Kartik,

The process for v5.5+ should, ideally, look like:

mysql> stop slave;
mysql> reset slave all;

on the secondary node you wish to promote. This will remove the failed primary node, and promote this secondary replica within your cluster.

Keep in mind that earlier versions of MySQL server may require an additional step before the reset:

change master to MASTER_HOST='';

on the node you wish to promote.
