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:( I might even be wrong on the sequence of steps please correct me if I am wrong)
- need to move all the cluster services to a single node
- perform host remediations on the node 2
- reboot node 2 and move the cluster services to node 2
- perform host remediations on node 1
- reboot node 1 and move the cluster services to node 1, shutdown node 2
- perform the cleanup steps to remove old array luns
- make sure that the applications dont come back automatically on reboot
- 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)
- shutdown node 1
- start Array migration procedure from old array to new array
- once we are comfortable with the percentage completed we can turn on node 1
- turn on node 1 and mount the new volumes from new array
- 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)
