Deleting a cluster
When you delete a cluster, cluster resource services ends on all active cluster nodes and they are removed from the cluster.
You must have at least one active node before
you can delete a cluster. If you have switched disks or other switchable
devices in your cluster, you must first remove each node from the
device domain before you delete your cluster. Otherwise, you might
not be able to add the disks back into another cluster.
To delete a cluster using the PowerHA® graphical interface,
follow these steps: 
- In a Web browser, enter http://mysystem:2001, where mysystem is the host name of the system.
- Log on to the system with your user profile and password.
- Click PowerHA from
the IBM® Navigator
for i window.
- On the PowerHA page,
select Delete Cluster from the Select Action
menu next to the cluster name.
- Click Yes on the
confirmation panel.
