Damodar Reddy T resolved CLOUDSTACK-5679.
-----------------------------------------

    Resolution: Cannot Reproduce

When we are adding a rule to the iptables to block the connection it is not dropping connections which are already established and new connections are rejected to that DB node.. 

Kiran: I am not sure how to add a rule to drop even established connections as well, so I tested by stopping the db node and able to see exceptions in logs of 2nd MS node..

> Setup and issue details:
> 1)Created a CS setup with multiple MS say MS1 and MS2 with DBHA enabled. 
> 2)Created a DB replication has 2 db servers say DB1 and DB2. 
> 3)Initially the setup was in such a way that both MS1 and MS2 are talking to the DB1 and DB2 was acting as a slave. 
> 4)Then Blocked the communication from the MS2 to DB1 using the IPtables. 
> 5)When the connection is blocked from the MS2 to DB1 there is no error message shown in the logs and it simply switches to the DB2 .
