Deleting clusters
Use this task to remove a cluster and all of its cluster members.
Before you begin
In a production environment, avoid deleting clusters that are carrying workload. You can, however, add and remove cluster members during production. When you want to remove a cluster, create a new cluster, adding new members while the old cluster is still operational. After the new cluster is working, remove the cluster members from the old cluster and then delete the cluster.
Tip: If the cluster you are removing has
applications
or modules mapped to it, remap the modules to another cluster, or
create
a new cluster and remap the modules to the new cluster, before removing
the
old cluster. After a cluster to which modules are mapped is deleted,
the modules
cannot be remapped to another cluster. Therefore, if you do not remap
the
modules to another cluster before deleting the old one, you must uninstall
all of the modules that were mapped to the old cluster, and then reinstall
them on a different cluster.
