Manual switching | alive Old master does't become new slave

[GoogleCodeExporter]

While switching the master with " masterha_master_switch --master_state=alive 
--new_master_host=host2"

lets take host1 is old master and it is in alive state, host2 is new master ( 
which we wants to ). 

why this tool is not taking care of alive old master. As it is in alive state, 
why can't we switch this to new slave.

What are the possible cases that we will think about manual switching with 
alive master.

Thanks for update, Its working as expected But, 

Facing problem with vip switching.
I'm using master_ip_online_change_script (sample script), as 
masterha_master_switch not taking master_ip_failover_script .

Is master_ip_online_change script for switching the vips ?

What is the role of master_ip_online_change.

I'm confusing about this. Please explain. I'm very eager to use mha in 
production servers

In your case, you are doing online master switch (not dead master failover) so 
use master_ip_online_change_script 
(https://code.google.com/p/mysql-master-ha/wiki/Parameters#master_ip_online_chan
ge_script). MHA calls an external script to do whatever you want. Rotating vip 
is one of the most common use cases. Since the way to change master's ip 
address depends on users' environment, MHA allows users to write any script 
here.
