Hi ALL,
We have Active - Passive CLuster
I made a little mistake. on the Cluster SQL configuration.

SQL server Configuration Manager --> SQL server 2005 Network Configuration --> Protocols for MYDB

Right clicked on TCP/IP --> Properties --> IP Addresses (TAB)

Here i changed the "TCP Dynamic Ports" and " TCP Port" with same port number (2977), accidental mistake.

Now SQL server is failed to start. I see the below in Eventlog.

Event Type: Error
Event Source: MSSQL$MYDB
Event Category: (2)
Event ID: 26023
Date: 2/23/2007
Time: 4:09:03 PM
User: N/A
Computer: SQL2005_64CLUSTER
Description:
Server TCP provider failed to listen on [ xxx.xxx.xxx.xxx <ipv4 2977].
Tcp port is already in use.

I believe you can change with SQL configuration Manager...

How to configure an instance of SQL Server to listen on a specific TCP port or a dynamic port

I just looked up in Google again for good measure and I saw this link and it worked for me.

It was so quick and easy.

http://www.sqldbadiaries.com/2010/10/25/addremove-checkpoints-manually-on-a-cluster/

get teh list of cluster resources in teh host by typong cluster res and identify teh name of the resource.

In my case the SQL instance is named instance and so I had to modify the line accordingly.

remove checkpoint with:

cluster res "SQL Server" /removecheck: "Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLSERVER"

Make the port changes in the SQL Server Configuration manager for the TCP protocol and start teh instance .

Then run the following to add teh checkpoint.

cluster res "SQL Server" /addcheck: "Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLSERVER"

Fail over form node to node to verify that all is well.

It was that simple and very quick.

By the way , next time , I will choose a random/different value for the port number for fixed port thatn the dynamic one showing on the configuration manager.
