Need Help On Solaris Cluster Steps For San Migration

I am going to do a SAN Array migration and need the sequence of steps required on the Solaris cluster before moving the old array luns to new array luns.

Here are the steps and I need info on the bold points Smilie

I might even be wrong on the sequence of steps please correct me if I am wrong)

1. need to move all the cluster services to a single node
2. perform host remediations on the node 2
3. reboot node 2 and move the cluster services to node 2
4. perform host remediations on node 1
5. reboot node 1 and move the cluster services to node 1, shutdown node 2
6. perform the cleanup steps to remove old array luns
7. make sure that the applications dont come back automatically on reboot
8. make necessary changes so that when we reboot the node 1 will be able to use new array luns( because after this step we will remove the old array luns and present new array luns)
9. shutdown node 1
10. start Array migration procedure from old array to new array
11. once we are comfortable with the percentage completed we can turn on node 1
12. turn on node 1 and mount the new volumes from new array
13. turn on node 2 and failover to node 2 to check cluster services are running properly
14 once everything looks fine( this finishes the migration)

4S-BACKEND_SETUP(1J)						      4store						      4S-BACKEND_SETUP(1J)

NAME

     4s-backend-setup -- Create a new 4store KB

SYNOPSIS

     4s-backend-setup kbname [--node node-number] [--cluster cluster-size] [--segments segment-count] kb-name

		      --node  Number of this node in the cluster, values range from 0 to cluster-size - 1.  The default is 0.

		      --cluster
			      The number of nodes in the cluster.  The default is 1.

		      --segments
			      The number of segments in the cluster. The default is 2. We recommend one for each CPU core in the cluster as a good
			      starting point. Higher numbers tend to consume more resources, but may result in increased performance.

NOTES

     Once crated with 4s-backend-setup KBs should be started with 4s-backend(1)

SEE ALSO

EXAMPLES

     $ 4s-backend-setup --node 0 --cluster 1 --segments 4 demo

     Creates the indexes for a single-machine KB with four segments, named "demo".
