11.2.0.4

problems with 4 TB hard drive in B110i raid controller
The Smart Array B110i controller is not compatible with drives larger than 2TB in RAID. It's not well-documented or noted online, but you've run into a product limitation. Remember, this controller predates the introduction of 4TB disks by a bit.
If you need to use those specific 3rd party disks, then you're going to have to swap controllers or use software RAID.
