Thanks for your reply.
I want to deploy application on physical servers and I cannot use virtualization and VM. Furthermore methods like Vmware FT has some limitations like max no of VCPU and also RAM.
I think it should be much easier if I can use pacemaker as a cluster resource manager but I dont know how to introduce my application as a resource and how to route all traffic to my primary server and when server or application goes down traffic and requests route to other node.
Unfortunately my application is not like a service. normally my application gathers information from different servers and sends them to another servers thus methods like loadbalancer is not suitable for my scenario.
*************(floating IP)************
| ***route all traffic on every port ***|
| ******************************************|
ServerA*************************** ServerB
(APP) **************************(Stopped App)
I need a floating IP for my cluster and when serverA goes down All traffic switch to ServerB( Input and Output) also cluster start Stopped application on serverB. And when ServerA backs online all requests (Input or Output ) route to ServerA and Stop App on ServerB.

clinfo
clinfo(1M) System Administration Commands clinfo(1M)
NAME
clinfo - display cluster information
SYNOPSIS
clinfo [-nh]
DESCRIPTION
The clinfo command displays cluster configuration information about the node from which the command is executed.
Without arguments, clinfo returns an exit status of 0 if the node is configured and booted as part of a cluster. Otherwise, clinfo returns
an exit status of 1.
OPTIONS
The following options are supported:
-h Displays the highest node number allowed to be configured. This is different from the maximum number of nodes supported in a given
cluster. The current highest configured node number can change immediately after the command returns since new nodes can be dynami-
cally added to a running cluster.
For example, clinfo -h might return 64, meaning that the highest number you can use to identify a node is 64. See the Sun Cluster 3.0
System Administration Guide for a description of utilities you can use to determine the number of nodes in a cluster.
-n Prints the number of the node from which clinfo is executed.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
This is usually because the node is not configured or booted as part of a cluster.
