Bug/Abnormal behaviour in RAC

Yesterday night we were faced one issue with Oracle11. RAC
on RHEL6.4 Platform.

1. someone had deleted the ip root from one of the database server.
2. we came to know that DB2 is completely down but DB1 is up and running
3. correct the ip root which was deleted.
4. we tried to stop and start clusterware stack on DB2
5. db2 services not coming up
6. we tried to reboot the DB2 server three times
7. db2 services not coming up

we don’t have any clue after steps 4 to 7.

8. lastly we rebooted DB1
9. stop and start the cluster on DB2
10. started cluster services on DB2
11. DB1 is successfully comes up after reboot

We finally have both DB1 and DB2 up and running.
