Node can not join cluster after RAC HA Testing

Question

Dear forum,
We are performing RAC failover tests according to document "RAC System Test Plan Outline 11gR2, Version 2.0". In testcase #14 - Interconnect network failure (11.2.0.2 an higher), we have disabled private interconnect network of node node1 (OCR Master).
Then - as expected - node node2 was evicted. Now, after enabling private interconnect network on node node1, i want to start CRS again on node2. However, node does not join cluster with messages:

Rebooting node2 did not help. Node1 which was online all the time (although private interconnect interface was unplugged for a few minutes and then plugged back in). I suppose that if we reboot node2, the problem will disappear. But there should be solution, which keeps availability requirements.
Setup:
2 Nodes (OEL5U7, UEK)
2 Storages
Network bonding via Linux bonding
GI 11.2.0.3.1
RDBMS 11.1.0.7.10
Any ideas?

Answer 1

I have found a solution myself:
[root@node1 trace]# echo -eth3 > /sys/class/net/bond1/bonding/slaves
[root@node1 trace]# echo -eth1 > /sys/class/net/bond1/bonding/slaves
[root@node1 trace]# echo +eth1 > /sys/class/net/bond1/bonding/slaves
[root@node1 trace]# echo +eth3 > /sys/class/net/bond1/bonding/slaves
Now node2 is automatically joining the cluster.
