Thank you very much MichaelFel, can you please tell ( if you have doc/link handy ) what is the fundamental diff of CAA between 7.1.0 and 7.1.1 ?
And what if .. i do follow the below steps ...
1 ) Put the cluster at UNMANAGE STATE
2 ) CAA_FORCE_ENABLED=1
3 ) /usr/sbin/rmcluster -n cluster_name
4 ) upgrade PowerHA using smitty update_all ( updating PowerHA software from 7.1.0 to 7.1.3 ) to all the nodes.
5 ) Create the CAA cluster by running the /usr/es/sbin/cluster/utilities/clmkcaa command
6 ) Run Sync and Verify the cluster.
7 ) Move all the RGs from one Node1 to Node2, reboot Node1
8 ) Once Node1 rebooted start cluster Services on Node1 and move all the RGs from Node2 to Node1 and reboot Node2
9 ) Once Node2 is rebooted, Start cluster services and redistribute the RGs.
This sounds me bit CRAZY ..

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 dynam- ically 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. ATTRIBUTES
